摘要
移动网络视频传输控制技术的关键问题是如何避免拥塞，并在丢包存在的情况下尽可能提高视频质量。文章基于无线网络平台，为了保证解码端的正确执行，使用了一些传输控制技术来减少传输错误造成的影响，并基于RTCP／RTP协议研究一些视频传输中的关键问题如误差掩盖、差错控制和速率控制等，针对视频传输中的速率控制问题分析了几种方法和思路。
The key problem of video transmission control in mobile network is how to avoid congestion, and improve video quality as much as possible in the case of existing packet loss. Based on the radio net platform, some transmission control techniques are used to decrease the influence raised by the transmission mistake in this paper. And the key problems in some video transmissions are explored based on RTCP/RTP agreement, such as error concealment, error control, rate control, etc.. Several methods and thoughts aiming at the rate control of video transmission are analyzed at last.
