Abstract

The system thereof comprises: a broadcast wideband video session unit, a video and audio transmission unit and a network management unit. The method thereof comprises: 1) the audio and video signals are compressed into the MPEG-2 data stream; 2) making video and audio collection, switch and remote switch in broadcast level; 3) implementing the broadcast level wideband video session; 4) making inverse multiplexing for the communication line; 5) with TCP / IP, the network management messages are transmitted through packet switch network or PSTN network; 6) using Visual C++ programming language to edit the application software used in video session, video and audio transmission and network management.

Description

technical field [0001] The invention relates to the technical field of audio-image processing and transmission, in particular to an audio-image transmission system and method for a broadcast-level broadband video conference. Background technique [0002] Video conferencing, also known as video conferencing or video conferencing, is a system integrating network, television, computer communication and data sharing technologies. After the system is completed, it is required to be able to hold a network-wide video conference across cities and networks through simple operations in the conference room, watch images or computer data, make major decision-making deployments, and listen to relevant parties' reflections on decisions, etc. [0003] Beginning in the 1960s, developed countries in the world began to study analog video conferencing and gradually commercialized it. At the end of the 1960s, under the impetus of compression coding technology, the analog system turned to the d...
