These streams are called sub-channels.
这些码流就被称为子频道。
For example, if the digital TV channel is channel 53, then 53.1, 53.2 and 53.3 could be three sub-channels on that channel.
对于数字频道53来说，53.1，53.2，53.3就是它的三个子频道。
However, in far-end crosstalk, its sub-channels exist still a lot of frequency spectrum overlapping and increase error-rate.
在远端串扰时，其各子信道仍然存在着较大的频谱重叠，使误码率增加。
Some parameters such as the depth of interleaving and selection of sub-channels can be planned depending on the reality to achieve the optimization.
上述为方案的大体流程，其中具体实现参数，比如交织深度、基准信号对应的信道的选取等一些参数要依具体应用而定，使系统性能达到最佳。
Each broadcaster has one digital TV channel, but one channel can carry multiple sub-channels if the broadcaster chooses that option. Here's how it works.
每个广播商有一个数字频道，但只要广播商愿意，每个频道能携带多个子频道(sub - channel)。
The reason that broadcasters can create sub-channels is because digital TV standards allow several different formats. Broadcasters can choose between three formats.
广播商可以创建子频道的原因是数字电视标准支持不同的格式。
It is very likely that broadcasters will send three or four sub-channels during the day and then switch to a single high-quality show that consumes the entire 19.39 Mbps at night.
广播商很可能白天同时传送3到4个节目而晚上利用所有带宽播出高品质的电视节目。
