Abstract

The present invention provides a 3D video decoding method and device. A 3D video decoding method according to the present invention comprises the steps of: determining whether to apply motion vector inheritance for inducing a motion vector of a depth picture, using motion information of a texture picture; when it is determined to apply the motion vector inheritance, inducing a current block within the depth picture to a sub-block sized depth sub-block for the motion vector inheritance; inducing a motion vector of the depth sub-block from a texture block within the texture picture corresponding to the depth sub-block; and inducing a reconstructed sample of the current block by generating a prediction sample of the depth sub-block on the basis of the motion vector of the depth sub-block.

Description

technical field [0001] The present invention relates to techniques associated with video coding, and more particularly, to the coding of 3D video pictures. Background technique [0002] In recent years, the demand for high-resolution and high-quality video has grown 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 video data is transmitted using such as an existing wired or wireless broadband line or is stored in an existing storage medium, the transmission cost and its storage cost increase. High-efficiency video compression technology 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 with the realization of the ability to process high-resolution / large-capacity vide...
