Detailed Description

In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Research shows that the screen size of the existing wearable device (such as a smart watch, a smart bracelet and the like) is smaller, all contents can be only displayed on the small screen, and only some short message contents can be displayed, and the playing of video data cannot be realized, which causes inconvenience to users.

In order to solve the problems in the prior art, the embodiment provides a wireless screen projection method, and in specific implementation, the embodiment first obtains a screen projection instruction, and generates a screen projection connection request according to the screen projection instruction; establishing communication connection with target equipment according to the screen projection connection request; and acquiring video data, and projecting the video data to the target equipment for playing. In the embodiment, the screen projection connection request is generated and the communication connection is established with the target equipment, so that the video data can be projected to the target equipment for display, the screen projection expansion between the wearable equipment and the target equipment is realized, and convenience is provided for the use of a user.

For example, when a user needs to perform screen projection display on video data on a smart watch, a screen projection instruction input by the user is received (for example, a certain screen projection application on a screen of the smart watch is clicked), and then a screen projection connection request is generated according to the screen projection instruction. And establishing communication connection with a television (namely target equipment) according to the screen projection connection request, and then projecting the video data to the television for playing. The whole process is simple to operate, wireless screen projection can be achieved, and convenience is brought to users.

Exemplary method

The wireless screen projection method in the embodiment can be applied to wearable equipment, and the wearable equipment can be miniaturized intelligent products such as a smart watch and a smart bracelet. As shown in fig. 1, the wireless screen projection method includes the following steps:

and S10, acquiring a screen projection instruction, and generating a screen projection connection request according to the screen projection instruction.

The screen projecting instruction in this embodiment refers to an instruction for opening a screen projecting function of the wearable device, for example, a screen projecting button provided on the wearable device, and when the user presses the screen projecting button, the screen projecting instruction can be sent out, or a screen projecting application is provided on the wearable device, and after the user enters the screen projecting application, the user clicks a start button in the screen projecting application, so that the wireless screen projecting function can be started, and the screen projecting instruction is sent out. Then, the wearable device can generate a screen-projecting connection request according to the screen-projecting instruction.

In an implementation manner, the method for generating a screen-casting connection request according to the embodiment includes the following steps when the screen-casting instruction is executed to generate the screen-casting connection request:

s101, acquiring a screen projection instruction, and acquiring terminal equipment in a preset range according to the screen projection instruction;

and S102, generating a screen projection connection request according to the acquired terminal equipment.

During specific implementation, after receiving the screen projecting instruction, the wearable device scans the terminal device within the preset range according to the screen projecting instruction, and acquires the terminal device within the preset range. For example, after the wearable device receives the screen-projecting instruction, the device scanning function is started, and at this time, the wearable device scans the terminal device within a range of 10 meters based on the device scanning function, acquires the device information of the scanned terminal device, and generates a screen-projecting connection request. The screen-casting connection request in this embodiment refers to a desire of the wearable device to establish communication connection with the terminal device within a preset range, and therefore, after the wearable device scans the terminal device, the screen-casting connection request is generated based on device information of the terminal device, and the device obtained through scanning at this time is the target device.

In an implementation manner, if the number of the terminal devices obtained by scanning the wearable device is multiple, it indicates that multiple terminal devices exist in a preset range, and at this time, the wearable device can screen the terminal devices obtained by scanning, and finally determines one terminal device, and the determined terminal device is the target device. For example, when the wearable device determines a target device based on a plurality of terminal devices, the wearable device may perform screening according to a distance between the wearable device and the terminal devices, and when the wearable device is applied specifically, the terminal device closest to the wearable device may be selected as the target device, and the screen-casting connection request may be generated based on device information of the target device.

For example, the terminal devices in the room obtained by scanning the smart bracelet of the user include a television, a smart projector, a computer and the like, and since there are three terminal devices at this time, in order to determine the target device, the smart bracelet respectively obtains the position information of the terminal devices, that is, the position information of the television, the smart projector and the computer, and then, according to the position information of the television, the smart projector and the computer, respectively determines the distance between the television, the smart projector and the computer and the smart bracelet, the obtained distance between the television and the smart bracelet is 2m, the distance between the smart projector and the smart bracelet is 5m, the distance between the computer and the smart bracelet is 3m, and the distance between the visible television and the smart bracelet is the shortest, so that the television can be determined as the target device, and the smart bracelet needs to establish communication connection with the television, the device information of the television is acquired, and then a screen-casting connection request is generated based on the device information of the television.

