Two Channel Real Time MPEG-2 SMPTE 310M Failover Switch with Real Time and Sophisticated Transport Stream Monitoring. Complete remote management, setup, and error reporting via web based interface. Created for satellite, cable, and other content where N+1 redundancy in signal paths is crucial.

Real Time Transport Stream Demultiplexer(Tuner) for real time forwarding of selected programs (PIDs) from Complex Multiprogram Transport Streams. Ideal for pulling out only selected programs from complex satellite feeds.

Continuous SMPTE 310M (MPEG-2 Transport Stream) Playback with (SMPTE 310M) ATSC output for use as Failover Server when primary station path is unavailable.

Standard Features:

• Automatic switch to secondary input
• Intelligent Real Time Transport Stream Monitoring
• Web interface for remote configuration management

• Access Control to restrict unauthorized users

• Mechanical Bypass Relay connects primary input to output in the event of power failure

• Configurable delay to switch from primary to secondary input

• Carrier Detect, Synchronization and Bitrate status on active input

• Configurable automatic switch back to primary

• 1 RU rackmount server

• Logging history indicates switch state with date and time stamp

• Green and Red Status indicators to indicate active and inactive inputs

• RoHS compliant server with redundant power supply

  
  
  

Failover Mechanism:

1. What conditions will trigger the failover?

ATSC Guardian will monitor carrier detect and the presence of sync bytes in the stream.



2. Are the conditions user-programmable?

The user can program the length of time that both carrier detect and presence of sync. combined is monitored before a failover. This is programmable from 0 to 20 seconds.

Applications:

• Transport stream failover protection in cable head ends
• Transport stream protection in Teleports
