Abstract

Innovations in intra block copy (“BC”) prediction as well as innovations in encoder-side search patterns and approaches to partitioning. For example, some of the innovations relate to use of asymmetric partitions for intra BC prediction. Other innovations relate to search patterns or approaches that an encoder uses during block vector estimation (for intra BC prediction) or motion estimation. Still other innovations relate to uses of BV search ranges that have a horizontal or vertical bias during BV estimation.
