Presentation of Structured Information (PSI)
MPEG wants to develop a standard that enables declarative representation of structured information such as MPEG-21 Digital Item to maintain interoperable presentation of it across different implementations by conforming such standard, so-called PSI (Presentation of Structured Information). MPEG received two responses to the call for proposals (N9905) and associated requirements (N9904):
M15622 Proposal for the Presentation of Structured Information
M15649 Timed Representation of Metadata for the Presentation of Structured Information (PSI)
Since most of the requirements are at least partially fulfilled, the technical work started in the Systems Group.
