Configuring Metadata Capture
NOTE
Metadata Capture is an optional feature and must be installed at the factory.
The Makito provides a
M

page and separate
M

pages
for up to eight metadata inputs, consisting of either one SDI input, one Serial input, or up
to eight UDP inputs.
From the
M
ETADATA
S
ETTINGS
page, you can configure the Makito to capture either KLV
(Key Length Value) or CoT (Cursor on Target) metadata and then incorporate data infor-
mation within the metadata elementary stream of the standard MPEG Transport Stream.
The Makito supports three metadata input types: either from the COM1 serial port, the
HD-SDI interface (Makito-SDI only), or a user definable UDP port. You can set up
multiple metadata inputs to include in Transport Streams.
The available input types depend on the hardware setup of the encoder; i.e., whether the
serial port or SDI video have been connected; UDP is always available.
Only one metadata stream may be included in the Transport Stream at a time, so you must
select the metadata source:
• Serial port: The Makito extracts either KLV or CoT metadata packets from the serial
port. From the M
ETADATA
page, you must specify the Data Format , and for CoT
metadata, the Max AirCraft-SPI Delta . The CoT metadata capture option requires
Serial port input.
• SDI: (Makito-SDI only) The Makito extracts KLV metadata packets from the HD-SDI
interface as per MISB RP 0605.2. Only progressive scan formats are supported (i.e.,
1280x720p and 1920x1080p). The Makito can capture only 4096 bytes of KLV
metadata per video frame.
• UDP: The Makito encodes and converts UDP packets to KLV, and inserts them into
the Transport Stream.You must specify local UDP Port on the Makito that is receiving
the packets. The IP Address is only required for reception of multicast metadata, or if
you only want to accept KLV messages coming from a specific sender.
When configuring the metadata input, you do not need to select the Input type. The Makito
will auto-detect the hardware setup of the encoder; i.e., whether the serial port or SDI video
is connected; UDP is always available.
