Method and system for interdynamic processing of video flow based on customer terminal

Abstract

The invention relates to a video flow interactive processing method based on client, and a relative device and system. Wherein, the video flow interactive processing system is used to recognize the video data flow integrally, and when it obtains the interactive logic data flow and the video data flow is decoded at single frame successfully, it will execute inter-frame processing on the video flow. The invention can avoid frequent upgrade and refresh on the application to reduce the cost.

Description

technical field [0001] The invention relates to a client-based video stream interactive processing method, and a device and system for realizing the method. Background technique [0002] At present, the visible video interaction technology is to complete the synthesis of the final picture and sound on the server and encode the synthesized video content into a video stream, that is to say, the playback order of plots / scenes and the video limited by the interactive program logic The background picture, the foreground display element, the audio processing of the accompanying sound, etc. are all implemented on the server side. The function of the client is to receive the encoded video stream and use devices such as TVs, set-top boxes, computers, etc. , rewind and other control commands to realize simple control of the video stream. [0003] like figure 1 As shown in FIG. 1 , a structural diagram of a server-based video stream processing system in the prior art is shown. It c...

Problems solved by technology

These complex interactive video processing techniques are very difficult for traditional centralized interactive video systems

[0006] The logical flow control of interactive video often requires more professional operation knowledge and professional production tools, and also requires a lot of production time, and the generated interactive video content is not easy to modify or adjust in real time, which also causes inconvenience in specific application development

Due to the variety of video file formats and codec algorithms, each has its own strengths, but except for some multimedia video formats whose original design includes interactive applications, most other video formats do not contain index information of chapters and plots. Maintain compatibility and versatility to the greatest extent, and cannot arbitrarily define file formats or add additional metadata stream support, which makes some interactive applications relatively difficult

[0007] Traditional video interaction technology, either the server generates the video picture data stream and then transmits it to the terminal player (specific or universal player) for direct picture playback, or the specially designed video file format is played by a dedicated player, such as Real Network The RM / RMVB format of Microsoft, and the WMV format of Microsoft, the video media formats of the above two companies are hindered from the promotion and application of their interactive functions due to the lack of openness and compatibility design of their players, as well as user habits.
