Dolby E metadata
configuration
(Option DBE only)
NOTE.
Use caution when changing the Dolby E metadata values. Changing the
metadata does not change the encoded audio. Changing the metadata values
from default values may cause the signal to not decode correctly.
When you configure the Dolby E metadata, depending on your selections, other
metadata values may change or be limited as follows:
Program setting.
The Program setting is the primary metadata control. When you
select a program type, the metadata is set according to that program type.
For example, if you set the Dolby E program to 5.1, the Dolby E bit depth setting
remains as it is and the user interface for the bit depth control shows both 16-bits
and 20-bits as being available.
Frame rate setting.
If you change the Dolby E frame rate setting, it does not affect
the actual audio data being streamed out by the generator, and it does not change
the rate at which this data is being streamed or the video frame rate itself.
