CA 2697459

A digital broadcasting system and a data processing method are disclosed. The data processing method includes receiving a broadcast signal in which main service data and mobile service data are multiplexed, demodulating the broadcast signal to acquire fast-information-channel signaling information including reference time information for a system clock, and outputting demodulation time information of a specific position of a frame of the broadcast signal, decoding the fast-information-channel signaling information, and establishing the reference time information as the system clock at a demodulation time according to on the outputted demodulation time information and decoding the mobile service data according to the system clock.

L'invention concerne un système de diffusion numérique et un procédé de traitement de données. Le procédé de traitement de données consiste à recevoir un signal de diffusion dans lequel des données de service principales et des données de service mobiles sont multiplexées, démoduler le signal de diffusion pour acquérir des informations de signalisation d'un canal d'informations rapide comprenant des informations de temps de référence pour l'horloge d'un système, et fournir des informations de temps de démodulation d'une position spécifique d'une trame du signal de diffusion, décoder les informations de signalisation du canal d'informations rapide, et établir les informations de temps de référence en tant qu'horloge du système à un moment de démodulation en fonction des informations de temps de démodulation fournies et décoder les données de service mobiles en fonction de l'horloge du système.
