Document Type and Number:
WIPO Patent Application WO/2018/128248
Kind Code:
A1
Abstract:
An image decoding method executed by a decoding device, according to the present invention, comprises the steps of: receiving 360-degree video information; deriving processing units of a projected picture; on the basis of the 360-degree video information, deriving an IU flag for a target processing unit among the processing units; and if the IU flag for the target processing unit indicates that the target processing unit is invalid, deriving a sample value of a sample of the target processing unit by a predetermined specific value, wherein the IU flag for the target processing unit indicates whether or not the target processing unit is an invalid region.
