Remote control device for controlling various functions of one or more appliances
First Claim
1. A remote control device for permitting a user thereof to control first and second appliances each having means for receiving information via a transmission channel, the first appliance additionally having a plurality of first appliance function controls which can be selectively actuated by the user to control the operation of the first appliance, with at least one of the first appliance function controls being an adjustable function control having a plurality of actuation states which can be selected to permit the user to select the manner in which the first appliance will execute the respective adjustable appliance function, the second appliance additionally having a plurality of second appliance function controls which can be selectively actuated by the user to control the operation of the second appliance, with at least one of the second appliance function controls being an adjustable function control having a plurality of actuation states which can be selected to permit the user to select the manner in which the appliance will execute the respective adjustable appliance function, said remote control device comprising:
- a plurality of manually actuated keys;
a plurality of electronic display elements, each display element corresponding to a respective key;
remote control means communicating with said keys and display elements for permitting the user to select either appliance and operate the appliance function controls of the selected appliance, said remote control means includingfirst means for assigning the first appliance to one key and displaying indicia identifying the first appliance on the respective display element, and for assigning the second appliance to another key and displaying indicia identifying the second appliance on the respective display element,second means for cancelling the assignment of the first means after the user has selected one of the appliances, and for thereafter assigning the appliance function controls of the selected appliance to respective keys and displaying indicia identifying these appliance function controls on the respective display elements, andthird means for cancelling the assignment of the second means if the user selects an adjustable function control, and for thereafter assigning the actuation states of the selected adjustable function control to respective keys and displaying indicia identifying these actuation states on the respective display elements; and
means operatively connected to the remote control means for generating coded signals and transmitting the signals over the transmision channel in response to manual actuation of the keys.

Abstract
A remote control unit, particularly for a television receiver or a video tape recorder, having a limited number of keys which have different functions that are identified by lettering presented on display elements corresponding to the keys, depending upon which appliance is selected for control. The remote control unit employs a microprocessor which cooperates with plug-in memories for the various appliances, the memories defining the key usages and corresponding lettering, etc. The remote control unit includes an additional display element for providing brief instructions to the user or displaying information received from the controlled appliance via a return channel.

10. A remote control device for permitting a user thereof to control predetermined functions of at least one appliance via a transmission channel, comprising:
-
a plurality of manually actuated keys; a plurality of electronic display elements, each display element corresponding to a respective key; control means communicating with asid keys and dispaly elements of assigning respective functions to the keys according to fixed rules applicable to the predetermined functions being controlled, and for displaying lettering identifying the assigned usages on the display elements corresponding to the keys; and means operatively connected to the control means for generating a coded signal and transmitting such signal over the transmission channel in response to manual actuation of said keys, wherein a requence having a predetermined number of may actuations is needed to control at least one of the predetermined functions and wherein the set of all possible sequences of the predetermined number of key actuations includes both sequences that are sufficient for controlling said at least one of the predetermined functions and sequences that are insufficient for controlling said at least one of the predetermined functions, and wherein said control means further comprises means for storing signals corresponding to key actuations and for permitting generation of said coded signal and transmission thereof over said transmission channel only if a sequence that is sufficient for controlling said at least one predetermined function has been completed.
