Detailed Description

The technical scheme of the invention is further explained by combining the drawings and the embodiment.

Referring to fig. 1, the invention discloses an ultra high definition video-on-demand system with a brand new architecture, which is mainly divided into a four-layer structure, and comprises a background service system 1, a front-end service system 2, a radio and television wired network 3 and a terminal 4 according to the flow sequence of ultra high definition content generation and transmission. The background service system 1, the front-end service system 2 and the terminal 4 respectively comprise a plurality of modules. As shown in fig. 1, the background service system 1 includes a content collection module 11, an arrangement management module 12, a service management module 13, a service operation module 14, a template management module 15, a statistical analysis module 16, and a system management module 17. The front-end service system 2 includes a content management module 21, a graphics production module 22, a video production module 23, and a page presentation module 24. The terminal 4 includes a video decoding module 41, a play control module 42, a page parsing module 43, and an authentication module 44.

The background service system 1 is the background of the entire system, and is a system that generates ultra-high-definition content. In the background service system 1, the data transmission relationship among the modules is as follows: the content acquisition module 11 unidirectionally transmits the ultra-high-definition content information to the arrangement management module 12, the arrangement management module 12 bidirectionally transmits the service instruction with the service management module 13, the service operation module 14 unidirectionally transmits the service data to the service management module 13, and the template management module 15 bidirectionally transmits the template information with the content acquisition module 11. The statistical analysis module 16 counts the ultra high definition content information arranged in the arrangement management module 12, and the system management module 17 provides a management interface for the background service system 1.

Compared with the prior art, the invention resets each module in the background service system 1 and sets the specific architecture among the modules, namely the data transmission relation among the modules comprises different one-way/two-way transmission relations. The data transmission relationship not only determines a new architecture, but also determines the module transmission relationship by the module function and determines the architecture of the background service system 1 by the module transmission relationship, which are derived from the definition of each module function.

With further reference to fig. 1, the content collection module 11 collects the ultra high definition content and transmits the ultra high definition content to the arrangement management module 12. When the content acquisition module 11 acquires the ultra-high-definition content, the ultra-high-definition content is communicated with the template management module 15 in real time, so that the template management module 15 can automatically select the most matched template according to the ultra-high-definition program content acquired by the content acquisition module 11 every predetermined period of time. On the other hand, the template management module 15 also has a machine learning function, and can iteratively update the template preset therein according to the matching degree with the content acquisition module 11, so that the template preset therein can be better updated along with the update of the ultra-high definition program content. The content acquisition module 11 sends the ultra-high definition program content to the arrangement management module 12 in a certain template manner, and the arrangement management module 12 performs operations such as editing and typesetting on the ultra-high definition content with the template according to the service instruction. The service instruction of the orchestration management module 12 is from the service management module 13, that is, the orchestration management module 12 receives the service instruction from the service management module 13, and orchestrates the ultra-high definition content according to the service instruction. The service operation module 14 is responsible for generating a corresponding service instruction and unidirectionally sending the service instruction to the service management module 13. In other words, the service management module 13 obtains the service data from the service operation module 14, and generates the service instruction according to the service data. The background service system 1 also has two relatively independent modules, namely a statistical analysis module 16 and a system management module 17. The statistical analysis module 16 counts the ultra high definition content information arranged in the arrangement management module 12 to form a statistical report log and store the statistical report log. The system management module 17 provides a management interface for the entire background service system 1, and includes both a hardware interface and a software interface, such as an input/output interface and a software debugging interface.

As a preferred embodiment of the present invention, the service command transmitted between the service management module 13 and the service operation module 14 includes information of different requirements, types, playing time, playing speed, colors, saturation, definition, and the like, which is only one of the real-time methods of the present invention. The service instructions may include any parameters suitable for the ultra high definition program content format.

The background service system 1 transmits the arranged ultra-high-definition content information to the front-end service system 2, and specifically, the arrangement management module 12 in the background service system 1 transmits the arranged ultra-high-definition content information to the content management module 21 in the front-end service system 2.

With continued reference to fig. 1, the front-end service system 2 is a transition layer between the background and the network, and is configured to receive all the organized ultra-high-definition contents, and classify various ultra-high-definition contents into categories for integrity processing and classification, so that the ultra-high-definition contents can meet the commercial purpose. Compared with the prior art, the invention redefines the respective functions of the modules in the front-end service system 2 and the specific architectures among the modules, namely the data transmission relations among the modules, including different one-way/two-way transmission relations. Furthermore, the redefinition framework of the front-end service system 2 is matched with the redefinition framework of the background service system 1, so that the mutual matching effect is achieved.

In the front-end service system 2, the graphics and text production module 22 has two-way access with the content management module 21, and the video production module 23 also has two-way access with the content management module 21, and the content management module 21 transmits ultra-high definition content to the page presentation module 24 in one way.

The content management module 21 stores and manages the arranged ultra-high-definition content information, that is, receives the ultra-high-definition content transmitted by the arrangement management module 12 in the background service system 1. The content management module 21 stores all the arranged ultra high definition content, and sends the bibliographic information of the stored ultra high definition content to the image-text production module 22 and the video production module 23. The image-text production module 22 adds image-text information to the arranged ultra-high-definition content information according to the corresponding bibliographic information. Similarly, the video production module 23 adds video information to the arranged ultra-high-definition content according to the corresponding bibliographic information. The page presentation module 24 presents the corresponding ultra high definition video content according to the storage of the content management module 21.

As a preferred embodiment of the present invention, the additional graphic information of the graphic production module 22 may be cover information used for ultra high definition content display, including specific images and texts. The video information appended by the video production module 23 may be a small piece of video information that is intercepted from the ultra high definition content as preview information. The information displayed by the page display module 24 may be the bibliographic information of the ultra-high-definition content stored in the content management module 21, cover information (additional graphics and text information) and/or preview information (additional video information) corresponding to the ultra-high-definition content, or any combination of the bibliographic information, the cover information, and the preview information.

The broadcast and television wired network 3 is connected with the front-end service system 2 and the terminal 4 by a network. Specifically, the content management module 21 transmits the ultra high definition content to the terminal 4 through the broadcast/television cable network 3.

The terminal 4 is a program end and a device end for executing ultra-high-definition content playing, and may be any intelligent or non-intelligent playable device, including but not limited to a mobile phone, a PAD, a television, a projector, and the like. The terminal 4 internally includes a video decoding module 41, a play control module 42, a page parsing module 43, and an authentication module 44. The video decoding module 41 is connected to the play control module 42 in both directions, the page parsing module 43 transmits page parsing information to the play control module 42 in one direction, and the authentication module 44 transmits authentication information to the video decoding module 41 in one direction.

In the terminal 4, the authentication module 44 first checks whether the ultra-high-definition content received by the terminal 4 conforms to a specific format, and if so, notifies the video decoding module 41 to start decoding, and if not, notifies the video decoding module 41 to stop working. The video decoding module 41 receives the ultra high definition content transmitted by the broadcast and television cable network 3, decodes the ultra high definition content after the verification of the authentication and authentication module 44 is passed, and sends the decoded ultra high definition content to the play control module 42. The play control module 42 controls the play of the ultra high definition content and checks whether the content in the play buffer is erroneous. If so, the playback control module 42 notifies the video decoding module 41 to re-decode the erroneous portion. After receiving the re-decoding instruction, the video decoding module 41 performs secondary decoding on part of the ultra-high definition content pointed by the instruction. The page parsing module 43 parses the content displayed by the page display module 24, and sends a corresponding instruction to the play control module 42 according to the user's operation, and the play control module 42 executes a corresponding play operation according to the user's instruction.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
