4.11.1.2. Dolby-E Encode Module Config
Module: Use the drop-down menu to apply configuration settings to Module 1 or Module 2.
State: Set the state of each Dolby-E encoding module to either Present (on) or Absent (off).
Input Bus: Configure the audio bus (PGM, PST, CLN or AUX) from where the audio source for the
Dolby-E Encoder module will be routed.
Input Encoded Channel: Configure the audio channels that will be Dolby-E encoded. This can also
be done using the “Visualize” settings which allows the user to see all of the
current DE encoder input routes together.
Destination Bus: Configure the audio buses (PGM, PST, CLN and AUX) and channel pairs to
which the encoded Dolby-E will be embedded.
Metadata Source: Configure if the Dolby-E encoder will be using its own internal metadata or if the
encoder will be using metadata routed from the PGM/PST Dolby-E decoder
modules. If Internal is selected then more options become available to the user.
NOTE: If the 3025AP has been configured to accept configuration via MADI IN then
the Metadata Source and Video Standard will be set on the 3025AP automatically (via
MADI) when the configuration file is uploaded to the 3025EMC channel.
Frame Rate: This is fixed and is dependent on the video standard that the EMC is configured to use.
Encoder Config Stream Type: Available only when using Internal metadata. There are 7 different
internal metadata configurations that can be configured here.
Reversion Mode: If the 3025AP board has been configured to accept configuration
over MADI then the Reversion Mode of the 3025AP can be
configured here to be either:
Last Used: If valid metadata is lost at the input of the Dolby-E Encoder then
the last good frame of metadata will be used by the Encoder.
Internal: If valid metadata is lost at the input of the Dolby-E Encoder then
the Encoder will revert to a pre-determined internal program
configuration mode.
4.11.1.3 Dolby Presence Options
Detect Dolby Presence at: Use the drop-down menu to configure the decoder module that
you want to configure. Normally Decoder 1 will be in the PGM
path and Decoder 2 will be in the PST path.
Disable encoder if no Dolby present at decoder: When this option is used the encoded Dolby-E can
be removed from the PGM path automatically if Dolby-E is lost at
the PGM input.
