Abstract

L'invention concerne un codeur de vidéo comportant : un module de génération de segments (202) agencé pour générer une première séquence de segments de vidéo (SEQ(1)) sur la base d'un premier flux de vidéo (EVS(1)) codé à un premier débit binaire et une deuxième séquence de segments de vidéo (SEQ(2)) sur la base d'un deuxième flux de vidéo (EVS(2)) codé à un deuxième débit binaire différent du premier débit binaire ; et un module de transmission de segments (204) agencé pour : recevoir, à partir d'un décodeur de vidéo, un signal de requête de segment (REQ) identifiant un segment de vidéo (SEG) sélectionné de la première ou de la deuxième séquence de segments ; générer du code de correction d'erreur directe pour le segment de vidéo sélectionné ; et transmettre le segment de vidéo sélectionné et le code de correction d'erreur directe généré.The invention relates to a video encoder comprising: a segment generation module (202) arranged to generate a first sequence of video segments (SEQ (1)) on the basis of a first video stream (EVS (1) ) encoded at a first bit rate and a second sequence of video segments (SEQ (2)) based on a second video stream (EVS (2)) encoded at a second bit rate different from the first bit rate; and a segment transmission module (204) arranged to: receive, from a video decoder, a segment request signal (REQ) identifying a selected video segment (SEG) of the first or the second sequence segments; generating direct error correction code for the selected video segment; and transmitting the selected video segment and the generated direct error correction code.
