Media Value Chain Ontology
As a response to its Call for Proposals (N9907), MPEG received two contributions by three organisations:
M15631 Ontology for IP Media Networks (IPM-Net)
M15698 Proposing an Architecture of MPEG Media Value Chain Ontology
The evaluation of the response to the call extracted sufficient technology to start the technical work for the standard. Therefore, MVCO was transferred to the Systems Group. It will become part of MPEG 21.
Interactive Music Application Format MAF
A MAF supporting playback of multiple audio streams was requested at the 84th meeting. Compared to the music player MAF, additional streams have to play synchronously. An additional requirement was presented at this meeting:
M15710: iKlax Requirements for MPEG Interactive Music
In order to provide some control over the playback to the music author, constraints on how different streams are played back have to be definable.
It appears that no new coding technology has to be developed in order to enable the available requirements.
A Draft Call for Proposals on Interactive Music Application Format (N10109) was issued. We expect to finalize the call at the next meeting. Since the companies presenting requirements are already selling products in the market, a timely development of a MAF appears to be important.
