Abstract
A centralized Digital Video Recording (DVR) and reproduction system links several reproduction and control units (such as television receivers, etc.) and a centralized server via a home area network. This allows programming to be distributed throughout the premises, and novelly allows live-pause recording and playback to be effected from more than one reproduction and control unit in a seamless manner. For example, during a live-pause episode, a viewer can pause a program from one control and reproduction unit, and resume viewing the program from the same pause point at another control and reproduction unit on the premises. The present invention also allows a viewer to view multiple programs from the server on the same monitor using a multiple picture-in-picture display.
