Abstract

A digital video recorder (DVR) for use with a monitor and a set top box (STB) is disclosed. The STB demodulates program data from a program signal received over a communication channel and generates a STB graphical user interface (GUI). The DVR comprises a local memory for storing the program data received from the STB, a DVR interface for communicating with the STB, and a DVR controller. The DVR controller generates a DVR GUI, and in response to user input, communicates with the STB to coordinate whether the STB GUI or the DVR GUI is displayed on the monitor.
