CONSTITUTION:In the TV program signal generating device S of a TV station side, a broadcast signal transmitter S4 receives a teletext signal G1, a picture signal G2 and a sound signal G3 transmitted from a teletext signal transmitter S1, a picture signal transmitter S2 and a sound signal transmitter S3, and transmits a broadcast signal G4. The code for a program ID signal is provided in this signal G1, and program ID information is transmitted by being added to this code. Besides, the tuner R1 of a program signal receiving video control device R receives the broadcast signal G4, and the broadcast signal G4 is separated by the tuner R1 into the signal G3 and the picture and teletext signal B2, and the signal G3 is received by an amplifier R2, and is amplified by the amplifier R2, and is transmitted to a video device. Besides, the signal B2 transmitted to a picture signal and teletext signal separating device R3 is separated into the picture signal G2 and the teletext signal G1, and both are processed respectively.</p> |
