A The YUV 4:2:0 sampling mode is half the size of the YUV 4:4:4 sampling mode.

B For human eyes, the Y component in YUV is the most important. Therefore, downsampling can be performed on the UV components.

C RGB components have weak correlation, which is unfavorable for video image compression. Therefore, RGB is often used for image display.

D The transmission rate of video data using YUV 4:2:0 is 140 Mbit/s. If the 4:2:2 mode is used, the transmission rate required by the video is 175 Mbit/s.
