ASIIPGuard

ASI/IP switch for digital TV signals

ASIIPGuard is ENENSYS innovative and dense switch that enables automatic 2:1 and 3:1 switch redundance of ASI and IP feeds. It can provide seamless switching of identical 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

Highlights

Flexible ASI & IP solution

ASIIPGuard is the most flexible switch on the market. It allows you to mix IP and ASI interfaces for your 2:1 or 3:1 redundancy needs.

Secure your distribution links

ASIIPGuard synchronizes identical MPEG-2 TS streams coming from different links with different propagation delay. This avoids any DTT audio & video glitches when errors occur on distribution links (satellite, IP, microwave...)

Unique seamless switch-over for DVB-T/T2

Used with ENENSYS' SFN adapters or DVB-T2 gateways, ASIIPGuard enables automatic and secure SFN seamless switch-over.

2:1 and 3:1 redundancy

ASIIPGuard enables switching between 2 or 3 sources, based on configurable criteria (ETR290 1/2/3 and advanced audio/video conditions) allowing you to provide the best experience to your customers.

Bypass for ASI and IP

In case of power outage, a bypass (or passthru) feature keeps the signals available on ASIIPGuard's IP & ASI outputs to ensure 100% service availability.
