The reason to modulate the signal is so that cable, satellite, DVD, VCR etc can be monitored in multi-room A/V installtion at different channels at the same time. Without modulation, it would be difficult to switch from satellite to cable TV without having to switch off the satellite receiver. Remember, there is only one RF (RG-6) wire running to each TV from the central location in the basement.
