(EN) HIGH DYNAMIC RANGE VIDEO CODING ARCHITECTURES WITH MULTIPLE OPERATING MODES
(FR) ARCHITECTURES DE CODAGE VIDÉO DE PLAGE DYNAMIQUE ÉLEVÉE AYANT DE MULTIPLES MODES DE FONCTIONNEMENT
Abstract
(EN)
A high dynamic range (HDR) signal processing device may receive a video signal and an operating mode indication. The operating mode indication may indicate a format of the video signal, for example, an HDR format or a non-HDR format. Whether to perform adaptive reshaping on the video signal may be determined based on the operating mode indication. For example, it may be determined to perform the adaptive reshaping if the operating mode indicates that the video signal is in an HDR format. It may be determined to bypass the adaptive reshaping if the operating mode indicates that the video signal is in the non-HDR format. Multiple types of HDR reconstruction metadata may be received via a network abstraction layer (NAL) unit.

Selon l'invention, un dispositif de traitement de signal de plage dynamique élevée (HDR) peut recevoir un signal vidéo et une indication de mode de fonctionnement. L'indication de mode de fonctionnement peut indiquer un format du signal vidéo, par exemple, un format HDR ou un format non HDR. Le point de savoir s'il faut ou non réaliser une remise en forme adaptative sur le signal vidéo peut être déterminé sur la base de l'indication de mode de fonctionnement. Par exemple, il peut être déterminé de réaliser la remise en forme adaptative si le mode de fonctionnement indique que le signal vidéo est dans un format HDR. Il peut être déterminé de contourner la remise en forme adaptative si le mode de fonctionnement indique que le signal vidéo est dans le format non HDR. De multiples types de métadonnées de reconstruction HDR peuvent être reçus par l'intermédiaire d'une unité de couche d'attraction de réseau (NAL).
