两年以前,关于Bell Atlantic的视频拨号音频实验工作正在进行。在研究这个项目中,注定大多数MPEG服务机构每月处理的材料是有限的几十分钟。如果挤时间多做,编码质量开始变坏。正因为此,Bell Atlantic创立TELE-TV系统数字服务机构(DSB),来满足所有编码的需要。由于使用模块化设备体系结构,使现在设备能对大量视频数据编码,而没有其它设施的时间与质量折衷的问题。本文将详细介绍MPEG编码过程的不
Two years ago, experimental work on video-dialing audio at Bell Atlantic was in progress. In researching this project, the material most destined for most MPEG service agencies is limited to tens of minutes. If you squeeze more time, the quality of the code starts to deteriorate. Because of this, Bell Atlantic founded the TELE-TV System Digital Service (DSB) to meet all coding needs. Thanks to the modular device architecture, today’s devices can encode large amounts of video data without compromising the time and quality of other facilities. This article will detail the MPEG encoding process is not
