1 High grade SFN adapter

Accurate MIP inserters

Proven robustness and interoperability
Remote control of every single transmitter
independently :
- Power, frequency oset, delay, ... conguration
- No need to drive for hours to adjust SFN
DVB-T, DVB-H or DTMB multi-standards capable

2 Secured redundant 1+1 SFN Adaptation

SFNguard™ solution for SFN adapters

Patented 1+1 redundancy mechanism without additional equipment
Seamless operation of SFN adapters :
- Guarantied MegaFrame synchronization
- Identical and synchronized MIP packets
- SFN adapters seamless switchover
- Hot swap of defective unit during operation

3 SFN streams Distribution over IP

FastCaster™ : TS over IP Gateway

Re-use of convenient IP networks:
- Low CAPEX, reliable distribution
- Optimized OPEX, simple management
Preservation of SFN over IP
- Accurate bit rate adaptation
- Compensation for IP network jittering

4 Multiple SFN streams Distribution over IP

GigaCaster™ : Dense TS over IP Gateway

Able to process up to 8 MPEG2 Transport Streams in parallel (up to 16 in 1RU 19')
Gigabit Ethernet interface to address IP backhaul
Preservation of SFN over IP
- Accurate Bitrate adaptation on each TS
- IP network jitter compensation on each TS

5 Redundant SFN distribution paths

SynFoNizer™ : "Seamless SFN"

Patented seamless switch between two distinct distribution networks
Enables redundant distribution paths for SFN transmitters
Even if I-ary and II-ary paths have dierent delays, SFN data is kept synchronized in case the main distribution path is broken

6 SFN Modulators / Exciters

NetMod™ broadcast modulators

Full SFN, including optional MIP tables parsing
Valuable integration in Transmitters with
- SNMP, HTTP control
- ASI / IP / satellite / GPS antenna inputs
DVB-T, DVB-H or DTMB multi-standards capable

7 SFN Network Test and Monitoring

The "Omnitoring" solution

DiviCatch™ Field testers:
- Drive tests (geolocalization)
- SFN network Installation and maintenance
CastXplorer™ Network Monitoring Probes
- QoS network assessment
- SFN Network stability
- SFN jitter and network trend detection

8 Centralized Supervision and Monitoring

Fully manageable SFN Network

Remote control from central NMS of
- Head-End system
- Distribution network
- Transmission chain
- Probes
Continuous feedback and instant alarms from the field using Monitoring probes
