separate Y from CbCr in dsp builder

Hi

I am using dsp builder v6.0 and cyclone II and tvp5146 daughter-card.

I have YCbCr video data in two color spaces 4:2:2 in sequence(on the same 8bit data bus). I want to separate Y component from CbCr in YCbCr using dsp builder.

can you help me please!

thank You
