Abstract

The embodiment of the invention discloses a video session method based on a two-way HFC (Hybrid Fiber Coax) network as well as associated equipment and system. The video session method based on the two-way HFC network comprises the following steps of: obtaining a session media stream parameter by a video session controller; transmitting a first control signaling carrying the session media stream parameter to a video transcoding server; obtaining a transmission stream parameter by the video session controller; and transmitting a second control signaling carrying the transmission stream parameter to a digital television receiving terminal by the two-way HFC network so that the digital television receiving terminal receives, analyzes and plays a transmission stream processed by an edge modulator through the two-way HFC network according to the transmission stream parameter. The technical scheme of the invention can effectively solve the problem of insufficient transmission bandwidth caused by providing multiple paths of video or high-definition video sessions in a video session system and meets the higher requirement of a user on the video session system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a bidirectional HFC network-based video conferencing method and related equipment and system. Background technique [0002] With the popularization of video conferencing system applications and the development of network technology, users will have more comprehensive and in-depth functional requirements for video conferencing systems. Therefore, on the basis of providing basic functions of video conferencing systems, video conferencing systems should also meet the increasingly Increasing user demands, such as the increase in the number of interactive objects in video conferencing, the improvement of video quality, etc., are also requirements for the further improvement of the technical conditions required to realize the video conferencing system. Under more complete technical conditions, video conferencing In order to provide better audio-visual interactive services, in order to...
