阅读说明：本技术 视频编解码设备、方法和计算机可读记录介质 (Video encoding and decoding apparatus, method and computer-readable recording medium ) 是由 韩钟基 李在荣 于 2016-01-11 设计创作，主要内容包括：公开了视频编解码设备、方法和计算机可读记录介质。视频编码设备包括：比特流生成单元、运动预测单元、运动矢量编码单元、差分信号生成单元。差分信号是通过从目标块减去预测块来生成的,其中,运动矢量编码单元被配置为,当要编码的目标块的运动矢量的分辨率是整像素分辨率时,利用要编码的目标块的运动矢量的分辨率,根据要映射的相邻块的运动矢量的子像素单元中的值,将相邻块的运动矢量映射到对应于整像素单元中的值的值,以及其中,运动矢量编码单元通过从相邻块的运动矢量的子像素单元中的值消除可用于以子像素单元表示但是不可用于以整像素单元表示的值,来执行相邻块的运动矢量的映射。(Disclosed are a video encoding and decoding apparatus, a method and a computer-readable recording medium. The video encoding device includes: a bit stream generation unit, a motion prediction unit, a motion vector coding unit, and a differential signal generation unit. The differential signal is generated by subtracting the prediction block from the target block, wherein the motion vector encoding unit is configured to map the motion vectors of the adjacent blocks to values corresponding to values in integer-pixel units according to values in sub-pixel units of the motion vectors of the adjacent blocks to be mapped, using the resolution of the motion vector of the target block to be encoded, when the resolution of the motion vector of the target block to be encoded is integer-pixel resolution, and wherein the motion vector encoding unit performs mapping of the motion vectors of the adjacent blocks by eliminating values available for representation in sub-pixel units but unavailable for representation in integer-pixel units from values in sub-pixel units of the motion vectors of the adjacent blocks.)
