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.

First claim

What is claimed is:

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 subtitles, wherein the presentation format is selected in response to the detected display mode; and
presenting subtitles in the selected presentation format;
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 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 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 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. The method of claim 1 , further comprising:
generating, for presentation within a user interface displayed on the display, one or more options for scrolling the presented subtitles.

11. The method of claim 10 , wherein the one or more options include an option for scrolling the presented subtitles forward to display subtitles corresponding to a later time position of the video content.

12. The method of claim 10 , wherein the one or more options include an option for scrolling the presented subtitles backward to display subtitles corresponding to an earlier time position of the video content.

13. 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:
process a video for display on the display;
detect 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;
select one of a plurality of presentation formats for presenting subtitles, wherein the presentation format is selected in response to the detected display mode;
in a first detected display mode, present subtitles in a first presentation format in which the subtitles are not overlaid on the video; and
in a second detected display mode, present subtitles in a second presentation format in which the subtitles are at least partially overlaid on the video.

14. The device of claim 13 , 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.

15. The device of claim 14 , 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.

16. The device of claim 14 , further comprising instructions to present the subtitle 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.

17. The device of claim 16 , wherein the subtitle is centered with the at least one matte region.

18. The device of claim 16 , 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.

19. The device of claim 13 , further comprising instructions to present user interface elements operable to scroll the subtitle.

20. The device of claim 13 , 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.

21. The device of claim 13 , 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.

22. A non-transitory computer-readable medium including one or more sequences of instructions which, 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, 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 subtitles, wherein the presentation format is selected in response to the detected display mode; and
in a first detected display mode, presenting subtitles in a first presentation format in which the subtitles are not overlaid on the video, wherein the presented subtitles scroll automatically as the video is played based on a time position of the video content, wherein subtitles are hidden as the time position of the video content progresses; and
in a second detected display mode, presenting subtitles that are at least partially overlaid on the video, wherein the presented subtitles scroll automatically as the video is played based on a time position of the video content, and wherein subtitles are hidden as the time position of the video content progresses.

23. 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 and 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;
determining a subtitle presentation format based at least in part 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
in a first display mode, generating subtitles
