发明名称 PAY-PER-VIEW PROGRAM ACCESS CONTROL SYSTEM
摘要 A pay-per-view program access control system which combines a television signal (52) with a telephone control signal (58) to allow a remotely located telephone connection to be coupled to a television receiver via a single wire or transmission line (59). The television signal is combined with the telephone control signal and the combined signals are then separated at a remote location by a splitter (66). Once separated, the television signal (202) and telephone control signal (206) can be used as if they had been transmitted to the remote location separately. The single transmission line also carries one or more pilot tones with or without modulated data to select one of a plurality of transmission signals to couple to the television receiver via a multisswitch.
