Abstract

Methods, systems, and apparatus, including computer program products, for presenting subtitles. A video is played on a display of a device. A display mode for the video is detected. A subtitle is presented in one of a plurality of presentation formats based on the detected display mode.

Claims

1. A method, comprising:

playing a video on a display of a device;

detecting a display mode for the video; and

presenting a subtitle in one of a plurality of presentation formats based on the detected display mode.

2. The method of claim 1, wherein the detected display mode comprises one of:

scaling of a video to vertically fit the display, and

displaying of the video and at least one matte region adjacent to the video.

3. The method of claim 2, wherein presenting the subtitle in one of a plurality of presentation modes based on the detected display mode comprises presenting the subtitle in a transparent area overlaid on a video display region if the detected display mode requires scaling of the video to vertically fit the display.

4. The method of claim 2, wherein presenting the subtitle in one of a plurality of presentation modes based on the detected display mode comprises presenting the subtitle in the at least one matte region if the detected display mode requires displaying of the video and at least one matte region adjacent to the video.

5. The method of claim 4, wherein the subtitle is centered within the at least one matte region.

6. The method of claim 4, further comprising:

detecting overflow of a portion of the subtitle from the at least one matte region into a video display region; and

presenting the overflow portion of the subtitle in a transparent area overlaid on the video display region.

7. The method of claim 1, further comprising presenting user interface elements operable to scroll the subtitle.

8. The method of claim 1, wherein the plurality of presentation modes comprises:

presenting the subtitle in a transparent area overlaid on a video display region; and

presenting the subtitle in a matte region.

9. The method of claim 1, further comprising:

receiving a subtitle query; and

identifying one or more positions in the video associated with subtitles that match the subtitle query; and

presenting a frame of the video corresponding to one of the identified positions.

10. A device, comprising:

a display;

one or more processors; and

a computer-readable medium storing instructions for execution by the one or more processors, the instructions comprising instructions to;

play a video on the display;

detect a display mode for the video; and

present a subtitle in one of a plurality of presentation formats based on with the detected display mode.

11. The device of claim 10, wherein the detected display mode comprises one of:

scaling of a video to vertically fit the display, and

displaying of the video and at least one matte region adjacent to the video.

12. The device of claim 11, further comprising instructions to present the subtitle in a transparent area overlaid on a video display region if the detected display mode is scaling of the video to vertically fit the display.

13. The device of claim 11, further comprising instructions to present the subtitle in the at least one matte region if the detected display mode is displaying of the video and at least one matte region adjacent to the video.

14. The device of claim 13, wherein the subtitle is centered within the at least one matte region.

15. The device of claim 13, further comprising instructions to:

detect overflow of a portion of the subtitle from the at least one matte region into a video display region; and

present the overflow portion of the subtitle in a transparent area overlaid on the video display region.

16. The device of claim 10, further comprising instructions to present user interface elements operable to scroll the subtitle.

17. The device of claim 10, wherein the plurality of presentation modes comprises:

presenting the subtitle in a transparent area overlaid on a video display region; and

presenting the subtitle in a matte region.

18. The method of claim 10, further comprising instructions to:

receive a subtitle query; and

identify one or more positions in the video associated with subtitles that match the subtitle query; and

present a frame of the video corresponding to one of the identified positions.

19. A computer program product, encoded on a tangible program carrier, operable to cause a portable device to perform operations comprising:

playing a video on a display of a device;

detecting a display mode for the video; and

presenting a subtitle in one of a plurality of presentation formats based on with the detected display mode.

20. A method comprising:

determining a display mode for a video on a device, the display mode being one of a plurality of display modes for the device;

determining a subtitle presentation format based on the display mode, the subtitle presentation format being one of a plurality of subtitle presentation formats associated with the plurality of display modes; and

presenting a subtitle for the video on the device according to the subtitle presentation format.

21. The method of claim 20, further comprising presenting the video according to the display mode.

22. The method of claim 20, wherein determining a display mode for a video on a device comprises determining the display mode based on an aspect ratio of the video and an aspect ration of a display of the device.

23. A device, comprising:

a display;

one or more processors; and

a computer-readable medium storing instructions for execution by the one or more processors, the instructions comprising instructions to;

determine a display mode for a video on a device, the display mode being one of a plurality of display modes for the device;

determine a subtitle presentation format based on the display mode, the subtitle presentation format being one of a plurality of subtitle presentation formats associated with the plurality of display modes; and

presenting a subtitle for the video on the device according to the subtitle presentation format.
