Abstract
A remote control system for a television receiver includes a transmitter and a receiver, the transmitter being adapted for transmitting a single word multibit code identifying a selected function of the television receiver. Each bit of the transmitted multibit code comprises a first occurring data signal representing a selected logic state followed immediately in time succession by a second occurring data signal representing the complementary logic state, the first and second data signals comprising a single pulse representing a first logic state or a grouping of at least two relatively closely spaced pulses representing a second logic state, whereby each transmitted bit comprises the same number of pulses. The remote control receiver includes apparatus for testing the parity relationship of the first and second occurring data signals of each bit of the received multibit code and for controlling the selected function in response to each tested bit being characterized by a condition of parity.
