Embodiment Construction

[0084] The present invention is based on existing layered coding techniques. The review code stream is generated through the basic layer, and the review device will review the review code stream. If there is no problem in the review, the review device will forward the basic layer code stream to the receiving end of the receiving user, and the enhancement layer code stream will not pass through the review device. After the user terminal receives all the basic layers plus the enhancement layer, it can decode and reconstruct the total video code stream and watch the program. If the user terminal cannot receive the basic layer, it cannot decode, reconstruct and watch the program.

[0085] The structure schematic diagram of the examination system realizing the technical idea of ​​the present invention is shown in Fig. 4, which mainly includes related equipment of content source, content database, and streaming media server. Review equipment and user receiving end equipment, where: ...

Abstract

The invention relates to a video flow inquiring method, system and relative devices, wherein said invention utilizes the relationship between basic layer and strengthen layer of code flow multilayer structure of interlayer code mechanism, to generate inquire code flow; the inquire code flow comprises basic layer code flow, and / or strengthen layer code flow; using special inquirer to inquire and transfer inquire code flow; when the special inquirer inquires out the harmful content in code flow, it will cut off the inquire code flow transmission to the user; user can not decode and rebuild original video flow, to control the transmission of harmful content. The invention can be used to in live broadcast mode and store content play mode.

Description

technical field [0001] The present invention relates to multimedia communication technology, in particular to a video stream review method, system and related equipment implemented based on layered coding in a multimedia communication process. Background technique [0002] As a basic form of multimedia communication, streaming media (Streaming Media) has derived numerous forms of multimedia communication services: conference TV / videophone, IPTV (Internet Protocol Television, IP TV), VOD (Video on Demand, video on demand) , instant messaging, etc. Therefore, streaming media will become the basic communication form on NGN (Next Generation Network, next-generation network). Especially in recent years, with the rapid rise of IPTV services at home and abroad, the application of streaming media on the Internet is also developing rapidly. [0003] A class of services on streaming media, such as IPTV and VOD, all serve to provide video and audio content. The range of content is v...
