End-to-End Architecture
Cloud-Edge Hybrid • WAN Unicast • LAN Multicast
- On-Site DVB Hardware0
- Viewers/Channel1,000+
- Deployment< 1 Hour
- Cost Savings70-85%
Signal Path: Professional SAT>IP Servers at SATLINE datacenters (dish farms, DVB processing) → Optimized TCP Unicast over WAN → SAT>IP Servers Pro appliance on-site → Multicast IPTV + VOD distributed across your LAN.
Key Benefits
- No antennas or DVB racks on site
- Fast rollout: under 1 hour
- No coax – IP only infrastructure
- Local VOD – zero external traffic
- Lower TCO: 70-85% savings
- Unlimited scalability
Architecture Features
- Hybrid cloud-edge design
- WAN unicast (TCP-interleaved)
- LAN multicast (IGMP v2/v3)
- QoS-aware streaming
- VLAN segmentation
- Enterprise-grade reliability
Multicast IPTV Benefits
Enterprise-Grade Bandwidth Efficiency • Unlimited Scalability
Each channel is injected once into the LAN as a multicast group. Ethernet switches replicate traffic only to ports where TVs have joined using IGMP, keeping backbone utilization flat even as viewership scales.
Bandwidth Efficiency
- 50-150 channels: 300-600 Mbps total
- Per-channel: 2-7 Mbps (vs 45-55 Mbps MPTS)
- 80-95% less bandwidth than MPTS
- 100+ channels fit in 1 Gbps plan
- Backbone traffic stays flat
- Scales by channels, not viewers
Scalability
- 1,000+ viewers per channel with zero additional multicast bandwidth
- No extra multicast bandwidth
- Works for 100 or 5,000+ rooms
- Predictable bandwidth usage
- No traffic spikes during peak viewing
- Horizontal scaling support
Key Takeaway
SATLINE scales by channels, not by viewers — stable, predictable, and extremely efficient for hotels, resorts, campuses, hospitals, and ships. By contrast: Traditional MPTS pulls a full transponder (~45-55 Mbps) regardless of how many channels are needed, while SAT>IP Server Pro pulls only the requested channel at 2-7 Mbps — an 80-95% reduction per stream.
Bandwidth Comparison
MPTS vs SAT>IP Server Pro vs Optimized Unicast
Bandwidth Usage Comparison
Traditional MPTS
- Full transponder: ~45-55 Mbps
- Full transponder pulled regardless of channel count
- Unnecessary backbone load
- Higher latency
- Wasted capacity
SATLINE SAT>IP Server Pro
- Exact channel: 2-7 Mbps
- Ultra-low latency
- 80–95% bandwidth reduction vs. MPTS
- Optimized TCP interleaving
Optimized SATLINE Unicast: 100+ channels fit into a 1 Gbps broadband plan via TCP interleaving, ideal for hotels and buildings.
Local Multicast Distribution: Each channel is injected once into the LAN and replicated only to TVs that request it, keeping backbone traffic flat regardless of viewer count.