And after the wearable device generates the screen-projecting connection request, executing step S20, and establishing a communication connection with the target device according to the screen-projecting connection request.

In this embodiment, the screen-casting connection request is generated based on the device information of the terminal device scanned by the wearable device, and the device information includes information such as a device name. Therefore, the wearable device in this embodiment may establish a communication connection with the target device according to the screen projection connection request, so that video data in the wearable device may be projected onto the target device for playing in the subsequent steps.

In one implementation manner, in this embodiment, when establishing a communication connection with a target device, the following steps are performed:

step S201, extracting information of the screen projection connection request to obtain equipment information in the screen projection connection request;

step S202, determining target equipment corresponding to the equipment information according to the equipment information;

and S203, establishing communication connection with the target equipment according to the target equipment.

In specific implementation, the screen-casting connection request is generated based on the device information of the terminal device scanned by the wearable device, and the screen-casting connection request stores a lot of information, so that the wearable device of this embodiment extracts information from the screen-casting connection request after obtaining the screen-casting connection request, and obtains the device information in the screen-casting connection request. And then determining target equipment corresponding to the equipment information according to the equipment information. Since the device information includes information such as the device name, the present embodiment can obtain the device name of the target device according to the device information. After the device name is determined, the wearable device of the embodiment can establish communication connection with the target device according to the device name.

In an implementation manner, after the device name is determined, the wearable device of this embodiment sends the screen-casting connection request to the target device corresponding to the device name to request to connect to the target device. In this embodiment, the target device is already connected to the wireless network, and therefore, after receiving the screen-casting connection request, the target device responds to the screen-casting connection request information and feeds back network connection information, where the network connection information is network connection information of the wireless network to which the target device is connected. The network connection information in this embodiment includes network address information and network password information. Therefore, after the wearable device receives the network connection information, the wearable device can determine network address information and network password information according to the network connection information, and then establish communication connection with the target device according to the network address information and the network password information.

In an implementation manner, in order to ensure the security of the network connection information, the network connection information in this embodiment is encrypted, so that after the target device in this embodiment acquires the network connection information of the wireless network to which the target device is connected, the target device first decrypts the network connection information to obtain the network address information and the network password information in the network connection information, and uses the network address information and the network password information as the network connection information. Therefore, when the wearable device in this embodiment is in a network distribution, the wearable device does not need to input any network password information, and only needs to acquire the network connection information of the target device, the network can be connected according to the network connection information, so that the network can be quickly accessed. In this embodiment, when the wearable device is connected to the wireless network, the wearable device establishes a communication connection with the target device.

In one implementation, after the wearable device completes the connection with the wireless network, the wearable device further binds with the wireless routing device (the device sending the wireless network) according to the device information of the wearable device. In specific implementation, the embodiment can acquire the device information of the wearable device, then acquire the device ID, the physical address and other information from the device information, and then bind the device ID, the physical address and other information with the wireless router, so that the wearable device can be directly connected with the wireless router when performing network connection next time, and thus, automatic network distribution is realized. When binding is completed, the user may be notified that binding was successful. In addition, the present embodiment can also copy and backup the device information of all the bound terminal devices in the wireless routing device to the cloud server, and when the wireless routing device needs to be replaced, the present embodiment can download the device information stored in the wireless routing device before replacement from the cloud server, and synchronize the device information to the replaced wireless routing device, so as to ensure that all the terminal devices can be normally connected to the wireless network.

For example, after the intelligent bracelet determines that the device name is a television, the screen-throwing connection request is sent to the television to request to connect the television, after the television receives the screen-throwing connection request, the television responds to the screen-throwing connection request information and feeds back network connection information, and after the intelligent bracelet receives the network connection information, the intelligent bracelet can establish communication connection with the television according to the network connection information.

