e) User preferences and subscription information, such as user specific settings, programmes being
ordered, etc.
f) Security and privacy settings, e.g., required security level of a subscriber, parent control information,
etc.

8.3.3 MC-Streaming content control functional entity (MSCC-FE)
MSCC-FE provides content management and control functions. It is responsible for content preparation and
content protection. MSCC-FE can optionally provide content distribution functions.
a) Content preparation
MSCC-FE is responsible for preparing and aggregating the contents as received from the content provider
functions. MSCC-FE may edit the content or insert some watermark for content tracing before dispatching it
to other functional entities.
b) Content protection
MSCC-FE is responsible for protecting the service and contents from illegal access. This is performed by
verifying the subscriber's or service authorization, according to the subscriber's profile, subscription
information and authorization token. Encryption methods and access control mechanisms (e.g., role based
access control) can be employed to fulfil this functionality.

c) Content distribution
MSCC-FE can optionally provide content distribution function in some cases, especially if the multi-
connection architecture is not supported by the underlying network. Content delivery mechanisms and
technologies (e.g., CDN, multicasting, broadcasting, and P2P overlay network) can be employed; this is
decided according to the existing underlying network, operation requirements, etc.

8.3.4 MC-Streaming content delivery functional entity (MSCD-FE)
MSCD-FE is responsible for delivering streaming content from MSCC-FE to the subscriber. In this
Recommendation, the multi-connection architecture is the preferred model to provide content delivery.
However if the multi-connection architecture is not supported, existing distribution mechanisms such as
multicast, P2P and CDN can also be employed.

In other words, the content is recommended to be delivered through different connections simultaneously.
Based on the underlying distribution mechanisms, MSCD-FE may cooperate with related entities to fulfil
content delivery. For example, MSCD-FE may cooperate with MAS-F in the multi-connection environment. In
addition, MSCD-FE is recommended to coordinate the transmission of content over different connections,
according to connection related information, e.g., bandwidth, QoS, user preferences, etc. When the multi-
connection architecture is not supported, MSCD-FE may cooperate with the underlying P2P network to
distribute content from/to multiple peer nodes.
MSCD-FE is responsible to cache and store content and associated information.
MSCD-FE is recommended to interact with MAS-F to deliver content in coordination with the multi-
connection architecture. Thus, emphasizing, the multi-connection architecture is the preferred technology
to support MC-Streaming.
MSCD-FE can optionally support insertion, watermarking, transcoding and encryption pertaining to the
content.
Finally, MSCD-FE can optionally generate charging information.

8.4 Reference points
8.4.1 Reference point Ua

The Ua reference point exists between the MC-Streaming application control FE (MSAC-FE) and the MC-
Streaming application-user profile functional entity (MSUP-FE).
