Four Work Items of MPEG-UD
• MPEG-UD elements
– UD (User Description)• Contains static and dynamic information about the user
– CD (Context Description)• Describes the environmental situation in which the user operates or is located
– SD (Service Description)• contains pertinent information (including security settings) about the service
(or a set of sub-services)
– RD (Recommendation Description)• Recommended Information elements provided to the applications, in a struc-
tured, efficient, and compact form, when a customer requests a service in a certain environment
