Title
(EN) SIGNALING OF PICTURE HEADER IN VIDEO CODING
(FR) SIGNALISATION D'EN-TÊTE D'IMAGE DANS UN CODAGE VIDÉO
Abstract
(EN)
A method of decoding is provided. The method includes receiving a video bitstream including a picture unit (PU), where the PU includes a picture header (PH) network abstraction layer (NAL) unit preceding a first video coding layer (VCL) NAL unit, and decoding a coded picture from the PU to obtain a decoded picture.
(FR)
L'invention concerne un procédé de décodage. Le procédé comprend la réception d'un flux de données vidéo comprenant une unité d'image (PU), la PU comprenant une unité de couche d'abstraction de réseau (NAL) d'en-tête d'image (PH) précédant une première unité NAL de couche de codage vidéo (VCL), et le décodage d'une image codée à partir de la PU pour obtenir une image décodée.
