DTTV / SFN solutions


A unique end-to-end solution for efficient DTTV broadcasting over SFN networks

 

DVB-T SFN solution


SFN adapter ASIGuardII SFN over IP SynFoNizer DVB-T Exciter EdgeProbe

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
 

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

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

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

SFN Network Test and Monitoring

The "Omnitoring" solution
  • DiviCatch™ Field testers:
    • Drive tests (geolocalization)
    • SFN network Installation and maintenance
  • EdgeProbe Network Monitoring Probes
    • QoS network assessment
    • SFN Network stability
    • SFN jitter and network trend detection

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
