Abstract
A bi-directional communications link between a television set and a remote control unit assists a viewer in controlling the entertainment system. The television set can signal the remote control unit to confirm instruction signal received from the remote control unit. The television can also transmit electronic program guide information to the remote control unit which is displayed on a display device on the remote control unit. The television can send the remote control unit a listing of available sub-channels within a single digital channel. The listing is displayed on the remote's display device, and the viewer can then choose from among the sub-channels.
