Abstract
A method of transmitting at least one sound signal within the frequency spectrum of a video signal in which, at the transmitting end, the sound signal accompanying a frame duration of the image signal is stored in the that this frame lasts in a storage device and is transmitted after the duration of this frame, during the line sweep of one of the lines free for the image retraction following this frame, and in which the content of the signal The sound of this line is stored in the receiver in a storage device, and it is retransmitted to the sound section of the receiver within the period of the following table, characterized in that in the receiving end the momentary values of the sound signal to the beat of a high timing generator or pulse repetition rate and carried to storage capacitors, and by which the auxiliary oscillator qu e is used for the generation of the repetition pulse frequency or high timing generator is synchronized by an alternating current voltage or a signal that is transmitted in a line of the vertical white interval that proceeds to the lines with the content of the signal of sound, with the duration of the period of said signal corresponding to a multiple of the product of half the line period and the time compression factor as used at the transmitting end, given by the ratio of the line transmission time of the sound signal for the duration of the frame period.
