4 Detailed service description
The service provided to an end-user is consumption of streaming multimedia. The end-user has a terminal that is able to
request a media stream, either from a built-in player, or an installed application. The terminal can be any terminal with
streaming media playing capabilities, and the service should allow a user to transfer between his terminals.
• The basic scenario is where an individual is browsing the Internet and finds some interesting content that
he/she wants to watch. The end-user is then either doing this through the operator’s portal or accesses the
content provider’s site. In the first case, the request is then processed through the portal, and charged as the
stream is set-up. In the second case, the content provider redirects the request to the operator, so that the
terminal capabilities can be collected and charging is done, before the stream is started.
• One scenario is an individual watching his favourite sports stream on his TV or PC at home, but he/she must
leave the house of some reason, and still wants to continue the session on his mobile terminal. In that case
he/she would transfer the ongoing session to the other terminal with other capabilities, since he already paid
for the entire episode.
• The other way is a similar case where an individual arrives at a destination with better viewing capabilities.
4.1 Overview
The figure below shows streaming content delivered to mobile terminals, but is not restricted to any particular terminal
type. The content is either on a location accessible over the Internet or stored locally on an operator's domain or the
content provider's domain. The access to the content is done through a smart router controlling the stream towards the
terminal. Transcoding of a stream is an optional feature that could allow users to switch between different terminal and
networks, while consuming content from a streaming source.

6.4 Controlling multiple streams
The following diagram illustrates the scenario where the content provider pauses an ongoing stream and temporarily
plays another stream, for example an advertisement. When the second stream ends the first original stream is continued.
From the end-user’s point of view this should be perceived as one uninterrupted stream.

6.6 Multimedia Stream Control with Dynamic QoS
The following sequence diagram provides an example of how an application could combine functionality from the
Multimedia Streaming Control web service (this specification) with the Application Driven QoS (ADQ) web service to
provide guaranteed media stream delivery.
Flow summary:
1. Content Provider receives a NotifyMediaStreamRequest which includes the content identifier, terminal
capabilities and an estimated available bandwidth of the current network session.
2. Based upon content requirements and current network bandwidth, the content provider may decide to provide
a guaranteed QoS for content delivery by applying a temporary QoS session (addTemporaryQoSFeature on
ADQ Web Service).
3. The content provider will then continue to setup the media stream through the StartMediaStream operation, as
for previous scenarios.
4. At some point during the ongoing stream, the network / terminal capabilities change and the content provider
is notified by the operator with the NotifySessionStatus operation.
5. Based on the new session parameters (e.g. available bandwidth), the content provider may modify the
guaranteed QoS parameters previously requested (modifyTemporaryQoSFeature).
6. Upon stream completion, content provider will remove the previously requested QoS session
(removeTemporaryQosFeature).

4 Detailed service description
The service provided to an end-user is consumption of streaming multimedia. The end-user has a terminal that is able to
request a media stream, either from a built-in player, or an installed application. The terminal can be any terminal with
streaming media playing capabilities, and the service should allow a user to transfer between his terminals.
• The basic scenario is where an individual is browsing the Internet and finds some interesting content that
he/she wants to watch. The end-user is then either doing this through the operator’s portal or accesses the
content provider’s site. In the first case, the request is then processed through the portal, and charged as the
stream is set-up. In the second case, the content provider redirects the request to the operator, so that the
terminal capabilities can be collected and charging is done, before the stream is started.
• One scenario is an individual watching his favourite sports stream on his TV or PC at home, but he/she must
leave the house of some reason, and still wants to continue the session on his mobile terminal. In that case
he/she would transfer the ongoing session to the other terminal with other capabilities, since he already paid
for the entire episode.
• The other way is a similar case where an individual arrives at a destination with better viewing capabilities.
4.1 Overview
The figure below shows streaming content delivered to mobile terminals, but is not restricted to any particular terminal
type. The content is either on a location accessible over the Internet or stored locally on an operator's domain or the
content provider's domain. The access to the content is done through a smart router controlling the stream towards the
terminal. Transcoding of a stream is an optional feature that could allow users to switch between different terminal and
networks, while consuming content from a streaming source.

6.4 Controlling multiple streams
The following diagram illustrates the scenario where the content provider pauses an ongoing stream and temporarily
plays another stream, for example an advertisement. When the second stream ends the first original stream is continued.
From the end-user’s point of view this should be perceived as one uninterrupted stream.

