15.8. Avalon-ST Video Support
Progressive content of all resolutions, including 4K content, will be passed through unchanged.
The Deinterlacer II always passes through user packets. The Deinterlacer II IP core contains an embedded Avalon-ST Stream Cleaner IP core for motion adaptive configurations, which you may disable. It is included to ensure that there is no possibility of malformed input packets locking up the deinterlacer.
You may disable the embedded stream cleaner but this is only recommended if a stream cleaner already exists in the system upstream of the deinterlacer or if you select one of the simpler algorithms (Vertical interpolation (“Bob”) or Field weaving (“Weave”), which have complete resilience to all possible malformed inputs.
