TL;DR: Technical details of the block partitioning structure of HEVC are introduced with an emphasis on the method of designing a consistent framework by combining the three different units together and experimental results are provided to justify the role of each component.

Abstract: Disclosed are a method and a apparatus for encoding a video, and a method and apparatus for decoding a video, in which neighboring pixels used to perform intra prediction on a current block to be encoded are filtered and intra prediction is performed by using the filtered neighboring pixels.

TL;DR: A novel video compression scheme based on a highly flexible hierarchy of unit representation which includes three block concepts: coding unit (CU), prediction unit (PU), and transform unit (TU), which was a candidate in the competitive phase of the high-efficiency video coding (HEVC) standardization work.

TL;DR: In this paper, a method and apparatus for encoding a video by using block merging and a method for decoding a video with block merging is presented. But the method of encoding includes: determining an encoding mode indicating a current data unit for encoding of a picture and an encoding method including prediction encoding performed for the current data units; determining an occurrence of merging with at least one neighboring data unit based on at least the encoding mode and a prediction mode; and determining prediction mode information, merging related information, and prediction related information.

TL;DR: In this paper, a method and apparatus for decoding a video and a method for encoding a video are provided, which includes: receiving and parsing a bitstream of an encoded video, extracting, from the bitstream, encoded image data of a current picture of the encoded video assigned to a maximum coding unit, and information about a coded depth and an encoding mode according to the maximum coding units.
