Embodiment Construction

[0068] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0069] Encoding and decoding of video is performed in units of blocks. For example, encoding / decoding processes such as transform, quantization, prediction, in-loop filtering, or reconstruction may be performed on an encoding block, transform block, or prediction block.

[0070] Hereinafter, the block to be encoded / decoded is referred to as a "current block". For example, depending on the current encoding / decoding process step, the current block may represent an encoding block, a transform block or a prediction block.

[0071] In addition, the term "unit" used in this specification means a basic unit for performing a specific encoding / decoding process, and a "block" can be understood to mean an array of samples of a predetermined size. Unless stated otherwise, "block" and "unit" are used interchangeably. For example, in an embodiment to be desc...

Abstract

The video decoding method according to the present invention includes the steps of: generating a merging candidate list for the first block; selecting any one of the merging candidates included in the merging candidate list; and The first block performs motion compensation. At this time, based on the number of spatial merging candidates and temporal merging candidates included in the merging candidate list, the inter merging candidates included in the inter motion information list may be added to the merging candidate list.
