Here in KC, TimeWarner Cable now has Movies On-Demand, about 50 or 60 different movies available whenever you want to watch them. In addition, they have Comedy Central On-Demand (8 30-minute episodes of various shows and several 2-3 minute long clips from South Park, etc.), Showtime On-Demand, Cinemax On-Demand, HBO On-Demand, Food Network On-Demand, Cartoon Network On-Demand, and many others, in addition to 150 or more regular channels and 20 or 30 music channels. And they offer cable modem access through AOL Highspeed, RoadRunner, and I believe one other service. How does this fit in with the scenario above?The difference is that cable tv sends the same data to everyone, i.e., the backbones only need to carry one copy of the data which is virtually the same for all subscribers.With Internet, everyone is sending and receiving different data. If everyone wanted to watch a different movie simultaneously, there would not be enough bandwidth (a television program or movie takes about 6MHz of bandwidth). Most cable distribution systems have a total bandwidth of less than 1000MHz (some only have about 500MHz). This is primarily used up by 50 to 150 or so channels, depending on the system. There are only a few MHz left for cable modems, which typically share one 6MHz channel (which is good for 30 to 40Mb/s).
