First Claim
1. Unit for remotely controlling a plurality of appliances each belonging to a one of a plurality of appliance categories, each having a model number signifying a given model of a given manufacture, each adapted to carry out a predetermined function upon receipt of a remote control signal having a predetermined format, comprising:
- transmitter means for transmitting remote control signals having formats corresponding to formatted command signals applied thereto;
first user-operable selector means for generating a first selector signal signifying the selected one of said plurality of model numbers;
second user-operable selector means for generating a second selector signal signifying the user-selected one of said appliance categories;
command display and select means for displaying user selectable commands associated with the selected one of said appliance categories, and for generating a command signal signifying one of said commands in response to user'"'"'s selection thereof;
means for generating an address signal in dependence on said first selector signal, said second selector signal and said command signal;
memory means storing a plurality of product and command tables in individually addressable storage locations;
and readout and formatting means for receiving said address signal and reading out product and command table data in said storage locations under control thereof, thereby creating read-out product and command data signals, formatting said command data signals in accordance with said product data signals, thereby creating said formatted command signals, and applying said formatted command signals to said transmitter means, whereby said transmitter means transmits a remote control signal having the correct format to control the user-selected appliance to perform the user-selected operation.

Abstract
The remote control unit has a selection mechanism for selecting any one of a number of categories of equipment to be controlled. The commands available for keyboard input in any given category are automatically displayed to the user upon selection of the category. Switches are provided for user selection of the model number of any one of a number of manufacturers of the equipment within the category to be controlled. Operation of the switches allows program controlled read-outs of formats stored in memory. An infra-red LED is then energized in accordance with the format to transmit the signal to the unit to be controlled.
