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:

selecting a video for display on a display of a device;

detecting a display mode for the video, wherein the display mode is based on an aspect ratio of the video, an aspect ratio of the display of the device, and a user preference;

selecting one of a plurality of presentation formats for presenting captions, wherein the presentation format is selected in response to the detected display mode;

presenting captions in the selected presentation format from the one of a plurality of presentation formats based on the detected display mode;

wherein the method is performed by one or more processors.

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

scaling of a video to vertically fit the display, and

formatting the video and at least one matte region adjacent to the video for display on the display of the device.

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

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

6. The method of claim 4, further comprising:

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

presenting the overflow portion of the caption 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 caption.

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

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

presenting the caption in a matte region.

9. The method of claim 1, further comprising:

receiving a caption query; and

identifying one or more positions in the video associated with captions that match the caption 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 non-transitory computer-readable medium including one or more sequences of instructions that, when executed by one or more processors, causes;

selecting a video for display on a display of a device;

detecting a display mode for the video; and

presenting captions in one of a plurality of presentation formats based on the detected display mode;

wherein the method is performed by one or more processors.

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

scaling of a video to vertically fit the display, and

formatting the video and at least one matte region adjacent to the video for display on the display.

12. The device of claim 11, further comprising instructions to present the caption 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 caption in the at least one matte region if the detected display mode is formatting the video and at least one matte region adjacent to the video for display on the display.

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

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

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

present the overflow portion of the caption 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 caption.

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

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

presenting the caption in a matte region.

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

receive a caption query; and

identify one or more positions in the video associated with captions that match the caption query; and

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