Abstract

The present invention relates to 3D video coding device and method. A decoding method, according to the present invention, provides a 3D video decoding method. A decoding method comprises the steps of: obtaining a disparity value on the basis of a reference view and a predetermined value; deriving movement information of a current block in a depth picture on the basis of the disparity value; and generating a prediction sample of the current block on the basis of the movement information, wherein the reference view is a view of a reference picture in a reference picture list. According to the present invention, even when a base view cannot be accessed, a disparity vector can be derived on the basis of an available reference view index in a decoded picture buffer (DPB), and coding efficiency can be enhanced.

Description

technical field [0001] The present invention relates to technologies related to video coding, and in particular, to a method and device for coding depth pictures in video coding. Background technique [0002] In recent years, demands for high-resolution and high-quality video have increased in various application fields. However, the higher the resolution and quality of video data become, the larger the amount of video data becomes. [0003] Therefore, when the video data is transmitted using a medium such as an existing wired or wireless broadband line, or the video data is stored in an existing storage medium, the transmission cost and its storage cost increase. High-efficiency video compression techniques can be used to efficiently transmit, store and reproduce high-resolution and high-quality video data. [0004] On the other hand, digital broadcasting services using 3D video have attracted attention as next-generation broadcasting services by virtue of the realization...
