The figures 01 and 02 shows the basic entities involved in the Streaming service and how they connect.
Clients initiate the service and connect to the selected content server. Content servers can generate live content e.g. video from a concert. User profile and terminal capability data can be stored on a network server and will be contacted at the initial set up. User Profile will provide the Streaming service with the user’s preferences. Terminal capabilities will be used by the Streaming service to decide whether or not the client is capable of receiving the streamed content.
Portals are servers allowing convenient access to streamed media content. For instance, a portal might offer content browse and search facilities. In the simplest case, it is simply a Web/WAP-page with a list of links to streaming content. The content itself is usually stored on content servers, which can be located elsewhere in the network.
