A method for providing a start-over feature in a switched digital video system (100) that allows a user to watch a program from the beginning even through the user has tuned to the channel for the program after the program has begun, comprising: caching a copy of the program on a video server; providing an option to the user to watch the program after it has already begun at a rate that is faster than the real time rate of the program so that it will fit into a duration that is less than the originally scheduled duration for the program; determining the time remaining for the program; receiving a selection from the user of the option; and in response to receiving the selection by the user of the option, streaming the program to the user from its beginning at a rate that is faster than the real time rate of the program so that the viewing time of the stream is substantially the time remaining in the originally scheduled timeslot for the program. |
