Abstract: A method for creating a personal area network identifier (PAN ID) of a network in a wireless communication system includes creating a first PAN ID; receiving a message including a second PAN ID from a source coordinator; comparing the first PAN ID with the second PAN ID included in the received message; and when the first PAN ID and the second PAN ID are the same according to the comparison result, transmitting an indication message related to a PAN ID conflict to the source coordinator, wherein at least any one of the first PAN ID and the second PAN ID may be created through a hash algorithm and the indication message may include at least any one of a conflicted PAN ID or an error code indicating a conflict.

Abstract: An image decoding method performed by means of a decoding device according to the present disclosure comprises the steps of: configuring an affine merge candidate list with respect to a current block; deriving CPMVs with respect to CPs of the current block on the basis of the affine merge candidate list; deriving prediction samples with respect to the current block on the basis of the CPMVs; and generating a reconstructed picture with respect to the current block on the basis of the derived prediction samples, wherein the maximum number of inherited affine candidates is two, a first inherited affine candidate is derived on the basis of a left block group of the current block, and a second inherited affine candidate is derived on the basis of an upper block group of the current block.

Abstract: An image decoding method performed by a decoding apparatus includes the operations: deriving a correspondence block corresponding to the current block of the current picture, the correspondence block being located in a co-located picture; deriving a movement vector of the correspondence block; scaling the movement vector of the correspondence block based on a first temporal distance and second temporal distance, the first temporal distance being the difference between the POC values of the co-located picture and POC values of the reference picture of the correspondence block, and the second temporal distance being the difference between the POC values of the co-located picture and POC values of the current picture containing the current block; deriving the movement vector updated based on the scaled movement vector and location of the current block; and deriving a movement vector of the current block based on the updated movement vector.

Abstract: Disclosed are a method for decoding a video signal and an apparatus therefor. Specifically, a method for decoding an image based on an inter-prediction mode may include: configuring a merge candidate list by using motion information of a spatial candidate and a temporal candidate adjacent to a current block; parsing a first syntax element indicating a particular candidate applied to inter-prediction of the current block among a predefined number of candidates in the merge candidate list; deriving a refined candidate by adding a motion vector offset to a motion vector of a candidate indicated by the first syntax element; and generating a prediction block of the current block by using the motion information of the refined candidate.

Abstract: Disclosed are a method for processing a video signal by using an affine motion prediction and an apparatus thereof. A method for processing a video signal according to the present disclosure may include: adding, to an affine candidate list, an affine coded block coded in an affine prediction mode among neighbor blocks of a current block; obtaining a syntax element indicating a candidate used for the affine motion prediction of the current block in the affine candidate list; deriving a control point motion vector predictor of the current block based on an affine motion model of the candidate indicated by the syntax element; deriving a control point motion vector of the current block by adding a control point motion vector difference to the control point motion vector predictor; and generating a prediction block of the current block by using the control point motion vector of the current block.
