Abstract

L'appareil de réception (100) selon l'invention décode, conformément à un procédé de décodage prédéterminé, des signaux vidéo et audio transmis dans une pluralité de couches, fournissant ainsi les signaux vidéo et audio. Dans cet appareil, une partie de réception (101) reçoit les signaux vidéo et audio, qui comprennent des signaux vidéo et audio de haute résolution transmis dans des couches pour lesquelles une voie de transmission fournit des influences importantes sur l'état de la réception, tout en comprenant également des signaux vidéo et audio de basse résolution transmis dans des couches pour lesquelles la voie de transmission fournit des faibles influences sur l'état de la réception. Une partie d'enregistrement (102) enregistre les signaux vidéo et audio reçus de basse résolution dans une mémoire. Une partie de détection (103) détecte l'état de la réception des signaux vidéo et audio reçus. Une partie de commande de commutation (104) commute, en fonction de l'état de la réception détecté, les signaux vidéo et audio devant être fournis par une partie de sortie (105) à partir des signaux vidéo et audio de haute résolution vers les signaux vidéo et audio enregistrés de basse résolution.
