Title (EN) A FRAMEWORK FOR QUALITY-AWARE VIDEO OPTIMIZATION
(FR) CADRE PERMETTANT UNE OPTIMISATION VIDÉO EN FONCTION DE LA QUALITÉ
Abstract:
(EN) A computer-implemented method includes receiving an encoded video frame, decompressing the received encoded video frame, extracting a first quantization parameter (QP) from the decompressed video frame, and acquiring a delta QP based on the first QP. The method also includes acquiring a second QP based on the delta QP and the first QP, compressing the decompressed video frame based on the second QP, and providing the compressed video frame. The first QP corresponds to quantization settings originally used for compressing the encoded video frame. And the second QP corresponds to quantization settings for compressing the decompressed video frame.
(FR) La présente invention se rapporte à un procédé informatique qui consiste à : recevoir une trame vidéo codée, décompresser la trame vidéo codée reçue, extraire de la trame vidéo décompressée un premier paramètre de quantification (QP) et acquérir un paramètre QP delta sur la base du premier paramètre QP. Le procédé consiste également à : acquérir un paramètre QP delta sur la base du paramètre QP delta et du premier paramètre QP, compresser la trame vidéo décompressée sur la base du second paramètre QP et transmettre la trame vidéo compressée. Le premier paramètre QP correspond aux options de quantification utilisées à l'origine pour compresser la trame vidéo codée. Le second paramètre QP correspond aux options de quantification pour compresser la trame vidéo décompressée.
