Abstract
A digital video recorder (DVR) for use with a monitor and a set top box (STB) is disclosed. The STB demodulates program data by tuning to at least one of a plurality of channels and comprises a DVR interface. The DVR comprises a local memory for storing the program data received from the STB, and a STB interface for communicating with the DVR interface. The DVR further comprises a DVR controller for communicating control data to direct the STB to tune to a selected channel, and for receiving a channel-change event from the STB in connection with the STB changing the tuned channel.
