  • Patent number: 5410326
    Abstract: A universal remote control device which is programmed to operate a variety of consumer products is disclosed. The device is connected over a bidirectional link to either a cable converter or a telephone interface for receiving programming information. A touch screen display is employed on the programmable remote control device for displaying icons of functions to be selected. By selecting a particular displayed icon, a command can be decoded and sent via an infrared link to one or more appliances. Infrared codes for operating a virtually unlimited number of devices can be supplied to the device over the bidirectional communications link. Further, a provision is provided to permit a telephone connection to be set up between the user's home and a facility advertising products or services over a cable television broadcast. The touch screen display will permit the actual display of these advertisements as messages received from the cable head end system.
