A broadcast system and method that includes a video content network that connects a video server, a discovery server, a switched digital video service, a switched video manager, and a set-top box. The set-top box receives and stores an assigned location identifier, and receives a mapping from the discovery server, where the mapping includes records, each record associating a location identifier and a service group. The set-top box matches the assigned location identifier to the mapping to determine an assigned service group for the set-top box. The set-top box receives an address from the discovery server that identifies the switched video manager that is associated with the assigned service group. The set-top box operates in the broadcast system by communicating with the switched digital video service, and the switched video manager.
