Abstract

A system, method and computer-readable medium are presented for providing real-time content-based navigation of live video programming. The method aspect of the invention comprises receiving a live video program, generating an index to the received live video program by extracting images and/or text from the video program, recording the live video program, presenting at least a portion of data associated with the generated index to a user, receiving user input regarding a portion of the recorded video program to which the user desires to navigate and playing back the recorded video program starting at the navigated portion identified by the user input.

Claims

1. A method for providing real-time content-based navigation of live video programming, the method comprising:

receiving a live video program;

generating an index to the received live video program by extracting images and/or text from the video program;

recording the live video program;

presenting at least a portion of data associated with the generated index to a user;

receiving user input regarding a portion of the recorded video program to which the user desires to navigate; and

playing back the recorded video program starting at the navigated portion identified by the user input.

2. The method of claim 1, wherein the portion of data associated with the index is at least one of:

images extracted from the live video program, text or a combination of text and images.

3. The method of claim 2, wherein the portion of data associated with the index is other data obtained from at least one of:

a source external from the live video program and data that accompanies the live video program.

4. The method of claim 3, wherein the external database is on the Internet.

5. The method of claim 1, wherein the presenting at least a portion of data associated with the generated index to a user occurs on a computing device different from the computing device which is used to view the video program.

6. The method of claim 5, wherein the computing device is a hand-held device that presents the extracted images and/or text to the user.

7. The method of claim 1, wherein generating the index further comprises using at least one of:

a content-based sampling module to extract images, a textual module to extract text and an automatic speech recognition module to extract text.

8. A system for providing real-time content-based navigation of live video programming, the system comprising:

a module configured to receive a live video program;

a module configured to generate an index to the received live video program by extracting images and/or text from the video program;

a module configured to record the live video program;

a module configured to present at least a portion of data associated with the generated index to a user;

a module configured to receive user input regarding a portion of the recorded video program to which the user desires to navigate; and

a module configured to play back the recorded video program starting at the navigated portion identified by the user input.

9. The system of claim 8, wherein the portion of data associated with the index is at least one of:

images extracted from the live video program, text or a combination of text and images.

10. The system of claim 9, wherein the portion of data associated with the index is other data obtained externally from at least one of:

a source external from the live video program and data that accompanies the live video program.

11. The system of claim 12, wherein the external database is on the Internet.

12. The system of claim 8, wherein the module that presents at least a portion of data associated with the generated index to a user occurs on a computing device different from the computing device which is used to view the video program.

13. The system of claim 12, wherein the computing device is a hand-held device that presents the extracted images and/or text to the user.

14. The system of claim 8, wherein the module configured to generate the index further uses at least one of:

a content-based sampling module to extract images, a textual module to extract text and an automatic speech recognition module to extract text.

15. A computer-readable medium storing instructions for controlling a computing device to provide real-time content-based navigation of live video programming, the instructions comprising:

receiving a live video program;

generating an index to the received live video program by extracting images and text from the video program;

recording the live video program;

presenting at least a portion of data associated with the generated index to a user;

receiving user input regarding a portion of the recorded video program to which the user desires to navigate; and

playing back the recorded video program starting at the navigated portion identified by the user input.

16. The computer-readable medium of claim 15, wherein the portion of data associated with the index is at least one of:

images extracted from the live video program, text or a combination of text and images.

17. The computer-readable medium of claim 16, wherein the portion of data associated with the index is other data obtained from at least one of:

a source external from the live video program and data that accompanies the live video program.

18. The computer-readable medium of claim 15, wherein the presenting at least a portion of data associated with the generated index to a user occurs on a computing device different from the computing device which is used to view the video program.

19. The computer-readable medium of claim 18, wherein the computing device is a hand-held device having a touch sensitive screen that presents the extracted images and/or text to the user.

20. The computer-readable medium of claim 15, wherein generating the index further comprises using at least one of:

a content-based sampling module to extract images, a textual module to extract text and an automatic speech recognition module to extract text.
