Samsung patents storage drive that processes video before sending it

1. A multimedia on demand method comprising: receiving, by a computational storage drive from a host, a first request for multimedia on demand; in response to the first request, performing, by the computational storage drive, an on demand processing process for multimedia that corresponds to the first request to generate a corresponding on demand result, the on demand processing process comprising a flow control and at least one of a codec process or a multiplexing process for the multimedia; and transmitting the on demand result to the host, wherein the computational storage drive comprises a processor and an integrated circuit chip; and wherein performing the on demand processing process comprises: performing, by the processor, the flow control, the flow control comprising a codec control, and a request control that is performed based on the request control; performing, by the integrated circuit chip, at least one of the codec process or the multiplexing process, wherein the processor comprises a stream controller and a codec controller; wherein the integrated circuit chip comprises a multiplexer and a codec; wherein performing, by the processor, the flow control comprises: performing, by the stream controller, the request control; and performing, by the codec controller, the codec control; wherein performing, by the stream controller, the request control comprises receiving the first request, and in response to the first request, performing: in a case in which request content of the first request is to obtain source data, requesting the source data from a controller of the computational storage drive; in a case in which encoding parameters of the source data do not satisfy a preset requirement of encoding parameters, instructing the codec controller by a transcoding request to control the codec to transcode the source data and use the transcoded source data as the on demand result; in a case in which the encoding parameters of the source data satisfies the preset requirement of encoding parameters, instructing the codec controller by an encapsulation request to control the multiplexer to encapsulate the source data and use the encapsulated source data as the on demand result; and in a case in which the request content of the first request is to change a resolution or to change an encapsulation format, instructing the codec controller by the encapsulation request to control the multiplexer to encapsulate corresponding multimedia data in accordance with the request content of the first request and use the encapsulated multimedia data as the on demand result; and wherein performing, by the codec controller, the codec control comprises: controlling an operation of the codec and the multiplexer based on the codec control; and setting codec parameters of the codec based on the first request.
