Pre-fetch of data using seek intervals
A data storage device comprises a non-volatile memory, a buffer, and a controller. The controller is configured to decode a media file to extract timestamp information related to a set of frames of the media file and receive, from a host, a seek command associated with playback of the media file. The seek command includes a seek interval. The controller is further configured to remove at least a portion of the set of frames based at least in part on the seek interval and the extracted timestamp information and transmit a subset of the set of frames, not including the removed at least a portion of the set of frames, to the host.
1. A data storage device comprising:
a non-volatile memory;
a buffer; and
a controller configured to:
decode a media file to extract timestamp information related to a set of frames of the media file;
receive, from a display device, a seek command associated with playback of the media file, the seek command including a seek interval;
receive, from the display device, a logical block address (LBA) indicating a current playback position of the media file;
remove at least a portion of the set of frames based at least in part on the seek interval, the current playback position, and the extracted timestamp information; and
transmit a subset of the set of frames, not including the removed at least a portion of the set of frames, to the display device.
2. The data storage device of claim 1 , wherein the media file is a video file.
3. The data storage device of claim 1 , wherein the controller is further configured to store the extracted timestamp information.
4. The data storage device of claim 1 , wherein the seek interval is indicated in a unit of time.
5. The data storage device of claim 1 , wherein the seek interval is indicated as a multiple of a value.
6. The data storage device of claim 1 , wherein the removed at least a portion of the set of frames includes a repeating pattern of frames.
7. The data storage device of claim 1 , wherein the seek interval relates to a fast-forward operation.
8. The data storage device of claim 1 , wherein the seek interval relates to a reverse operation.
9. The data storage device of claim 1 , wherein the seek command includes an indication of a length of a seek operation.
10. A method comprising:
decoding a media file to extract timestamp information related to a set of frames of the media file;
receiving, from a display device, a seek command associated with playback of the media file, the seek command including a seek interval;
receiving, from the display device, a logical block address (LBA) indicating a current playback position of the media file;
removing at least a portion of the set of frames based at least in part on the seek interval, the current playback position, and the extracted timestamp information; and
transmitting a subset of the set of frames, not including the removed at least a portion of the set of frames, to the display device.
11. The method of claim 10 , wherein the media file is a video file.
12. The method of claim 10 , further comprising storing the extracted timestamp information.
13. The method of claim 10 , wherein the seek interval is indicated in a unit of time.
14. The method of claim 10 , wherein the seek interval is indicated as a multiple of a value.
15. The method of claim 10 , wherein the removed at least a portion of the set of frames includes a repeating pattern of frames.
16. The method of claim 10 , wherein the seek interval relates to a fast-forward operation.
17. The method of claim 10 , wherein the seek interval relates to a reverse operation.
18. The method of claim 10 , wherein the seek command includes an indication of a length of a seek operation.
19. A data storage device comprising:
means for decoding a media file to extract timestamp information related to a set of frames of the media file;
means for receiving, from a display device, a seek command associated with playback of the media file, the seek command including a seek interval;
means for receiving, from the display device, a logical block address (LBA) indicating a current playback position of the media file;
means for removing at least a portion of the set of frames based at least in part on the seek interval, the current playback position, and the extracted timestamp information; and
means for transmitting a subset of the set of frames, not including the removed at least a portion of the set of frames, to the display device.
20. The data storage device of claim 1 , wherein the display device is a media playback device.
