    • The present invention relates to inter-view residual prediction and is characterized by obtaining residual data of a first reference block by using a motion vector of a neighboring block, obtaining residual data of a second reference block by using a reference view motion vector or a disparity vector, obtaining a residual data prediction value by using the residual data of the first reference block and the residual data of the second reference block, and coding a current texture block by using the residual data prediction value. The present invention can perform inter-view residual prediction by using a prediction value obtained using coded data of another view point belonging to the same time band to increase the accuracy of video data prediction by using a correlation between view points and reduce the amount of residual data to be transmitted, thereby improving the coding efficiency. In addition, the complexity in a coding process may be reduced by adding a condition for applying the inter-view residual prediction.
    • 本发明涉及视图间残差预测,并且其特征在于通过使用相邻块的运动矢量获得第一参考块的残差数据,通过使用参考视角运动矢量或视差获得第二参考块的残差数据 向量,通过使用第一参考块的残差数据和第二参考块的残差数据来获得残差数据预测值,并且通过使用残差数据预测值对当前纹理块进行编码。 本发明能够通过使用使用属于相同时间带的另一个视点的编码数据获得的预测值来执行视图间残差预测,以通过使用视点之间的相关性来增加视频数据预测的准确性并且减少残差量 数据被传送,从而提高编码效率。 另外,通过添加用于应用视图间残差预测的条件,可以减少编码处理中的复杂度。
