AAP Internal Metadata
Dolby Digital
When using Dolby Digital encoding, if you select
AAP Internal
metadata generator as the
Metadata Source
one program is available (the
Metadata Index
parameter is disabled).
However, all other metadata sources have up to eight programs available. Use the
Metadata Index
parameter to select the program you wish to encode.
Dolby E
Using Dolby E encoding, up to eight metadata programs may be encoded, depending on
the setting of the
Program Configuration
parameter. For example, if you set
Program
Configuration
to
5.1+2
, two sets of metadata are encoded (one for
5.1
, one for
2
). If
Program Configuration
is set to
8x1
, eight sets of metadata are encoded. To configure
the metadata settings for each program, navigate to the
AAP Internal Metadata
menu
and select the desired program from the
Program Select
parameter. Then configure the
metadata settings as required.
Note:
Dolby E is always in sync with the frame rate of the video. To ensure downstream
decoders work correctly, you must make the correct settings in
Dolby E Sync Select
(default is
Processing Ch 1 Output)
.
Dolby Audio Metadata
When you apply external metadata to the X50, the metadata properties persist even after
you remove the external metadata from the module. Performing a
Factory Default
of the
user settings
does not
clear the metadata properties that were received when external
metadata was present. After you remove the external metadata, you must restart the
module to clear the metadata properties.
For general information about the use of audio metadata in professional video applications,
visit the Dolby Web site at
Dual-Input Dolby Decoder
The dual-input Dolby Decoder feature is available for all of the Dolby Decoder modes. Once
an AAP is configured in one of the Dolby decoder modes, the Dual-Input function can be
activated in the menu (
AAP-X Input Routing > AAP-X Dolby Source Select
) by selecting
the appropriate source into
AAP-X Secondary Dolby Source Select
(the default is
None
).
This feature is useful for cases where a PCM program is available on one audio pair and a
Dolby program is available on a different audio pair. In such cases, the PCM pair needs to be
routed into the primary input, and the Dolby pair into the secondary input. The decoder will
automatically switch to PCM bypass (from the primary input) whenever the Dolby stream
stops.
Ensure that you check the read-only
Bitstream Format
parameter in the Dolby Decoder
menu (within the AAP block) to determine whether PCM input (
Non-Dolby
) or one of the
Dolby inputs is being processed.
illustrates the behavior of the decoder. See the additional notes at the bottom of
the table.
