15.9. 4K Video Passthrough Support

The Deinterlacer II IP core offers different approaches for 4K video passthrough based on your deinterlacer configuration..

To determine the best approach for your deinterlacer configuration, refer to the table below.

Table 47.  Appropriate Approaches for 4K (SDR and HDR) PassthroughFor Bob and Weave configurations, 4K HDR and SDR passthrough is natively supported. However, if you observe that the required fMAX (e.g. 300 MHz for 2 pixels in parallel) cannot be reached, then use approach B to switch the deinterlacer to 4 pixels in parallel and half the fMAX.
Deinterlacing Algorithm Cadence Detection Algorithm Approach
Bob Not applicable None — 4K passthrough supported natively
Weave Not applicable None — 4K passthrough supported natively
Motion adaptive Any settings Approach B — 4K passthrough not supported natively; use two Switch II IP instances
Motion adaptive high quality 3:2 and 2:2 detector with video over film Approach A — 4K passthrough supported natively but conversion for fMAX required
Other settings Approach B — 4K passthrough not supported natively; use two Switch II IP instances
