基于FPGA的MPEG-2复用器中FIFO的一种设计方案

多路节目复用器是各种数字电视传输系统的关键设备之一,自行设计复用系统专用芯片己成为我国数字电视系统需要解决的迫切问题。首先介绍了多路数字节目复用器中的对多路预处理传送流复用的原理,提出了一套基于FPGA(现场可编程门阵列)的复用器输入部分设计方案。通过实践验证,达到了设计要求。

A Design Scheme of MPEG-2 Multiplexer FIFO Based on FPGA

Broadcasting data and user data multiplexer have become one of the key equipments worked in the digital television transfer system. It has become the key problem for the home digital television system to produce dedication multiplexer chips independently. This paper introduces the multi-program multiplexing theory based on pre-processing Transport Stream(TS),and provides a design scheme of multiplexer FIFO based on FPGA. The experimental verification result shows that the design has achieved requirement.
