ABSTRACT:
In a method of encoding/decoding a video sequence, which is composed of video frames, 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.
