Abstract
A video signal decoding device is disclosed. The video signal decoding device comprises a processor, and the processor obtains motion information from neighboring blocks of a current block and corrects the motion information to obtain motion information of the current block.
Claims13
A video signal decoding apparatus comprising a processor,
- wherein the processor is configured to:
- when a current block is a boundary block adjacent to a picture boundary of a current picture comprising the current block, acquire a padding reference block from a first reference picture for the current picture based on the first reference picture and motion information of the boundary block, generate a padding area adjacent to the boundary block based on the padding reference block, and generate a second reference picture for a next picture using the padding area.
A video signal encoding apparatus comprising a processor,
- wherein the processor is configured to acquire a bitstream that is decoded by a decoding method, and
- wherein the decoding method comprises:
- when a current block is a boundary block adjacent to a picture boundary of a current picture comprising the current block, acquiring a padding reference block from a first reference picture for the current picture based on the first reference picture and motion information of the boundary block, generating a padding area adjacent to the boundary block based on the padding reference block, and generating a second reference picture for a next picture using the padding area.
A computer-readable non-transitory storage medium for storing a bitstream,
- wherein the bitstream is decoded by a decoding method, and
- wherein the decoding method comprises:
- when a current block is a boundary block adjacent to a picture boundary of a current picture comprising the current block, acquiring a padding reference block from a first reference picture for the current picture based on the first reference picture and motion information of the boundary block, generating a padding area adjacent to the boundary block based on the padding reference block, and generating a second reference picture for a next picture using the padding area.
