Dear Sir/Madam,

 

We are using ADV7441A and have a question.

Our usage:input is NTSC and output is Y/Cb/Cr.

 

The default value of the blue output is (Y, Cb, Cr=52,192,112).

pls refer to the chart. below,

 

Would you teach us the equation of Y, Cb,and Cr?.

ex. ITU-R BT.601 Y = 0.299R + 0.587G + 0.114B

   Cr = -0.16874R - 0.33126G + 0.5B

   Cb = 0.5R - 0.41869G - 0.081B

 

It would be greatly appreciated if advice could be gotten.

 

Sincerely yours,

Kou
