Abstract
PROCEDIMIENTO DE TRANSMISION SIMULTANEA DE DATOS NUMERICOS Y DE UNA SEÑAL VIDEO DE TELEVISION DE MULTIPLEXADO ANALOGICO DE LAS COMPONENTES LUMINANCIA Y CROMANCIA ASOCIADO A DATOS NUMERICOS QUE REPRESENTAN UN SONIDO ESTEREOFONICO Y DATOS AUXILIARES. CONSISTE EN TRANSMITIR UNA SEÑAL DE VIDEO DE LINEA QUE IMPLICA UN INTERVALO DE TIEMPO DE SUPRESION DE LINEA (A) CON UN IMPULSO DE SINCRONIZACION (D) SEGUIDO DE UNA MESETA O GRADO DE REFERENCIA DEL NEGRO (F), Y UNA PARTE UTIL DE LINEA (B) QUE COMPRENDE, FUERA DE LOS INTERVALOS DE TIEMPO DE SUPRESION DE TRAMA, UN MULTIPLEXADO DE DISTRIBUCION EN EL TIEMPO DE LAS COMPONENTES CROMINANCIA (G) Y LUMINANCIA (K) COMPRIMIDAS EN EL TIEMPO, Y DE UNA SALVA DE DATOS (H), QUEDANDO LA COMPONENTE LUMINANCIA (K) COMPRIMIDA EN UNA RELACION DE TRES Y MEDIO Y LA COMPONENTE CROMINANCIA (G) EN UNA RELACION SUPERIOR A TRES, VENTAJOSAMENTE SEIS PARA LIBERAR UN ESPACIO TEMPORAL PARALA SALVA DE DATOS (H) QUE TRANSMITE EL SONIDO ESTEREOFONICO Y DATOS AUXILIARES.
