Additional improvements to nbmp standard

An apparatus for processing media content in Moving Picture Experts Group (MPEG) Network Based Media Processing (NBMP), the apparatus comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• first obtaining code configured to cause the at least one processor to obtain, from an NBMP source, a workflow for processing the media content, the workflow having a workflow descriptor (WD);
• second obtaining code configured to cause the at least one processor to obtain, based on the workflow, a task for processing the media content, the task having a task descriptor (TD) included in the WD of the workflow;
• third obtaining code configured to cause the at least one processor to obtain, based on the task at least one among the one or more functions, each of the at least one among the one or more functions having a function descriptor (FD);
• processing code configured to cause the at least one processor to process the media content, using the workflow, the task, and the at least one among the one or more functions,
• wherein the WD comprises a plurality of descriptors, in addition to the TD, the plurality of descriptors including a scheme descriptor, a general descriptor, an input descriptor, an output descriptor, a processing descriptor, and a requirement descriptor.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor of an apparatus for processing media content in Moving Picture Experts Group (MPEG) Network Based Media Processing (NBMP), cause the at least one processor to:

• obtain, from an NBMP source, a workflow for processing the media content, the workflow having a workflow descriptor (WD);
• based on the workflow, obtain a task for processing the media content, the task having a task descriptor (TD) included in the WD of the workflow;
• based on the task, obtain at least one among the one or more functions, each of the at least one among the one or more functions having a function descriptor (FD);
• and
• process the media content, using the workflow, the task, and the at least one among the one or more functions,
• wherein the WD comprises a plurality of descriptions, in addition to the TD, the plurality of descriptions including a scheme descriptor, a general descriptor, an input descriptor, an output descriptor, a processing descriptor, and a requirement descriptor.
