Information exchange mechanism and network transmission method in multimedia system

摘要

The present invention provides an information exchange mechanism and a network transmission method in two types of multimedia systems. One of them is to adopt an exchange information agent to realize bi-directional rapid exchange of information, and solve the problem of lack of highly efficient and flexible bi-directional information exchange mechanism in the conventional media transmission system. Can be applied to all media transmission systems at the same time. The other is to simplify the size of the header data of the protocol format so that the protocol format is adapted for rapid information exchange, by forcing the data packet to be minimally configured relative to the protocol transmission format, the protocol By simplifying the size of the format header data, the problem of the lack of a highly efficient, bi-directional, rapid information exchange mechanism in conventional media transmission systems can be solved. At the same time, it provides an optimized transmission mechanism used for still images in the video stream, adds an indicator bit to frame data in which the image of the previous frame is stationary, and transmits only the information of the indicator bit. It does not transmit the frame data mechanism and solves the problem of bandwidth occupation and traffic waste by still image frames in stream media video. [Selected figure] Figure 1
