Abstract:
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.
