ResumoA new three-channel audio matrix for use in multichannel sound television broadcasting is described. The proposed transmissions can be received by either a triphonic, biphonic, or monophonic receiver. The system utilizes two conventional stereophonic channels, plus a third channel which drives a center loudspeaker and which is used to subtract the center signal components from the left and right channels in a three-channel receiver. This eliminates the necessity for listeners to be positioned precisely halfway between the loudspeakers for optimum hearing conditions.
