frame of the animation element until it is removed from the program
output.
An Animation sequence is created as a sequence of still images and may be
associated with an Audio element for combined playout. The Audio
element will be played from the clip cache.
The term "snipe" is sometimes used to describe a lower-third animation
sequence or motion video playback for program promotion or as a paid
commercial tag. Although audio may be associated with an animation
sequence, a "snipe" is usually video only.
The Maestro Channel Branding will accept and convert animation
sequences or motion video in the following data formats:
• Mkvmerge GUI Saved Muxing Settings (.MMG)
• Graphics Interchange Format (.GIF)
Text Crawls
Text Crawls are a special case of an animation element in which the text
content of the animation is created outside of Channel Branding and is then
reformatted for Channel Branding playout. The source of the text data may
be external or internal to the Maestro system environment. The text data
must be processed and inserted into a predefined animation sequence tem-
plate that specifies the display parameters such as font, size, color, border/
edge effect, background elements, and speed of crawl or text reveal.
Text Crawls are one or more text lines, with associated formatting, that
move across the display screen in a horizontal (right to left) direction and
are shown in a single line. The defined speed indicates how fast the text
moves across the screen. The speed is defined in the Crawl Rate (pixel/frame)
field on the Content tab.
The Text Crawls feature includes the ability to insert still images and an ani-
mation into a Text Crawl.
Emergency Messaging Support
In the United States, broadcasters are required to support and display test
and alert messages that are generated by the Emergency Alert System
(EAS). Several message types and display formats are specified. In addi-
tion, certain message types contain a voice announcement that must be
repeated and/or transcribed before the test or alert is displayed on the
broadcast channel. (See the FCC document at: http://hraunfoss.fcc.gov/
edocs_public/attachmatch/DOC-278628A5.pdf)
The EAS test or alert is received over-the-air and monitored by an
approved EAS Decoder. The EAS Decoder recognizes the EAS message
