日本数字电视首先考虑的是卫星信道,采用QPSK调制.并在1999年发布了数字电视的标准--ISDB.ISDB是日本的DIBEG(Digital Broadcasting Experts Group 数字广播专家组)制订的数字广播系统标准,它利用一种已经标准化的复用方案在一个普通的传输信道上发送各种不同种类的信号,同时已经复用的信号也可以通过各种不同的传输信道发送出去.ISDB具有柔软性,扩展性,共通性等特点,可以灵活地集成和发送多节目的电视和其它数据业务.

除了ISDB-Tmm以外,多媒体广播采用的其它标准包括ISDB-Tsb和MediaFLO。在广播机构申请许可证时,他们将选择其中一种标准。ISDB-Tmm通过组合一些13段(5.6MHz)组和若干1段格式(1段=0.4MHz),无需保护频带,并能用于各种频带。已经开发了针对一个33段组合的发射机,传输成本大幅降低。ISDB-Tmm的多功能性使之适用于广泛的工作频带,以及支持7MHz和8MHz频带的频谱分配。此外,ISDB-Tmm与地面数字电视系统高度兼容,允许接收机共享及降低传输成本。因此,ISDB-Tmm被视为已经采纳ISDB-T为地面数字电视系统标准的国家的理想多媒体广播系统。
据国外媒体报道,厄瓜多尔已宣布采用日本-巴西数字电视标准,参与竞标的中国标准在走出国门的第一站惜败。以普天为首的中国标准团队曾一度志在必得,并于去年在国内进行了高调宣传。此前,拉美地区有12个国家尚未确定数字电视国家标准;而拉美国家本身一直在提倡一体化,如果在一个国家推广成功了,那其它国家很可能会受影响,对中国数字电视标准进军拉美会有非常大的帮助。中国参与竞争的标准是数字电视国标DTMB,曾用于在2008年北京奥运会播出奥运体育节目。日本-巴西数字电视标准ISDB-T胜出经多国竞争后,厄瓜多尔决定采用日本-巴西数字电视制式标准,制式标准合作备忘录于26日签订。日本ISDB-T采用的地面传输制式
数字固定及移动电视芯片市场领先厂商法国迪康公司,日前发布两款最新的调谐-解调片上系统(SoC)方案。这两款芯片分别支持DVB-T及ISDB-Tfull-seg标准,为便携和固定接收装置提供高性能数字电视技术,并可以极低的成本集成到机顶盒、电视机及PCTV中。随着模拟电视在欧洲的逐步关闭,DVB-T接收器维持着持续的高需求。南美和俄罗斯不久前也正式开始运营ISDB-T和DVB-T数字地面电视。这种大规模需求的趋势也将在未来几年进一步延续。DIB7090P和DIB8096P这两款SoC芯片引脚完全兼容,都是64引脚,9x9mmQFN封装,专为发展迅速的全球市场而设计。在过去四年里,迪康在全球部署了
2003年底,日本开始运营ISDB—T。截止2010年6月地面数字电视接收机达到7300万台,预计2010年9月覆盖率将达到91%。2010年2月,手持电视的数量达到7800万台。日本是世界上地面数字电视普及最快的国家之一。据最新报导,南美地区的巴西、阿根廷、智利等国采用了ISDB—T制式,受此影响,先前选用DVB—T的南非也准备改选ISDB—T。目前,世界上有四种独立的地面数字电视制式:(1)美国的ATSC;(2)欧洲的DVB—T;(3)日本的ISDB—T;(4)中国的地面数字电视广播标准。在南美市场的激烈竞争中,ISDB—T取得了成功,为什么ISDB—T会在南美地区取得成功,究其原因主要是
