Abstract

En un proceso para controlar un descodificador digital de audio/video, se adquiere continuamente una corriente digital de audio/video (MPEG), cuya parte de video (MPEG video) esta constituida de una secuencia ordenada, de imagenes, se lleva a cabo una descodificacion (22) de video de todas las imagenes de la secuencia, y se genera una senal de video (CVSS) en base en unicamente parte de las imagenes de la secuencia (28) sin embargo, sin que se interrumpa la reproduccion de la secuencia de audio (Audio R, Audio L).
