T*AP
setup GUI – DOLBY PROCESSING
®
The Dolby
metadata system is too complex to describe it in a product manual like this.
We recommend to those who are not familiar with it, to study the many publications from Dolby® Inc.
which you will probably find here (we can't guarantee that the link is active forever) :

But so much for the beginning: The system is designed to squeeze multiple audio signals into standard
2 channel transmission / recording lines. The codecs used for this purpose are intellectual property of
Dolby® Labs. Inc. Additional metadata has been implemented to control the customer experience at home
when listening through TV set top boxes, DVD players, gaming machines, mobile devices.
Dolby distinguishes between consumer and professional metadata. While consumer meta data will travel to
the consumer equipment, the professional metadata is used for the setup of encoders.
The appearance of the following pages depends on the number and type of Dolby decoders / encoders
installed. These modules are an option which may be ordered with the T*AP or later on for field installation.
setup GUI – DOLBY PROCESSING – Metadata – Routing
The center of the T*AP Dolby processing is the built in Metadata processor. It can be the point of origin of
metadata but it may also modify existing metadata from an available source :
At the bottom right hand side you see the metadata output router. Here you may decide about the Source
that feeds the respective Output.
Source
Important note! The metadata processor generates a full set of SMPTE RDD 6 compliant metadata.
Since the T*AP is designed to handle two (5.1+2) or 4 (4x2) programs all related parameters will be
generated by the processor.
The function blocks Monitor, Follow Input and Delay are not implemented for T*P firmware release 3.1.x
[OFF / D SUB IN / SDI1 VANC / DECODER /
METADATA PROCESSOR]

The metadata system of the T*AP has three
paths. An independent monitor will allow for
the evaluation of an independent metadata
set, selected by its Source drop down box.
The Metadata Processor in the middle may
take it from an available Source, may
manipulate it in the Follow Input section and
present it to the router for further distribution
at the Output.
The Metadata Source Status
The soft LED turns red If no metadata is
present or the metadata is corrupted.
It turns green and the word OK will be
displayed if a RDD 6 compliant metadata
stream is detected.
It turns yellow and the word CONSUMER
will be displayed to indicate that only a
metadata subset is provided if an AC3 or
similar (D-D+) signal is decoded.
