1 Core network aspects

2) MC-Streaming is recommended to support different media types (e.g., audio and video) as well as
formats (e.g., [ITU-T G.722]) to be delivered from a single source to one or multiple destinations/UE.
3) MC-Streaming is recommended to support the delivery of multimedia content throughout different
connections simultaneously, especially when multi-connection capability is supported by underlying
network elements and accesses.

4) MC-Streaming can optionally support multiple kinds of coding resolutions and aspects ratios
(e.g., ITU-T H.264 video compression).

5) MC-Streaming can optionally support live and/or video on-demand (VoD) content offering.
6) MC-Streaming can optionally support content or programme selection.
7) MC-Streaming can optionally support integration with other telecommunication services
(e.g., instant message, presence, telephony, etc.).
8) Multimedia content can optionally be transmitted to a single destination (e.g., VoD), or to multiple
destinations simultaneously (e.g., broadcasting service).

6.2.2 Interaction requirement
1) User interaction is recommended to be supported. Service provider and subscriber of MC-Streaming
can share interesting information within or between them, including programme information,
image, data, text, audio, etc.
2) MC-Streaming can optionally support interactive capabilities such as educational applications,
entertainment applications (e.g., games), communication services (e.g., mail, chat and messaging),
and information services (e.g., stock and weather services).
3) MC-Streaming can optionally support user generated content to be uploaded and shared to other
subscribers.
4) MC-Streaming can optionally support download of user generated content.
5) MC-Streaming can optionally support mechanisms for users to send user preferences to the server
during a streaming session, so that the service providers may offer personalized content markers to
the users.
6) MC-Streaming can optionally enable a subscriber to share content marker(s) with other subscribers
in accordance to legal aspects and operator policies.
7) MC-Streaming can optionally support content pushing by the service provider to the UE, which can
be requested or not requested by subscriber.
8) MC-Streaming can optionally support content filtering mechanisms so that a subscriber can filter
unwanted content.

6.3 QoS/QoE requirements
The requirements of quality of service (QoS) and quality of experience (QoE) are listed below:
1) MC-Streaming is recommended to support a subscriber's required level of QoS/QoE, security and
reliability.
2) MC-Streaming is recommended to support service continuity (i.e., seamless connection handover).
3) MC-Streaming is recommended to support service control to provide a quality at least as good as
the quality of any individual access technology under its control.
4) MC-Streaming is recommended to allow the delivery of MC-Streaming services with a subscriber's
defined quality of experience (QoE).
5) MC-Streaming can optionally support mechanisms to monitor audio and video quality.
6) MC-Streaming can optionally support consistent QoS.
7) MC-Streaming can optionally support mechanisms for QoE/QoS parameters adjustment due to the
changes of content characteristics in a connection.
