" 试论数字机顶盒的利弊和发展
[摘要] 随着微电子技术，计算机技术，光通信技术的飞速发展，特别是视音频编码技术的不断发展，引起了一场消费电子产品从模拟技术转向数字技术的革命。但无论是卫星数字直播电视，数字有线电视还是网络电视，都不能直接被用户使用的模拟电视所接收，因此需要一种接收装置来担当模拟和数字之间的桥梁，数字机顶盒也就应运而生了。数字电视机顶盒是信息家电之一, 它是一种能够让用户在现有模拟电视上, 观看数字电视节目, 进行交互式数字化娱乐、教育和商业化活动的消费电子产品。
本文就是在这种背景下，通过简要介绍数字机顶盒的基础知识，分析数字机顶盒的结构及关键技术，由此来研究数字机顶盒的利弊，并根据当前的形式来探讨数字机顶盒的发展。"

[Summary] along with the micro-electronics technique, calculator technique, only correspond by letter to technically fly to soon develop, especially see the audio frequency coding technically and continuously develops and caused 1 to consume an electronics product from imitate a technique to change direction numerical technical revolution.But regardless is the satellite numerical live television, numerical cabled T.V. be still a network television, can't be directly use by the customer of imitate a television receive, so need a kind of bridge of which receives to equip to take emulation and numeral, the numerical machine crest box also emerged with the tide of the times.The numerical television crest box is one of the information appliances, it is 1 kind and can let customer at existing imitate a television up, watch numerical television program, carry on the consumption electr
