Abstract: A method and system for transmitting infra-red (IR) signals through power lines. An IR signal may be received and substituted with a corresponding RF signal. The RF signal may be placed on a power line network in one location and removed by a high-pass filter at a second location. The RF signal may be converted back to the corresponding IR signal.

Abstract: The present invention provides method and apparatus for transmitting stereo and surround sound information of the L-R signal without excessive attenuation at the higher frequencies in order to allow transmission of surround sound through a noisy medium. The apparatus includes an audio breakout matrix (20) coupled to receive a left (12) and a right (14) audio inputs; a surround sound conditioner (22) coupled to receive a L-R signal portion of the television signal for pre-emphasizing and companding the L-R signal to produce a conditioned L-R signal; a mixer (26) coupled to the surround sound conditioner for switching the conditioned L-R signal at a predetermined value to produce an amplitude modulated L-R signal; and a synchronizing circuitry (24, 29) coupled to the mixer for maintaining the predetermined value in step with the reference value, wherein the mixed L-R signal is combined with a L+R signal portion of the television signal to produce a composite output signal (18).
