Channel Configuration Guide
Upgrading to the Output Server 2 Service
Before upgrading a playout server to Output Server 2, Output Server 1 must be uninstalled.
This can be done as part of the upgrade process.
The iTX installer will convert the current channel configuration from Output Server 1 to
Output Server 2. However, the channel name is not migrated as that information is stored in
different locations on each service. To support the I/O Device Controller (which was not
present for Output Server 1), you need to select your required playout type. Therefore,
during the upgrade the iTX Channel Config dialog appears so that these details can be
entered. It is also possible make changes to the channel details, as required.
Playout timing
Output Server 2’s playout is frame accurate, which means a
scheduled item may playout earlier on the Output Server 2 backup
channel compared to the Output Server 1 main, but the difference
should be marginal.
Live pass-through delay
The live pass-through delay was redesigned for Output Server 2
and is different to Output Server 1. It may be possible to
synchronize the live pass-through for an Output Server 1 main and
an Output Server 2 backup by altering the delay on both channels.
For information on changing the output buffer and time delay on
Output Server 1, see the iTX System Administration Guide.
For information on changing the Channel Delay on Output Server
2, see
Audio output types
On Output Server 2, the
PCM (Auto)
audio output type will assign
16 channels to the track, even if not all of the channels are
required. Any unused channels will be automatically set to mute.
See
About Audio Output for Output Server 2
on page 49 for more
information.
SCTE 104
Output Server 2 only supports enhanced SCTE 104. Therefore, the
Output Server 1 main will also need to be configured to use
enhanced SCTE 104.
For more information on enhanced SCTE 104 configuration for
Output Server 1, see the iTX System Administration Guide.
For more information on SCTE 104 configuration for Output Server
2, see See
Configuring a Channel to Process SCTE104 Messages
NTSC SD field order
Output Server 1 and Output Server 2 handle the field order for
NTSC SD assets in different ways. Output Server 1 often
required user intervention to reverse the field order on a per-
asset basis, while Output Server 2 is able to interpret this
information from the media itself. This can cause problems
when trying to playout assets that have been altered on a
mixed Output Server system.
