Asynchronous KLV Metadata Support
The Makito
X supports Asynchronous Key-Length-Value (KLV) metadata stream
signaling and AU (Access Unit) transport support (as per MISB 0604.2).
The Makito
X allows users to select the encapsulation type to use for each metadata source.
This provides increased flexibility with regard to systems inter-working with the Makito
X.
The available encapsulation types are as follows:
•
Synchronous: The Sync format is implemented in compliance with MISB 0604.2
Section 7.2.1 and ISO 13818-1 Section 2.12. Both content type signaling and data
transport use this format.
•
Asynchronous: The Async format is implemented in compliance with MISB 0604.2
Section 7.2.2. See also SMPTE RP 217. Both content type signaling and data transport
use the Async format.
•
Asynchronous With Sync AU: The AsyncWithSyncAu format uses the Async PMT
and PES header signaling format as per MISB 0604.2 Section 7.2.2 and SMPTE RP
217. However, the PES payload / metadata AU is formatted in the same manner as the
Sync option in compliance with ISO 13818-1 Section 2.12.
The default value for the metadata encapsulation is Synchronous.
The encapsulation type may be selected from the Web Interface (Output Streams Detail
View), the CLI (
stream
command), or via SNMP.
