IPC: H04N5/00
Filed: 1980-05-01
Abstract: PURPOSE:To prevent cross talk from deteriorating only by adding a simple circuit, by separating video and voice signals and inputting one or both signals to a phase shifter. CONSTITUTION:A TV signal entering from terminal IN is branched by hybrid HYB1 for signal distribution; one component has the voice carrier separated by band-elimination filter BEF for sound carrier elimination and is amplified by amplifier AMP, whose output is inputted to hybrid HYB2 for output signal composition. The other signal is supplied to voice carrier BPF to pass through only the vice carrier; and the output is set by limiter LIM to a prescribed level and adjusted by phase shifter P.H to a phase difference in which cross talk is not deteriorated. The output of phase shifter P.H is mixed with a video carrier by hybrid HYB2 for output signal composition to send the output from terminal OUT. Consequently, the cross talk from the main channel to sub channel is suppressed in voice multiplex broadcasting such as bilingual broadcasting.
