Abstract
(EN) A video re-coding method for converting a first video signal (1) encoded in a first format into a second video signal (122) encoded in a second format, each said video signal comprising a series of video-signal elements (n), the method comprising steps of: storing a plurality of successive video-signal elements of the received first video signal as first-signal elements (104); decoding said first-signal elements (104) to produce corresponding intermediate video-signal elements (112) having a format different from each of said first and second formats, wherein at least two decoding processing threads are implemented to decode the first-signal elements (104) in a time-shared manner; storing the intermediate video-signal elements (112) produced by the at least two decoding processing threads; encoding said intermediate video-signal elements (112) to produce corresponding second-signal elements (116) having said second format, wherein at least two encoding processing threads are implemented to encode the intermediate video-signal elements in a time-shared manner; and storing the second-signal elements produced by the at least two processing threads.
(FR) L'invention concerne un procédé de recodage vidéo pour convertir un premier signal vidéo (1) encodé en un premier format en un second signal vidéo (122) encodé en un second format, chaque signal vidéo précité comprenant une série d'éléments de signal vidéo (n). Le procédé comprend les étapes consistant à : mémoriser une pluralité d'éléments de signal vidéo successifs du premier signal vidéo reçu en tant que premiers éléments de signal (104) ; décoder lesdits premiers éléments de signal (104) pour produire des éléments de signal vidéo intermédiaires correspondants (112) au format différent de chacun des premier et second formats précités, au moins deux unités d'exécution de traitement de décodage étant mises en œuvre pour décoder les premiers éléments de signal (104) d'une manière partagée dans le temps ; mémoriser les éléments de signal vidéo intermédiaires (112) produits par les deux unités d'exécution de traitement de décodage ; encoder les éléments de signal vidéo intermédiaires précités (112) pour produire des seconds éléments de signal correspondants (116) ayant le second format précité, au moins deux unités d'exécution de traitement d'encodage principales étant mises en œuvre pour encoder les éléments de signal vidéo intermédiaires d'une manière partagée dans le temps ; et mémoriser les seconds éléments de signal produits par les deux unités d'exécution de traitement.
