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 article, a method of encoding the residual block includes generating a prediction block of a current block, generating a residual block based on a difference between the prediction block and the current block; and splitting the transformation residual block into frequency band units, in which nonzero effective transformation coefficients exist.

TL;DR: In this paper, a method and apparatus of encoding a video, including encoding the video data of maximum coding unit based on deeper coding units of hierarchical structures according to at least one split region of the maximum coding units, with performing inter prediction using partitions obtained by splitting the coding unit according to arbitrary ratios, and determining a coding depth.

TL;DR: A concept of a quadtree based nonsquare block coding structure is presented in this paper for the emerging High Efficiency Video Coding standard, which includes a quadrupletree based asymmetric motion partitioning scheme and a nonsquared quadtree transform (NSQT) algorithm.

TL;DR: In this paper, a video decoding method and apparatus based on a scanning order of hierarchical data units are provided, where the decoding method includes: receiving and parsing a bitstream of an encoded video; extracting from the bitstream information about a size of a maximum coding unit for decoding a picture of the encoded video, and encoding information about the coded depth and an encoding mode for coding units of the picture.
