Firstly, it is to guarantee the sound picture quality of HD programs.

As we all know, to guarantee the picture quality of 1920x1080@50I/60I resolution HD 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 x4channel =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.

Secondly, it is cost-saving.

Its high integration allows users to transmit more programs with fewer devices. It undoubtedly saves the cost for you and me.
