Abstract

In a video cassette recorder (VCR) adapted for use in conjunction with a television (TV) receiver, a audio signal generator is used to produce an audio signal in response to key closures made on the VCR'"'"'s remote unit with the TV speaker being used as an audio output device. In an alternative embodiment, the audio generator is in the form of a speech synthesizer which generates a human-voice message in response to commands entered via the keypad. The main VCR housing may alternatively come equipped with its own speaker, obviating the need to feed the audio signals to the TV.

Claims

1. A VCR providing audible feedback through an associated television receiver, comprising:

a remote control unit including a keypad operative to accept user commands and a transmitter operative to transmit control codes representative of said commands;

a housing separate from said remote unit, including;

a remote control receiver operative to receive control codes transmitted by the remote unit;

an audio signal generator;

an RF modulator having as an input the output of said audio signal generator, the modulator being operative to modulate the audio signal onto an RF channel output signal;

control means connected to the audio signal generator and the remote control receiver, said control means being operative to detect key closures on the remote keypad and cause the audio signal generator to generate an audio signal when a key is depressed; and

a connector disposed on said housing and cabling means to deliver said RF channel output signal to said television receiver so that said audio signal may be heard through said television receiver.

2. The VCR with audible feedback of claim 1 wherein the audio signal generated by said audio signal generator in response to a remote key closure is the same audio signal regardless of which key is depressed.

3. The VCR with audible feedback of claim 1 wherein the audio signal generated by said audio signal generator in response to a remote key closure varies in accordance with which key is depressed.

4. The VCR with audible feedback of claim 3 wherein said audio signal generator includes a speech synthesizer, and wherein said control means is operative to cause said synthesizer to generate a signal representative of a voice message relating to the command entered in accordance with key depressions on the remote unit.

5. The VCR with audible feedback of claim 4 wherein said control means is further operative to delay the generation of said voice message until detecting a plurality of key closures in order to interpret complex commands.

6. The VCR with audible feedback of claim 1 further including a non-modulated audio output and associated connector disposed on said housing to deliver said non-modulated output directly to said television receiver.

7. In a VCR with a remote control unit, the method of providing audible feedback through an associated TV in response to keypad depressions made on the VCR remote control unit, comprising the steps of:

transmitting to the VCR a signal related to a keypad depression made on its associated remote unit;

receiving said keypad-related signal at the VCR;

generating an audio signal in response no said keypad-related signal; and

outputting an audio signal to the TV by modulating said audio signal onto an RF carrier.

8. The method of claim 7 wherein the step of generating an audio signal in response to said received signal includes the step of synthesizing a human voice message relating to said keypad depression.
