Data storage device and method for video processing and video frame searching using a key-value

1 . A data storage device comprising:

a memory; and

one or more processors, individually or in combination, configured to:

receive a plurality of key-value (KV) store commands from a host, wherein each KV store command comprises a key-value in which at least one video frames is represented as a single value addressed by a key instead of by a logical block address;

extract metadata for each video frame in the plurality of key-values based on object analysis in each video frame and based on a parameter in a header in each video frame;

group the key-values into a plurality of sub-groups according to the extracted metadata;

store each sub-group of the key-values in a different set of logical storage blocks in the memory;

perform post-processing on at least one video frame according to the extracted metadata;

store a post-processed version of the at least one video frame in a data-storage-device-specific space in the memory;

store the extracted metadata in a mapping data structure;

receive, from a host, a search command comprising a data value;

generate metadata for the data value received from the host;

perform a compare operation between the generated metadata for the data value received from the host with the extracted metadata stored in the mapping data structure to identify one or more video frames stored in the memory that have matching metadata;

retrieve the post-processed version of the one or more video frames from the memory; and

respond to the search command by sending, to the host, the post-processed version of the one or more video frames retrieved from the memory.

store, in a location in the memory that is addressed by a logical block address, a result of an operation from at least one other key-value pair.

3 . The data storage device of claim 1 , wherein the one or more processors, individually or in combination, are further configured to:

perform data management leveraging key-value group information.

4 . The data storage device of claim 1 , wherein the parameter comprises compression type.

5 . The data storage device of claim 1 , wherein the memory comprises a three-dimensional memory.

extracting metadata for each video frame in the plurality of key-values based on object analysis in each video frame and based on a parameter in a header in each video frame;

grouping the key-values into a plurality of sub-groups according to the extracted metadata;

storing each sub-group of the key-values in a different set of logical storage blocks in the memory;

performing post-processing on at least one video frame according to the extracted metadata;

storing a post-processed version of the at least one video frame in a data-storage- device-specific space in the memory;

storing the extracted metadata in a mapping data structure;

receiving, from a host, a search command comprising a data value;

generating metadata for the data value received from the host;

performing a compare operation between the generated metadata for the data value received from the host with the extracted metadata stored in the mapping data structure to identify one or more video frames stored in the memory that have matching metadata;

retrieving the post-processed version of the one or more video frames from the memory; and

responding to the search command by sending, to the host, the post-processed version of the one or more video frames retrieved from the memory.

14 . The method of claim 13 , wherein the parameter comprises inherent frame metadata.
