Abstract

Un sistema de video que procesa una corriente de bitios, que incluye una longitud variable de prioridad elevada o baja de palabras de Datos codificados. El Dato codificado y un Dato de baja prioridad (145) empacado por medio de unidades respectivas de empacado de datos. El Dato codificado se aplica continuamente a ambas unidades de empacado. Las palabras de Longitud de Ata Prioridad y de Baja Prioridad, que indican la longitud de bitio de los componentes de alta prioridad y de baja prioridad del Dato Codificado, se aplican (114, 116) a los empacadores de datos de alta prioridad y de baja prioridad, respectivamente. La palabra de Longitud de Baja Prioridad, se lleva a cero cuando el Dato de alta prioridad se va a empacar para transportarse a través de una primera trayectoria de salida, y la palabra de longitud de alta prioridad se lleva a cero cuando el Dato de baja prioridad se va a empacar para transportarse a través de una segunda trayectoria de salida.
