Emergency To Air
In the event of a background video failure an emergency message can easily
be sent to air using this command. The emergency image must be stored in
the image library under filename V000.oxt.
When Emergency To Air is selected, Key Layer 1 on the program output
channel is faded down over 25 fields. Image V000.oxt is then loaded and
faded up over a further 25 fields.
Emergency From Air
When Emergency From Air is selected, Key Layer 1 on the program output
channel is faded down over 25 fields and the previous image is restored, but
not faded up.
EAS On
Setting EAS On will load the entire incoming EAS message into memory. It
will then cut down the DSK 2 keyer, load the Easytext file (as specified by
the priority of the stored message) and bring the crawl to air.
To change the default appearance of the EAS messages (i.e. scroll speed, font
size, colour, etc.) the following Imagestore files should be modified within
the Easytext application:
• EASHighHD.oxa Priority 1 (high)
• EASMidHD.oxa Priority 2 (medium)
• EASLowHD.oxa Priority 3 (low)
(The render time of the text will depend on the length of the string.
Maximum length = 1990 characters)
EAS Off
Setting EAS Off will remove the EAS crawl from air and restore the original
DSK 2 keyer image, only after the entire message has been displayed.
