    Abstract: A method for parallel processing of a video frame in accordance with principles of inventive concepts may include dividing the video frame into N tiles in a direction perpendicular to a raster scan direction; and sequentially encoding or decoding coding tree blocks included in each of the N tiles from a first row to an mth row according to the raster scan direction, wherein encoding or decoding of an Kth tile (K being a natural number more than 2 and less than N) starts at a point of time when encoding or decoding of coding tree blocks included in a first row of a (K−1)th tile is completed.

    Abstract translation: 根据本发明概念的原理并行处理视频帧的方法可以包括:将视频帧划分成垂直于光栅扫描方向的方向的N个瓦片; 并且根据光栅扫描方向从第一行到第m行顺序编码或解码包括在N个瓦片中的每个N个瓦片中的编码树块,其中编码或解码第K个瓦片(K是大于2并小于 N)在(K-1)瓦片的第一行中包括的编码树块的编码或解码的时间点开始。

    Abstract: A method, executed by an encoding circuit, for selecting an optimal decimated grid includes estimating, among a plurality of decimated grids within a coded block, a weight decimation error for each of a vertical decimated grid and a horizontal decimated grid. A weight decimation error is estimated for each of remaining decimated grids among the plurality of decimated grids based on a corresponding weight decimation error among the vertical decimated grid and the horizontal decimated grid. For each of the plurality of decimated grids, an initial combined error is determined by combining the weight decimation error and a color format choice error. Two decimated grids having the least initial combined errors, among the plurality of decimated grids, are selected as optimal decimated grids.
