System and method for content-based navigation of live and recorded TV and video programs
First Claim
1. A method comprising:
- receiving a broadcast video program from a first source;
performing an analysis of images and text displayed in the video program, to generate a content-based index, wherein the content-based index;
is generated independent of index information transmitted with the broadcast video program; and
is generated by combining extracted images and the text from the video program with first network-based content provided by an external source, the first network-based content being transmitted separately from the broadcast video program;
automatically, via a processor, supplementing the content-based index with second network-based content as the content-based index is generated, wherein the second network-based content is from a second source that is distinct from the first source and the external source;
presenting a search field, wherein presenting of the search field occurs on a first computing device different from a second computing device which displays the broadcast video program, wherein the first computing device is a hand-held device;
receiving user input in the search field;
searching the content-based index to identify a location in the video program associated with the user input; and
sending a signal to the second device to play back the video program starting at the location.

Abstract
A system, method and computer-readable medium are presented for providing real-time content-based navigation of live video programming. The video programming is received and a searchable database is generated. 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 search to a portion of the recorded video program to which the user desires to navigate and playing back the recorded video program starting at the searched portion identified by the user input. The search may be of an image and/or text portion of the presentation.

8. A system comprising:
-
a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, result in the processor performing operations comprising; receiving a broadcast video program from a first source; performing an analysis of images and text displayed in the video program, to generate a content-based index, wherein the content-based index; is generated independent of index information transmitted with the broadcast video program; and is generated by combining extracted images and the text from the video program with first network-based content provided by an external source, the first network-based content being transmitted separately from the broadcast video program; automatically supplementing the content-based index with second network-based content as the content-based index is generated, wherein the second network-based content is from a second source that is distinct from the first source and the external source; presenting a search field, wherein presenting of the search field occurs on a first computing device different from a second computing device which displays the broadcast video program, wherein the first computing device is a hand-held device; receiving user input in the search field; searching the content-based index to identify a location in the video program associated with the user input; and sending a signal to the second device to play back the video program starting at the location. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-readable storage device having instructions stored which, when executed by a computing device, result in the computing device performing operations comprising:
-
receiving a broadcast video program from a first source; performing an analysis of images and text displayed in the video program, to generate a content-based index, wherein the content-based index; is generated independent of index information transmitted with the broadcast video program; and is generated by combining extracted images and the text from the video program with first network-based content provided by an external source, the first network-based content being transmitted separately from the broadcast video program; automatically supplementing the content-based index with second network-based content as the content-based index is generated, wherein the second network-based content is from a second source that is distinct from the first source and the external source; presenting a search field, wherein presenting of the search field occurs on a first computing device different from a second computing device which displays the broadcast video program, wherein the first computing device is a hand-held device; receiving user input in the search field; searching the content-based index to identify a location in the video program associated with the user input; and sending a signal to the second device to play back the video program starting at the location. - View Dependent Claims (16, 17, 18, 19, 20)
