15. An encoder for encoding a video into a data stream, comprising: an entropy encoder configured to encode syntax elements related to the video into the data stream based on one or more of a plurality of contexts used in binary entropy encoding, wherein the entropy encoder is configured to initialize each of the plurality of contexts based on, for each context, a slope value and an offset value, wherein the slope value and the offset value are determined based on first and second four-bit parts of an 8-bit initialization value associated with the context.
26. The encoder according to claim 15 , wherein the data stream comprises at least a portion associated with depth values related to a depth map.
