Implementation of a Video Conference Server with Additive Video-Stream

In this paper, we implement a video conference system, which connects remote PCs. Each system receives video and audio data from devices attached to a PC and compresses them by using CODECs. It sends the compressed data to the opponent. Compared to the existing ones, the proposed system can combine two video streams into a new one. Thus, additional video data can be transferred to the opponent during a call.
