High Efficiency Video Coding(HEVC)... is a draft video compression standard, a successor to H. 264/MPEG-4 AVC(Advanced Video Coding), currently under joint development by the ISO/IEC [International Electrotechnical Commission] Moving Picture Experts Group(MPEG) and ITU [International Telecommunication Union]-T Video Coding Experts Group(VCEG). MPEG and VCEG have established a Joint Collaborative Team on Video Coding(JCT-VC) to develop the HEVC standard. HEVC improves video quality and doubles the data compression ratio compared to H. 264, and scales from 320 240 to 7680 4320 pixels resolution. 1, record 1, English, - high%20efficiency%20video%20coding

Le domaine de l'invention est celui du codage et du décodage d'images ou de séquences d'images, et notamment de flux vidéo. Plus précisément, l'invention concerne la compression d'images ou de séquences d'images utilisant une représentation par blocs des images. L'invention peut notamment s'appliquer au codage vidéo mis en œuvre dans les codeurs vidéo actuels (MPEG, H.264, etc. et leurs amendements) ou à venir (ITU-T/ISO HEVC, en anglais «High-Efficiency Video Coding» pour codage vidéo à haute efficacité), et au décodage correspondant. 4, record 1, French, - codage%20vid%C3%A9o%20%C3%A0%20haute%20efficacit%C3%A9

According to HEVC [high efficiency video coding] WD [working draft] 7, a coded video sequence and an access unit are defined as follows : Coded video sequence : A sequence of access units that consists, in decoding order, of a CRA [clean random access] access unit that is the first access unit in the bitstream, an IDR [instantaneous decoder refresh] access unit or a BLA [broken link access] access unit, followed by zero or more non-IDR and non-BLA access units including all subsequent access units up to[, ] but not including any subsequent IDR or BLA access unit... 1, record 2, English, - coded%20video%20sequence

Dans une séquence d'images vidéo, le volume de calcul à effectuer pour le décodage de la trame entrante n'est pas connu à l'avance, il faut donc un modèle d'estimation. Des mesures éffectuées sur les différents types de trames d'une séquence vidéo codée en H.264 montre que les durées de calcul sont groupées en plages de valeurs bruitées assez uniformes, séparées par des pics isolés dont l'amplitude peut aller jusqu'à trois fois la valeur moyenne. 1, record 2, French, - s%C3%A9quence%20vid%C3%A9o%20cod%C3%A9e
