Abstract

Advanced recording options are provided on a personal versatile recorder (PVR) or similar recording device. Television signals and associated electronic programming guide (EPG) data are received at a receiver (30). Recorded program material is stored in a storage device (60). A processor (75) provides for automatic suspending of recording, based on predetermined criteria, for at least a portion of time during which the one or more television programs would otherwise be recorded. Recording may be suspended when non-programming specific content (e.g., a commercial or emergency broadcast) is received at the PVR (20). Non-program specific content can be identified through the use of EPG data or Advanced Television Enhancement Forum (ATVEF) triggers. End of program notifiers may be provided which enable the PVR (20) to record the entire program, regardless of whether the program runs beyond its scheduled time. Recording may be optionally suspended where the program is a rerun.

Claims

1. A method for enabling advanced recording options on a personal versatile recorder (PVR), comprising:

receiving at the PVR a plurality of television signals;

providing for the recording of one or more television programs at the PVR;

automatically suspending recording, based on predetermined criteria detected by said PVR, for at least a portion of time during which said one or more television programs would otherwise be recorded; and

providing an end of program notifier in said television signal which identifies the end of the program;

wherein;

each television program has a program end time;

the PVR waits a predetermined amount of time after said program end time to receive the end of program notifier; and

recording of the program is terminated at the first to occur of (i) lapsing of the predetermined amount of time, and (ii) receipt of the end of program notifier.

2. A method in accordance with claim 1, wherein;

recording is suspended during the time when non-program specific content is received at the PVR; and

the predetermined criteria comprises EPG data.

3. A method in accordance with claim 1, wherein said predetermined criteria comprises at least one of EPG data or Advanced Television Enhancement Forum (ATVEF) triggers.

4. A method in accordance with claim 1, wherein:

said end of program notifier is provided in one of ATVEF trigger information, a vertical blanking interval of an analog television signal, or a program identifier of a digital television signal.

5. A method in accordance with claim 1, wherein:

recording is suspended when a rerun of a program is detected; and

the predetermined criteria comprises EPG data.

6. A method for enabling advanced recording options on a personal versatile recorder (PVR), comprising:

receiving at the PVR a plurality of television signals;

providing for the recording of one or more television programs at the PVR;

automatically suspending recording, based on predetermined criteria detected by said PVR, for at least a portion of time during which said one or more television programs would otherwise be recorded;

providing additional information to the PVR indicating that a program being recorded supports end of program notifiers, thereby configuring said PVR to terminate the recording based on a notifier;

providing an end of program notifier in said television signal which identifies the end of the program; and

continuing recording of the program until receipt of the notifier;

7. A method in accordance with claim 6, wherein:

said additional information is provided in one of EPG data, ATVEF trigger information, a vertical blanking interval of an analog television signal, or a program identifier of a digital television signal.

8. A personal versatile recorder (PVR) having advanced recording options, comprising:

a receiver for receiving a plurality of television signals;

a storage device for recording of one or more television programs at the PVR; and

a processor for automatically suspending recording, based on predetermined criteria detected by said processor, for at least a portion of time during which said one or more television programs would otherwise be recorded;

wherein;

an end of program notifier is provided in said television signal which identifies the end of the program;

each television program has a program end time;

the PVR waits a predetermined amount of time after said program end time to receive the end of program notifier; and

recording of the program is terminated at the first to occur of (i) lapsing of the predetermined amount of time, and (ii) receipt of the end of program notifier.

9. Apparatus in accordance with claim 8, wherein;

recording is suspended during the time when non-program specific content is received at the PVR; and

the predetermined criteria comprises EPG data.

10. Apparatus in accordance with claim 8, wherein said predetermined criteria comprises at least one of EPG data or Advanced Television Enhancement Forum (ATVEF) triggers.

11. Apparatus in accordance with claim 8, wherein:

end of program notifiers are provided in one of ATVEF trigger information, a vertical blanking interval of an analog television signal, or a program identifier of digital television signal.

12. Apparatus in accordance with claim 8, wherein:

recording is suspended when a rerun of a program is detected; and

the predetermined criteria comprises EPG data.

13. A personal versatile recorder (PVR) having advanced recording options, comprising:

a receiver for receiving a plurality of television signals;

a storage device for recording of one or more television programs at the PVR; and

a processor for automatically suspending recording, based on predetermined criteria detected by said processor, for at least a portion of time during which said one or more television programs would otherwise be recorded;

wherein;

an end of program notifier is provided in said television signal which identifies the end of the program;

recording of the program is continued until receipt of the notifier; and

additional information is provided to the PVR indicating that the program supports end of program notifiers, thereby configuring said PVR to terminate the recording based on a notifier.

14. Apparatus in accordance with claim 13, wherein:

said additional information is provided in one of EPG data, ATVEF trigger information, a vertical blanking interval of an analog television signal, or a program indentifier of a digital television signal.
