Figure 8-2 – Functional entities in MC-Streaming architecture
8.3.1 MC-Streaming application control functional entity (MSAC-FE)

MSAC-FE allows multi-connection devices, i.e., the MUE, to choose and/or purchase content on demand.
When it receives a request from a MC-Streaming device, MSAC-FE fulfils authentication and authorization by
interacting with MSUP-FE, or with related information obtained from MSUP-FE. MSAC-FE provides
application control logic based on the application-user profile, content metadata and other relevant
information. MSAC-FE is also responsible for interaction control, such as programme selection, and
forwarding and rewinding. Interaction between users (i.e., "users share programmes among friends") is one
of the MSAC-FE's responsibilities.
If needed, MSAC-FE can optionally request or inspect the content preparation procedure, which is fulfilled
by MSCC-FE, since MSAC-FE is able to interact with the MUE and can obtain some MUE or user related
information.
8.3.2 MC-Streaming application-user profile functional entity (MSUP-FE)

MSUP-FE stores relevant information about streaming application and service subscribers. Information in
MSUP-FE can optionally include:
a) Global settings (e.g., language preference).
b) Capabilities of MC-Streaming terminal devices.
c) Authentication and authorization information of MC-Streaming terminal devices and subscribers.
d) MC-Streaming service settings, e.g., linear TV settings, on demand service settings, etc.
