    Abstract: Provided is an interlayer video decoding method according to an embodiment including obtaining prediction-mode information of a current block of a depth image from a bitstream, generating a prediction block of the current block on the basis of the prediction-mode information, and decoding the depth image by using the prediction block. The obtaining of the prediction-mode information of the current block from the bitstream includes receiving a first flag, a second flag, and a third flag, wherein the first flag indicates whether prediction of the current block by dividing the current block into two or more partitions according to a pattern is permitted, the second flag indicates whether the depth image permits blocks of the depth image to be predicted by dividing the blocks into two or more partitions by using a wedgelet, and the third flag indicates whether the depth image permits the blocks of the depth image to be predicted by dividing the blocks into two or more partitions by using a contour; and receiving a fourth flag from the bitstream when predetermined conditions determined on the basis of the first to third flags are satisfied, wherein the fourth flag represents information regarding a type of a method of dividing the current block into two or more partitions according to the pattern.

    Abstract: Disclosed is a depth map frame decoding method including reconstructing a color frame obtained from a bitstream based on encoding information of the color frame; splitting a largest coding unit of a depth map frame obtained from the bitstream into one or more coding units based on split information of the depth map frame; splitting the one or more coding units into one or more prediction units for prediction decoding; determining whether to split a current prediction unit into at least one partition and decode the current prediction unit by obtaining information indicating whether to split the current prediction unit into the at least one or more partitions from the bitstream; if it is determined that the current prediction unit is to be decoded by being split into the at least one or more partitions, obtaining prediction information of the one or more prediction units from the bitstream and determining whether to decode the current prediction unit by using differential information indicating a difference between a depth value of the at least one or more partitions corresponding to an original depth map frame and a depth value of the at least one or more partitions predicted from neighboring blocks of the current prediction unit; and decoding the current prediction unit by using the differential information based on whether to split the current prediction unit into the at least one or more partitions and whether to use the differential information.

    Abstract translation: 本发明公开了一种深度图帧解码方法，包括：根据所述彩色帧的编码信息重构从位流获得的彩色帧; 基于深度图帧的分割信息，将从比特流获得的深度图帧的最大编码单位分割成一个或多个编码单位; 将所述一个或多个编码单元分割成一个或多个预测单元进行预测解码; 确定是否将当前预测单元拆分成至少一个分区，并且通过获取指示是否将当前预测单元分解成来自比特流的至少一个或多个分区的信息来解码当前预测单元; 如果确定当前预测单元要被分解为至少一个或多个分区进行解码，则从比特流获得一个或多个预测单元的预测信息，并通过使用差分来确定是否解码当前预测单元 指示与原始深度图帧对应的至少一个或多个分区的深度值与从当前预测单元的相邻块预测的至少一个或多个分区的深度值之间的差异的信息; 以及通过使用基于是否将当前预测单元分割成至少一个或多个分区的差分信息以及是否使用差分信息来解码当前预测单元。
