Mute Audio on General Alarm

IPTV Mute Audio on General Alarm

Key Features :

•  With koovik-mute, all connected set-top boxes (STBs) will mute their audio output when an external event
   (such as General Alarm) occurs.
•  The koovik-mute is realized through a digital I/O unit connected to the LAN.
•  The koovik IPTV gateway monitors the I/O unit via SNMP protocol.
•  When the digital I/O goes to "Logic 1", the koovik IPTV middleware mutes all connected set-top boxes.
