Delivery of TV over Existing Phone Lines
A system for delivering compressed digital TV over existing phone lines concurrent with conventional phone service is described. — The system uses MPEG (Motion Picture Experts Group) compression and an innovative transmission technique, called Carrierless Amplitude Modulation (CAP). Some of the details of these technologies and how they are used in the system are covered. MPEG1 is an approved standard and is soon to be followed by MPEG2. — Some phone companies are seriously considering the use of such a system. Their interest was spurred by the FCC's Video Dialtone Order adopted July 16, 1992. One of the FCC-approved video dialtone trials, which began in mid-1993, uses the system.
