iTX Output Server 2

Launch Guide

10 Route newly commissioned Output Server 2 master channel to air.

11 Failover the Output Server 2 slave, so the channel plays out from the Output Server 2

master.

The selected channel is now running Output Server 2 for both master and slave.

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 master and Output Server 2 slave side by side.

These differences do not affect when items are played out to air.

Playout timing Output Server 2’s playout is frame accurate, which means a

scheduled item may playout earlier on the Output Server 2 slave

channel compared to the Output Server 1 master, 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

Configuring the Channel Details, on page 16.

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 Configuring Audio Metadata and Output on page 19 for more

information.
