Abstract

La presente invencion se refiere a un sistema para incluir datos de audio dentro de una señal de video. Se reduce el numero de cuadros de datos de video transmitidos, permitiendo de esta manera mayor tiempo por cada cuadro individual, permitiendo de esta manera que el pasaje protegido de cada línea de cada cuadro se alargue. El pasaje protegido reside entre el pulso de sincronizacion horizontal para la línea, y la señal ráfaga de color. Muestras de audio digitalizadas se colocan de los pasos protegidos.
