Title
(EN) METADATA TRANSLATION IN HDR DISTRIBUTION
(FR) TRADUCTION DE MÉTADONNÉES DANS UNE DISTRIBUTION À HDR
Abstract
(EN)
A method provides translation of metadata related to enhancement of a video signal according to a first high dynamic range video distribution type into metadata related to enhancement of a video signal according to a second high dynamic range video distribution type. Translation is done between a value of a first metadata set corresponding to a first type of high dynamic range video and a value of a second metadata set corresponding to a second type of high dynamic range video and uses an association that may be stored in a lookup table that is determined according to differences between a test image reconstructed using the metadata of first type and the same image reconstructed using the metadata of second type. A receiver apparatus and a transmitter apparatus comprising the translation method are also disclosed.

L'invention concerne un procédé assurant la traduction de métadonnées liées à l'accentuation d'un signal vidéo selon un premier type de distribution de vidéo à grande plage dynamique en métadonnées liées à l'accentuation d'un signal vidéo selon un second type de distribution de vidéo à grande plage dynamique. La traduction est effectuée entre une valeur d'un premier ensemble de métadonnées correspondant à un premier type de vidéo à grande plage dynamique et une valeur d'un second ensemble de métadonnées correspondant à un second type de vidéo à grande plage dynamique, et utilise une association qui peut être stockée dans une table de consultation qui est déterminée d'après des différences entre une image de test reconstituée à l'aide des métadonnées du premier type et la même image reconstituée à l'aide des métadonnées du second type. L'invention concerne également un appareil récepteur et un appareil émetteur comportant le procédé de traduction.
