    摘要: Embodiments of the present invention disclose a picture encoding method and a terminal. The terminal includes: dividing, by a terminal based on reference information of each of a plurality of pictures, the plurality of pictures into N groups, where the reference information of each picture of a same group satisfies a preset similarity condition, and the reference information includes information that is used to describe a characteristic of the picture and that is generated when the picture is taken; and encoding, by the terminal, the N groups of pictures, where the following steps are performed on any one of the N groups of pictures: selecting a first picture from a target group based on a preset rule, and encoding the first picture, where the first picture is a picture first encoded in the target group, and the target group is any one of the N groups of pictures; selecting a reference picture for a second picture from the target group, where the second picture is a picture in the target group other than the first picture; and performing motion estimation on the second picture by using the reference picture, to encode the second picture. Use of the embodiments of the present invention can make a data volume of obtained encoded information smaller.

    摘要: The present invention relates to a system and a method for encoding a video stream. The encoding includes determining a level of relevance for areas in an image frame to be included in the video stream, determining a block size value for coding blocks in the image frame, the block size value is depending on the level of relevance determined for the area including each coding block, respectively, encoding the image frame using coding block sizes based on the determined block size values for each of the coding blocks.

    摘要: L'invention concerne un procédé de traitement d'un flux vidéo avant encodage, le flux vidéo étant susceptible de comporter un grain de film, le procédé comportant :
    - une mesure d'une intensité de grain de film dans le flux vidéo ;
    - une obtention d'au moins une information de débit d'encodage associé au flux vidéo, pour déterminer un couple de valeurs respectives d'intensité de grain et de débit d'encodage ;
    - une comparaison des valeurs du couple avec des valeurs seuils respectives prédéterminées pour catégoriser le flux vidéo par rapport à des couples de valeurs prédéterminées d'intensité de grain et de débit ; et
    - un choix d'une stratégie de gestion de grain de film parmi au moins quatre combinaisons résultant de la catégorisation du flux vidéo.
