Session Supervisor System (S³)

Widespread and affordable broadband access opens up opportunities for delivery of new streaming services. The Future Internet of things and services is not envisaged to be simply a faster way to go online. What is expected to fundamentally change the way that people use the Internet is the ability to produce, and seamlessly deliver and share their own multimedia content. Market surveys and forecasts show that an increasing amount of consumers are interested on sharing music, pictures, and videos among digital electronics, PCs, and mobile devices. As a consequence, future home equipment will need to not only provide unique connectivity to the Internet and in the home, but also offer concurrent streaming multimedia sessions, adaptable to different personal preferences and network conditions. This added valued service is offered by the innovative Synelixis Session Supervisor System (S³).
Built as an OSGi bundle, the Supervisor S³ System is the solution offered by Synelixis to system manufacturers, telecom operators and service providers for personalized management, control and adaptation of multimedia sessions.

Session Management/Control

The S³ System provides for collection and handling of:

• - Streaming applications’ and services’ requirements

• - In-home network (WiFi, IEEE 802.16, Bluetooth, Zigbee) conditions and resources monitoring

• - User preferences/profiling and

• - Terminal Characteristics,

and controls the concurrent streaming multimedia sessions.
Either automatically or on user demand, the system is able to activate/deactivate sessions and modify the available characteristics (i.e. modulation, traffic bitrate, latency, scheduling algorithm, ARQ) may be selected and modified. of the associated connections based on the interface that is offered by the network equipment.

Content Adaptation

Apart from session control, S³ is able to control and initiate automatic adaptation of the streamed content based on network conditions and user preferences. For example, S³ is able to change the video codec, initiate transcoding and/or transrating of MPEG-2 and H.264 AVC video streams or modify parameter offered by the video streamer, the encoder and/or the transcoder/ transrater (e.g. Quantization Parameters, number of Macro-blocks per Slice, FEC etc.*

Customized Web Interface

Besides the integrated Graphical User Interface, the Session Supervisor System offers as add on, a servlet that provides the interface between the S³ back-end system and a web Application Programming Interface (API). Based on a simple and extendable open API, the customer may built his own customizable web based GUI to the S³ system.
Both bundles and the application are implemented utilizing the ECLIPSE programming environment and have been tested using the OSCAR OSGi JRE 1.4.2 and JRE 1.6 framework.