In an implementation manner, when the wearable device in this embodiment connects to a wireless routing device (a device that sends out a wireless network) according to the network connection information, the wireless routing device may further perform network distribution permission verification on the wearable device. Specifically, in this embodiment, when determining the distribution network right of the wearable device, the device information of the wearable device may be obtained, and the device information of the wearable device is analyzed, so as to obtain device identification information from the device information, where the device identification information is information such as a device type, a device ID, and a physical address. Because the equipment information of each wearable equipment is different, the equipment identification information is also different, and different wearable equipment can be distinguished through the equipment identification information. Therefore, the distribution network authority of the wearable device can be analyzed according to the device identification information. Specifically, in an implementation manner, in a specific application, after the wireless routing device determines the distribution network identifier in the device information of the wearable device, the device information of the wearable device may be reported to the cloud server, and the cloud server may store the device information so as to be called in a subsequent step. When the distribution network authority of the wearing device needs to be analyzed in subsequent steps, the embodiment can acquire the device information from the cloud server. When the wireless routing device obtains the device information, the device information can be analyzed to obtain the device identification information. Since the device identification information carries a physical address, and the physical address is a unique identifier of each wearable device, the embodiment verifies the physical address to obtain a verification result, and determines the distribution network authority of the wearable device according to the verification result.

In an implementation manner, the embodiment may match the physical address of the device identification information with a preset white list, and if the matching is successful, the wearable device corresponding to the physical address is said to have the distribution network permission. The white list is preset, and the white list is provided with the equipment information of the wearable equipment with the distribution network authority, so that the white list stores the physical address of the wearable equipment with the distribution network authority. For example, the device information of the smart band and the smart watch is stored in the white list in advance, which means that the smart band and the smart watch have the distribution network authority. In this embodiment, when the distribution network authority of the wearable device is determined, the obtained physical address (i.e., the MAC address) may be matched with the white list, and if the physical address of the wearable device is in the white list, the distribution network authority of the wearable device is determined to be authorized, that is, the wearable device has the distribution network authority. If the physical address of the wearable device is not in the white list, it is determined that the distribution network authority of the wearable device is unauthorized, that is, the wearable device does not have the distribution network authority. The embodiment verifies that the distribution network authority of the wearable device is to determine what device the wearable device wants to connect to the wireless network, and then judges whether the wearable device can be connected to the wireless network, so as to prevent the malicious distribution network. Only when the wearable device is judged to have the distribution network authority, the wearable device can be networked according to the network connection information, and then the wearable device can be in communication connection with the target device.

In this embodiment, the wireless routing device in this embodiment is a WiFi routing device, and therefore, the wearable device and the target device are in communication connection through a WiFi network.

After the wearable device in this embodiment establishes a communication connection with the target device, step S30 is executed to obtain video data, and the video data is projected to the target device for playing.

Specifically, what this embodiment needs to realize is to project the video data on the small-size wearable device to the large-size target device for playing, so as to meet the user's use requirement. Therefore, in the embodiment, the video data on the wearable device needs to be acquired, and then the video data is projected to the target device for playing, so that video playing is performed on the large-size target device, and convenience is provided for the user to use.

In one implementation, the present embodiment includes the following steps when implementing screen projection:

s301, acquiring video data, and coding the video data to obtain coded video data;

and S302, projecting the coded video data to the target equipment through WiFi to play.

In specific implementation, after the wearable device of this embodiment acquires video data, the wearable device first performs encoding processing on the video data to obtain encoded video data. When encoding is performed, the present embodiment first obtains the screen size information of the target device, and performs encoding processing on the video data according to the screen size information to obtain the encoded video data. That is, the encoded video data in the present embodiment is encoded according to the screen size information of the target device, and is adaptable to the target device. Then, the wearable device can project the encoded video data to the target device through WiFi for playing. Specifically, after receiving the encoded video data, the target device performs decoding playing, restores the video data, and performs video playing. The wireless screen projection is carried out through WiFi, and the wireless screen projection mode is the most general wireless screen projection mode at present, wherein the image technology is mature and reliable, the application range is widest, and convenience is brought to users.

For example, after the smart band acquires video data, first screen size information of a television is acquired, the video data is encoded according to the screen size information to obtain encoded video data, and then the smart band can project the encoded video data onto the television through WiFi to be played, so that video projection playing is achieved.

In summary, in the present embodiment, a screen-projecting instruction is first obtained, and a screen-projecting connection request is generated according to the screen-projecting instruction; establishing communication connection with target equipment according to the screen projection connection request; and acquiring video data, and projecting the video data to the target equipment for playing. In the embodiment, the screen projection connection request is generated and the communication connection is established with the target equipment, so that the video data can be projected to the target equipment for display, the screen projection expansion between the wearable equipment and the target equipment is realized, and convenience is provided for the use of a user.
