Abstract

The present invention relates to a reservation switching device for a television audio signal, the configuration of which selects and switches an output path of a broadcast audio signal provided to a viewer through a speaker (SP) of the television to the call signal processing unit 42 of the telephone 40. A voice switching means 24, a voice signal detecting means 26 for detecting a voice signal output from the voice signal processing means 16, a reserved input of a voice disease start and end time, a channel and a calling telephone number. Key input means (28) having a function key for controlling, control means (30) for performing control for reservation switching of a television sound signal in accordance with a key input signal through said key input means (28), and said control means Reservation data storage means (32) for storing the data for the start and end time of the voice change start and end time and the channel and the calling telephone number through the key input means (28) according to the control signal of (30). To supply power to each circuit of the television in accordance with a control signal of the control means 30 and a timer means 34 for continuously presenting the corrected current time data to the control means. Call control means for calling the other party according to the control signal of the power supply means 36, the control means 30, detects the call signal at the end of the call and provides the call detection signal to the control means 30. 938 and the control based on the output signal from the voice signal detection means 26 and the time signal TS and the call signal CS provided from the timer means 34 and the call control means 38. And a logical path means (39) for generating a signal for selecting and switching the output path of the sound switching means (24) by logically multiplying the control signals (TS, CS) by the means. It is effective to allow television, such as important news, to be heard through the telephone in an unconventional place.
