A service platform for subscription-based live video streaming

The development and expansion of broadband technologies has stimulated the multimedia streaming market for the delivery of live streaming services which can be used for a variety of applications. The design of a generic audio and video streaming platform that can be employed for a wide range of applications is presented in this paper. A key feature of the platform is the `subscription framework´ which enables the service users to subscribe to a set of live feeds with their application specific requirements. The platform is capable of adjusting its service functionalities and the extent to which the media streams are secured for a particular user based on the requirements given at the service subscription. The platform is designed based on a layered architecture and a prototype implementation is carried out within the University network.
