多媒体数据流实时传输速率研究及应用 随着多媒体及互联网技术的迅速发展，广泛应用于远程教育、视频会议等的数字视频实时传输的技术已成为计算机领域的一个研究热点。数字视频实时传输过程中数据量巨大且延迟敏感性强，因此，在实时传输中必须对视频数据进行压缩以保证低延迟。-Real-time multimedia data transfer rate of flow and application of multimedia and Internet technology with the rapid development of widely used in distance education, video conferencing, real-time transmission of digital video technology has become a hot topic in the computer field. During the transmission of digital video data in real time and delay sensitive than large, so in real-time transmission of video data must be compressed to ensure low latency.
