Abstract
A multimedia on demand system includes a host, and a computational storage drive. The host transmits, to the computational storage drive, a first request for multimedia on demand. The computational storage drive, in response to the first request, performs 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 including a flow control and one or more of a codec process or a multiplexing process for the multimedia. The computational storage drive transmits the on demand result to the host, and the host receives the on demand result from the computational storage drive.
