Abstract
(EN)
Disclosed in the embodiments of the present application are a method and an apparatus for processing a high dynamic range (HDR) video including captions. The method comprises: encapsulating HDR video data into a video data frame matching a transmission interface; encapsulating caption information into a caption information frame matching the transmission interface; and transmitting, by means of the transmission interface, the video data frame and the caption information frame to a display device separately, the video data frame and the caption information frame being two kinds of data packet formats. The method provided in the present application transmits dynamic metadata HDR video content and caption information to a display device separately, so that the display device can obtain the separate video content and caption information, and then respectively process the HDR video and captions in a targeted way, improving the caption display effect of a dynamic metadata HDR video.

La présente invention concerne des modes de réalisation d'un procédé et d'un appareil permettant de traiter une vidéo à plage dynamique élevée (HDR) comprenant des sous-titres. Le procédé consiste à : encapsuler des données vidéo HDR dans une trame de données vidéo correspondant à une interface de transmission; encapsuler des informations de sous-titres dans une trame d'informations de sous-titres correspondant à l'interface de transmission; et transmettre, au moyen de l'interface de transmission, de la trame de données vidéo et de la trame d'informations de sous-titre à un dispositif d'affichage séparément, la trame de données vidéo et la trame d'informations de sous-titre étant deux types de formats de paquets de données. Le procédé selon la présente invention transmet des métadonnées dynamiques HDR de contenu vidéo et de sous-titre à un dispositif d'affichage séparément, de telle sorte que le dispositif d'affichage peut obtenir les informations de contenu vidéo et de légende séparées, puis traiter respectivement les vidéos et les sous-titres HDR d'une manière ciblée, améliorant l'effet d'affichage de sous-titres d'une vidéo HDR à métadonnées dynamiques.
