Abstract

A method, program product and system are provided for optimizing recording requests to minimize electricity usage for a network of DVRs. The disclosed methodology analyzes upcoming recording requests against a schedule guide including both local and networked DVRs. Overlaps in requested recordings and broadcasts during same or close proximity time slots are identified. Requested recordings are then rescheduled to optimally overlap recording times based upon the number of tuners in each DVR system. Changes in recording schedules are then communicated to other interconnected DVRs in a network.

Claims

1. A computer-implemented method for optimizing power requirements of a video recorder system in recording video programs selected for recording by a user input to a user video recorder, said user video recorder being configured for being interconnected with other video recorders in a network, said method comprising:

receiving a user request to record a selected video program at a user selected recording time;

in response to said receiving, immediately searching a program listing to determine if said selected video program is scheduled to be played at a different time than said user selected recording time;

if it is determined that said selected video program is scheduled to be played at said different time, then searching a listing of programs scheduled to be recorded on digital video recorders (DVRs) in said network to find an available DVR, said available DVR including at least two tuners wherein only one of said tuners is scheduled to be recording a video program at said different time;

determining that recording said selected video program on said available recorder in said network instead of said user video recorder would result in a cost savings to said user, said cost savings being realized by enabling at least partially concurrent operation of said two or more tuners of said available recorder in recording said selected video program at said available recorder; and

automatically recording of said selected video program at said available recorder without further user input, in response to said determining of said cost savings to said user.

2. The method as set forth in claim 1 wherein said cost savings results from said available recorder being enabled to record said selected video program at less cost to said user than recording said selected video program on said user video recorder.

3. The method as set forth in claim 2 wherein said cost savings results from said available recorder having lower power requirements than said user video recorder.

4. The method as set forth in claim 1 wherein said different recording time is during a period when electrical energy usage rates are lower than during said user selected recording time.

5. The method as set forth in claim 1 and further including:

providing a recording delay period, said recording delay period being representative of an acceptable maximum delay for delaying a recording of said selected video program from said user selected recording time to a time subsequent to said user selected recording time;

determining by said video recorder system of a subsequent recording time at which said selected video program is being re-broadcast;

determining that said subsequent recording time is within said recording delay period;

determining that a recording of said selected video program at said subsequent recording time at said available recorder would result in said operational cost savings; and

recording of said selected video program at said available recorder at said subsequent recording time instead of said user selected recording time.

6. The method as set forth in claim 5 wherein said recording delay period is determined by said user.

7. The method as set forth in claim 5 and further including:

presenting a user selection screen to said user on said display device in response to said receiving, said user selection screen being operable for enabling said user to input said recording delay period.

8. The method as set forth in claim 5 wherein said recording delay period is a pre-set value applied by said video recorder system.

9. The method as set forth in claim 5 wherein said selected video program is recorded at said user selected recording time if said subsequent recording time is not within said recording delay period.

10. A computer program product comprising one or more computer-readable, tangible storage devices and computer-readable program instructions stored on the one or more computer-readable, tangible storage devices for optimizing power requirements of a video recorder system in recording user selected video programs selected for recording by a user input to a user video recorder, said user video recorder being configured for being interconnected with other video recorders in a network, the computer-readable program instructions, when executed by a processing system, being operable for implementing a method comprising:

receiving a user request to record a selected video program at a user selected recording time;

in response to said receiving, immediately searching a program listing to determine if said selected video program is scheduled to be played at a different time than said user selected recording time;

if it is determined that said selected video program is scheduled to be played at said different time, then searching a listing of programs scheduled to be recorded on digital video recorders (DVRs) in said network to find an available DVR, said available DVR including at least two tuners wherein only one of said tuners is scheduled to be recording a video program at said different time;

determining that recording said selected video program on said available recorder in said network instead of said user video recorder would result in a cost savings to said user, said cost savings being realised by enabling at least partially concurrent operation of said two or more tuners of said available recorder in recording said selected video program at said available recorder; and

automatically recording of said selected video program at said available recorder without further user input, in response to said determining of said cost savings to said user.

11. The computer program product as set forth in claim 10 wherein said cost savings results from said available recorder being enabled to record said selected video program at less cost to said user than recording said selected video program on said user video recorder.

12. The computer program product as set forth in claim 11 wherein said cost savings results from said available recorder having lower power requirements than said user video recorder.

13. The computer program product as set forth in claim 11 wherein said different recording time is during a period when electrical energy usage rates are lower than during said user selected recording time.

14. The computer program product as set forth in claim 10 and further including:

providing a recording delay period, said recording delay period being representative of an acceptable maximum delay for delaying a recording of said selected video program from said user selected recording time to a time subsequent to said user selected recording time;

determining by said video recorder system of a subsequent recording time at which said selected video program is being re-broadcast;

determining that said subsequent recording time is within said recording delay period;

determining that a recording of said selected video program at said subsequent recording time at said available recorder would result in said operational cost savings; and

recording of said selected video program at said available recorder at said subsequent recording time instead of said user selected recording time.

15. The computer program product as set forth in claim 14 wherein said recording delay period is determined by said user.

16. The computer program product as set forth in claim 14 wherein said method further includes:

presenting a user selection screen to said user on said display device in response to said receiving, said user selection screen being operable for enabling said user to input said recording delay period.

17. The computer program product as set forth in claim 14 wherein said recording delay period is a pre-set value applied by said video recorder system.

18. A video recorder system for optimizing power requirements in recording video programs selected for recording by a user input to a user video recorder, said user video recorder being configured for being interconnected with other video recorders in a network, said system comprising:

receiving means for receiving a user input request to said user video recorder to record a selected video program at a user selected recording time;

a computer system operable in response to said user input request for searching a program listing to determine if said selected video program is scheduled to be played at a different time than said user selected recording time;
