Abstract

En un aparato multiplexor emisor digital para rnultiplexar una pluralidad de programas en un unico canal físico, a fin de emitir el programa emisor digital multiplexado. se provee un aparato para corregir las posiciones de los paquetes de PCR contenidos en corrientes de transpone dentro de los respectivos programas, y un aparato formador de valores de correccion de PCR para aplicar valores de correccion de PCR respecto de un resultado de las correcciones de posicion a fin de ejecutar simplemente una funcion capaz de sincronizar de manera uniforme los paquetes de PCR contenidos en las corrientes de transporte y capaz de visualizar los programas recibidos sin ninguna interrupcion en el lado receptor, incluso cuando se realiza una operacion de ajuste. Entonces, el aparato multiplexor emisor digital emite una corriente emisora de paquete de programas que ha sido multiplexada como programa emisor unico de manera tal que los paquetes de PCR se sincronizan entre sí entre la pluralidad de programas.
