    • Scaling of video is performed using area weighted averaging of input pixels to calculate coefficients to multiply with luminescence and crominence of input pixels. Such coefficients are produced for both the vertical and horizontal scaling directions of the input video stream. When scaling down or scaling up, scaling is first performed in the vertical direction to produce partially scaled pixels, which are then utilized for scaling in the horizontal direction. When scaling up, a pre-interpolation or pre-replication process is utilized to double the inputted pixel grid which doubled pixel grid is then utilized to scale down to the desired pixel grid size, which is greater than the originally inputted pixel grid size.
    • 使用输入像素的区域加权平均来执行视频的缩放,以计算与输入像素的发光和色度相乘的系数。 对于输入视频流的垂直和水平缩放方向都产生这样的系数。 当缩小或缩小时,首先在垂直方向上执行缩放以产生部分缩放的像素,然后将其用于水平方向上的缩放。 当放大时,使用预插入或预复制过程将输入的像素网格加倍,然后将双倍像素网格用于缩小到大于原始输入的像素网格尺寸的期望像素网格大小。
