Abstract
Aspects of a storage device include a memory comprising a plurality of memory locations each associated with a physical address, the memory configured to store a plurality of video frames received from a host device at the physical addresses, each of the video frames being associated with a logical address; and a controller configured to store in a partition of the memory the logical addresses for a subset of the video frames, the controller being configured to provide the host access to the partition to read the logical addresses during rapid playback of the video frames. Aspects of the host device include a processor configured to write the video frames to the storage device, to identify the subset of the video frames to the storage device, and during rapid playback, to access the storage device to read the logical address for each video frame in the subset.
