US Patent 11036807 Metadata generation at the storage edge

A controller, for use in a storage device of a data processing system, includes a host interface, a memory interface and one or more processors. The host interface is configured to communicate over a computer network with one or more remote hosts of a data processing system. The memory interface is configured to communicate locally with a non-volatile memory of the storage device. The one or more processors are configured to manage local storage or retrieval of media objects at the non-volatile memory, and to selectively compute metadata that defines content characteristics of media objects that are stored, or that are to be stored, in the non-volatile memory.
