Abstract

A commercial message timer, when enabled by a user, stores data indicative of a first tuned station and begins timing a predetermined time period. Upon expiration of the time period, the first tuned station is automatically reselected if it had been deselected after the timer was enabled. In this way a user can avoid a commercial message on a first channel by setting the timer and scanning through other channels, and yet have the receiver return automatically to the first channel at the end of a time period substantially equal to that of a typical commercial message. In another embodiment employing PIX-IN-PIX circuitry, the subject apparatus is responsive to the sequence of (1) enabling the timer and (2) changing channels for automatically moving the desired channel to the insert position. In response to the expiration of the timer period, the program displayed in the insert position is automatically returned to the main display position.

Claims

1. A signal selection system, comprising:

selecting means for selecting, in response to a selection signal, a particular signal from a plurality of signals which may be presented thereto;

control means coupled to said selecting means for generating said selection signal for controlling the selection of said particular signal from said plurality of signals;

said control means having an input for receiving a timer start signal;

said control means including timer means responsive to said timer start signal for timing a predetermined time period; and

memory means coupled to said control means for storing, in response to said timer start signal, data relating to the selection of said particular signal;

said control means generating said selection signal for selecting said particular signal in accordance with said stored data upon expiration of said predetermined time period if a different one of said plurality of signals were selected after the occurance of said timer start signal and during said predetermined time period.

2. Apparatus for use in a radio frequency (RF) signal receiver, comprising:

data input means for generating data in response to activation by a user;

control means coupled to said data input means for generating a tuning control signal in response to said data received from said data input means;

tuning means responsive to said tuning control signal for selecting an RF signal from a plurality of RF signals applied thereto;

memory means coupled to said control means for storing data relating to said tuning control signal;

timing means coupled to said control means for timing a predetermined period;

said control means in response to data from said data input means causes said memory means to store channel data indicative of a first tuned channel, and causes said timing means to begin timing said predetermined time period, and, upon expiration of said predetermined time period said control means causes said tuning means to tune said first tuned channel in accordance with said stored channel data, if said tuning means were tuned to a different channel during said predetermined time period.

3. The apparatus of claim 2 wherein said control means in a microcomputer.

4. The apparatus of claim 3 further including means coupled to said control means for producing a signal indicative of the time remaining in said predetermined time period.

5. The apparatus of claim 2, wherein said predetermined timing period is changed in response to said data input by a user.

6. Apparatus for use in a television system, comprising:

control means for generating a video signal selection control signal in response to data;

data input means coupled to said control means for generating said data in response to activation by a user;

video signal selection means including tuning means responsive to said video signal selection control signal for selecting a television channel from a plurality of RF signals corresponding to respective television channels applied thereto;

memory means coupled to said control means for storing data relating to said video signal selection control signal;

timing means coupled to said control means for timing a predetermined time period;

said control means causes said memory means to store video signal selection data indicative of the currently selected video signal, and causes said timing means to begin timing said predetermined time period, and, upon expiration of said predetermined time period, said control means causes said video signal selection means to reselect said selected video signal in accordance with said stored video signal selection data, if said video signal selection means were controlled to select a different video signal during said predetermined time period.

7. The apparatus of claim 6 wherein said control means is a microcomputer.

8. The apparatus of claim 7 further including means coupled to said control means for producing a signal indicative of the time remaining in said predetermined time period.

9. The apparatus of claim 8 wherein said predetermined time period is changed in response to said data input by a user.

10. The apparatus of claim 9, wherein said video signal selection means further includes a video multiplexer switch unit for selecting a baseband video signal which may be provided by a baseband video signal source, and said video signal selection data includes the state of said video multiplexer switch unit.

11. The apparatus of claim 9 wherein said television system further includes means for combining first and second video signals from respective independent sources to produce first and second combined signals, said first combined signal producing when displayed a combined image having a first portion corresponding to said first video signal displayed in a first area of a display screen and a second portion corresponding to said second video signal displayed in a second area of said display screen;

said control means causing said memory means to store in response to a timer start signal, data indicative of a particular signal to be displayed in said first area of said display screen;

said control means being responsive to an occurrence of said timer start signal and the selection of a third signal in that order for causing said combining means to produce said second combined signal wherein said first portion of said image occupies said second screen area when displayed;

said control means causing said combining means to produce said first combined signal wherein said first portion of said image occupies said first screen area when displayed, in response to the expiration of said predetermined timer period if said first signal had occupied said second screen area after said timer start signal occurred and during said predetermined time period.

12. The apparatus of claim 11 wherein upon expiration of said time period said first signal is caused to occupy the entirety of said display screen.

13. The apparatus of claim 10 wherein said television system further includes means for combining first and second video signals from respective independent sources to produce first and second combined signals, said first combined signal producing when displayed a combined image having a first portion corresponding to said first video signal displayed in a first area of a display screen and a second portion corresponding to said second video signal displayed in a second area of said display screen;

said control means cuasing said memory means to store, in response to a timer start signal, data indicative of a particular signal to be displayed in said first area of said display screen;

said control means being responsive to an occurrence of said timer start signal and the selection of a third signal in that order for causing said combining means to produce said second combined signal wherein said first portion of said image occupies said second screen area when displayed;

said control means causing said combining means to produce said first combined signal wherein said first portion of said image occupies said first screen area when displayed, in response to the expiration of said predetermined time period if said first signal had occupied said second screen area after said timer start signal occurred and during said predetermined time period.

14. The apparatus of claim 13 wherein upon expiration of said time period said first signal is caused to occupy the entirety of said display screen.
