Generating and Adjusting Metadata
4.3.1 Choosing the Source of Metadata
Normally you will use an entire metadata stream from one source, but that is not required.
You control this source choice at three levels:
1.
You choose a program configuration. This defaults all parameters for all programs in
the stream to the source you chose: internal, external 1, or external 2.
An example of this configuration is a QC environment, where the operator uses the
entire metadata stream to monitor the overall audio quality.
2. You choose a source for a particular program. This automatically sets the default
source for all parameters in the program but does not affect any of the other programs
in the stream.
3. You can choose an external source for an individual parameter which affects only that
selected parameter.
Typically you would do this to correct a known error.
DolbyRemote 570 makes selecting the metadata source simple. Choosing an external
program configuration or program changes parameter settings automatically. Individual
parameters can still be changed without affecting other parameters.
Metadata source choices stay set until:
•
You manually change a source choice.
•
You receive a different program configuration.
4.3.2 Using Generated Metadata
When the source is internal
,
the default values the DP570 applies are determined by the
