Abstract
A system for the delivery of video on demand (VOD). A wireless remote control device generates keystroke signals for controlling a TV display and has a single button for restarting a selected program at a beginning of the selected program. A head-end unit supports separate downstream virtual channels for each separate TV set connected on a common TV feeder-cable; The head-end unit locally records and stores many programs, and transmits each program using a compressed digital format. The Compressed digital format may use MPEG-2 or MPEG-4. The head-end unit has means for protecting against signal theft. A set top unit encapsulates the keystroke signals and transmits the keystroke signals via a two-way channel to the head-end unit.
