Abstract

Se realiza procesamiento de recepción de contenido de difusión, del cual se emplea un sistema de IP en transmisión. Una SDPT, en una parte de extensión de encabezado de la cual se dispone información de identificación de servicio y un SDP, en un SSC se transmite desde una estación de difusión. En un lado de recepción, se vuelve posible adquirir una SDPT pretendida del SSC de información de señalización fácilmente a una alta velocidad al realizar procesamiento de filtrado de sección con respecto a una corriente de transporte recibida. Después, es posible tener acceso a una corriente de un canal pretendido a alta velocidad basado en una dirección de IP y un número de puerto descrito en un SDP almacenado en una parte de extensión de encabezado de la SDPT adquirida.
