Apparatus and method for automatically performing channel change of television receiver using video cassette recorder
First Claim
1. An apparatus for automatically changing the channel of a television receiver using a video cassette recorder, comprising:
- video playback mode detection means for detecting a video playback mode;
channel sensing means for sensing a predetermined video viewable channel;
memory means for storing the video viewable channel sensed by said channel sensing means and television receiver channel change data;
control means, located in the video cassette recorder, for reading the television receiver channel change data stored in said memory means and generating a channel changeover command corresponding to the video viewable channel sensed by said channel sensing means to change a television receiver channel upon the detection of the video playback mode; and
data transmission means for remotely transmitting the channel changeover command from said control means to a remote control input port of the television receiver to cause the television receiver to change a current channel of the television receiver to the video viewable channel sensed by said channel sensing means in the video playback mode.

Abstract
An apparatus for automatically performing channel change of a television receiver using a video cassette recorder includes a playback command detector for detecting a playback command, a channel sensor for sensing a video viewable channel which is selected by a radio frequency changeover switch according to a user'"'"'s selection, a memory for storing the video viewable channel sensed by the channel sensor, television receiver channel change data and television receiver codes corresponding to different types of the television receiver, a controller for reading one of the television receiver channel change data stored in the memory corresponding to the video viewable channel sensed by the channel sensor upon the detection of the playback command by the playback command detector, and a remote transmitter for remotely transmitting the television receiver channel change data from the controller to the television receiver to change a current channel of the television receiver to the video viewable channel sensed by the channel sensor in a playback mode of the video cassette recorder. According to the invention, the current channel of the television receiver can automatically be changed to the video viewable channel upon input of a playback key signal or insertion of a video tape into a deck of the video cassette recorder.

16. A method of automatically performing channel change of a television receiver using a video cassette recorder, comprising the steps of:
-
sensing a predetermined video viewable channel; matching a type of the television receiver and a type of the video cassette recorder; storing the sensed video viewable channel; detecting a playback command; reading television receiver channel change data from memory means upon detection of the playback command; converting the read television receiver channel change data into a television receiver channel change code; and remotely transmitting the converted television receiver channel change code from the video cassette recorder to a remote control input port of the television receiver to change a current channel of the television receiver to the set video viewable channel.
