Case study : GOtv
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

10. Primary Distribution

12. So by default, 2 separate Satellite feeds should be used:
one for DTH + one for DTT Primary Distribution
