configuration.
See Upgrading to the Output Server 2 Service on page 17.
5 Start Server Controller on the Output Server 2 backup and confirm the following
configuration:
• On the instance of I/O Device Controller for the channel, check the Reference input
is correct.
See Setting a Reference, Frame Rate Family and Output Timing on page 29.
• On the instance of Output Server 2 for the channel, check the Resolution is correct.
• Apply any other configuration, as required. Backup channels should mirror the
configuration of their main, although when running a mixed Output Server system
some differences in configuration may be required.
See Operating a Mixed Output Server System , on page 16 for differences in
configuration.
See Output Server 2 Channel Configuration on page 29 for more information on
channel configuration.

Operating a Mixed Output Server System
When running a mixed Output Server system, consider the following differences in
behavior between the two video engines:
Feature Comment
Internal captions Output Server 2 has improved rendering for internal captions. As
such you may see some differences in captions between the two
video engines. For example, outlines and drop shadows are clearer
on Output Server 2.
Cue and commit timings The timing for cueing and committing events was redesigned for
Output Server 2 and it does not mirror Output Server 1.
The differences are visible on the schedule grid when viewing an
Output Server 1 main and Output Server 2 backup side by side.
These differences do not affect when items are played out to air.
