FIR 2D behavioural

> I get an elaboration ONLY on the luma plane?

I may have misunderstood your question but I think the answer is no. If you attempt to send YCbCr 4:2:2 into the 2DFIR you will have to parameterize the input as two channels in sequence Y, C. The 2DFIR filter does not understand subsampled data and it only sees a second fully sampled color plane C. Consequently, the filter would smear the Cb and Cr planes onto each other.

What I was suggesting was that:

4:2:2 (seq or par) -> VIP_ColorPlaneSequencer (splitter) -> 1 + 2

1) FIR on Y (1 seq) -> Fifo(*) -> 3

2) FIR on Cb,Cr (2 seq) -> Fifo(*) -> 4

3 + 4 -> VIP_ColorPlaneSequencer (join) -> 4:2:2 (sequence or parallel)

*Fifos may be necessary in case of throughput issues
