This system all signal dissemination is through the digital class which constitutes by 0,1 numstrings disseminates, digital signal's propagation speed is each second 19.39 megabytes, the so big data stream's transmission had guaranteed digital television's high definition, has overcome analog television's being congenitally deficient. Simultaneously because also the digital television may permit several kind of service pattern signals at the same time existence, under each digital channel and may divide into several sub-channels, thus both may use a big data stream - - each second 19.39 megabyte, may also divide into it several divergences, for example 4, each speed is each second 4.85 megabytes, although like the image clarity must sell at a discount greatly, actually may increase information greatly the type, meets the different need. For example when retransmits an athletic contest, the audience needs the high definition the image, the television station should use each second 19.39 megabyte dissemination; But when carries on the news broadcast, what the audience pays attention is the news content, but is not radio announcer's image, therefore the necessity has not used that high clarity, by now only needed each second 3 megabyte speeds to be possible, is left over 16.39 megabytes to be possible to use for to transmit other content.
