Metadata
Dolby metadata contains information about the audio bit-stream including
what configuration of “programs” is being carried; for example 5.1 + 2. As
such, Dolby metadata may be used to drive an Up-Mix processor.
Metadata may be carried within Dolby signal on AES or SDI or separately on
a RS485 serial connection.
Metadata handling within the Imagestore 750 includes:
•
AB switching of metadata synchronously with audio AB-mix
•
RS485 serial metadata connections, flexible inputs and outputs
•
User-defined metadata presets
•
Internal metadata generation from selectable user-defined presets
•
Changing internally-generated metadata via automation
•
Flexible metadata internal routing, including simple passing
This is explained in the Dolby section on page 357.
Metadata Monitoring/Processing
The Imagestore 750 may route metadata from any one of its internal metadata
sources. This includes using user-defined metadata presets to set up the
metadata audio channel mode, parameters of which can then be modified via
automation.
Note: There is no support for dynamic processing of metadata
parameters contained within an external Dolby bit-stream.
Metadata User-Defined Presets
There are four user-defined metadata presets available in the Imagestore 750.
The metadata presets form a complete list of all metadata parameters.
There are four internal metadata sources, called “banks” or “processors”.
User-defined preset parameters can be loaded into these metadata “banks”.
