Telephone service providers are now offering ADSL service to home using the existing twisted-pair telephone wires. The signal can be carried up to a maximum of 1-MHz baseband with an S/N (signal power/noise power in ratio) of 30 dB. S/N in decibels (dB) is defined as 10 log10(signal power/noise power). Using MPEG-2 compression techniques, (a) a non-sports video channel can be broadcast at 3-Mbps data rate and (b) a sports video channel at 6 Mbps. Shannon
