6.3 LivePremier Processing
VPUs and Scaling engines
The main processing components of LivePremier are the Video Processing Units (VPU). VPUs create the layers
and allocate them to one or multiple outputs. Understanding VPU concept is the key for optimized
performance.
Each VPU contains 8 source links and 8 outputs links.
Capacity 1 uses one link and capacity 2 uses two links. Each VPU supports:
- 8 mixing layers (or 8 pairs of split layers) spread over 8 outputs, in capacity 1.
- 4 mixing layers (or 4 pairs of split layers) spread over 4 outputs, in capacity 2.
