The controller 24 performs control of the display device 11. Controller 24 performs control so that each user 13 can perform a content sharing activity in response to a request of each user 13 received from user terminal 12.

Fig. 3 is a block diagram of user terminal 12 according to an example embodiment. The user terminal 12 includes a display 31, a user input device 32, a communicator 33 (e.g., a communication apparatus, interface, and/or transceiver), and a controller 34 (e.g., a processor and/or microprocessor). The user terminal 12 may also include a storage device or storage unit 35. The display 31 displays a UI for sharing content. The user input device 32 receives user input for sharing content. The user input device 32 is not limiting. For example, the user input device 32 may include a touch screen for sensing a touch input by a user on the display 31. The communicator 33 communicates with the first communicator 23 of the display device 11. The controller 34 performs control of the user terminal 12. The controller 34 controls the display 31 to display a UI for sharing content, and controls the communicator 33 to transmit user input received through the user input device 32 to the display device 11 so that the user 13 can perform a content sharing activity.

The communication method between the first communicator 23 of the display device and the communicator 33 of the user terminal 12 is not limited. For example, the communication method may include that at least one of the controller 24 of the display device 11 and the controller 34 of the user terminal 12, such as wireless fidelity (Wi-Fi), bluetooth, etc., may include a control program, a non-volatile memory in which the control program is installed, a volatile memory in which at least a portion of the installed control program is loaded, and at least one microprocessor for executing the loaded control program.

The application may be previously installed or stored in the display device 11 or the user terminal 12 when the display device 11 or the user terminal 12 is manufactured, or may be installed in the display device 11 or the user terminal 12 based on the received data by receiving data of the application from the outside when data of the application is used in the future. The data of the application may be downloaded to the display device 11 or the user terminal 12, for example, from an external server such as an application market.

Fig. 4 illustrates an operation between the display device 11 and the user terminal 12 according to an exemplary embodiment. The first user terminal 41 and the second user terminal 42 shown in fig. 4 refer to two user terminals 12 of the plurality of user terminals 12 shown in fig. 1 to 3, respectively. For ease of description, fig. 4 shows only two user terminals 12 of the plurality of user terminals 12 as an example. Three or more user terminals are also possible according to an exemplary embodiment. First, the first user terminal 41 is connected to the display device 11 and starts communicating with the display device 11 (S41). Any one of the first user terminal 41 and the display device 11 may guide communication between the first user terminal 41 and the display device 11.

If the first user terminal 41 directs the communication, the first user terminal 41 may receive a user input from the user 13 for starting the content sharing activity, e.g. via a UI displayed on the display 31. The first user terminal 41 searches connectable devices around the first user terminal 41 through the UI according to a user input for starting a content sharing activity. If the display apparatus 11 is found to be a connectable device, the first user terminal 41 can connect and communicate with the found display apparatus 11. In this case, when the display apparatus 11 receives a request to search for a connectable device from the first user terminal 41, the display apparatus 11 may connect the first user terminal 41.

Specifically, the first user terminal 41 may determine whether to connect and communicate with the found display apparatus 11 based on information on an Identification (ID) of the display apparatus 11 (e.g., device ID). In this case, if the display apparatus 11 receives a request for searching for a device from the first user terminal 41, the display apparatus 11 may transmit the ID information of the display apparatus 11 itself to the first user terminal 41. The first user terminal 41 may further include a storage device 35 for storing in advance ID information of a display device to be connected for communication, and compares the ID information of the display device stored in the storage device 35 with the ID information received from the found display device 11, thereby determining whether to connect and communicate with the display device 11.

According to an exemplary embodiment, the first user terminal 41 may determine whether to connect the found display apparatus 11 and communicate with the display apparatus 11 according to a user input. Specifically, the first user terminal 41 displays information (e.g., device name, device description, etc.) related to the found display apparatus 11 and a message inquiring whether to connect with the display apparatus 11 on the display 31, and determines whether to connect with the display apparatus 11 and communicate with the display apparatus 11 according to a user input received through the user input apparatus 32. The first user terminal 41 may be connected with the display device 11 by touch using Near Field Communication (NFC) with the display device 11 or a remote controller (described later) of the display device 11.

On the other hand, the display device 11 may guide communication between the first user terminal 41 and the display device 11. The communication guided by the display device 11 can also be realized as in the above case where the first user terminal 41 guides the communication. In this case, the display means 11 may further comprise user input means 25 (see fig. 2) for receiving a user input for starting the content sharing activity. The user input means 25 of the display means 11 may comprise: a panel input part provided in the main body of the display device 11 and directly receiving a user input, and/or a remote control signal receiver for receiving a remote control signal corresponding to the user input from a remote controller for receiving the user input. The display device 11 may further include a storage device or storage unit 26 (see fig. 2) for storing in advance ID information of the user terminal to be connected for communication.

