| Prise en charge des espaces chromatiques |
 |
Le présent amendement permet d'indiquer les caractéristiques de transfert employées des systèmes à palette de couleurs étendue de la Rec. UIT-R BT.1361 et de la CEI 61966-2-4 dans les flux binaires vidéo codés selon la Rec. UIT-T H.262 | ISO/CEI 13818-2 (officieusement connue sous le nom de norme MPEG-2 vidéo). Il permet aussi de mieux harmoniser la prise en charge des espaces chromatiques avec des indicateurs semblables, définis dans les amendements des normes de codage vidéo de la Rec. UIT-T H.264 | ISO/CEI 14496-10 et ISO/CEI 13818-2, tout en ajoutant la prise en charge d'un indicateur des coefficients matriciels "YCgCo", comme défini précédemment dans la Rec. UIT-T H.264 | ISO/CEI 14496-10. En outre, il permet d'améliorer et de mettre à jour du point de vue rédactionnel les parties de la norme qui concernent les indicateurs des espaces chromatiques vidéo. |
