What is the difference between 2160p RGB and YUV420?
The main difference between 2160p RGB and YUV420 lies in the way they process and display color information. 2160p RGB uses the additive color model, where red, green, and blue (RGB) values are combined to create the final image. On the other hand, YUV420 uses a color difference model, where the luminance (brightness) and chrominance (color) components are separated and processed differently.
In general, 2160p RGB is considered to be a more accurate and detailed color representation, as it maintains the full range of RGB values. However, YUV420 is more commonly used in video compression and broadcasting due to its ability to reduce bandwidth and storage requirements. This is achieved by subsampling the chrominance components, which can lead to a loss of color detail.
