TS流劣化软件的设计与实现

Design and Implementation of Transport Stream Degradation Software

为了研究数字电视码流在传输过程中的各种异常在TR101-290一级错误参数上的体现和画面影响,本文设计并实现一个可以编辑和输出劣化码流的软件。用以了解码流错误对终端播出音视频的影响;此外,可控的劣化码流对信号源码流检测阈值的设置、码流监测分析设备的测试都有很大的帮助。

In order to study 1 st level parameters in TR101-290 standard and image quality which are influenced by various anomalies during digital television transport stream transmission,this paper designs and develops a software that can edit and output degraded transport stream.It is used to analyze the effects of stream errors on audio and video of television terminal.In addition,controllable degraded transport stream greatly helps to set detection threshold of signal source stream and test stream monitoring and analysis equipment.
