Abstract

Ce procédé sert à la transmission et à la diffusion par le réseau terrestre de télédiffusion d'un signal vidéo de télévision à multiplexage analogique des composantes luminance et chrominance associé à des données numériques représentant un son stéréophonique et des données auxiliaires. Il consiste à transmettre un signal vidéo de ligne comportant un intervalle de temps de suppression ligne a avec une impulsion de synchronisation d suivie d'un palier de référence du noir f, et une partie utile de ligne b comportant, en dehors des intervalles de temps de suppression trame, un multiplexage à répartition dans le temps des composantes chrominance g et luminance k compressées dans le temps, et d'une salve de données h, la composante luminance k étant compressée dans un rapport trois demi et la composante chrominance g dans un rapport supérieur à trois, avantageusement six pour dégager un espace temporel pour la salve de données h transmettant le son stéréophonique et des données auxiliaires.This method is used for the transmission and the broadcasting by the terrestrial television broadcasting network of an analog multiplexed television video signal of the luminance and chrominance components associated with digital data representing a stereophonic sound and auxiliary data. It consists in transmitting a line video signal comprising a line suppression time interval a with a synchronization pulse d followed by a reference black level f, and a useful part of line b comprising, outside the time intervals frame suppression, time-division multiplexing of the time-compressed chrominance g and luminance k components, and a data burst h, the luminance k component being compressed in a three-half ratio and the chrominance g component in a ratio greater than three, advantageously six to free up time space for the data burst h transmitting the stereophonic sound and auxiliary data.
