Features
This section provides a brief overview of the Transparent Module features.
Data Type
The Transparent Module supports both specific and non-specific data types. Audio Metadata is an
example of a specific data type. Audio Metadata has a particular format and must be formatted in
that way to be accepted as a source for insertion. The Transparent Module will also handle
non-specific data. In this mode whatever data you give the module is inserted into the VANC.
Byte Mode
Byte Mode allows non-specific data to be inserted into the VANC. The data will be inserted into a
single packet on a single line and will be inserted as soon as possible. At each insertion
opportunity the TES9 will take the data accumulated from the source and build it into a packet
and insert it. If you try to provide data faster than can be carried in one packet per field then the
TES9 will flow control the data source. The setup software will make most of the other settings
for you. You should set the DID/SDID to values appropriate for the type of data being sent.
Audio Metadata
The Audio Metadata selection is for a source providing a serial audio metadata stream in
accordance with SMPTE. When you select Audio Metadata the setup software will make most of
the other settings for you. Normally, audio metadata is provided by a serial port configured to
115,200,N,8,1.
Caption CDP
The Caption CDP selection is for a source providing data formatted as Caption Distribution
Packets (CDPs). This is the type of data used in CEA 708 captioning for HDTV. The setup
software will make most of the other settings for you. The source must provide CDP packets
correctly timed to the video. That means a CDP must be provided for each field 1 of the video.
Subtitle SDP
The Subtitle SDP is for a source providing data as Subtitle Distribution Packets (SDPs). This is
the type of data used to carry WST subtitling information in an HD signal. The data must be
formatted according to OP47. The setup software will make most of the other settings for you.
High Capacity
Like Byte Mode, High Capacity allows non-specific data to be inserted into the VANC. High
Capacity allows data to be inserted into multiple packets on multiple lines and requires exclusive
use of the lines to do so. The setup software will make most of the other settings for you. If you
send more data to the High Capacity stream than can be carried in the lines selected then the
source will be flow controlled. You should set the DID/SDID to the values appropriate for the
type of data carried.
Custom
In Custom mode you must make all of your own settings. Normally, one of the other modes will
provide the functionality that you require. If not, then Custom mode and a thorough
understanding of the settings will allow you to send many different types of data.
