PRSD-4069 series HD/SD SDI broadcast "smart" changeover |
The PRSD-4069 broadcast changeover protects a complete channel providing HD/SD SDIembedded video/audio support. Electrical and optical outputs. A pass-through relay on power-down condition connects the "A" input with the program output. HDMI monitor output with 8-channel audio level meter OSD bargraph. Optional redundant PSU.
The changeover switching occurs between the main ("A") and the secondary ("B") lines in automatic or manual mode, under local or remote control.
In automatic mode the "A" and "B" signals are analysed to be selected for the program outputs. The GPO lines report the changeover status.
Main features
- two program inputs: A and B
- four program outputs
- relay bypass on the output #1
- optical ouput #4 (SFP module)
- HDMI monitor output with audio level meter OSD
- automatic "smart" A/B switching by signals' parameters analysis
- manual A/B override from local panel, web interface or GPI
- event log available through web interface
- GPI status ouputs ("A", "B", "A fault" and "B fault")
- up to 30 seconds of timing skew between the A and B signals
- built-in HTTP server, SNMP management, alerts by e-mail

Analysed signal parameters (video)
- signal loss condition
- EDH/CRC errors
- video content freeze
- HD/SD SDI video content amplitude anomalies
Analysed signal parameters (audio)
- SDIembedded audio group loss
- audio level anomalies relative to the "B" input
- audio level drop below the "silence threshold"
