Abstract

METODO Y DISPOSITIVO DE DECODIFICACION SON PROPUESTOS, PARA REDUCIR EL TIEMPO DE CONMUTACION DESDE UNA CANTIDAD DE FLUJOS DE BITS DE VIDEO DIGITAL DE ENTRADA QUE CORRESPONDE A N PROGRAMAS, PARA USARLOS BAJO LA SUPERVISION DE LOS MEDIOS DE CONTROL (30) QUE INCLUYEN UNA UNIDAD DE CONTROL (31) Y UN INTERRUPTOR (32), MIENTRAS UN FLUJO DE BITS DE VIDEO DIGITAL SELECCIONADO SE PRESENTA PARA DECODIFICARLO Y VISUALIZARLO, (N-1) MEMORIAS INTERMEDIAS (22,23) PARA LOS (N-1) FLUJOS DE BITS EXTRA, ESTAS MEMORIAS INTERMEDIAS EXTRAS ESTAN SIEMPRE DIMENSIONADAS DE MANERA QUE COMPRENDEN AL MENOS UN INTRA MARCO, Y PREFERIBLEMENTE EL MAS RECIENTE, DE CADA FLUJO DE BITS EXTRAS QUE LLEGAN. EN UNA SIMPLE PERSONIFICACION DONDE EL PROXIMO PROGRAMA CONMUTADO PARA ESTAR UNO ARRIBA, O UNO ABAJO, SOLO SON NECESARIAS UNA O DOS MEMORIAS INTERMEDIAS EXTRAS TANTO PARA EL CONOCIMIENTO DE LA INFORMACION COMO LOS PROGRAMAS DE ENTRADA PUEDEN SER ACCEDIDOS POR EJEMPLO, DE ACUERDO A ALGUNO ORDEN PREDEFINIDO. LA APLICACION: LOSEQUIPOS DE RECEPCION PARA DECODIFICAR LOS PROGRAMAS DE TELEVISION DIGITAL DE ACUERDO CON EL ESTANDAR DE MPEG.
