Metadata
Dolby metadata contains information about the audio bit-stream including what configuration
of “programs” is being carried; for example 5.1 + 2. Therefore, you can use Dolby metadata to
drive an up-mix processor.
Metadata can be carried in the Dolby signal on AES, on SDI, or separately on an RS-485 serial
connection.
Metadata handling within the Imagestore 750 includes:
• A/B switching of metadata synchronously with the audio A/B mix.
• RS-485 serial metadata connections.

• Flexible inputs and outputs.
• Custom-defined metadata presets.
• Internal metadata generation from selectable custom-defined presets.
• Changing internally-generated metadata through automation.
• Flexible routing of metadata internally.
These points are explained in Dolby Metadata on page 120.
