Abstract

The invention relates to a bandwidth-adaptive video conference. A video mode is dynamically selected and the scalable video CODEC (SVC) technology is combined with the P2P technology. Besides, an internet service mode is used to provide a virtual video conference room and a desktop video service for an enterprise, thereby saving cost for construction of a video conference room by the enterprise. Moreover, a hiring mode is employed, so that a video conference can be held anywhere at any time.

Description

technical field [0001] The present invention relates to the field of computer and Internet communication, and is specifically applicable to video conferencing on the Internet. Compared with traditional conference room video conferencing, the invention provides an alternative or upgraded video conference on the Internet through the cloud computing mode. Through the bandwidth adaptive technology, the video quality is guaranteed under the condition of limited bandwidth. Background technique [0002] The traditional video conferencing room technology transmits the video streams of each video conferencing room to a central node through a dedicated line. The central node mixes multiple videos into one video through the MCU and sends it to other video conferencing rooms. The MCU controls the video mode and video size of each node to watch the video. The disadvantage of this method is high investment. Video conferences cannot be held without the video conference room. At present, m...
