Transcoders
For the remainder of this manual, we will use the term port for a physical input/output port (such
as ASI or Ethernet), and stream for a transport stream present in the port. ASI ports support only
one stream, while Ethernet ports support multiple streams. A transport stream can have one or
more programs. In this manual, we will use the words program and service interchangeably.
Redundancy Options
The IP inputs in the unit can be configured to support transport stream redundancy. This means
that the unit can be configured with a “primary transport” and a “backup transport”. If the
primary transport disappears, the unit may be set to automatically switch to the backup transport,
after a configurable timeout. The redundancy function has the following features:
•
Transport stream redundancy can be set to “Manual” or “Automatic”. In “Automatic”
mode, the unit will switch to the backup stream after a configurable timeout, if the
primary stream disappears. In “Manual” mode, the switch has to be performed by the
operator.
