摘要： A technique for managing session setup for video on demand sessions involves caching information related to session setup for a session manager and then utilizing the cached information to setup a video on demand session for a client in response to a session setup request that is received from the client. Because information related to session setup is cached for the session manager, the session manager can utilize the information to establish a session without having to exchange messages with other video on demand elements, in particular other servers in the video on demand network. Reducing or eliminating the number of messages exchanged between video on demand elements enables video on demand sessions to be quickly and efficiently setup.

摘要： A technique for managing the streaming of digital video content involves providing a unicast stream to a client in response to the playout status of the unicast stream at the client. In particular, a unicast stream is provided to a client based on whether or not the unicast stream is intended for real-time playout at the client. In order to preserve valuable network resources, if the client does not intend the unicast stream for real-time playout, the unicast stream is not provided to the client. Network resources can also be conserved by utilizing one session between a stream server and a client to support more than one active unicast stream between the stream server and the client in the case where at least one of the active unicast streams is not intended for real-time playout at the client.
