Abstract
In a distributed interactive multimedia service system, a client application of a set-top box located at a customer premises generates an attach request. A session manager, in response to receiving the attach request via a network, generates an allocation request and a create request. A resource manager, in response to the allocation request, allocates resources of a plurality of multimedia servers. The resources can include processor, memory, disk, and network resources. A media stream manager, in response to the create request, creates a multimedia stream. The session manager, in response to the resources being allocated, and the multimedia stream being created, launches a selected one of a plurality of multimedia services in the plurality of multimedia servers. The selected service provides multimedia information to the set-top box via the multimedia stream. The system includes a memory storing the plurality of multimedia services in a hierarchical tree structure having nodes representing composite and elemental services.