Referring again to fig. 4, the second user terminal 42 is connected to and communicates with the display device 11 (S42). The communication between the second user terminal 42 and the display device 11 can be realized like the above-described communication between the first user terminal 41 and the display device 11. Alternatively, the second user terminal 42 receives information on connection with the display apparatus 11 from the first user terminal 41, and thus connects with the display apparatus 11 based on the received connection information. Alternatively, the second user terminal 42 may provide the first user terminal 41 with information about the connection with the second user terminal 42, and thus allow the first user terminal 41 to transmit the connection information to the display device 11, thereby allowing the display device 11 to be connected with the second user terminal 42.

Alternatively, one user 13 may use two or more user terminals 12. For example, one user 13 may use his/her own smart phone and smart watch as the user terminal 12. In this case, the smart phone in the user terminal 12 may be used to connect with the display device 11 on behalf of a certain user, and then the smart watch in the user terminal 12 may be used to connect with the display device 11 on behalf of the same user as described above. The smart watch user terminal 12 may be connected to the smart phone user terminal 12 using a communication method such as bluetooth, share information with the smart phone user terminal 12, and connect to the display device 11 using Wi-Fi, for example. If one user uses two or more user terminals 12, the display device 11 may display the user and the content control state for the two or more user terminals 12, or may display the content control state differently according to the user terminals 12.

Next, the first user terminal 41 selects content to be shared (S43). The first user terminal 41 displays a UI on the display 31 that allows the user 13 to select desired content.

Fig. 5 illustrates an example of a UI displayed on the user terminal 41 according to an exemplary embodiment. The UI 51 shown in fig. 5 includes a first area 52 showing one or more items 54 corresponding to respective pieces of content selectable as content to be shared, and a second area 53 showing items 55 corresponding to content selected as content to be shared. The displaying of the items 54 and 55 may include displaying information related to the respective content, such as at least one of a thumbnail image, a name, a description, etc. of the content. As shown in fig. 5, the items 54 may be displayed as icons 46 and corresponding content titles 48.

The user 13 may enter by touching the first area 52 to search for content to share, which may be stored in a storage device, for example. For example, the first user terminal 41 may have a first search function, which may be performed via a touch input received through the UI displayed on the first area 52. For example, when the user makes an input 57 of sliding up and down on the first area 52, the first user terminal 41 moves up and down the item 54 of the content shown on the first area 52, and thus appears the item 54 corresponding to the content not shown on the first area 52 by attachment.

The user 13 can move a content desired to be shared among the plurality of contents respectively indicated by the items 54 shown on the first area 52 to the second area 53. For example, if the user 13 makes an input 56 on the icon 46 or the corresponding content title 48 to drag and drop an item 54 of a particular content from the first area 52 to the second area 53, the first user terminal 41 may move the item 54 of the corresponding content to the second area 53. Then, the first user terminal 41 displays the item 55 of content corresponding to the mobile item 54 to additionally appear on the second area 53. Alternatively, the user input device 32 of the first user terminal 41 may sense the intensity (pressure) of the touch input on the display 31 through a predetermined range, and when the item 54 corresponding to the content is pressed with an intensity stronger than a predetermined level in a state where the item is touched and held, the first user terminal 41 displays the item 54 of the content to be moved to the second area 53. The first user terminal 41 may further include a sensor 36 (see fig. 3) for sensing movement or inclination of the first user terminal 41, and when the first user terminal 41 moves or inclines in a preset pattern in a state where the user 13 touches and holds the item 54 of content, the item 54 of content to be moved to the second area 53 is displayed.

According to an exemplary embodiment, if the user 13 moves the item 54 of content from the first area 52 to the second area 53, the first user terminal 41 may determine that the corresponding content is selected for sharing. In this case, in response to adding the item 55 of new content to the second region 53, the first user terminal 41 may display the item 55 of content moving in a direction 59 towards an edge region of the UI 51. At this time, if the item 55 of content reaches the top of the second area 53, the item 55 disappears from the second area 53.

According to an exemplary embodiment, if there is an input of the user 13 after adding the item 55 of new content to the second area 53, the first user terminal 41 may determine that the content corresponding to the item 55 displayed on the second area 53 is selected for sharing. For example, if the user makes an input to tilt the first user terminal 41 toward the display device 11 (i.e., in the upward direction 591), the first user terminal 41 may determine that the user selects the content of the second region 53 for sharing. As the first user terminal 41 is tilted in the upward direction 591, the first user terminal 41 may display the item 55 of content shown in the second area 53 moving in the upward direction 59. The item 55 of content that reaches the top of the second area 53 disappears from the second area 53. Accordingly, the user can see a visual effect as if the content desired to be shared is moved or poured from the first user terminal 41 to the display device 11.

Referring back to fig. 4, if a content to be shared is selected, the first user terminal 41 transmits information about the selected content to the display device 11 (S44). Similarly, the second user terminal 42 selects content to be shared according to the user input (S45), and transmits information about the selected content to the display device 11 (S46).

The display device 11 may display the content to be shared based on the information related to the content received from the first user terminal 41 and the second user terminal 42 (S47). The display device 11 can display the shared content according to the respective users 13.

