Metadata Indirect AB-Switched Routing
Next metadata is sourced from one of two RS485 inputs, depending on the
position of the audio AB mixer. The metadata sources are cut at the half-way
point of an audio AB mix.
The metadata is then included within the Dolby E output via the PGM SDI
stream as before.
Note: Metadata that is generated internally by the Imagestore is set up
via “Metadata Mode” within the Configurator tool.
