Abstract

One embodiment provides a method and apparatus for obtaining metadata program information during channel changes. The method includes the capture of an on-screen display that is rendered by a rendering device such as, for example, a digital television system. The on-screen display may be generated by an access device such as a set-top box in response to a program selection event. Once captured, the on-screen display may be decoded to determine metadata for a program selected by the program selection event. In one embodiment, decoding may be provided using pattern matching, optical code recognition (OCR) or other like decoding technique for decoding a video frame to determine metadata for a program selected by the program selection event. In one embodiment, a copy of the program in conjunction with the captured metadata are stored within the persistent memory of a digital television device. Other embodiments are described and claimed.

Claims

1. A method comprising:

capturing an on-screen display that is rendered by a rendering device, the on-screen display generated by an access device in response to a program selection event; and

decoding the captured on-screen display to determine metadata for a program selected by the program selection event.

2. The method of claim 1 further comprising:

recording the program selected by the program selection event in conjunction with the determined metadata for the program selected by the program selection event.

3. The method of claim 1, wherein prior to the capturing of the on-screen display, the method further comprising:

monitoring remote control commands issued to an access device to detect an activate command that activates a mode of operation having potential for selection of a program;

upon receipt of the activate command, further monitoring remote control commands for a selection command that selects a program; and

detecting a program selection event if a selection command is identified that selects a program.

4. The method of claim 1, wherein decoding the captured on-screen display further comprising:

optical character recognition (OCR) processing a video frame of the captured on-screen display containing the metadata related to the selected program to extract the metadata associated with the selected program.

5. The method of claim 1, wherein decoding the captured on-screen display further comprising:

determining one or more of a program name, a start time and an end time of the program selected by the program selection event; and

searching a network to determine additional program information according to the one or more of the program name, start time and end time of the program selected by the program selection event.

6. The method according to claim 3, carried out in a digital television device, wherein the digital television device is not a target device of at least one of the activate and selection commands.

7. The method of claim 1 further comprising:

issuing an information command that causes the access device to generate a video frame containing metadata associated with the program; and

optical character recognition (OCR) processing the video frame containing the metadata relating to the program to extract additional metadata associated with the program.

8. The method of claim 7, wherein the access device comprises a television set top box that is a target of a remote control selection command, and wherein the process is carried out on a digital television device.

9. A computer readable storage medium storing instructions which, when executed on a programmed processor, carry out a process according to claim 1.

10. The method of claim 1 wherein the program selection event is one of a channel tuning event, a selection from a list of recorded programs on a personal video recorder (PVR), a selection from a list of Video on Demand (VOD) programs, a selection to play package media, a selection from a list of content stored on portable media, a selection from a list of content stored on portable devices.

11. The method of claim 1 wherein the metadata is at least one of a program name, a parental rating, a program duration, a channel number program was recorded from, channel name program was recorded from, current data and time and the current list of favorites which is active.

12. A method comprising:

detecting a remote control command that selects a program;

capturing a video frame that is rendered by a rendering device, the video frame generated by an access device that is a target of the detected remote control command; and

decoding the captured video frame to determine metadata regarding the selected program.

13. The method of claim 12, wherein the rendering device is not a target of the detected remote control command.

14. The method of claim 12, wherein detecting the remote control command further comprises:

monitoring remote control commands to detect an activate command that activates a mode of operation having potential for selection of a program;

upon detection of the activate command, further monitoring remote control commands to detect a selection command that selects a program; and

upon detection of the selection command, issuing an information command that causes the access device to generate a video frame containing additional metadata associated with the program;

15. The method of claim 12, further comprising recording the metadata in association with recording a copy of the program.

16. The method of claim 12, further comprising:

generating, by the access device that is a target of the detected remote control command, an on-screen display including metadata regarding the selected program; and

optical character recognition (OCR) processing the on-screen display containing the metadata relating to the program to extract the metadata associated with the program.

17. A system comprising:

a digital television device including a remote control command receiver to detect a remote control command that selects a program and a video receiver;

decode logic to capture a video frame that is rendered by the video receiver that receives the video frame, the decode logic to decode the captured video frame to determine metadata regarding the selected program; and

a network coupled to the digital television device, the digital television device to request additional program information regarding the selected program according to the determined metadata regarding the selected program.

18. The system of claim 17, wherein an access device to generate a video frame containing metadata associated with the program in response to the remote control command that selects the program.

19. The system of claim 18, wherein the access device comprises a set-top box that is a target of the remote control command that selects a program.

20. The system of claim 17, wherein the decode logic further comprises:

optical character recognition (OCR) logic to process a video frame of the captured on-screen display containing the metadata related to the selected program to extract the metadata associated with the selected program.

21. The system of claim 17, wherein the decode logic is further to, upon detection of the remote control command that selects the program, issue an information command that causes an access device to generate an on-screen display containing additional metadata associated with the program

22. The system of claim 17, wherein the digital television is not a target of the remote control command that selects the program.
