Re: Great interview with insight to the near futur

This ignores 'switched video' currently being tested by some MSO's. It should reduce the bandwidth requirements of the cable plant or network - also known as the hybrid fiber coax or HFC.

How much bandwidth is required for cable companies to transmit their cable channels
It depends on how the network is setup. You have to know whether the system is 450Mhz, 550mhz, 750mhz, or 860mhz. Then you need to find out how many are analog and how many are digital, and whether they are 64QAM digital channels or 256QAM channels. Then crunch the numbers. Last time I played around with some numbers a full 860mhz system could have 5Gbps total capacity pushing though the network at any given time.
