ASIIPGuard
1+1 Smart switch for ASI/IP redundancy
ASIIPGuard is ENENSYS innovative and dense ASI/IP redundancy switch that enables automatic 2:1 or 3:1 switch redundancy of ASI and IP feeds. As an option, it can provide seamless switching capabilities between two or three MPEG-2 TS, T2-MI or BTS streams.
Highlights
Automatic 2:1 or 3:1 ASI/IP 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.
Seamless switching
The ASIIPGuard offers seamless switching capability between 2or 3 identical MPEG-2 TS, BTS, T2-MI streams that are carried over ASI or IP-based networks with different delays: it aligns streams to perform a seamless switching. When combined with ENENSYS gateways, ASIIPGuard can provide a seamless switch-over between two gateways for DVB-T/T2 & ISDB-Tb networks.
100% Service Availability
By default, the ASIIPGuard offers an ASI bypass mechanism in order to enable 100% of service availability in case of power outage. As an option, the IP bypass is also available.
High Density Solution
Thanks to the innovate Enensys design, up to 6 ASIIPGuard hot-swap modules can be inserted in a chassis. This allows for up to 6 redundancy switch in a 1U size equipment.
Applications
- 2:1 or 3:1 automatic switch redundancy
- Automatic redundancy of ASI and TS over 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
Other Benefits

- Video agnostic: MPEG-2, MPEG-4/H.264 or HEVC/H.265
- Multi-standard applicable (DVB, ATSC, ISDB,…)
- Outputs synchronization of several ASIIPGuard with peering feature
- Real-time monitoring of incoming streams
- Up to 6x ASI switches in 1U
