Abstract

The present invention provides a method for decoding a video signal, comprising the steps of: acquiring a split flag from the video signal, wherein the split flag indicates whether a coding unit is split; acquiring split type information of the coding unit from the video signal if the coding unit is split according to the split flag, wherein the split type information includes embedded block type information and the embedded block type information indicates that a split block (EBP) is a block located at an arbitrary spatial location in the coding unit; and decoding the coding unit on the basis of the split type information of the coding unit.

Description

technical field [0001] The present invention relates to a method and apparatus for encoding and decoding video signals based on embedded block partitioning, and more particularly, to a quadtree (QT) decomposition using embedded block partitioning. Background technique [0002] Compression coding refers to a series of signal processing techniques for sending digitized information over communication lines or storing digitized information in a form suitable for a storage medium. Media such as video, images and speech can be the subject of compression encoding. Specifically, a technique for performing compression encoding on video is called video compression. [0003] Next-generation video content is expected to be characterized by high spatial resolution, high frame rate, and high-dimensional video scenes. Processing of such content would require significantly increased storage, memory access rates, and processing power. [0004] Therefore, it is desirable to design a coding...
