Hi,
4:2:0  is the YUV Sub sampled format
For every 4 Luminance component there will be there will be 1 chrominance 
component each ( ie 1 U and 1 V)
this concept is called sub sampling of chroma component with respect to 
luma component.
The are other formats of YUV is
4 : 1 : 1 ----------- 1 U & 1V  for every 4 Y component ( the direction 
sub sampling is defer with 4:2:0 )
4: 0: 0   ----------  No chroma component
4: 2 : 2  ----------  2 U & 2V for every 4 Y component
Regards,
Dakshin.

Hi, 
      I have come across terms like YCbCr  4:2:0 format 
I found that YCbCr is YUV. Can anyone explain 4:2:0 and other such formats 
if any?
Regards 
Nilesh
