Configuring channels
When Fixed Availability Windows is selected, an operator specifies both the date and time for
the start and end of the break window. When this is not selected, an operator specifies start
and end times for the break window that are relative to the start time of the sequence.
UTC Offset
If your iTX system is using a UTC time reference, you can set up iTX to display local time on
layout features (e.g. the Schedule Grid or Event Editor). To do so, you specify the required
offset (in hours) in the UTC Offset box. You may enter any value that is a multiple of 0.5 hour.
For example: 1 hour; 1.5 hours; -2 hours.
Note:
•
For this setting to be effective, the channel must receive the time in UTC from the
Time Service.
Daylight Saving Time Boundaries
To enable iTX to automatically apply daylight saving time (DST) to a channel, select
Automatically adjust for Daylight Saving Time. iTX adds an hour to the channel's local time
(with the UTC offset, if applicable) between the DST Start and DST End boundaries you set.
•
To set the DST Start, select the date DST starts; then select the time it starts, in the
channel's local time (with the UTC offset, if applicable).
•
To set the DST End, select the date DST ends; then select the time it ends, in the
channel's local time (with the UTC offset, if applicable).
For example, if DST starts and ends at 01:00 UTC:
•
If the channel's local time has no UTC offset, select a DST Start and DST End time of
01:00.
•
If the channel's local time has a UTC offset of +4, select a DST Start and DST End time
of 05:00.
Note:
•
For this setting to be effective, the channel must receive the time in UTC from the
Time Service.
Frame rate (Output Server 1 only)
In the Frame rate box, select the required speed in frames per second (fps) of the video output.
Note that, for progressive scanning, the frame rate equals the field rate; so, for example, the
frame rate required for a 720p video output is 50 or 60 fps.
Note:
•
This section is only available to channels running the Output Server 1 service. For
channels running Output Server 2 see the Output Server 2 Channel Configuration Guide.
