Development of standard for Publish/Subscribe Application Format underway at MPEG 111

Development of standard for Publish/Subscribe Application Format underway at MPEG 111

At its 111th meeting, MPEG has started working on an application format that enables communication between user posting or searching for multimedia information to an intermediate service. The new format defined by ISO/IEC 23000-16 Publish/Subscribe Application Format (PSAF) enables Publishers who create and store Resource Information (RI) to send Publications Information (PI). Subscribers can then send Subscriptions Information (SI) to Match Service Providers (MSP) who perform matches of Subscriptions with Publications and send Notification Information (NI) to users listed in PIs and SIs when a Match has been found.

MPEG technologies used in PSAF, such as User Description and Contract Expression Language allow automatic management of business relationships between Publisher and MSP, and Subscriber and MSP.

INCITS/L3 on Coding of Audio, Picture, Multimedia, and Hypermedia is the U.S. TAG to the ISO/IEC JTC 1/SC 29 Subcommittee on MPEG. To participate in this activity or learn more information, please contact the INCITS/L3 Chair, Dr. Arianne Hinds at A.Hinds@cablelabs.com.
