Section 10 — Channel Branding Configuration
Entering a Horizontal value of 61.26% and a Vertical value of 85.47% will
result in a default position of the upper left corner is 1176, 923 on a target
Maestro channel configured for 1080I.
Percent values for default positioning are used instead of absolute Pixel
and Scan Line values in the Content Definition table because it this table is
independent of the video standard for which the target Maestro channel is
configured. This independence allows information in the Content Defini-
tion table to be used on multiple channels with various video standards.
The upper left corner of the content bounding box can be positioned any-
where within the raster. For example, content that is positioned at
100%,100% (in the bottom right corner) will be off the screen and will not
be visible. The implication of this variation is that content can be moved off
the bottom or the right of the screen but cannot be moved off the top or left
of the screen.
