4.14.2.2. Caption Shift Up Lines
This control enables the user to set the baseline of the CEA-608 captions up from 2 to 4. The
Caption Shift
Down Lines
control is identical. For the sake of brevity, only
Caption Shift Up Lines
will be discussed in
the manual.
4.14.3. Test Message Enable
4.14.3.1. CEA-608 Test Msg
The
CEA-608 Test Message
is used to test all fields and outputs of the MIO-CCE-4K/3G. This function
will provide test messages in Field 1 and Field 2 for the SD-SDI output and transcoded test messages on
the HD/3G output. If the Translator is configured appropriately, the CEA-608 data will also be translated to
CEA-708 data. This function is helpful during troubleshooting procedures.
4.14.3.2. CEA-708 Test Msg
The
CEA-708 Test Message
provides captions on Services 1 through 4. Each service shows a different
caption test pattern. This feature helps users test downstream equipment such as HDTV decoders and
ATSC encoders.
4.14.4. Service Missing
The Service Missing Duration provides the user with controls to set the timeout period before a caption
service alarm is raised. There are 15 sliders in this panel which allow the user to set controls for services
608 CC1 to CC4, 608 TXT1 to TXT4, 608 XDS and 708 Svc 1 to Svc 6. The timeout period is displayed in
minutes with a range from 0 minutes to 8.5 minutes. These may be configured to assert the GPOs or to
generate a Fault Trap if the duration period is exceeded.
4.14.5. CC Misc System Control
4.14.5.1. DST In Effect
This control is used to indicate whether Daylight Saving Time (DST) is currently in effect. The DST setting
will be used to calculate the current local time, and to set the DST flag in XDS packets.
When set to
off
, Daylight Saving Time compensation will not be applied. When set to
on
, Daylight Saving
Time compensation will be applied to the time.
4.14.5.2. DST Observed
The
DST Observed
control allows the user to specify whether Daylight Saving Time is observed in their
locale. This is used to calculate the current local time, and to set the DSO flag in XDS packets. For regions
that observe Daylight saving time, the DST Observed setting must be set to
On
, and for regions that do not
observe Daylight saving time, the DST Observed setting must be set to
Off
.
4.14.5.3. Timezone
This option allows the user to set a time zone offset between the UTC time and the Local time. This time
zone offset will be added to the UTC time along with the Daylight Saving time correction to obtain the Local
time. Time zones are normally in one hour or 30 minute increments and can be + or – from UTC. (Time
zones east of Greenwich are +, and time zones west of Greenwich are -).
