摘要
本文介绍了DVB-C标准下传输流的复用/解复用原理,提出了利用软件对传输流解复用及服务信息解析的解决方案,并通过STM320DM8168芯片实现了灵活、高效的软件解复用系统。整个解复用系统主要包括了PID过滤、PSI解析和SI解析三部分。
In the paper, the theory of transport stream multiplexer/de-multiplexer based on DVB-C system is introduced.A solution that depends on software is proposed to accomplish transport stream demultiplexing and service information analysis, which implements a flexible and efficient demultiplexing system with STM320MD8168.The whole demultiplexing system is divided into three parts：PID fil- tering,PSI analysis and SI analysis.
