Document Type and Number:
WIPO Patent Application WO/2021/049586
Kind Code:
A1
Abstract:
An encoding device (100) comprises a circuit and a memory connected to the circuit, wherein the circuit in operation encodes sub-picture information. The sub-picture information represents a sub-picture region, which is commonly defined in a plurality of pictures constituting a moving image, using a plurality of Coding Tree Units (CTUs) defined commonly and in a grid in the plurality of pictures. The sub-picture information includes information which represents, using the plurality of CTUs, a horizontal position and a vertical position of the sub-picture region commonly defined in the plurality of pictures.
