Configuring Metadata Capture


Metadata processing is a licensed feature which may be installed at the factory or via a field upgrade by installing a license file.

From the Metadata pages, you can configure the Makito X to capture either KLV (Key Length Value) or CoT (Cursor on Target) metadata and then incorporate data information within the metadata elementary stream of the standard MPEG Transport Stream.

You can set up multiple metadata inputs to include in Transport Streams. The Makito X supports up to three metadata input types:

  • Serial port (Makito X SDI only): The Makito X SDI extracts either KLV or CoT metadata packets from the COM1 serial port. See Configuring Serial Metadata Sources.
  • SDI (Makito X SDI only): The Makito X SDI extracts KLV metadata packets from the HD-SDI interface as per MISB RP 0605.2. See Configuring HD-SDI Metadata Sources.
  • Network: The Makito X captures metadata from a user definable network port (up to eight UDP inputs). The encoder can receive either (a) KLV payload encapsulated in UDP or (b) CoT inside UDP that is converted to KLV and then streamed. See Configuring Network Metadata Sources.

The Makito X auto-detects the hardware setup of the encoder. If the serial port or SDI video is connected, the serial or SDI metadata source is created automatically at startup by the system. For Serial input, the COM Port Mode must also be set to Metadata (see "Mode" in COM Port Settings). UDP sources must be manually created by the user. The Makito X supports insertion of multiple metadata sources into the same KLV Elementary Stream.

The Makito X supports both synchronous and asynchronous KLV metadata stream signaling and AU (Access Unit) transport support. When configuring a stream, you can select the encapsulation type to use for the associated KLV metadata source. For technical specifications, see Asynchronous KLV Metadata Support.

CoT/UDP and CoT/Serial metadata sources can also be retransmitted to other IP destinations for follow-up analysis by third party systems. For more information, see CoT Relaying.

You can define a small set of static KLV objects (i.e., mission IDs and security classification) for KLV and CoT metadata sources. For more information, see Mission ID/Security Data Set Insertion.

Metadata List View

To open the Metadata List View:

  1. On the Streaming page, click General Settings on the navigation bar and Metadata on the sidebar. 
    The Metadata List View opens, displaying the list of defined Metadata sources for the encoder. The following example shows Serial, SDI and Network metadata sources.

    The Metadata List View displays the Status LED, source Name, Type, Format, and Parameters for each source. It also provides an option for you to either start or stop each source.
    • To view or modify source details, click a link in the table to open the Metadata Detail View.
    • To add a Network or HD-SDI source, click the 
      Add button.
    • To change the status for a source, click the drop-down list under Action and select either Start or Stop (as applicable). You can also delete a Network source.
  2. To apply your changes, click Apply.
