Information technology - Multimedia application format (MPEG-A) - Part 16: Publish/Subscribe Application Format

This document specifies four formats that are used by parties communicating using the Publish/Subscribe (PubSub) communication model for their multimedia communication purposes.

The PubSub parties are: Publisher, Subscriber, Match Service Provider (MSP) and Consumer and the formats employed are Resource Information (RI), Publication Information (PI), Subscription Information (SI) and Notification Information (NI).

This document specifies RI, PI, SI and NI in such a way that typical multimedia communication requirements can be supported. The following is a non-exhaustive list of such requirements.

— The Publisher can

— describe the Resource for consumption purposes,

— define the contract that will bind the Publisher and a Consumer,

— request a device to report use of the Resource,

— describe the Resource for distribution purposes,

— define the contract that will bind the Publisher and a Match Service Provider (MSP) of a match involving the Publication, and

— request the MSP to notify/not to notify a list of users.

— The Subscriber can

— query the Resource,

— define the contract that will bind the Subscriber and a Match Service Provider (MSP), and

— request the MSP to notify/not to notify a list of users of a match involving the Subscription.
