Abstract

Methods and systems for information querying are described. At least one recent image of a video signal may be accessed. Recent text associated with the at least one recent image may be accessed. A presentation image may be provided from the at least one recent image for presentation on a display. An original portion of the recent text may be identified within the presentation image. A selection of a user portion of the recent text may be received. An information source may be queried with the selection of the user portion of the recent text. The information source may be capable of using the selection to provide a result.

Claims

1. A method comprising:

accessing at least one recent image of a video signal;

accessing recent text associated with the at least one recent image;

providing a presentation image from the at least one recent image for presentation on a display, an original portion of the recent text being identified within the presentation image;

receiving a selection of a user portion of the recent text; and

querying an information source with the selection of the user portion of the recent text, the information source being capable of using the selection to provide a result.

2. The method of claim 1, wherein the accessing of the at least one recent image comprises:

receiving a stop command; and

selecting the at least one recent image of the video signal in accordance with the stop command.

3. The method of claim 1, wherein the providing of the presentation image further comprises:

providing the recent text for simultaneous presentation with the presentation image on the display.

4. The method of claim 1, wherein the receiving of the selection comprises:

receiving a text adjustment command for the recent text; and

selecting the user portion of the recent text in accordance with the text adjustment command.

5. The method of claim 4, further comprising:

applying named entity extraction to the recent text;

wherein the selecting of the user portion of the recent text is in accordance with the text adjustment command and the named entity extraction.

6. The method of claim 4, wherein the selecting of the user portion of the recent text is in accordance with the text adjustment command and tagging of at least one part of speech of the recent text.

7. The method of claim 4, further comprising:

recognizing at least one phrase in the recent text;

wherein the selecting of the user portion of the recent text is in accordance with the text adjustment command and the recognizing of the at least one phrase in the recent text.

8. The method of claim 1, wherein the receiving of the selection comprises:

receiving an image selection command;

selecting at least one different image of the video signal in accordance with the image selection command;

accessing different text associated with the at least one different image; and

providing the presentation image from the least one different image for presentation on the display, the original portion of the different text being identified for presentation within the presentation image.

9. The method of claim 8, wherein the different image and the different text are provided for presentation on the display.

10. The method of claim 1, wherein the receiving of the selection comprises:

receiving a history command;

providing a past query for presentation in accordance with the receiving of the history command; and

receiving the selection of the past query as the user portion of the recent text.

11. The method of claim 1, wherein the receiving of the selection comprises:

receiving a history command;

providing a past text selection for presentation in accordance with the receiving of the history command; and

receiving the selection of the past text selection as the user portion of the recent text.

12. The method of claim 1, further comprising:

performing facial recognition on the at least one recent image to receive facial recognition data;

wherein the querying of the information source is with the selection of the user portion of the recent text and the facial recognition data.

13. The method of claim 1, further comprising:

performing speech recognition on a portion of the video signal related to the at least one recent image to receive speech recognition data;

wherein the querying of the information source is with the selection of the user portion of the recent text and the speech recognition data.

14. The method of claim 1, wherein the recent text includes at least one of closed captioning text, optical character recognition text, speech recognition text, transcript text, or combinations thereof.

15. A method comprising:

receiving a query command;

accessing at least one media image associated with a media presentation in accordance with the receiving of the query command;

accessing recent text associated with the media presentation; and

querying an information source with a portion of the recent text, the information source being capable of using the portion to provide a result.

16. The method of claim 15, further comprising:

identifying one or more keywords from the recent text as the portion of the recent text.

17. The method of claim 15, further providing:

providing feedback regarding the querying of the information source.

18. The method of claim 15, further comprising:

receiving the result from the information source in response to the query; and

providing the result for presentation on the display.

19. The method of claim 15, wherein the media presentation includes at least one of an audio signal, a video signal, one or more embedded images, one or more accessed images, or combinations thereof.

20. The method of claim 15, wherein the result include at least one of text data, image data, audio data, video data, or combinations thereof.

21. A method comprising:

accessing a plurality of candidate terms associated with a media presentation;

receiving a predictive text entry for the media presentation;

identifying at least one identified term associated with the media presentation based on the plurality of candidate terms and the predictive text entry; and

querying an information source with the at least one identified term.

22. The method of claim 21, further providing:

providing feedback regarding the querying of the information source.

23. The method of claim 21, further comprising:

receiving the result from the information source in response to the query; and

providing the result for presentation on the display.

24. A machine-readable medium comprising instructions, which when implemented by one or more processors perform the following operations:

access at least one recent image of a video signal;

access recent text associated with the at least one recent image;

provide a presentation image from the at least one recent image for presentation on a display, an original portion of the recent text being identified within the presentation image;

receive a selection of a user portion of the recent text;

query an information source with the selection of the user portion of the recent text, the information source being capable of using the selection to provide a result.

25. A system comprising:

an image access module to access at least one recent image of a video signal;

a text access module to access recent text associated with the at least one recent image;

a provider module to provide a presentation image from the at least one recent image for presentation on a display, an original portion of the recent text being identified within the presentation image;

a selection receiver module to receive a selection of a user portion of the recent text; and

a source query module to query an information source with the selection of the user portion of the recent text, the information source being capable of using the selection to provide a result.
