Abstract

A remote control transmitter, preferably a universal or reconfigurable remote control transmitter, is incorporated into a television receiver. Mounting a light emitting source such as a light emitting diode in a line of sight or a wired connection with an external tuning system such as that of a VCR or cable converter, and modification of the television tuning system to cause the transmission of activating signals to the remote control transmitter, allows functions which are channel associated and which are therefore generally suppressed when a remote tuning system is used to remain in force.

Claims

1. In a television receiver having a channel-associated function which is automatically executed when a television tuning system in the television receiver is selectively tuned to a selected channel, a function restorer for restoring said channel-associated function which is suppressed when said television tuning system is fixedly tuned to an available channel different from said selected channel and tunning of said television receiver is controlled by external tuning means, said function restorer comprising:

means for generating an external tuner selection signal and a first selected channel signal signifying said selected channel;

means responsive to said external tuner selection signal and said first selected channel signal for tuning said television tuning system to said available channel and executing said channel-associated function; and

remote control transmitter means in said television receiver and connected to said television tuning system for generating, in dependence on said channel-associated function, a second selected channel signal corresponding to said first selected channel signal and transmitting said second selected channel signal to said external turning means for tuning said external tuning means to said selected channel.

2. A function restorer as set forth in claim 1, wherein said external tuning means has receiver means for receiving said second selected channel signal;

and wherein said remote control transmitter means is mounted in a line of sight with said receiver means.

3. A function restorer as set forth in claim 1, wherein said remote control transmitter means is connected by a wire connected to said external tuning means.

4. A function restorer as set forth in claim 1, wherein said remote control transmitter means includes a light emitting diode.

5. A function restorer as set forth in claim 4, wherein said light emitting diode emits infrared signals.

6. A function restorer as set forth in claim 1, wherein said remote control transmitter means comprises a universal remote control transmitter means adapted to control a plurality of different types of devices.

7. Apparatus as set forth in claim 6 wherein said plurality of different types of devices comprises VCRs and cable converters.
