A multimedia video conference system: Using region base hybrid coding

In this paper, a video coding algorithm suitable for video conference application, and an investigation of a video conference system over LAN are presented. The proposed video coding algorithm is called region base hybrid coding algorithm. This method can perform foreground and background segmentation. This is based on the characteristic of an unchanged background on most of the video conference applications. This property can reduce both data rate and computation load. The proposed algorithm is verified on a video conference system over LAN, and it can work successfully.
