INFORMATION INTERACTION MECHANISM AND NETWORK TRANSMISSION METHOD IN MULTIMEDIA SYSTEM

摘要

Provided are information interaction mechanisms of two forms and a network transmission method in a multimedia system. One information interaction mechanism adopts a message interaction body to realize two-way fast information interaction, and is capable of solving the defect of lacking an efficient and flexible two-way information interaction mechanism in the existing media transmission system, and meanwhile can be applied to all media transmission systems; and the other information interaction mechanism simplifies the size of protocol format header data with regard to the simplest data packet enforced by a protocol transmission format so as to adapt a protocol format to fast information interaction. The simplification of the size of the protocol format header data can solve the defect of lacking an efficient two-way fast information interaction mechanism in the existing media transmission system. Meanwhile, an optimal transmission mechanism for still images in a video stream is provided. The mechanism of adding a flag bit to frame data that is stationary relative to an image of a previous frame, and only transmitting information about the flag bit without transmitting the frame data can solve the problems of bandwidth occupation and traffic wastes brought by still image frames in streaming media video transmission.
