1. Apparatus for picture decoding, configured to
select, out of a search area of a picture, a set of one or more patches which match a template area adjacent to a predetermined picture block; and
predictively decode the predetermined picture block from a data stream based on the set of one or more patches,
wherein the apparatus is configured to select the search area out of a plurality of subareas into which an overall search area associated with the predetermined picture block is sub-divided, based on a signalization in the data stream,
wherein the template area and the predetermined picture block are within a further picture and the overall search area is displaced from a position within the picture collocated to the predetermined picture block by a vector, wherein the apparatus is configured to derive the vector from the data stream.
