场视频信号编码器的性能分析

ENCODE PERFORMANCE ANALYSIS OF INTERLACING VIDEO SIGNAL

为了不断地提高压缩性能,ITU和ISO组织推出了H.26x和MPEG-x系列标准.由于场视频信号在显示时存在的场效应问题,系列标准中只有3个标准给出了场视频信号的编码方法,分为帧/场固定和帧/场自适应两大类.通过测试给出了这两类方法对场视频信号的编码性能比较,并给出了影响场视频信号编码性能的主要因素.

In order to improve compression performance, H. 26x and MPEG-x series standards are given by ITU and ISO. Due to field display problem, only three standards support field video signal cod- ing, and they are grouped into two categories, fixed frame/field mode and Adaptive frame/field mode. In this paper, the coding performance of the two modes is tested and main issues for interlacing video signal coding is given.
