A method of video compression may include providing and transmitting encoder commands from a sequence of one or more pixels in a video frame in a YCbCr color space of a set of hierarchical encoder commands. The particular encoder command for the particular sequence may include one of a copy command, a delta command, or a generation pixel command. The copy command may indicate that the particular sequence is the same as one of a previous pixel in the video frame, a pixel located above a first pixel of the particular sequence in the video frame, or a pixel in the previous video frame at the location of the first pixel. The delta command may indicate that the particular sequence includes a single pixel having a color value equal to a previous pixel in the video frame in conjunction with a signed color delta. Generating the pixel command may provide a particular sequence of color values. 一种视频压缩方法可以包括提供和传输来自一组分层编码器命令的YCbCr色彩空间中的视频帧中的一个或更多个像素的序列的编码器命令。用于特定序列的特定编码器命令可以包括复制命令、增量命令或生成像素命令中的一个。复制命令可以指示特定序列与视频帧中的先前像素、位于
