1 International multiplex (20 Mbps) + 15 regions (10 Mbps each)
Without T2Edge : Build complete T2 multiplex with international and regional content for each region
•30 Mbps * 15 = 450 Mbps of satellite capacity
With T2Edge : International content is send only once
•20 Mbps + 15*10 Mbps = 170 Mbps
•Saving 280 Mbps of satellite capacity
Primary Distribution over DTH network
So by default, 2 separate Satellite feeds should be used: one for DTH + one for DTT Primary Distribution
