YCbCr 4:2:0

Started by Dok April 1, 2004
Hi!

How does the 4:2:0 Chrominance format look like in
data stream?

Say I have these pixels...

Y0 Y1 Y4 Y5 ...
Cb0/Cr0 Cb1/Cr1 ...
Y2 Y3 Y6 Y7 ...
.
.
.

Is it like,

Y0,Y1,Y2,Y3,Cb0,Cr0,Y4,Y5,Y6,Y7,Cb1,Cr1....

or something else?

Thanks,
Dok __________________________________



most of the time, all the Y components are written first later Cb and then
Cr.
i.e. Y0 Y1 Y4 Y5...Cb0,Cb1,...Cr0,Cr1,...
Note that all the components are written row wise...