6.6 Multimedia Stream Control with Dynamic QoS
The following sequence diagram provides an example of how an application could combine functionality from the
Multimedia Streaming Control web service (this specification) with the Application Driven QoS (ADQ) web service to
provide guaranteed media stream delivery.
Flow summary:
1. Content Provider receives a NotifyMediaStreamRequest which includes the content identifier, terminal
capabilities and an estimated available bandwidth of the current network session.
2. Based upon content requirements and current network bandwidth, the content provider may decide to provide
a guaranteed QoS for content delivery by applying a temporary QoS session (addTemporaryQoSFeature on
ADQ Web Service).
3. The content provider will then continue to setup the media stream through the StartMediaStream operation, as
for previous scenarios.
4. At some point during the ongoing stream, the network / terminal capabilities change and the content provider
is notified by the operator with the NotifySessionStatus operation.
5. Based on the new session parameters (e.g. available bandwidth), the content provider may modify the
guaranteed QoS parameters previously requested (modifyTemporaryQoSFeature).
6. Upon stream completion, content provider will remove the previously requested QoS session
(removeTemporaryQosFeature).

4 Detailed service description
The service provided to an end-user is consumption of streaming multimedia. The end-user has a terminal that is able to
request a media stream, either from a built-in player, or an installed application. The terminal can be any terminal with
streaming media playing capabilities, and the service should allow a user to transfer between his terminals.
• The basic scenario is where an individual is browsing the Internet and finds some interesting content that
he/she wants to watch. The end-user is then either doing this through the operator’s portal or accesses the
content provider’s site. In the first case, the request is then processed through the portal, and charged as the
stream is set-up. In the second case, the content provider redirects the request to the operator, so that the
terminal capabilities can be collected and charging is done, before the stream is started.
• One scenario is an individual watching his favourite sports stream on his TV or PC at home, but he/she must
leave the house of some reason, and still wants to continue the session on his mobile terminal. In that case
he/she would transfer the ongoing session to the other terminal with other capabilities, since he already paid
for the entire episode.
• The other way is a similar case where an individual arrives at a destination with better viewing capabilities.
4.1 Overview
The figure below shows streaming content delivered to mobile terminals, but is not restricted to any particular terminal
type. The content is either on a location accessible over the Internet or stored locally on an operator's domain or the
content provider's domain. The access to the content is done through a smart router controlling the stream towards the
terminal. Transcoding of a stream is an optional feature that could allow users to switch between different terminal and
networks, while consuming content from a streaming source.

6.3 Trans-coding update
The following diagram illustrates the scenario where the capabilities for a terminal or a network changes, for example
due to handover between GPRS and 3G. The contents provider is notified about this change and can change for
example transcoding of the stream.

6.4 Controlling multiple streams
The following diagram illustrates the scenario where the content provider pauses an ongoing stream and temporarily
plays another stream, for example an advertisement. When the second stream ends the first original stream is continued.
From the end-user’s point of view this should be perceived as one uninterrupted stream.

6.5 Redirecting a stream
The following diagram illustrates the scenario where a stream is being redirected to another device due to a user
request. The contents provider receives the request from the end-user and continues the stream to the new device.

6.6 Multimedia Stream Control with Dynamic QoS
The following sequence diagram provides an example of how an application could combine functionality from the
Multimedia Streaming Control web service (this specification) with the Application Driven QoS (ADQ) web service to
provide guaranteed media stream delivery.
Flow summary:
1. Content Provider receives a NotifyMediaStreamRequest which includes the content identifier, terminal
capabilities and an estimated available bandwidth of the current network session.
2. Based upon content requirements and current network bandwidth, the content provider may decide to provide
a guaranteed QoS for content delivery by applying a temporary QoS session (addTemporaryQoSFeature on
ADQ Web Service).
3. The content provider will then continue to setup the media stream through the StartMediaStream operation, as
for previous scenarios.
4. At some point during the ongoing stream, the network / terminal capabilities change and the content provider
is notified by the operator with the NotifySessionStatus operation.
5. Based on the new session parameters (e.g. available bandwidth), the content provider may modify the
guaranteed QoS parameters previously requested (modifyTemporaryQoSFeature).
6. Upon stream completion, content provider will remove the previously requested QoS session
(removeTemporaryQosFeature).
