    Abstract: 디코딩하기위한방법들및 디바이스들은, 어느픽처가병치된픽처인지를결정하고, 그리고병치된픽처에서의연관된블록과현재코딩픽처에서의현재블록사이의초기모션벡터를찾기위해현재코딩픽처에서의이전에디코딩된블록들을사용하는것에기초하여, 현재코딩픽처에서의비디오데이터의현재블록에대응하는병치된픽처에서의비디오데이터의연관된블록의위치를결정하도록구성된프로세서를포함하고, 여기서, 비디오데이터의연관된블록은적어도하나의제 1 도출된모션벡터를포함한다. 프로세서는, 병치된픽처에서의연관된블록과연관되는적어도하나의제 1 도출된모션벡터에기초하여, 초기모션벡터가병치된픽처를포인팅할경우, 현재코딩픽처에서의현재블록과연관되는적어도하나의제 2 도출된모션벡터를결정하도록구성된다.

    Abstract: Los sistemas y técnicas para procesar datos de vídeo incluyen una tabla de predictores de vectores de movimiento (HMVP) basada en historial con dos o más candidatos HMVP. La primera entrada de la tabla, asociada a un primer valor de índice, incluye un primer candidato HMVP, y la segunda, asociada a un segundo valor de índice, incluye un segundo candidato HMVP, siendo el primer valor de índice inferior al segundo. Para una lista de candidatos de predicción avanzada de vectores de movimiento (AMVP), se seleccionan uno o más candidatos HMVP de la tabla en orden inverso, donde el segundo candidato HMVP se selecciona antes que el primero, según el orden inverso. Los candidatos HMVP seleccionados se añaden a la lista de candidatos AMVP. Esta lista puede utilizarse para ejecutar AMVP para uno o más bloques de datos de vídeo.

    Abstract: Systems and techniques for processing video data include a history-based motion vector predictor (HMVP) table with two or more HMVP candidates, where a first entry of the HMVP table associated with a first index value includes a first HMVP candidate and a second entry of the HMVP table associated with a second index value includes a second HMVP candidate, the first index value being lower than the second index value. For an advanced motion vector prediction (AMVP) candidate list, one or more HMVP candidates from the HMVP table are selected in a reverse order, where the second HMVP candidate is selected before the first HMVP candidate according to the reverse order. The selected one or more HMVP candidates are added to the AMVP candidate list. The AMVP candidate list can be used to perform AMVP for the one or more blocks of video data.

    Abstract: In one example, a method of coding video data includes responsive to determining to predict a current block of a current picture of video data using intra block copy (IBC), generating a motion vector (MV) candidate list for the current block, wherein generating the MV candidate list comprises: determining one or more history-based motion vector prediction (HMVP) candidates; and including, as a last candidate in the MV candidate list, an HMVP candidate of the one or more HMVP candidates; selecting, from the MV candidate list, a particular MV candidate that identifies a predictor block in the current picture; and reconstructing pixels of the current block based on pixels of the predictor block.

El uno o más candidatos HMVP seleccionados se agregan a la lista de candidatos AMVP. La lista de candidatos AMVP se puede utilizar para llevar a cabo el AMVP para el uno o más bloques de datos de video.
