摘要

对任意可编程但固定速率的视频电话编解码器进行了比较研究,该编解码器使用四分之一通用中间格式(QCIF)视频序列以10帧/秒的速度扫描。这些编解码器的设计目的是允许直接替换第二代无线系统中的移动无线电语音编解码器,如泛欧GSM、美国的IS-54和IS-95以及日本的系统,它们分别以13、8、9.6和6.7 kbps的速度运行。

Fixed-rate video codecs for wireless systems
A comparative study of arbitrarily programmable, but fixed-rate videophone codecs using quarter common intermediate format (QCIF) video sequences scanned at 10 frames/s is offered. These codecs were designed to allow direct replacement of mobile radio voice codecs in second generation wireless systems, such as the Pan-European GSM, the American IS-54 and IS-95 as well as the Japanese systems, operating at 13, 8, 9.6 and 6.7 kbps, respectively.
