Failover Mechanism:

1. What conditions will trigger the failover?

DVB 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
• Transport stream protection for On Air video servers