Fig. 6 illustrates an example of a UI displayed on the display device 11 according to an exemplary embodiment. The UI 61 shown in fig. 6 may include one or more items 62 showing users who share content and one or more items 63 showing shared content. The item 62 showing the users 13 sharing the content with each other refers to the user 13 of the first user terminal 41 and the second user terminal 42 currently connected to the display device 11. Items 62 showing users 13 sharing content with each other may distinguish users 13, for example, by color, name, ID, etc. When the first user terminal 41 or the second user terminal 42 is connected to the display device 11, the display device 11 may assign different colors to the users 13 of the connected first user terminal 41 and the connected second user terminal 42. The display device 11 may transmit information on colors respectively assigned to the users 13 to the first user terminal 41 or the second user terminal 42 of the corresponding user 13.

When receiving the information related to the shared content from the first user terminal 41 and/or the second user terminal 42, the display device 11 may display the item 63 of the shared content (S44, S46). The display device 11 may display that the item 63 of shared content appears on the UI 61 as if it is moving in a predetermined direction. For example, the item 63 of shared content may appear on the UI 61 as if it is moving from right to left or left to right. The display device 11 may display the item 63 of shared content entering the UI 61 as if it landed down from the top of the UI 61 or as if it rose up from the bottom. Thus, a more emphasized visual effect is given as if the content is poured out from the first user terminal 41 and/or the second user terminal 42 to the display device 11.

The item 63 showing the shared content may include a thumbnail image, name, description, etc. of the shared content. The items 63 showing shared content may be distinguished according to the users 13 by the color assigned to the users 13 of the respective content. Therefore, the user 13 can easily recognize which user 13 shares the content through his/her own terminal based on the color that the item of the shared content displayed on the display device 11 has.

Each user 13 can control the shared content displayed on the display device 11 using his/her own first user terminal 41 or second user terminal 42. The operations of the first user terminal 41 and the second user terminal 42 may be similar to each other. For convenience of description, the operation of the first user terminal 41 will be representatively described.

Fig. 7 illustrates an example of a UI displayed on the first user terminal 41 according to an exemplary embodiment. The UI 71 shown in fig. 7 may include: an item 72 for ordering the shared content displayed on the display device 11, an item 73 for navigating the shared content, an item 74 for starting reproduction of the shared content, an item 75 for jumping to the next shared content, an item 76 for voting for the shared content, and an item 77 for controlling the volume of the shared content being reproduced. According to an exemplary embodiment, the first user terminal 41 may display the UI 71 with a color assigned to the corresponding user 13 based on information received from the display device 11. Therefore, the user 13 can easily know the color given to him/her.

The user 13 selects one item from the plurality of items 72 to 77 of the UI 71, and thus controls reproduction of the shared content displayed on the display device 11 (see S48 and S49 in fig. 4). If a user input such as a touch on the UI 71 selects one item from among the plurality of items 72 to 77 on the UI 71, the first user terminal 41 transmits reproduction control information corresponding to the selected item (one of the items 72 to 77) to the display device 11 (see S491 and S492 in fig. 4). The display device 11 displays the reproduction control state of the shared content displayed thereon based on the reproduction control information received from the first user terminal 41 (see S493 of fig. 4). The display device 11 can distinguishably display the reproduction control state of the shared content according to the user 13.

Specifically, if an item 72 for sorting shared content is selected on the UI 71 shown in fig. 7, the first user terminal 41 may display a UI 81 including a menu item 82 showing sortable categories, as shown in fig. 8. For example, the orderable categories of the menu items 82 may include type of content, user, time, vote approval, vote reverse peer. The user 13 may select one category from the orderable categories of the menu items 82, thereby ordering the shared content displayed on the display device 11.

Referring again to fig. 6, the display means 11 may sort and display the items 63 of shared content according to the category selected in the menu item 82 of the first user terminal 41. For example, if a genre or a category of the user is selected, the display device 11 may display only the items 63 of the shared content corresponding to the selected genre or user. If a category of time is selected, the display device 11 may sort the plurality of items 63 of shared content in chronological order such as year, month, day of the week, etc. If a category of voting approval or voting disapproval is selected, the display means 11 may display only the items 63 that obtain shared content that is prioritized or higher than the value determined by voting. As shown in fig. 6, the UI 61 of the display device 11 may further include one or more items 64 for displaying a preference or rating for each piece of shared content.

Referring back to fig. 7, the user 13 may navigate the shared content based on the item 73 of the UI 71 selecting the shared content to be reproduced. For example, the user may slide the item 73 of the UI 71 in the up-down direction 78. The display means 11 may display a plurality of items 63 of shared content while focusing on the currently selected item or items 65, as shown in fig. 6. For example, the focus of the respective items 65 may be distinguished from each other by different colors according to the user 13 selecting the respective item 65. The display device 11 may move the focus to the selected item of shared content 65 in accordance with the user input swipe direction 78 to the item 73 of the first user terminal 41.

