MAESTRO_CONTENT_FILENAME_ASSOCIATION
MAESTRO_CONTENT_FILENAME_ASSOCIATION
(Associate a Content File with an Automation Input Set source)
Hex definition Mnemonic
0x80 MAESTRO_CONTENT_FILENAME_ASSOCIATION
Command format:
MAESTRO_CONTENT_FILENAME_ASSOCIATION
Command notes:
1. This command associates a content filename with an entry in the configured Content Definition table for later assign-
ment and use via the Input Set table. This is done through various levels of indirection as the field references an
entry in the Automation Input table which references an entry in the Input Set table which may reference an entry in the
Content Definition table. If the specified Automation Input does not ultimately reference a Content Definition
table entry, the command will have no effect. This command does not reserve any Maestro system resources. Only upon
assignment of a source defined in the Input Set via the Automation Input set will Maestro system resources be reserved.
Therefore, association of content does not guarantee availability of system resources. Additionally, content associated
with a source (Automation Input) is loaded at the time of assignment to a Keyer or Audio Mixer. Therefore, an already
assigned source for which the content filename association has changed must be unassigned and reassigned to reload the
new content.
2. Filename associations are stored in Non-volatile RAM. If the user clears the non-volatile RAM on the Maestro Frame
Processor, all existing filename associations will also be cleared and all sources will revert to the default pathname speci-
fied in the configuration. Therefore, it will be necessary to reestablish filename associations after clearing of non-volatile
RAM.
3. It needs to be noted that content is loaded at the time of Keyer and Audio Mixer source assignment. This has the fol-
lowing implications:
a. Content filename association needs to occur prior to source assignment.
b. If the content filename of an Automation Input changes after it has been assigned to a Keyer or Audio Mixer,
that Automation Input must be unassigned and reassigned to get the newly associated content file.
