摘要

本文介绍了一种基于CATV(HFC)进行数字视频传输的方法.讨论了传输系统中编码分配器(CU)的实现方案.着重介绍了MPEG-2 TS发送卡的设计

包括发送卡的功能、电路结构、硬件设计和软件设计.给出了关键信号的实现及仿真结果和发送卡的工作状态转移过程.最后介绍了发送卡在一个实用系统中的使用情况.实际应用的结果表明发送卡工作性能稳定可靠

对MPEG-2传输流数据分路/发送获得了满意的效果.

Abstract

This paper introduces one method for digital video transmitting over CATV (HFC).We discussed the implementation of CU (Coding assigning Unit) applied in a transmission system.The design of the MPEG-2 TS Card is introduced

including its main functions

circuit configuration

hardware and software design.The implementation of the key signals and the result of its numerical simulation as well as the process of the state transition of the card are given.Finally

a practical system applying the card is described briefly.As a result that the card can work reliably and stably

to achieve satisfactory transmission of MPEG-2 TS.