Referring again to fig. 7, the user 13 may use the item 74 of the UI 71 to start reproducing the selected shared content. For example, the user 13 checks whether the shared content of the item 65 focused on by the display apparatus 11 is a content that he/she desires to reproduce, and selects the item 74 of the UI 71, thereby starting reproduction of the corresponding shared content. Alternatively, the user 13 may perform a press or a drag to the left or right with an intensity stronger than a predetermined level while sliding the item 73 in the up-down direction 78, thereby starting reproduction of the corresponding shared content.

In response to selection of the item 74 of the first user terminal 41, the display device 11 may start reproducing the shared content of the currently focused item 65. According to an exemplary embodiment, the display apparatus 11 may use the currently reproduced shared content as the wallpaper image of the UI 61. For example, if the shared content currently being reproduced is music, the wallpaper image of the UI 61 may include album art of the music or an image related to the music extracted from an additional image received from an external server or the like.

The display device 11 may receive data of shared content to be reproduced from the first user terminal 41 of the user 13 who requested reproduction and reproduce the corresponding shared content based on the received data. A method of transmitting data of shared content to be reproduced between the display apparatus 11 and the first user terminal 41 is not limited, but the data may be transmitted by a download method or a streaming method. Alternatively, the display apparatus 11 may receive data of shared content to be reproduced from one or more content storage devices or units 14 other than the first user terminal 41 of the user 13 who requested reproduction. The content storage device 14 may include, for example, a Personal Computer (PC), a smart phone, a smart tablet, a Universal Serial Bus (USB) memory, a server, etc., as shown in fig. 1. Referring to fig. 2, the display apparatus 11 may receive data of the shared content to be reproduced from the content storage device 14 through the first communicator 23, or may further include a second communicator 27 (see fig. 2) using a different communication method from the first communicator 23 so as to receive data of the shared content to be reproduced from the content storage device 14 through the second communicator 27. The second communicator 27 may comprise at least one of a communication device, an interface, and a transceiver.

According to an exemplary embodiment, the first user terminal 41 provides a UI for searching for shared content, and transmits information related to a search query input through the UI to the display device 11. The display apparatus 11 may search for the shared content from the content storage device 14 based on information related to a query for searching for the shared content received from the first user terminal 41, and provide the user 13 with a result of searching for the shared content.

The display device 11 can perform data processing for reproducing the shared content. Data processing for reproducing the shared content may be implemented corresponding to the format or attribute of the content. The display device 11 can output a result of processing data of shared content to be reproduced. For example, the display device 11 may output an audio signal of the shared content to be reproduced, or display a moving image or a still image of the shared content to be reproduced. To achieve such an operation, the display device 11 may further include at least one of an audio processor for processing audio data and a speaker for outputting an audio signal. As another example, the display apparatus 11 may transmit a result of processing data of shared content to be reproduced to an external device.

Referring again to fig. 7, the user 13 may select an item 75 of the UI 71 while reproducing the shared content and skip to the next shared content. In response to selection of item 75 in the first user terminal 41, the display means 11 starts reproducing the shared content of item 63 next to the currently focused item 65.

The user 13 may select the item 76 of the UI 71 shown in fig. 7 in order to improve the preference for the desired shared content. In response to selection of an item 76 in the first user terminal 41, the display device 11 enhances the preference for the shared content specified by the user 13. The display device 11 stores a value corresponding to the preference for each piece of shared content in the storage device 26, and changes the value corresponding to the preference for the shared content stored in the storage device 26 as the user 13 develops the preference for the shared content. The preference or rating of the shared content may be lowered according to the selection of the user 13.

The user 13 can control the volume of the shared content being reproduced by selecting the item 77 of the UI 71 shown in fig. 7. For example, the user 13 may slide over the item 77 in a clockwise or counterclockwise direction 79 to turn the volume up or down. The display device 11 adjusts up or down the volume of the shared content (e.g., music or moving images) currently being reproduced according to the direction of sliding on the item 77 of the first user terminal 41.

The display device 11 can display the reproduction control state of each user 13 according to the shared content being reproduced. For example, the display device 11 may display a visualization effect having the following visual effects: a visual effect that varies instantaneously depending on the state in which each user 13 manipulates the user terminals 41, 42 to control reproduction of the shared content. The display device 11 may distinguish the visual effect having this visual effect between the users 13.

Fig. 9 is an enlarged view of the area "a" in the UI 61 shown in fig. 6. As shown in fig. 9, the display device 11 may display a grid 91 having a lattice pattern assigned to the user 13 sharing content as the visual effect or visualization effect. For example, each grid 91 may be distinguished by a color according to the user 13.

The display device 11 receives information on a user control state for controlling reproduction of the shared content from each of the user terminals 41 and 42. For example, the user control state for reproducing the shared content may include each movement or tilt of the user terminals 41 and 42. As shown in fig. 9, if the user 13 tilts the first user terminal 41 in the left direction 92 in order to control reproduction of the shared content, the first user terminal 41 sends information about the tilt direction 92 to the display device 11. The display device 11 may display the grid 91 corresponding to the first user terminal 41 to be transformed in a direction 93 corresponding to the tilt direction 92 of the first user terminal 41 based on the information received from the first user terminal 41. Accordingly, each user 13 can interact with the screen of the display device 11 while viewing the visual effect that instantly reflects the control state of his/her control of the reproduction of the shared content, thereby obtaining a more interesting shared content experience. The visualization effect described in the exemplary embodiment is merely an example of a method of displaying the reproduction control state of each user 13 for the shared content to be distinguished according to the user. In other words, the inventive concept is not limited to this visualization effect.

