摘要

研究了一种提高数字视频广播(DMB)视频质量的标题语法修复方法。给出了基于MPEG-2传输流包的报头不同部分的传输错误对DMB视频质量影响的灵敏度分析。在此基础上，提出了一种使用报头掩码和有界最小距离解码的报头语法修复方法。客观和主观质量评价表明，标题语法修复后的DMB视频片段的质量有了巨大的提高。为DMB视频流的分组提出的报头语法修复方法的概念也可以适应于其他数字视频标准的分组格式的语法。

DMB Video Quality Enhancement Using Header Syntax Repair

This paper studies a header syntax repair approach for quality enhancement of digital video broadcasting (DMB) videos. A sensitivity analysis of the impact of transmission errors in different parts of the header of the underlying MPEG-2 transport stream packets on DMB video quality is provided. On this basis, a header syntax repair approach is presented using header masks and bounded minimum distance decoding of the headers of the received DMB packets. Objective and subjective quality assessment show a tremendous improvement in the quality of the header syntax repaired DMB video clips. The concepts of the header syntax repair approach proposed for packets of DMB video streams may also be adapted to the syntax of packet formats of other digital video standards.
