A set-back box (SBB) includes a digital TV signal receiver. The SBB can be connected via a HDMI cable to a TV having only an analog TV signal receiver so that digital TV signals from the SUB can be displayed on the TV screen. The TV processor recognizes the SUB and in effect treats the digital receiver of the SBB as its own, such that a single remote control can be used to control both analog channel selection within the TV and digital channel selection within the SBB.