Fig. 10 illustrates another example of a UI displayed on the user terminal 12 according to an exemplary embodiment. Fig. 11 to 19 are other examples of UIs displayed on the display device 11 according to an exemplary embodiment. With regard to the display apparatus 11 and the user terminal 12 according to the exemplary embodiments shown in fig. 10 to 19, descriptions regarding elements identical or similar to those of the display apparatus 11 and the user terminal 12 described with reference to fig. 1 to 9 will be omitted.

As shown in fig. 10, the first user terminal 41 may display a UI 101 for controlling reproduction of shared content. In the exemplary embodiment, the reproduction of the shared content relates to various cases in which the user 13 is allowed to use the shared content through the display device 11. For example, the reproduction of the shared content may include reproducing a moving image through the display device 11, displaying a photograph, playing music, providing related information related to the content, and the like.

According to an exemplary embodiment, the UI 101 may include a cursor 102 and items 104 and 105 for selecting a category of shared content or sorting and/or arranging shared content. The user 13 manipulates a cursor 102 shown in the UI 101 of the first user terminal 41 and moves the first user terminal 41, thereby controlling reproduction of the shared content displayed on the display device 11. The first user terminal 41 transmits information about the movement of the cursor 102 and the first user terminal 41 to the display device 11, and the display device 11 performs an operation related to controlling to reproduce the content based on the information received from the first user terminal 41.

As shown in fig. 11, the display device 11 may display a UI 111 for controlling reproduction of shared content. The UI 111 displayed on the display device 11 may include a cursor 112 and an item 113 showing shared content. The cursor 112 is displayed corresponding to the first user terminal 41 and the second user terminal 42, respectively. The cursor 112 may be distinguished by colors respectively assigned to the users 13. The cursor 112 displayed on the display device 11 may be shaped to correspond to the cursor 102 displayed on the UI 101 of the first user terminal 41 and the second user terminal 42.

The item 113 showing the shared content may include at least one of a thumbnail image, a name, and a description of the content. There is no limitation on the pattern in which the plurality of items 113 sharing content are arranged. In an exemplary embodiment, the items 113 may be randomly arranged. Alternatively, the items 113 showing shared content according to an exemplary embodiment may be arranged to have various patterns, for example, a 3D spherical pattern or the like.

Each item 113 showing shared content may be displayed as if it landed down from the top of the UI 101 (reference numeral 114). The displayed item 115 may be animated to move as if it were submerged (reference numeral 116). The size of the item 113 showing shared content may be determined based on the amount of shared content to be displayed.

Fig. 12 shows the UI 121 that displays more shared content than the content displayed on the UI 111 shown in fig. 11. As shown in fig. 12, the items 122 respectively corresponding to the shared contents displayed on the UI 121 may be smaller than the item 113 of the shared contents displayed on the UI 111 shown in fig. 11. In addition, the display device 11 may display an image on the wallpapers of the UI 111 and the UI 121, and may enlarge or reduce the wallpaper image according to a size change of the items 113 and 122 of the shared content.

Referring again to fig. 10, the user 13 may move the cursor 112 displayed on the display device 11 by controlling the movement of the first user terminal 41. For example, if the user 13 tilts the first user terminal 41 in the upward, downward, leftward and rightward directions 103, the display device 11 may display that the cursor 112 corresponding to the first user terminal 41 moves in a direction corresponding to the tilting direction 103 of the first user terminal 41. There is no limitation on a method of moving the cursor 112 of the display device 11 by manipulating the first user terminal 41, and various methods are possible.

According to an exemplary embodiment, the user 13 applies movement control to the first user terminal 41 so that the items 113 of shared content may be arranged differently on the display device 11. For example, the user 13 may slide the cursor 102 of the first user terminal 41, or perform movement control of tilting the first user terminal 41 in the upward, downward, leftward, and downward directions 103 in a state where the cursor 102 is touched and held. In this regard, the display device 11 may display all items 113 corresponding to a plurality of pieces of shared content arranged as shown in fig. 11 or 12 moving up, down, left, and right, rotating in a horizontal or vertical direction, and zooming in or out. Accordingly, the user 13 arranges the items 113 of content in various patterns, and more easily selects desired shared content.

The user 13 can specify the item 113 of shared content displayed on the display device 11, thereby selecting shared content desired to be reproduced. The user 13 specifies an item 113 of shared content desired to be reproduced with the cursor 112, and starts reproducing the shared content. The user 13 may use the cursor 112 to select and focus the item 113 of shared content, release the selection, or scroll. The cursor 112 may be displayed with a color assigned to the user 13 currently controlling the cursor 112. The cursor 112 may repeatedly become larger and smaller as it breathes, thereby attracting the user's interest.

