DVB-T/T2对比
在几个主要的数字电视地面传输标准(DVB-T,ISDB-T,DTMB,DVB-T2)中，DVB-T2是最晚出现的，也是综合了各种最新技术的集大成者。
DVB-T2在8 MHz带宽内所支持的最高TS流传输速率约50.1 Mbit/s，如果算上它的删除空包机制，则更高。这显然远远高于DVB-T的31.67 Mbit/s的最高传输速率，DTMB的32.4864Mbit/s，以及ISDB-T的23.234Mbit/s(6M带宽)。
The following table reports a comparison of available modes in DVB-T and DVB-T2.[20]
