A method of encoding/decoding a video sequence, which is composed of video frames. In the method, at least one video frame is divided into a set of coding blocks, and at least one of the coding blocks is encoded by intra- coding. Then a first reliable region that comprises at least one intra-coded coding block is determined, and the first reliable region in the video sequence is encoded such that creation of an information dependency between the first reliable region and coding blocks outside the first reliable region is prevented.
La présente invention a trait à un procédé de codage/décodage d'une séquence vidéo, constituée d'images vidéo. Dans ce procédé, on divise au moins une image vidéo en un ensemble de blocs de codage, et on soumet au moins un des blocs de codage à un intra-codage. Ensuite on détermine une première zone fiable comportant au moins un des blocs soumis à intra-codage, et on effectue le codage de la première zone fiable dans la séquence vidéo de manière à empêcher la création d'une information de dépendance entre la première zone viable et les blocs de codage hors de la première zone fiable.