Fig. 13 and 14 show details of some items 113 of shared content displayed on the UI 111, the UI 121 shown in fig. 11 and 12. As shown in fig. 13, before the item 113 of shared content is specified with the cursor 112, the item 113 of shared content is displayed to have the basic form described with reference to fig. 11 and 12. In particular, the items 113 of shared content may be tagged with an identifier 133 indicating to which user 13 the respective shared content belongs. The color of the identifier 133 may be the same as the color assigned to the corresponding user 13 sharing the content. The items of shared content 113 may display thumbnail images 134 of the respective shared content. The items of shared content 113 may display information 135 related to the source of the respective shared content (i.e., the source that provided the respective shared content). According to an exemplary embodiment, the source information 135 of the shared content may not be displayed when the source is the first user terminal 41, but the source information 135 of the shared content is displayed only when the source is, for example, a web page, an external device, or a similar content storage device 14 (see fig. 1).

Next, when the item 113 is designated with the cursor 112, the item 113 of the shared content may be highlighted to indicate focusing on the item 113 (see 137 in fig. 13). The protrusion 137 may be displayed around the edge of the item 113 and may be shaped, for example, as a rectangle. The protrusions 137 may have the same color as the identifier 133 of the corresponding shared content. When focusing on the item 113 of shared content, additional information 138 of the shared content may be displayed. The additional information 138 of the shared content may include a title and description of the corresponding shared content, information provided by a specific service when it is connected to the specific service, and the like. For example, the information provided by the corresponding service may be given in the form of the number of stars indicating the level of recommended content, as shown in fig. 13.

Next, in a state of focusing on the item 113 of the shared content, the user 13 can select the item 113 so that the shared content can be reproduced. Referring to fig. 10, the user 13 may manipulate the cursor 102 of the first user terminal 41 to select an item 113 of the display device 11.

As shown in fig. 13, when an item 113 of shared content is selected by an input of the user 13, the display device 11 may display that the cursor 112 on the item 113 becomes small as if it were grasping the item 113 like a hand of the user 13. Therefore, the user 13 can select the shared content more interestingly because the shape of the cursor 112 varies depending on his/her manipulation.

Fig. 15 illustrates an example of the UI 141 displayed on the display device 11 according to an exemplary embodiment. If the item 113 of shared content is selected in response to the input of the user 13, the display device 11 reproduces the shared content 142 corresponding to the selected item 113. Fig. 15 shows an example of displaying information provided on a network as one of reproduction shared content 142. However, there is no limitation on the type of reproduction of the shared content. According to an exemplary embodiment, if the shared content is a moving image, the moving image may be reproduced. If the shared content is a still image, the still image may be displayed. Similarly, the shared content may be differently reproduced according to the kind and format of the shared content.

According to an exemplary embodiment, the display device 11 may arrange and display the items 113 of shared content differently.

Fig. 16 and 17 illustrate examples of the UI 151, the UI 161 displayed on the display device 11 according to the exemplary embodiment. As shown in fig. 16 and 17, the items 113 of shared content are arranged in the form of a two-dimensional grid or matrix in the UI 151 and the UI 161. The display device 11 may display the UI 151, the UI 161 in response to an input of the user 14 to the first user terminal 41. In response to an input to the first user terminal 41 by the user 14, the display device 11 can switch between the arrangement of the items 113 corresponding to the shared content shown in fig. 11 and 12 and the arrangement of the items 113 corresponding to the shared content shown in fig. 16 and 17. Accordingly, since the items 113 of the shared content are arranged differently, the user 13 more conveniently selects desired shared content.

As shown in fig. 17, if the cursor 112 reaches an edge, for example, the left edge, of the screen in response to the input of the user 14 to the first user terminal 41, the display device 11 scrolls all the items 113 of the shared content currently displayed to the right (reference numeral 164) so that one or more items 165 of the shared content that have not yet been displayed can enter the screen. As a non-limiting exemplary embodiment, if cursors 112 corresponding to multiple users 13 are displayed, the display device 11 may allow the item 113 of shared content to be movable only when cursors 112 corresponding to all of the multiple users 13 reach an edge. Accordingly, any of the plurality of users 13 can have a sufficient opportunity to view the item 113 of shared content, and thus the convenience of the user can be improved.

According to an exemplary embodiment, the display device 11 may sort and/or arrange the items 113 of shared content according to category.

Fig. 18 illustrates an example of a UI 171 displayed on the display device 11 according to an exemplary embodiment. As shown in FIG. 18, one or more items 113 of shared content are ordered and/or arranged according to categories in the UI 171. The UI 171 may display the respective names 173 of the categories. In the UI 171, the categories are horizontally arranged, and the items 113 of shared content belonging to each category are vertically arranged. The sorting and/or arranging method is not limited to the example shown in fig. 17 and may be varied differently.

