ASIIPGuard

Innovative ASI switch
ASIIPGUARD IS ENENSYS INNOVATIVE AND DENSE ASISWITCH THAT ENABLES AUTOMATIC 2:1 OR 3:1 SWITCHREDUNDANCY OF ASI AND IP FEEDS. AS AN OPTION, ITCAN PROVIDE SEAMLESS SWITCHING CAPABILITIES OF
IDENTICAL MPEG-2 TS, T2-MI OR BTS STREAMS.

APPLICATIONS• 2:1 or 3:1 automatic switch redundancy• Automatic redundancy of ASI and IP feeds• Switching over IP feeds and delivering over ASI• Seamless switch-over of identical TS• Seamless switch-over of T2-MI & BTS streams• Seamless switch-over of SFN/DVB-T streams

AUTOMATIC 2:1 OR 3:1 ASI SWITCH
The ASIIPGuard aims at providing automatic redundancy switch between
2 or 3 MPEG-2 Transport Streams according to the validity of the incoming
streams. Upon ETR290 errors, SFN errors, T2-MI, BTS errors or advanced
MPEG-2 TS errors, ASIIPGuard switches automatically from the faulty
input to the valid input.

BENEFITS• Dense solution with up to 6 ASI switches in 1U• Cost eﬀective solution:• 3:1 switch avoid to cascade two 2:1 switches• Multiple ASI and IP outputs to avoid splitters• Includes TSoIP function• Avoid TV black-out in SFN (and MFN in DVB-T2)• Seamless switch-over with delayed source• Multi-standard applicable (DVB, ATSC, ISDB,...)• Video agnostic: MPEG-2 or MPEG-4/H.264• Maintain service continuity for ASI and IP inputs

VERSATILE ASI AND IP INPUTS/OUTPUTS
Additionally, the ASIIPGuard can support up to 6 switch functions in thesame chassis providing 6 ASI switches in 1RU. As an option, it can switch
over ASI and IP feeds and outputs the selected input over ASI and IP.

SEAMLESS SWITCHING
The ASIIPGuard strives to provide a true seamless switch-over under thefollowing conditions:• In DVB-T Single Frequency Networks, the ASIIPGuard enables aCHARACTERISTICS• Automatic switch between 2 or 3 MPEG-2 TS• Seamless switching between 2 or 3 T2-MI streams• Seamless switching between 2 or 3 BTS streams• Up to 6 ASI switch in the same unit
• Switch between 2 or 3 ASI feeds• Switch between ASI feeds and IP feeds• IP outputs with ProMPEG CoP#3• Up to 4 ASI outputs or 3 ASI and 2 IP outputs• Peering mode to peer 2 ASIIPGuard• Flexible switching conditions conﬁguration• ETR290 based switching conditions• MIP, T2-MI and advanced TS switching conditions• ATSC1.0 and ISDB-T switching conditions• Bypass mechanisms for ASI and IP inputs• Real-time monitoring of incoming streams• Easy to use web-based GUI• Full SNMP v2 support

unique, automatic and secured SFN seamless change-over between
two ENENSYS SFN Adapter (MIPDVB for HDc) with the patented
technology SFNguardTM. This is mandatory to guarantee SFN broadcasting, where all DVB-T SFN transmitters must receive the samecontent to transmit it over the same frequency at the very same time.

• In DVB-T2 & ISDB-T/Tb, the ASIIPGuard can seamlessly switch-overredundant T2-MI and BTS streams. It can provide an automatic 1+1
redundancy mechanism between two gateways. Combined with theENENSYS DVB-T2 or ISDB-Tb gateways, the ASIIPGuard oﬀers a safeand seamless redundancy solution for SFN and MFN broadcasting.

• MPEG-2 Transport Streams can be carried over redundant links. Bothlinks may have diﬀerent delays (satellite-IP, IP-IP). The ASIIPGuard
enables to realign both streams to seamlessly and automatically switchfrom ASI or IP input to ASI or IP input. Thus, changing-over one network
to another network as no eﬀect on the audiovisual content carried over
MPEG-2 TS. This applies also for T2-MI or bTS streams delivered overdiﬀerent network paths.
