| 摘 要： | 随着视频会议的发展和普及,人们希望同时能看到远端的多个画面。本文针对H.261编码标准,提出了一种四画面合成算法。该算法的特点是不需要在服务器端进行二次编解码,对基于RTP分组的编码数据,在压缩域直接进行合成,从而节约了服务器端宝贵的处理资源。

| Abstract: | With the development and popularization of video conference,pepole expect to see multi-picture simultaneously from the remote endpoint.This paper presents a scheme to realize the combination of multi-picture for H.261.The peculiarity of this method is that it does not need to code again on the video conference server.This method merges the data in the compressed field based on the RTP coding packets,and it thus economizes the precious resources of server. |