Referring again to FIG. 10, the user 13 may use the items 104 and 105 of the first user terminal 41 to select a category of shared content for which ordering and/or ranking is desired. The selectable categories of shared content may include, for example, photos, moving images, music, web page information, etc., as categories of content, or users, genres, preferences, times, etc., as methods of ordering content. There is no limitation on the selectable categories, and the selectable categories may include any category for ordering or ranking the shared content. The first user terminal 41 transmits information on the category of the shared content selected by the user 13 to the display device 11. The display means 11 displays the items 113 of shared content corresponding to the category selected by the user 13 ordered and/or arranged based on the information received from the first user terminal 41. Thus, user 13 may more easily select shared content as desired because items 113 of shared content are ordered and/or arranged differently.

According to an exemplary embodiment, the display device 11 may display that the items 113 of the shared content are arranged at a specific position on the wallpaper image.

Fig. 19 illustrates an example of a UI 181 displayed on the display device 11 according to an exemplary embodiment. As shown in fig. 19, the UI 181 may include a wallpaper image 182 and one or more items 113 of shared content arranged on the wallpaper image 182. In an exemplary embodiment, wallpaper image 182 may be a map image, but is not limited thereto. Each item 113 of shared content is displayed at a particular location 184 that matches the shared content on the map image (i.e., wallpaper image 182). For example, if the shared content is information related to a restaurant, the corresponding item 113 may be displayed at a location 184 corresponding to a particular point on the map 182 where the restaurant is located. The user 13 manipulates the first user terminal 41 to move the map (i.e., the wallpaper image 182) up, down, left, and right, or zoom in or out of the map, thereby searching for the items 113 of shared content as needed. Therefore, the user 13 more conveniently selects the shared content as needed.

According to an exemplary embodiment, the display device 11 may provide a function of searching for shared content.

Fig. 20 illustrates an example of a UI 191 displayed on the display device 11 according to an exemplary embodiment. As shown in fig. 20, the UI 191 may include items 192 and 193 of shared content and a search box 194. In response to the user's input to the first user terminal 41, the display device 11 may display a search word 195 corresponding to the shared content that the user 13 desires to search, for example, the country "korea", in the search box 194. The display apparatus 11 searches for shared content corresponding to the search word 195 that is completely input, and displays an item 192 of the searched shared content in the UI 191. The display device 11 may display the searched item 192 of shared content with more emphasis on the item 192 than the item 193 of another shared content displayed before the search so that the user 13 can easily recognize the search result. For example, the searched item 192 of shared content may be arranged at the front, while the other item 193 of shared content may be arranged at the back. The searched item of shared content 192 may be enabled, but the other item of shared content 193 may be disabled. The disabled another shared content item 193 may be displayed more shallowly or more deeply.

The user 13 can start a search function for the shared content through the first user terminal 41 and input a search word for the shared content desired to be searched. Referring again to fig. 10, according to an exemplary embodiment, the user 13 may use the item 105 of the first user terminal 41 to start the search function, but is not limited thereto. When the search function is started, the first user terminal 41 displays a UI for inputting a search word on the screen of the first user terminal 41 so that the user 13 can input the search word. According to an exemplary embodiment, the first user terminal 41 may receive the search term based on the voice input of the user 13, for example, via a microphone provided in the user terminal.

Referring back to fig. 20, the display device 11 may display the search box 194 in the same color as the color assigned to the user 13 currently using the search function, and thus it is easy to know who uses the search function. If the specific user 13 starts the search function, the display device 11 suspends the cursor control corresponding to the specific user 13 and displays the search box 194. When a specific user 13 is using the search function, the display device 11 may prevent another user 13 from using the search function. The search function assigned to a specific user 13 may be valid until the corresponding user 13 inputs termination of the search function or until a predetermined time elapses.

When the search function assigned to the specific user 13 is terminated, the display device 11 releases the display of the search box 194 and resumes the cursor control corresponding to the user 13. Therefore, the user 13 more conveniently selects desired shared content by a search function for the shared content.

According to an exemplary embodiment, if the specific user 13 requests reproduction of the shared content, the display device 11 may start reproducing the requested shared content after a predetermined standby time elapses from the request time point. Thus, another user 13 may have an opportunity to select shared content as she desires during the standby time. The standby time may be individually applied to each piece of shared content, and independently counted from when a request to reproduce each piece of shared content is made.

Referring to fig. 14, the display device 11 may display a timer 1392 showing a standby time on the item 113 of the shared content requested to be reproduced.

The display device 11 may reproduce only the shared content of which the standby time is first ended among the plurality of pieces of shared content requested to be reproduced. The display device 11 may reproduce the plurality of pieces of shared content requested to be reproduced in the order in which the standby time thereof ends. Multiple users 13 may make repeated requests for a piece of shared content. In this case, as the number of users 13 requesting reproduction increases, the standby time may become shorter or may pass through more quickly. In other words, more shared contents requested by the user 13 can be preferentially reproduced. When the plurality of users 13 repeatedly requests the shared content more times, the display device 11 may enlarge the timer 1392, display the timer 1392 three-dimensionally, or give a similar visual effect. Therefore, according to the exemplary embodiment, shared content desired by a plurality of users is preferentially reproduced by considering the preferences of the plurality of users.

