摘　　要：针对两个不同数字HDTV TS节目流播放切换时产生短暂的黑屏进行研究。提出了调整第二个数字HDTV TS节目流解码、显示时间,使它解码、显示时间同第一个节目流解码、显示时间连续;调整拼接点处ES流码率,防止EB1缓冲区下溢两种方法来实现两个不同数字HDTV TS流的无缝拼接,除去了两个流一起播放时产生的黑屏现象。This paper researched the short-lived black screen between the two HDTV TS program stream during switching from one to another. Two methods of adjusting the second TS program stream decoding time and presentation time and adjusting the bit rate of ES near the spicing point to prevent the EB1 buffer from underflow was proposed to realize the seamless splicing, finally get rid of black screen during playing the two program stream together.

关 键 词：无缝拼接 TS流 码率调整 HDTV
