1. In a wireless remote control system for a television receiver having a channel command device and a responding device;
- and in which said channel command device includes channel selecting means for selecing one channel command from among a plurality of predetermined channel commands, command signal generating means for generating a channel command signal corresponding to said one channel command and channel command transmitting means having a first transducer for transmitting said channel command signal; and
said responding device includes channel command receiving means having a second transducer for receiving said transmitted channel command signal and channel command discriminating means for discriminating said channel command signal and supplying a channel selecting signal corresponding to said discriminated channel command signal to a tuning circuit;
the improvement comprising;
return signal generating means located in said responding device for producing a return signal corresponding to the channel command indicated by said channel selecting signal;
return signal transmitting means also located in said responding device and having a third transducer for transmitting said return signal;
return signal receiving means located in said command device and having a fourth transducer for receiving the transmitted return signal;
return signal discriminating means located in said command device for discriminating said return signal and producing a discriminated return signal indicating the channel command to which said return signal corresponds;
comparing means located in said command device for comparing said one channel command and said discriminated return signal; and
indicating means connected to said comparing means for indicating a coincidence of said one channel command and said discriminated return signal.

Abstract
A remote control apparatus having a commander and a receiver. In a wireless remote control system for a television receiver having a channel command device and a responding device, the channel command device includes a channel selecting circuit for selecting one channel command from among a plurality of predetermined channel commands, a command signal generating circuit for generating a channel command signal corresponding to a selected channel command, and a channel command transmitting circuit having a speaker for transmitting the channel command signal; and the responding device includes a channel command receiving circuit having a microphone for receiving the transmitted channel command signal and a channel command discriminating circuit for discriminating the channel command signal and supplying a channel selecting signal corresponding to the discriminated channel command signal to control a tuning circuit of the television receiver. Further, there is provided in the responding device, a return signal generating circuit for producing a return signal corresponding to the channel command indicated by the channel selecting signal and a return signal transmitting circuit having a speaker for transmitting the return signal, while the channel command device further has a return signal receiving circuit having a microphone for receiving the transmitted return signal, a return signal discriminating circuit for discriminating the return signal and producing a discriminated return signal indicating the channel command to which the return signal corresponds, a comparing circuit for comparing the originally selected channel command and the discriminated return signal, and an indicating circuit connected to the comparing circuit for indicating a coincidence of the originally selected channel command and the discriminated return signal.
