Press Release Summary: ENENSYS strengthens SFN Adapter 1+1 switch-over, and more
generally, SFN broadcast consistency with its new feature SFNguard, where two SFN
Adapters communicate together in order to preserve transmitters SFN synchronization.


Press Release Body: Unlike Multiple Frequency Network (MFN), Single Frequency
Network (SFN) topology is much more demanding. Within an SFN network, timing as well
as transmission parameters are provided by the SFN Adapter to each transmitter
belonging to the same SFN cell. In case of failure of the SFN Adapter, switching
automatically to the spare is not sufficient. Indeed, this will cause the modulators
to de-synchronize during several seconds, resulting in a TV blackout.


"SFNguard is a unique and innovative synchronization mechanism ensuring both SFN
seamless switch-over and reliable end-user experience. SFNguard option is available
for both DVB-T/H and Chinese DTMB SFN Broadcast." said Olivier MILET, Head-End
Product Manager. "With SFNguard, ENENSYS confirms its position as an expert in SFN
Broadcast".
