Abstract

A primary broadcast receiver is automatically tuned by a secondary broadcast receiver receiving a first broadcast signal corresponding to a source of an origin program by program transition detectors detecting monochrome interprogram dead frame or closed captioning for the hearing impaired text words according to user-specified tune conditions; by a tuner controller enabling the secondary broadcast receiver and a program transition detector to begin monitoring a first broadcast signal currently tuned by the primary broadcast receiver, while allowing tuning of the primary broadcast receiver by a user, and by automatically tuning the primary broadcast receiver to the first broadcast signal upon signal by the program transition detector that one or more of the user-specific tune conditions have been met.

Claims

1. A system for automatically tuning a primary broadcast receiver comprising:

a secondary broadcast receiver configured to receive a first broadcast signal corresponding to a source of an origin program;

one or more program transition detectors selected from a group comprising a monochrome interprogram dead frame detector and a closed captioning for the hearing impaired text word detector;

a set of user-specified tune conditions selected from a group comprising an enable selector for interprogram monochrome dead frames and one or more words for a closed captioning for the hearing impaired text word detector; and

a tuner controller configured to, upon user activation, enable the secondary broadcast receiver and program transition detector to begin monitoring a first broadcast signal currently tuned by the primary broadcast receiver, to allow tuning of the primary broadcast receiver by a user, and to automatically tune the primary broadcast receiver to the first broadcast signal upon signal by the selected program transition detector that one or more of the user-specific tune conditions have been met.

2. The system as set forth in claim 1 wherein the broadcast receivers are television receivers.

3. The system as set forth in claim 2 wherein the program transition detector further comprises a fixed period timer.

4. The system as set forth in claim 2 wherein the program transition detector further comprises a timer configured to expire at a user-specified integral multiple of a fixed time period.

5. The system as set forth in claim 2 wherein the program transition detector further comprises a volume change detector.

6. The system as set forth in claim 2 wherein the program transition detector further comprises a vocabulary change detector.

7. The system as set forth in claim 6 wherein the vocabulary change detector is further configured to analyze words from a decoded Secondary Audio Program.

8. The system as set forth in claim 6 wherein the vocabulary change detector is further configured to analyze words recognized from an audio portion of the broadcast signal.

9. The system as set forth in claim 2 wherein the program transition detector further comprises detecting a change in a content rating indicator.

10. The system as set forth in claim 9 wherein the content rating indicator comprises a V-chip indicator.

11. The system as set forth in claim 2 wherein the program transition detector comprises a scene-based program segment detector.

12. The system as set forth in claim 2 wherein the tuner controller is further configured to select a signal source for enabling the secondary receiver to monitor, and to select a signal source for tuning the primary receiver.

13. The system as set forth in claim 1 wherein the tuner controller is further configured to insert an alert tone or message into an audible output of the primary receiver upon the tuning action.

14. The system as set forth in claim 1 wherein the receivers comprise satellite signal receivers.

15. The system as set forth in claim 1 wherein the receivers comprise at least one pervasive computing device.

16. The system as set forth in claim 1 wherein the receivers comprise at least one web browser device.

17. The system as set forth in claim 1 further comprising a detector installer for receiving and installing one or more additional program transition detectors.

18. The system as set forth in claim 17 wherein the detector installer comprises a removable computer media.

19. The system as set forth in claim 18 wherein the detector installer comprises a download receiver.

20. The system as set forth in claim 1 wherein the set of user-specified tune conditions comprises a plurality of tune conditions wherein each tune condition is associated with at least one user indicator.

21. The system as set forth in claim 1 wherein the set of user-specified tune conditions comprises a priority indicator for resolving the user importance of each condition in the evaluation of the conditions.
