Abstract
LOS DATOS DE VIDEO SE REPRODUCEN A PARTIR DE UN MEDIO DE GRABACION SOBRE EL CUAL ESTAN GRABADOS, DE FORMA MULTIPLEXADA, LOS DATOS DE VIDEO, DATOS DE TIEMPO DE REFERENCIA QUE REPRESENTAN UN TIEMPO DE REFERENCIA, Y DATOS DE TIEMPO DE VIDEO QUE REPRESENTAN EL TIEMPO EN EL CUAL SE INICIA LA DESCODIFICACION DE LOS DATOS DE VIDEO REPRODUCIDOS A PARTIR DEL MEDIO DE GRABACION. LOS DATOS DE TIEMPO DE REFERENCIA SE SEPARAN (5A) DE LOS DATOS MULTIPLEXADOS REPRODUCIDOS Y SE UTILIZAN PARA GENERAR DATOS DE SINCRONIZACION. LOS DATOS DE VIDEO Y LOS DATOS DE TIEMPO DE VIDEO SE ALMACENAN TEMPORALMENTE EN UNA MEMORIA INTERMEDIA DE VIDEO (6A) Y UN EXTRACTOR DE DATOS DE TIEMPO DE VIDEO (30) SE CONECTA A UNA SALIDA DE UNA MEMORIA INTERMEDIA DE VIDEO PARA EXTRAER LOS DATOS DE TIEMPO DE VIDEO DE LOS CONTENIDOS DE LA MEMORIA INTERMEDIA DE VIDEO. LA MEMORIA INTERMEDIA DE VIDEO (6A) TAMBIEN SE CONECTA A UN DESCODIFICADOR DE VIDEO (7) QUE DESCODIFICA LOS DATOS DE VIDEO TEMPORALMENTE ALMACENADOS EN LA MEMORIA INTERMEDIA DE VIDEO, EL FUNCIONAMIENTO DEL DESCODIFICADOR DE VIDEO ESTA CONTROLADO (31) COMO FUNCION DE UNA COMPARACION ENTRE LOS DATOS DE SINCRONIZACION GENERADOS Y LOS DATOS DE TIEMPO DE VIDEO EXTRAIDOS.
