Abstract: Abstract A method of decoding video performed by a decoding device, the method comprising: deriving an intra prediction mode of a current block from prediction mode information; deriving neighboring samples including upper neighboring samples of the current block; and generating prediction samples of the current block based on the intra prediction mode and the neighboring samples of the current block, wherein the upper neighboring samples include upper neighboring samples of an n-th row located in an upward direction away from an uppermost row of the current block, wherein n is positive integer more than 1, wherein a number of the upper neighboring samples of the n-th row is more than 2N based on a size of the current block being NxN, wherein N is a positive integer, wherein sample values of additional upper neighboring samples located to right of a 2N-th upper neighboring sample among the upper neighboring samples of the n-th row are derived to be equal to a sample value of the 2N-th upper neighboring sample without determining whether the additional upper neighboring samples are positioned at unavailable sample positions, and wherein coordinates of the 2N-th upper neighboring sample is (2N-1, -n) based on coordinates of the top-left sample in the current block being (0, 0).

Abstract: Se proporciona un método y un aparato de codificación/decodificación de vídeo para realizar PDPC, así como un método para transmitir un flujo de bits. Un método de decodificación de vídeo, realizado por un aparato de decodificación de vídeo según la presente divulgación, puede comprender los siguientes pasos: generar un bloque de predicción mediante la intrapredicción de un bloque actual; determinar si se aplica PDPC al bloque de predicción; y, con base en esta determinación, generar un bloque de predicción final del bloque actual mediante la aplicación de PDPC al bloque de predicción. El paso para determinar si se aplica PDPC al bloque de predicción puede incluir: determinar si el tamaño del bloque actual cumple una condición predeterminada; determinar si se aplica PDPC al bloque de predicción en función de si el tamaño del bloque actual cumple la condición predeterminada; y, si el tamaño del bloque actual no cumple la condición predeterminada, omitir la determinación de un componente de color del bloque actual y determinar que no se aplica PDPC al bloque de predicción.
