Apparatus and method for parallel encoding and decoding image data based on correlation of macroblocks

摘要

An apparatus and method provide parallel encoding and decoding of image data based on correlation of macroblocks. To encode and decode image data having a high resolution, an encoding order may be determined based on a correlation between blocks of the image data, and a decoding order may be determined based on the determined encoding order, thereby efficiently processing the blocks in parallel.

主权项

1. An image data processing apparatus, comprising:
an encoding processing unit comprising: a parallel candidate block extractor to determine at least one candidate block set comprising at least one candidate block among a plurality of blocks of image data, each candidate block included in the at least one candidate block set being expected to have no correlation with other candidate blocks included in the at least one candidate block set, a block encoder to encode the determined at least one candidate block set, and a parallel and encoding order determiner to adaptively determine an encoding order of the at least one candidate block in the at least one candidate block set based on a correlation of encoded at least one candidate block.
