What is VSAT DVB-RCS?
DVB = Digital Video Broadcast
RCS = Return Channel via Satellite
Open standard VSAT technology
ETSI Standard EN 301 790 established for interoperable VSAT
networking in 2001 as worlds first two-way satellite standard
There are approximately 100 fully compliant DVB-RCS Hubs &
20, 000 terminals worldwide
Satlabs: Forum led by ESA grouping stakeholders of DVB-RCS
(over 20 members) to ensure standard compliant & interoperability
DVB-RCS Availability:
DVB-S
DVB-S2

Why Use DVB-RCS?
6
Open Standard IP based VSAT Technology:
- Forward data link from gateway to remotes up to 80mb/s
- Return data link from remotes to gateway 2 – 4 mb/s
- Multi-vendor competitive environment
- Proven Interoperability which leads to low cost equipment
- Ease of adding new terminals to network &, Scalable Hub
- DVB-RCS supports current and upcoming IP services
Fading & Interference countermeasures
- Higher availability of terminal connectivity
- Optimized use of satellite bandwidth
DVB-S2
Latest Platform
Technology
Advanced Coding Schemes
- CCM – Constant Coding Modulation
- VCM – Variable Coding Modulation
- ACM – Adaptive Coding Modulation

DVB-S2: Leading DVB-
RCS Technology(ETSI: EN 302 307)
Wide range of modulation schemes (QPSK, 8PSK, 16APSK and
32 APSK modulation)
Variety FEC coding (LDPC): 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5,
5/6, 8/9, 9/10
Supports 3 modes of modulations: CCM/VCM/ACM
Provides Ability to Dynamically Change Modulation: VCM/ACM
Improves BW efficiency by 30% - 50% over DVB-S in CCM
