Description
Television receiver remote control system with television audio
This invention relates to hand-held television receiver (TV) remote controls, and in particular, to a TV remote control system with TV audio that includes a hand-held remote control with conventional TV and video recording device functions, and an audio receiver and speaker arrangement that permits the audio signal portion of a secondary channel to be listened to without disturbing the audio and video of a primary channel tuned on an associated TV.
In the past, TVs permitted only a single television channel to be viewed and listened to at a time. However, many TVs are now equipped with picture in a picture systems (PEP) which permit simultaneous viewing of two or more television channels.
Most of these PIP equipped TV designs permit the audio of just one of the television channels to be listened to at a time. There are some PIP equipped TV designs that will permit the audio of two or more television channels to be simultaneously listened to through the speakers of the TV. Unfortunately, the different audio programs generated from the speakers of the same TV at the same time interfere with one another and make listening to either very difficult.
Accordingly, a system is needed which permits the audio of a secondary channel to be listened to without disturbing the audio and video of a primary channel tuned on an associated TV.
A television receiver remote control system comprising a receiver for receiving audio signal portions of signals carrying television channels, an audio transmitter for transmitting the audio signal portion of a selected one of the channels received by the receiver, and a remote control for remote operation of the receiver to select the audio signal portion of a desired channel for transmission by the transmitter, and for remote operation of a TV. The remote control includes an audio receiver for wireless receipt of the audio signal portion of the selected channel transmitted by the transmitter, and an audio speaker or
headset connection for converting the received audio signal portion into sound. The system may permit the audio signal portion of any selected channel to be listened to with the remote control via the speaker without changing a channel selected on an associated TV.

The remote control 12 is also provided with an audio function keypad 28 and associated electrical circuitry 30 for operating the TV audio receiver/transmitter base unit via the infrared transmitter 18. The audio keypad 28 typically provides volume control functions 32 for the audio generated by the remote control 12, a 3-way switch 34 for selecting among a television, a video cassette recorder, and the remote control audio, and power buttons 36 for all three functions (TV, VCR, and audio). The remote control 12 can be further provided with an earphone jack 38 for using standard headsets 39 and a rechargeable battery pack (not shown).
As shown in FIGS. 3A and 3B, the TV audio receiver/transmitter base unit 14 includes known components and circuitry 40 for receiving wireless and cable television signals carrying UHF and VHF channels, for tuning and selecting a particular one of these channels via the remote control, and for transmitting the audio signal portion of a selected channel to the remote control. An antenna 42 is provided for receiving wireless television signals and transmitting the audio signal portion of a selected channel to the remote control 12. A coaxial cable connection 44 is also provided for connecting the base unit 14 to a coaxial cable (not shown) that carries television signals.
The TV audio receiver/transmitter base unit 14 further includes an A/C power cord connection 46 for electrically connecting the base unit into a standard electrical outlet, and an infrared remote sensor 48 for receiving infrared control signals from the remote control 12 that permit channel selection and power the base unit 14 on and off. Integrated into the base unit 14 is a charging station 50 (Fig. 1) for holding the remote control 12 when not in use and recharging its battery pack. The charging station 50 includes an A/C to D/C power supply 52 and known battery charge control circuits 54. A channel display 56 can also be provided for displaying channels selected by the remote control.
The TV remote control system 10 of the invention advantageously allows a user to listen to the audio of a selected television channel from any location within the transmitting range of the TV audio receiver/transmitter base unit 14 using the hand-held remote control 12. The system 10 also allows a user to listen to the audio of a secondary television channel (or audio surf from channel to channel) via the remote control 12 and base unit 14 without disrupting the audio and video of a primary channel selected on an associated
TV. Accordingly, the use of the system 10 with a television receiver containing a PIP system (not shown) brings audio to the secondary picture.
FIG. 4A shows a TV remote control system 60 with TV audio according to a second embodiment of the invention. This embodiment of the system 60 combines the remote control 12 of the first embodiment with a video recording device such as a conventional video cassette recorder (VCR) 62, modified with a conventional audio transmitter unit 64 that transmits the audio signal portion of a channel selected on the VCR 62 to the audio receiver 24 (Fig. 2) of the remote control 12. A free standing charging station 66 can be provided for holding the remote control 12 when not in use and recharging its rechargeable battery pack.
