FIELD: electrical communication engineering.
SUBSTANCE: group of inventions relates to encoding and decoding data. For this purpose, a data encoding method implemented in a computing device that implements a video encoder or image encoder is used, computing device configured to encode data and a computer-readable media storing computer-executable instructions for causing a computing device programmed thereby to perform operations are also used. Some of the innovations relate to estimation of reconstructed sample values within an overlap area of a current block during block vector ("BV") estimation. Other innovations relate to prediction of block vector ("BV") values during encoding or decoding using "ping-pong" approaches, in which an encoder or decoder selects between a pair of candidate BV values when predicting the BV value for a block.
EFFECT: technical result is wider range of means.
