Abstract
Abstract In a remote control system, for example for the adjustment of a television set or a radio set, at least one portion of the commands to be transmitted is determined by an analog setting. To this end, the transmitter is selectively operated to transmit a binary code word characterizing the command and analog information is provided by adjusting the time interval between the code word and the next following code word. The second code word may be identical to the first code word, in which case the code word is repeated at selected intervals. The second code word could also be an individual pulse. The receiving system includes a decoder for identifying the command and an analog sensing circuit for terminating the command in response to the adjusted time interval between code words.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
178 words
A remote control system for controlling a plurality of controlled devices, comprising: a transmitting system for transmitting digital command code words identifying the controlled devices to be activated and analog information defining the degree of activation, said transmitter system including a code word generator operable to produce a digital code word followed by a digital signal, selection and activation means connected to said code word generator and operable to select the code words, the time interval between the code word and the digital signal and to activate said code word generator, and transmitting means connected to said code word generator for receiving and transmitting the digital and analog signals; and a receiving system for providing corresponding execution signals in response to the digital and analog signals, said receiving system including receiving means for receiving the digital and analog signals, decoding means connected to said receiving means for decoding the code words and providing a corresponding execution command, and analog sensing means connected to said receiving means and operable to produce a signal to terminate execution of the command.
Claim 2
Dependent Claim
178 words
A remote control system for controlling a plurality of controlled devices, comprising: a transmitting system for transmitting digital command code words identifying the controlled devices to be activated and analog information defining the degree of activation, said transmitter system including a code word generator operable to produce a digital code word followed by a digital signal, selection and activation means connected to said code word generator and operable to select the code words, the time interval between the code word and the digital signal and to activate said code word generator, and transmitting means connected to said code word generator for receiving and transmitting the digital and analog signals; and a receiving system for providing corresponding execution signals in response to the digital and analog signals, said receiving system including receiving means for receiving the digital and analog signals, decoding means connected to said receiving means for decoding the code words and providing a corresponding execution command, and analog sensing means connected to said receiving means and operable to produce a signal to terminate execution of the command.
Claim 3
Dependent Claim
28 words
