Title (EN) URGENT PACKET TRANSMISSION/RECEPTION APPARATUS AND METHOD FOR DIGITAL BROADCAST SYSTEM
(FR) APPAREIL ET PROCÉDÉ D'ÉMISSION/RÉCEPTION DE PAQUET URGENT POUR UN SYSTÈME DE DIFFUSION GÉNÉRALE NUMÉRIQUE
Abstract:
(EN) An apparatus and method for transmitting/receiving an urgent packet in a digital broadcast system is provided. A packet transmission apparatus of a digital broadcast transmitter includes a buffer which buffers broadcast packets; an urgent packet generator which generates an urgent packet having an urgent packet header indicating the urgent packet when a packet containing urgent data is detected; and a frame generator which generates a frame with the broadcast packets and inserts the urgent packet into the frame, wherein the urgent packet is substituted for one of broadcast packets in the frame.
(FR) Cette invention se rapporte à un appareil et à un procédé destinés à émettre/recevoir un paquet urgent dans un système de diffusion générale numérique. Un appareil d'émission de paquet d'un émetteur de diffusion générale numérique comprend une mémoire tampon qui tamponne des paquets de diffusion générale; un générateur de paquet urgent qui génère un paquet urgent qui présente un en-tête de paquet urgent qui indique que le paquet est urgent lors de la détection d'un paquet qui contient des données urgentes; et un générateur de trame qui génère une trame avec les paquets de diffusion générale et insère le paquet urgent dans la trame, le paquet urgent remplaçant l'un des paquets de diffusion générale dans la trame.
