Notes

  1. S = Standard Channel (scaler input with resizing and retiming), LL = Low Latency Channel (No scaling.  If LL is used, output timing is defined by LL input timing)
  2. Additional Blending Techniques include: Clamp Sum Blending, Dynamic Contrast, Dynamic Alpha (Symbology LSB encoded alpha, Blue-encoded alpha).
    Contact Westar if you are interested in these blending techniques or others on any of our video combiner products.
