"..convergence of the computing, communications and entertainment industries." For a nuts and bolts but readable summary of the "bandwidth issue" See webserver.cpg.com Pay particular attention to: "The telephone companies have put forth three solutions. Asymmetric Digital Subscriber Line (ADSL), their Band-Aid solution, is based on the use of already existing twisted-pair copper wire used for plain old telephone service. ADSL offers a T1 (1.536-Mb/s) connection plus an analog telephone channel. But, as we saw above, this basically supports, at most, MPEG-1. There are other implementations that support MPEG-2, though only over small local loops. Fiber to the Curb (FTTC) is another solution that can support full-duplex T1 or T2 (allowing for applications such as symmetrical videoconferencing). The third solution offered by the telephone companies is Fiber to the Home (FTTH), which can support a whopping OC-3 bandwidth of 150 Mb/s (or 100 T1 lines). The cable companies are offering a different solution. Hybrid Fiber Coax (HFC) is currently being installed. Basically, it replaces the 450-MHz coaxial cables with 750-MHz cables, resulting in 125 6-MHz channels, 75 of which are reserved for television. The other 50 channels each provide 40 Mb/s, thereby bringing a total additional bandwidth of 2 Gb/s into each home." Ed Perry
