Abstract
In an exemplary broadband video distribution network, an edge interface device at the customer premises detects a condition relating to an interruption of video service, e.g. a power outage at the premises. The interface device notifies the network, to allow identification of the point of interruption and the program being viewed. Upon resumption of service, the network offers to provide a replay of the program, starting from a point substantially corresponding to the point of interruption. If the program was pre-recorded (e.g. from a VOD server) or was automatically recorded in the network as part of another service, the replay is provided as a narrowcast transmission from the appropriate source starting at about the point of interruption. If the viewer was watching a broadcast program not otherwise recorded, it may also be necessary to activate recording of the program in a network video recorder, in response to the interruption.
