DTTV / SFN solutions


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

dvb-t solution


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

High grade SFN adapter

Accurate MIP inserters
  • Proven robustness and interoperability
  • ASI and IP inputs and outputs
  • Remote control of every single transmitter
    independently :
    • Power, frequency offset, delay, ... configuration
    • No need to drive for hours to adjust SFN
 

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

Seamless switch

ASIIPGuard™ : "Seamless SFN"
  • Seamless switch between 1+1 SFN adapter over ASI
  • Seamless switch between two distinct distribution networks over ASI
  • Enables redundant distribution paths for SFN transmitters
  • Even if primary and secondary paths have different 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
IPGuard™ : "Seamless SFN"
  • Seamless switch between 1+1 SFN adapter over IP
  • Patented seamless switch between two distinct distribution networks over IP
  • Enables redundant distribution paths for SFN transmitters
  • Even if primary and secondary paths have different delays, SFN data is kept synchronized in case the main distribution path is broken

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 or DVB-T2 multi-standards capable
