Abstract
A remote control system for a television receiver includes a transmitter and a receiver, the transmitter being adapted for transmitting a multibit code identifying a selected function of the television receiver wherein the data bits forming the multibit code each comprise a single pulse representing a first logic state and a grouping of at least two relatively closely spaced pulses representing a second logic state. The remote control receiver includes a self-clocking detector for converting the transmitted pulses to a binary logic signal and decoding means responsive to the logic signal for operating the selected television receiver function.
