| 摘 要： | 介绍了一种基于MPEG-2语法结构对TS流进行无缝拼接的方法,它不需要进行模数转换,而直接基于MPEG-2语法结构进行拼接,是一种全数字式的拼接方法,避免了由模数、数模转换中引入的噪声影响.整个系统只用到了数字处理FPGA芯片,以及缓存FIFO两块主要芯片,电路简单,同时它还有很好的通用性和可扩展性.

| Abstract: | In this paper, how to perform TS seamless splicing based on MPEG-2 is analyzed in detail. Because it uses the syntax of MPEG-2 directly to splice v ideo stream, it is entirely in digital way. There are only two basic chips used in the whole system, and the system can be very small and simple. At the same ti me, it is very good for further expansion and multi-purpose use. |
