How many sets of digital TV programs can be transmitted by DMB-T system in each channel?
In fact, the content of the program determines the level of the code stream. We cannot simply say how many digital TV programs can be transmitted in each channel, but also depends on the specific program application, source compression technology and other factors.
Under normal circumstances, using the MPEG-2 compression standard to transmit a set of fast-moving sports programs probably requires 4 to
5Mbps bit stream, about 3Mbps bit stream is needed to transmit a set of news and interview programs, only 1.5Mbps bit stream is required to transmit a set of graphic information, and about 20Mbps bit stream is required to transmit high-definition TV programs. therefore,
It is necessary for the operating unit to arrange the number of programs reasonably. Refer to Table 3 for details.
