VIP scaler - dare I say Interlace?

Hi,

I am assuming that you generator is a proper Avalon-ST Video Generator and that it generates a valid control packet before each interlaced field packet.

If you feed in a 576i signal and tell the clipper to clip to 500 things could go horribly wrong because the clipper will attempt to clip your input fields to 500 which if higher than what they actually are.

This is what "Interlaced inputs are accepted but are treated as progressive inputs" means. The clipper will consider each field as an individual frame so the heights should be field heights not frame heights (cf VIP example design, there is a clipper before the deinterlacer).

I think the scaler is exactly the same and can scale interlaced fields but Jake could be right when he mentions that it will output an incorrect control packet after the scaling.
