摘要
近年来，随着多媒体的发展，ＣＤ－ＲＯＭ和各种交互式节目的普及，数据压缩越来越引起人们的关注。目前，ＭＰＥＧ－１已成为各种ＣＤ制作、远程实时视音频传输、信息高速公路等的核心技术。本文详细介绍了我们开发的以ＤＥＣ公司的ＭＰＥＧ编解码芯片Ｄｉｇｉｔａｌ２１２１３０为核心的实时ＭＰＥＧ１压缩卡。
In recent years,with the development of the multimedia technology and the popularization of CD ROM and various interaction programs,the data compression technique is attracting more and more attention.At present,MPEG 1 has become a crucial technique used in the remote real time audio video transfer,the information highway and the making of CDs.This paper describes in detail how to use a kind of MPEG codec chip Digital 21230 as a kernel component to make a real time compression card.
