Abstract
(EN) A method of processing video data. The method includes using coded information during application of a super resolution (SR) process to a video unit; and performing a conversion between a video comprising the video unit and a bitstream of the video based on the SR process as applied using the coded information. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.
(FR) L'invention divulgue un procédé de traitement de données vidéo. Le procédé consiste à utiliser des informations codées pendant l'application d'un processus de super-résolution (SR) à une unité vidéo ; et réaliser une conversion entre une vidéo comprenant l'unité vidéo et un flux binaire de la vidéo sur la base du processus SR tel qu'appliqué à l'aide des informations codées. Un appareil de codage vidéo correspondant et un support d'enregistrement non transitoire lisible par ordinateur sont également divulgués.
