    Abstract: Appareil de traitement de données (500) dans un système de radiodiffusion numérique. L'appareil de traitement de données (500) comprend un séparateur de trame (520) qui décode une première trame d'interface de transmission d'ensemble (trame ETI) et sépare des premières données de canal d'information rapide (données FIC) configurant une première trame ETI et des données qui ne sont pas des données FIC, un convertisseur de canal d'information rapide (530) qui convertit les premières données FIC en nouvelles secondes données FIC, et une unité de configuration de trame (540) qui configure une seconde trame ETI sur la base des secondes données FIC et des données qui ne sont pas des données FIC. Selon un mode de réalisation, seulement certaines informations du canal d'information rapide sont changées sans re-multiplexer l'interface de transmission d'ensemble et maintient la partie restante, minimisant le changement de la trameETI d'entrée et simplifiant son changement.

    Abstract: An apparatus for transmitting data in a digital broadcasting system is disclosed. The apparatus includes: a source encoding unit for encoding data to be transmitted and generating source-coded data; a capacity managing unit for dividing the source-coded data into divided data for a plurality of channels in case that an available data capacity for transmitting the source-coded data does not exist in one channel but sum of available data capacities of the multiple channels can accommodate the source-coded data, and adding header information to the divided data; a channel encoding unit for encoding the divided data according to channel environment and generating channel-coded data; and a transmitting unit for multiplexing, modulating and transmitting the channel-coded data through multiple frequency bands and multiple broadcasting sites.

    Abstract: Provided is a transmitting/receiving method and device for providing a conditional access broadcasting service. A transmitting method for providing a conditional access broadcasting service includes generating a control word (SI 10) for scrambling by- encoding a conditional access subscriber's, and changing the encoded data into an entitlement control message and an entitlement management message including the data generated by classifying the conditional access subscriber and a non-subscriber by activating the data (S120). Also, the method includes generating a final stream by multiplexing (S130) the entitlement control message, the entitlement management message, and a base stream for a first broadcasting service (SI 40), generating a base layer frame and an enhancement layer frame (SI 50) based on the final stream and an enhancement layer stream for a second broadcasting service, generating a broadcasting signal by hierarchically modulating (SI 60) the base layer frame and the enhancement layer frame, and transmitting the broadcasting signal.

    Abstract: The present invention relates to an on-channel repeating apparatus and method. An embodiment of the present invention provides an on-channel repeating method including: subtracting a replica of a feedback signal from a signal received from a main transmitter or another repeating apparatus; demodulating and equalizing the signal to remove noise, a multipath signal, and the remaining feedback signal from the signal; inserting identification signal having good correlation properties into the signal; modulating the signal; and transmitting the modulated signal. Another embodiment of the present invention provides an on-channel repeating apparatus including: a unit that converts signals received from a main transmitter or another repeating apparatus into signals in a predetermined band; a unit that generates identification signals having good correlation properties; a unit that generates a replica from the signals in the predetermined band and the identification signal, and then removes a feedback signal; a unit that demodulates a signal from which the feedback signal is removed; a unit that equalizes the demodulated signal to remove noise, a multipath signal, and the remaining feedback signal therefrom; a unit that inserts the identification signal into the equalized signal; and a unit that modulates the signal having the identification signal inserted thereinto and transmits the modulated signal. According to the present invention, the repeating apparatus repeats output signals that have a small time delay and whose distortion is corrected. Therefore, it is possible to improve the utilization of limited frequency sources, and reduce investment in achieving a repeating apparatus.
