摘要
本文提出了一种基于UDP协议的码流分析与检测的方法。通过抓包方式,在FM-CDR广播系统的复用器和发射机激励器之间捕获一段UDP协议报文数据,按照数据传输接口协议和FM-CDR数据包帧格式,从不同级别和层次对捕获的码流进行解析,并通过实例验证了对码流的完整性和一致性的检测,从而达到码流质量检测目的。
This paper presents a method of code stream analysis and detection based on UDP protocol. Through capturing packet, a piece of UDP protocol message data is captured between multiplexer and transmitter exciter of FM-CDR broadcasting system. According to data transmission interface protocol and FM-CDR packet frame format, captured code stream is analyzed from different levels and levels, and integrity and consistency detection of code stream is verified by examples, so as to achieve the purpose of code stream quality detection.
