Q:

Prove that the equivalent number of bits per pixel for the YUV 4:2:0 scheme is 12

Prove that the equivalent number of bits per pixel for the YUV 4:2:0 scheme is 12

A:

The number of bits to store 4 pixels in YUV 4:2:0 is:
4*8+8+8=48 bits

i.e. 4 bytes for luma and one byte for each color plane
which gives an average of
48/4=12bpp
