Abstract

A method of transmitting at least one sound signal within the frequency spectrum of a video signal, characterized in that at the transmitting end the sound signal accompanying a frame of the image signal is stored during this frame in a storage device, and is transmitted after the duration of this frame, during the line sweep of one of the free lines for the recoil of the beam that follows this frame, and because the content of the sound signal of this line it is stored in the receiver on a storage device and retransmitted to the receiver's sound section within the subsequent frame period.
