One of the thorniest questions faced by all access providers is how much bandwidth will be required to support high definition and other forms of TV. Operationally, the discussion tends to turn on how many simultaneous HDTV streams might be required. The thinking in some quarters is that only a single HDTV stream and one or two standard definition streams will have to be supported concurrently.
SureWest Communications is planning to support multistream high definition DVRs and that will require additional bandwidth, says Bill DeMuth, SureWest Communications CTO. "We are already experiencing about 1.5 HD TVs per home so that is two streams, and if you want to watch one and record two streams it can easily lead to three to four streams of HD being delivered at the same time.
