program, the video bit-rate may exceed 10Mbps, even up to 15Mbps. However, the
maximum possible bit-rate output for single DVB-T carrier is only around 30Mbps.
15Mbps x4 =60Mbps > 30Mbps.
It means the single DVB-T carrier simply can't carry the 4 channels 1080i HD
programs if the average bit-rate reaches 15Mbps.
That's why we design 2*DVB-T carrier modulation board which double the maximum
possible bit-rate bandwidth up to 60Mbps, which rightly makes it reliably carry 4
channels HD programs output simultaneously.
Below brief chart will help to more clearly illustrate the working principle.