Fig. 21 and 22 are other examples of UIs displayed on the display device 11 according to an exemplary embodiment. With regard to the display apparatus 11 and the user terminal 12 shown in fig. 21 and 22, descriptions regarding elements identical or similar to those of the display apparatus 11 and the user terminal 12 shown in fig. 1 to 20 will be omitted.

The UI 201 shown in fig. 21 includes a cursor 112, one or more items 113 displaying shared content, and an item 205 indicating a user and/or preferences. According to an exemplary embodiment, the shared content shown in fig. 21 may be, for example, a photograph, but is not limited thereto. For example, the items 113 corresponding to a plurality of photographs may be arranged in a 2D grid or matrix. Each item 113 of shared content additionally includes an item 205 indicating a user and/or a preference. The item 205 is displayed with the color assigned to each user 13 and thus informs which user terminal shares the corresponding photograph. The shape of the item 205 resembles a bar, so that preference for photos can be indicated by the length of the bar.

The display device 11 moves the cursor 112 in response to user input received from the user terminal 12. The display device 11 focuses on the item 204 of the photograph where the cursor 112 is currently located. For example, the item 204 of the currently focused photograph may be displayed to be larger than the other items 113, and may be tilted at a predetermined angle. According to an exemplary embodiment, referring back to fig. 10, while the display device 11 displays the item 204 of the photograph, if the user 13 touches the UI 101, the first user terminal 41 may make the cursor 102 large. In this case, the display device 11 can make the cursor 112 smaller. Accordingly, the circle of the cursor 102 displayed on the first user terminal 41 is enlarged as if it were pressed down, and the cursor 112 displayed on the display device 11 is reduced as if it were grabbing a photograph, thereby giving the user a more interesting control experience. Alternatively, the cursor 102 displayed on the first user terminal 41 may be made larger or smaller according to the intensity of the user 13 touching the UI 101.

Referring to fig. 22, in response to a user input received from the user terminal 12, the display device 11 may display an editing area 212 at a lower end of the UI 211. Edit area 212 may display an item 213 for creating an album. If the user 13 selects the item 213 via the cursor 112, the display device 11 displays an item 215 of the album to be edited. Each user 13 may move one or more items 113 of a desired photo to an item 215 of the album by drag and drop, etc. Thus, multiple users 13 may make a shared photo album with their desired photos. The display device 11 may additionally display an item 217 to an item 215 of the album, thereby indicating the user of the photos included in the album. The item 217 is displayed in the color (or colors) assigned to the user 13 of each photo included in the album, so it is easy to know whose photos the album includes. The shape of the item 217 may be similar to a bar comprising a color bar, and if the album comprises photos corresponding to a plurality of users 13, the length of each color bar may be proportional to the number of photos of each user 13 included in the album. Therefore, it is easy to know information about the user who created the album.

Fig. 23 is another example of a UI displayed on a user terminal according to an exemplary embodiment. With respect to the UI 221 and the UI 222 of the user terminal 12 shown in fig. 22, the elements identical or similar to those of the UI 71 and the UI 81 of the first user terminal 41 described with reference to fig. 7 and 8 will be omitted. As shown in fig. 22, the UI 221 and the UI 222 are shaped like a circle. For example, the user terminal 12 may be a smart watch or the like. The UI 221 and the UI 222 show different control states, respectively, and include items 225 and 226 corresponding to the control states. Items 225 and 226 showing control status may include, for example, a graphic of a play and a speaker, but are not limited thereto. The UI 221 and the UI 222 may switch with each other in response to an input by the user 13. For example, if the user 13 swipes left or right on the UI 221, 222, or presses the UI 221, 222 with a strength stronger than a predetermined level, the UI 221 and the UI 222 switch with each other.

The UIs 221, 222 include wheels 223 disposed along the edges of the screen. The user 13 may touch and rotate the jog wheel 223 in a clockwise or counterclockwise direction 224. If user 13 rotates scrollwheel 223, the points that form scrollwheel 223 are displayed as if they were rotating in the direction of control of user 13. In a state where the UI 221 is displayed, the user 13 may select desired content among the items 63 of shared content displayed on the display device 11 as shown in fig. 6 while rotating the jog dial 223. The display apparatus 11 can move the focus 65 to the item 63 corresponding to the plurality of pieces of shared content according to the rotation direction 224 of the jog dial 223 by the input of the user 13. In a state of focusing on the item 65 of the desired shared content, the user 13 can select reproduction of the corresponding shared content. For example, if the user 13 selects the item 225 of the UI 221, it is possible to select reproduction of shared content corresponding to the focused item 65. Alternatively, if the user 13 presses the jog dial 223 with an intensity stronger than a predetermined level while turning the jog dial 223, it may select to reproduce the shared content corresponding to the focused item 65.

If the user 13 selects the item 225 of the UI 221 when reproducing the selected shared content, the reproduction of the content is suspended. In a state where reproduction of the content is suspended, if the user 13 selects the item 225 of the UI 221, reproduction of the corresponding content is resumed. While the UI 222 is displayed, the user 13 can control the volume or the like of the reproduced shared content when the jog dial 223 is turned.
