Abstract

A digital video recorder (DVR) is disclosed for use with a monitor and a set top box (STB), the STB for demodulating program data from a program signal received over a communication channel and for generating a STB graphical user interface (GUI). The DVR comprises a local memory for storing the program data received from the STB and a plurality of program identifiers. The DVR further comprises a DVR controller for maintaining the plurality of program identifiers, and for communicating to the STB the plurality of program identifiers independent of when the STB demodulates the program data identified by the program identifiers. The STB is responsive to the plurality of program identifiers to modify at least one selected operation of the STB.
