ASIIPGuard ASI Switch  

DVB-ASI Redundant Automatic Bypass Relay Switch with up to 6 independent 1+1 switching modules. Multichannel DVB-ASI Transport Stream Failover Switch automatically switches to the secondary TS input if problems are detected with primary input. Monitors up to six channels in real time.

ASIIPGuard is an innovative and dense redundancy switch which enables automatic 2:1 and 3:1 switch-over of ASI and TS over IP feeds. It provides seamless switching between two or three TS, T2-MI or BTS streams.

 

Features:

  • Automatically switches to the back-up transport stream source when problems occur
  • Switching occurs on either transport stream sync loss or up to 8 PID losses
  • Encoding Compatible with DVB-ASI (EN50083-9) standard
  • Up to 6 independent 1+1 switching modules in 1 RU 19 inch chassis
  • Built-in real time transport stream monitoring
  • Input and Output bit-rate up to 160 Mbps on each switch module
  • Automatic or manual switch mode
  • TS sync loss and PIDs loss as switching condition
  • Mechanical Bypass Relay to output in the event of power failure
  • DC 12V backup power supply
  • Remote control, supervision and by SNMP and HTTP Web

Applications:

  • Transport stream failover protection in cable head ends
  • Transport Stream Protection in Teleports
  • Transport Stream Protection for On Air Video servers

Features:

  • Switching Capabilities
    • 2:1 automatic redundancy switch
    • 3:1 automatic switch - Option

    • MIP/T2-MI alarms
    • Video, audio, service bit rate
    • Advanced TS errors
  • Seamless switching
    • Maintaining DTT transmitters
    • synchronization to avoid TV blackout
    • DVB-T/SFN, DVB-T2,ATSC & ISDB-Tb applicable
  • Inputs resynchronization
    • Realign the stream stemming from network pathss with different delays to avoid glitches
  • Service availabilty
    • Real-time monitoring of incoming streams, Web-based GUI
    • Full SNMP v2 support
    • SNMP v2C INFORM

Applications:

  • 2:1 or 3:1 automatic switch redundancy
  • Automatic redundancy of ASI and IP feeds
  • Swtiching 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

Benefits

  • Cost effective solution:
    • 3:1 switch avoid to cascade two 2:1 switches
    • Multiple ASI and IP outputs to avoid splitters
    • Includes TSoIP
  • 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
  • Avoid video & audio glitches in case of network failures
  • Unique 3:1 redundancy solution on the market
