摘要

在无线信道上传输压缩视频仍然是一项具有挑战性的任务，因为无线信道的噪声特性和压缩视频比特流中的单个比特错误可能导致重构的视频严重失真。文献中提出了许多误差控制技术，以尽量减少无线信道中由传输误差引起的视频质量下降。本文简要介绍了无线视频传输的传输级误差控制技术的最新进展。此外，还将简要讨论最新移动电视和数字电视标准中实现的传输级错误控制技术。

Recent advances in transport level error control techniques for wireless video transmission

Transmission of compressed video over wireless channels remains a challenging task due to the noisy nature of the wireless channels and a single bit error in the compressed video bit-stream might cause the reconstructed video to be severely distorted. Numerous error control techniques have been proposed in the literature in order to minimize the video quality degradation caused by transmission errors in wireless channels. This paper provides a brief review of the recent advances in transport level error control techniques for wireless video transmission. In addition, the transport level error control techniques implemented in the latest mobile TV and digital TV standards will also be briefly discussed.
