15 years agoAh yes thanks, if I do a search It's hidden away in table 5-8 right at the end of the scaler section. Progressive only :( ah well its not my money :)
I have a clipper set up to 720x540 and it *seems* to be clipping ok - but then with a bars test pattern its hard to tell if its getting the vertical right! The documentation states: "Either. Interlaced inputs are accepted but are treated as progressive inputs" So I'm guessing that if I feed in a 576i signal and I tell it to clip 500 it will clip 288 from field 0 (the whole field) and then 212 from field 1? Does the clipper then output a progressive control packet? If thats how it works I shall be trying 720x220 as suggested by vgs. I imagine If i feed the CVO with progressive while set to interlace output it will go awfully wrong ;) but I will give it a try. Thanks for your comments!
