ABSTRACT:
A full function remote control pillow speaker arrangement is coupled by three wires to a television receiver. The arrangement includes a standard IR control signal encoder, the output of which is filtered to remove the 40 kilohertz ultrasonic frequency, thus yielding an envelope corresponding to the data pulses. Operating power is supplied to the encoder from a DATA line and a common (COM) line with a shunt regulator being interposed to protect the encoder from over voltage conditions during standby operations. A speaker is supplied audio signals from the (COM) line and an audio line. The receiver is capable of functioning with other types of pillow speaker control units, i.e. those having a single key closure for channel and on/off control and those with extra key closures for channel directional control. A circuit is included that discriminates between data pulses and key closures for transmitting data pulses to the television receiver IR data processing circuitry and transmitting key closures to receiver key scan processing circuitry.
