1. A decoder for reconstructing a sample array of a video from a data stream, the decoder configured to:
determine a set of wedgelet patterns to decode a block of the sample array of the video, wherein each wedgelet pattern of the set corresponds to a line defined by a start position and an end position, the line dividing the corresponding wedgelet pattern into two wedgelet portions;
extract, from the data stream, information related to a selected wedgelet pattern of the set of wedgelet patterns;
obtain the selected wedgelet pattern from the set of wedgelet patterns based on the information; and
decode the block based on the two wedgelet portions yielded by the line corresponding to the selected wedgelet pattern.
