(EN) SYSTEM AND METHOD FOR STATISTICAL MULTIPLEXING OF VIDEO CHANNELS FOR DVB-H MOBILE TV APPLICATIONS
(FR) SYSTÈME ET PROCÉDÉ DE MULTIPLEXAGE STATISTIQUE DE CANAUX VIDÉO DESTINÉS À DES APPLICATIONS TV MOBILES DVB-H
Abrégé
(EN)
A DVB-H transmitter having a plurality of video encoders each having a variable bit rate associated with IP datagrams for each television program broadcast by one RF channel. A method is also provided for statistical multiplexing of video channels for DVB-H mobile TV applications, wherein the method includes jointly configuring a plurality of video encoders each having a variable bit rate associated with IP datagrams for each television program broadcast by one RF channel.
(FR)
L'invention concerne un émetteur DVB-H équipé de plusieurs codeurs vidéo ayant un débit binaire variable associé à des datagrammes IP pour chaque programme télévisé diffusé par un canal RF. L'invention concerne également un procédé de multiplexage de canaux vidéo destiné à des applications TV mobiles DVB-H, le procédé consistant à configurer simultanément plusieurs codeurs vidéo ayant un débit binaire variable associé à des datagrammes IP pour chaque programme diffusé par un canal RF.
