  • DAB digital audio broadcasting
  • a digital audio br adcasting (DAB) system having an enhanced reception in the movement state is one contrived approach.
  • DAB digital audio br adcasting
  • An initially developed DAB transmission system has been used mainly for the purpose of digitalizing an audio broadcasting and transmitting digitalized data at a low speed.
  • MPEG-2 moving picture experts group-2
  • MPEG-2 can be used to incorporate multimedia data encoded through diverse methods into the DAB transmission system. The use of MPEG-2 system is advantageous in multiplexing, synchronizing and transmitting multimedia data.
  • the DAB transmission system includes audio sources 101, audio encoders 102, an ensemble multiplexer 103, and an orthogonal frequency division multiplexing (OFDM) encoder 104. Since the conventional DAB transmission system is applied to digitalize an analog audio broadcasting, the conventional DAB transmission system is established mainly with focus of an audio broadcasting. In detail, the audio sources 101 are encoded' in the audio encoders 102 and are then transmitted through the OFDM encoder 104 by being multiplexed in the ensemble multiplexer 103. Although there is partially provided a low speed transmission of digital data, it is difficult to provide a multimedia service including real time moving pictures through the use of the conventional DAB transmission system.

  • the analyzed MPEG-2 stream is temporarily stored into an MPEG-2 TS buffering unit.
  • information necessary for configuring ETI frames is inputted by a system manager through the use of a GUI, and the analyzed information on configuration of the MPEG-2 stream is expressed. Also, the information necessary for configuring the ETI frames is implemented.
  • a required stream for configuring one ETI frame is read from the MPEG-2 TS buffering unit on the basis of the ETI frame configuration information. Then, the ETI frames are configured with use of the read stream.

Abstract

L'invention concerne un dispositif de conversion de flux multimédia et un procédé permettant d'obtenir un service multimédia dans un système de transmission par radiodiffusion numérique (DAB). Dans un premier temps, le flux de données multimédia fondé sur un système MPEG-2 est analysé de manière à transmettre des données multimédia selon la norme MPEG-2. Ensuite, au moyen des informations analysées, le flux de données multimédia est reconstitué sous forme de trames d'interface de transport d'ensembles (ETI) répondant à la norme de transport de trames ETI. Les trames ETI sont ensuite converties en un flux de données de radiodiffusion numérique (DAB), ce qui permet d'obtenir un service multimédia dans un système de transmission par radiodiffusion numérique (DAB).
