Abstract

La présente invention concerne un procédé d'évaluation de qualité vidéo, un dispositif et une tête radio distante. Un dispositif d'évaluation de qualité vidéo reçoit un flux vidéo d'une vidéo à évaluer, le flux vidéo comprenant une pluralité de trames vidéo, chaque trame vidéo de la pluralité de trames vidéo étant portée dans au moins un paquet vidéo ; le dispositif d'évaluation de qualité vidéo reçoit des informations d'indication provenant d'une tête radio distante, les informations d'indication étant utilisées pour indiquer une relation de correspondance entre le type de trame de chacune de la pluralité de trames vidéo et le paquet vidéo correspondant à la trame vidéo ; et le dispositif d'évaluation de qualité vidéo détermine un résultat d'évaluation de qualité vidéo de la vidéo à évaluer, selon le flux vidéo de la vidéo à évaluer et ses informations d'indication. La présente invention peut être utilisée pour évaluer avec précision la qualité d'une vidéo.
