16 years agoHi,
Your FAE should be asking for the reference design called V2. This reference design contains a beta version of the interlacer although this is not a full interlacer and it just drops every other line. When processing interlaced video, the mixer, like many VIP cores, will do the processing on a field basis. In order to do the mixing, you probably will have to ensure that F0s are properly synchronized together because the mixer will just use whatever is coming in. The disclaimer note on the VIP guide means that when specifying (x,y) coordinates for the top-left pixels you have to divide y by 2. The double buffer supports interlaced video but the triple buffer does not. If you turn on the drop or repeat checkboxes you may end up with a stream that contains successive F0s or successive F1s. vgs
