Cascading Logo Replacement Rules
the Substitution field, an asset called iTX-Logo_HD would be substituted for a file called
iTX-Logo_SD before playing out on the simulcast channel.
Note:
• If Logo or CG are selected for substitution, live logos and live captions will
also be subject to the same replacement rules.
• Both the original and the substitution assets must be available on the
media store in order for the substitutions to take place.
• If you are operating a simulcast backup channel, you must apply the same
substitution rules on the simulcast channel as its simulcast channel.
Cascading Logo Replacement Rules
On playout, if a scheduled logo is defined in the Logo Setup plugin it will be substituted for
its replacement before going to air.
If you are running a Simulcast channel and the replacement logo then meets the criteria
defined in the Simulcast Replacement Rules, a further replacement will be performed.
This provides two levels of control for logo replacement, as illustrated by Figure 6-1.
