LibMISB

libMISB – Metadata Encoding and Decoding for MISB KLV Standards

RidgeRun’s libMISB is a lightweight, production-ready C library for encoding and decoding metadata using the MISB KLV (Key-Length-Value) protocol, with initial support for ST 0601 (UAS Datalink Metadata) and extendable to other standards upon request. Designed for defense, surveillance, and aerospace systems, libMISB simplifies the handling of KLV packets in real-time video pipelines, enabling seamless metadata management for STANAG 4609 and other related ecosystems.

Built with embedded integration in mind, libMISB removes the complexity of parsing and generating compliant metadata—so you can focus on your application logic, not the standard's internals.

Key Features:

• MISB ST 0601 Support (Out of the Box)
  Fully supports the widely-used ST 0601 metadata format for UAVs and ISR systems.

• KLV Packet Encoding & Decoding
  Encode metadata from structured input or decode binary KLV packets into human-readable, structured data.

• Auto-Detection of Standards
  No need to hard-code MISB standards—libMISB interprets the format from the input metadata file or encoded packet.

• Extendable Architecture
  Additional standards like ST 0806, ST 2101, or full STANAG 4609 support can be added upon request.

• Simple Integration into C and GStreamer Applications
  Use the standalone library or plug into GStreamer pipelines with RidgeRun’s application examples.

Example Use Case:

An unmanned aerial system (UAS) streaming surveillance video embeds ST 0601-compliant KLV metadata (GPS coordinates, heading, platform speed) using libMISB. On the ground, a command center decodes the same stream with libMISB to overlay metadata on video playback and trigger geofencing alerts—all without writing custom metadata parsing code.
