Abstract
(EN)
A video encoder generates an encoded video bitstream comprising a plurality of layers. At least one access unit of the encoded video bitstream includes one or more Instantaneous Decoding Refresh (IDR) pictures and one or more non-IDR pictures. The IDR pictures include only slices that are decoded using intra prediction only. The video encoder outputs the encoded video bitstream. A video decoder decodes the encoded video bitstream.

Selon l'invention, un codeur vidéo génère un flux binaire vidéo codé comprenant une pluralité de couches. Au moins une unité d'accès du flux binaire vidéo codé comprend une ou plusieurs images de rafraîchissement de décodage instantané (IDR) et une ou plusieurs images non IDR. Les images IDR comprennent seulement des tranches qui sont décodées à l'aide d'une prédiction intra seulement. Le codeur vidéo délivre le flux binaire vidéo codé. Un décodeur vidéo décode le flux binaire vidéo codé.
