For offering entertainment services by video streaming content to users, a video encoder creates the required .nsc file for each broadcast channel. This .nsc file is retrieved and stored on a server which notifies each set-top box in the field, via a multicast notifier of the availability of the new service. This notifier contains the multicast address and port to where the .nsc files are being streamed. Once the set-top box retrieves this notification, it attempts to join the dedicated multicast stream, download the .nsc files and store them locally in memory on the set-top box. When a user selects a broadcast channel from their lineup, the set-top box will access the local file to obtain the proper information about that particular ASF stream; hence, it will not have to do an HTTP retrieval.
