5) MC-Streaming can optionally prevent unauthorized network topology discovery by itself, or rely on
other network elements' support.

7.2 MUE requirements

The MC-Streaming MUE:
1) Is required to support multiple network connections simultaneously, and it is recommended to
support more than one kind of access network.

2) Is recommended to support more than one kind of video and audio formats.
3) Is required to support subscriber authentication and identification management.
4) Is recommended to support synchronization and composition of media flows received from
different network connections.
5) Can optionally support user interaction, including programme selection, play, pause, fast forward,
rewind, recording, replay, etc.

6) Can optionally support user generated content to be uploaded and shared to other subscribers.
7) Can optionally support acquiring and collecting equipment capability by the network to provide
better service provisioning.
8) MC-Streaming is recommended to support various types of user equipment, e.g., mobile phone,
PDA, personal computer, pad, etc.

8 Architecture

8.1 General architecture
The architecture of MC-Streaming impacts all layers of the multi-connection architecture. Some new
functional entities are introduced into the application layer. Figure 8-1 provides an overview of the MC-
Streaming functional architecture.

The general architecture of MC-Streaming provides the following major functionality, it:
a) Receives MC-Streaming related requests from the MUE and provides user interaction capabilities.
b) Provides authentication and authorization for MC-Streaming.
c) Obtains original content from the content provider.
d) Pre-processes original content to make it appropriate to be transferred over access networks.

e) Delivers content to the MUE using network resources from multiple networks.
