Title (EN) APPARATUS AND METHOD FOR TRANSFORMING TERRESTRIAL DMB STREAM, AND TERRESTRIAL DMB STREAM TRANSMITTING SYSTEM AND METHOD EMPLOYING THE SAME
(FR) DISPOSITIF ET PROCEDE DE TRANSFORMATION D'UN FLUX DE DIFFUSION MULTIMEDIA NUMERIQUE (DMB) TERRESTRE, SYSTEME DE TRANSMISSION DE FLUX DMB ET PROCEDE D'UTILISATION
Abstract:
(EN) The present invention provides an apparatus for transforming a terrestrial digital multimedia broadcasting (DMB) stream. The transformation apparatus includes a program specific information (PSI) extracting unit extracting PSI of a first stream and transmitting the first stream to a time code extracting unit a PSI analyzing unit analyzing the PSI of the first stream and acquiring construction information thereof; a PSI modifying unit for modifying the PSI information based on PSI modification information; the time code extracting unit for extracting time code information from the first stream based on stream information; a time code modifying unit for modifying a time code of a second stream based on the time code information; a stream erasing unit for erasing a stream piece of the first stream based on stream erasing information from the user; and a multiplexing unit for multiplexing the modified PSI, the modified first stream and the modified second stream.
(FR) La présente invention concerne un dispositif de transformation de flux de diffusion multimédia numérique (DMB). Le dispositif de transformation comprend les éléments suivants: une unité d'extraction d'informations spécifiques aux programmes (PSI) assurant l'extraction de PSI d'un premier flux et la transmission de ce premier flux à une unité d'extraction de code temporel; unité d'analyse des PSI qui analyse ces PSI pour un premier flux et en tire des informations d'élaboration; unité de modification de PSI utilisant des informations de modification appropriées; unité d'extraction de code temporel extrayant des informations de code temporel du premier flux sur la base d'informations de flux; unité de modification de code temporel modifiant le code temporel d'un second flux à partir d'informations de code temporel; unité d'effacement de flux assurant l'effacement d'une partie du premier flux à partir d'informations d'effacement émanant de l'utilisateur; et unité de multiplexage pour le multiplexage des PSI modifiées, du premier flux modifié et du second flux modifié.
