Transmission Scheme for ISDB-T System

数字电视地面传输标准ISDB-T系统传输方案

In addition , a brief comparison is also presented for the ISDB-T system and the DVB-T system since they both use OFDM modulation scheme .

同时，由于ISDB-T和DVB-T系统均采用OFDM调制技术，所以对两者进行了比较。

Using banding segmented transmission Orthogonal Frequency Division Multiplexing ( BST-OFDM ) Japanese NHK the ISDB-T standard .

采用频带分段传输正交频分复用（BST-OFDM）的日本NHKISDB-T标准。

DVB-T and ISDB-T are the multi-carrier transmission systems , They are easy to support the fixed receiving and the motion receiving .

DVB-T和ISDB-T为多载波传输系统，能较好的支持固定接收和移动接收。

Currently , this product has been in volume production , accept the orders which Japan , Brazil , Chile and other countries using the ISDB-T customer .

目前，本产品已处于量产阶段，接受日本、巴西、智利等使用ISDB-T国家的客户订单。

Then the paper illustrated the system structure of ISDB-T and DVB-T in detail , and analyzed the key technologies in signal-channel encoding of the two systems .

接着本文先分别详细介绍了ISDB-T和DVB-T的系统架构，然后在此基础上分别对两种制式的信道编解码关键技术进行分析。

DVB-T , ISDB-T and ATSC are the hard cores of DTT technology . And contract testing , details of practical application and technical foreground of the three systems are analyzed .

分析这些技术的核心部分，DVB-T、ISDB-T、ATSC3种系统的对比测试、实际运用的细节以及技术发展的方向和前景。

Now , it has three digital terrestrial TV standards that have come into the practical stage , namely : DVB-T in Europe , ATSC in the United States and ISDB-T in Japan .

目前世界上已经提出了三个数字地面电视标准，分别为：欧洲的DVB-T，美国的ATSC和日本的ISDB-T，且都达到实用阶段。

ISDB-T is the Japanese digital TV terrestrial broadcasting transmission standard , having made the part improvement to DVB-T , not only supporting fixed receiving and the motion receiving well , but also supporting the synthesis service data broadcasting in a certain extent .

ISDB-T为日本地面数字广播传输标准，对DVB-T做了部分改进，不仅能较好的支持固定接收和移动接收，在一定程度上也能支持综合业务数据广播。

At this stage , there are four kinds of major international terrestrial digital TV transmission standard : ATSC ( U.S.A ), DVB-T ( European ), ISDB-T ( Japan ) and Chinese Digital Television Terrestrial Transmission Standard ( for short : DMB_TH ) .

现阶段国际上主要有四种数字电视地面传输标准：美国的ATSC，欧洲的DVB-T，日本的IDSB-T以及中国的DMB-TH。
