6.3.11. Captions are not Being Encoded Correctly
If there is no option in the captioning/teleprompter software for the Evertz encoder, configure your
software to communicate with an EEG 270, EEG 370 or EEG 470 model Smart Encoder. The Evertz
caption protocol is compatible with these units.
Make sure that the caption encoder unit is set to the correct video type, 525-60 for component NTSC.
Check your serial port communications settings. Make sure that these are identical between the caption
encoder and the attached captioning computer.
Check that the unit is receiving data from the serial port or modem.
If certain accented and special characters do not display correctly, this is likely the fault of the caption
decoder being used to display the captions. Some decoders do not support the entire character set for
captions.
Certain teleprompter software packages have been known to not encode accented characters correctly.
Please contact your software provider for possible updates before contacting Evertz technical support.
6.3.12. How Can I Block Upstream Captions?
Depending on the user’s specific needs, there are several ways to accomplish this. If all upstream
captions are to be blocked, this can be accomplished by one of the following methods:
•
Change the Upstream Source front panel controls. See section 3.4.4.
•
Issue the serial port commands ^A6 F1 and ^A6 F2 to place Field 1 and Field 2 into NULL
STATE. See section 4.3.13.
If only particular caption services are to be blocked, such as Text Channel 2:
•
Change the setting of the Pass Upstream menu controls. See section 3.4.4.4.
•
Issue the ^A6 (NULL STATE) serial command, ex:^A6 T2 to place Text Channel 2 in NULL
STATE. See section 4.3.13.
•
To block specific XDS packet types, see the ^AP command in section 4.5.2.
6.3.13. How Can I Pass Upstream Captions?
If upstream captions are being blocked, the user’s captioning software might have failed to relinquish
control of the encoder so upstream captions may pass.
If captioning software is leaving the unit in DIRECT STATE or REAL TIME STATE or NULL STATE
when it is sitting idle, this issue must be resolved in the caption software itself.
6.3.14. When Should I Use “Reset to Factory Defaults?”
Factory Reset should not be used lightly. It is intended primarily for use when Evertz technical support
personnel are assisting an operator with a problem. The Factory Reset could also be used when the
encoder is placed in a particular undesirable mode of operation and the operator is highly unsure as to
how to resolve the situation. Note that any special features that have been enabled by the operator,
such as baud rate settings, will need to be reconfigured after a Factory Reset.
