Key Length Value (KLV) Metadata : Inserting KLV Metadata : Exploitation Support Data (ESD) to Local Data Set (LDS)
  
Exploitation Support Data (ESD) to Local Data Set (LDS)
Exploitation Support Data (ESD) to Local Data Set (LDS) uses line 21 (typically used for closed captions) of the video format as an in-band transport mechanism. The embedded text is limited to 120 characters per frame. Control and management of the LDS insertion parameters are available using the VBAdmin Web interface, the Command Line Interface, or SNMP. ESD is converted to LDS per MISB standard 0601 and MISB EG 0104.5. The LDS metadata packets PTS (timestamp) source is the system capture time of the first byte of ESD data.
*To configure ESD to LDS:
1. Navigate to Encoder Configuration > Video.
2. Set KLV to ESD to LDS.
3. Configure the data to be streamed in the ESD Field as Field One, Field Two (default), or Field One and Two.
4. Navigate to Encoder Configuration > Streams.
a. Set Transport Type to MPEG2TS.
b. Check Enable KLV.
c. Configure other advanced settings as necessary.
5. When done the data present in the stream (defined by the ESD Field) will be encoded and delivered with the stream.
6. To view ESD throughput, go to Monitor > Encoder Status > Monitor Video Input Fields.
