VPUs and Scaling engines
Understanding VPU concept is the key for optimized performance.
Concept : Video Processing Units⚓
VPU
VPU are the main processing components of LivePremier. They create the layers and allocate them to one or multiple outputs.
Legal : Important⚓
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.
