| description | The invention relates to a device for double pass encoding of a video data stream comprising: - a first type encoding means (5, 6) performing the first encoding pass, - a second type encoding means (2, 4) performing the second encoding pass. According to the invention, - the second type encoding means (2, 4) are different from the first type encoding means (5, 6) and - the second type encoding means (2, 4) use encoding information originating from the first encoding pass.
L'invention se rapporte à un dispositif de codage en passage double d'un flot de données vidéo comprenant : des premiers moyens de codage de type (5, 6) effectuant le premier passage de codage, des seconds moyens de codage de type (2, 4) effectuant le second passage de codage. Selon l'invention, les seconds moyens de codage de type (2, 4) sont différents des premiers moyens de codage de type (5, 6) et les seconds moyens de codage de type (2, 4) utilisent une information de codage provenant du premier passage de codage. L'invention trouve une application dans le codage MPEG-2 et H.264. |
