MISB 0903.3 Converter library

Introduction

MISB 0903 Converter library aims to facilitate development of the applications for delivering and processing Video Moving Target Indicator (VMTI) metadata and related Track metadata in accordance with SMPTE ST 336:2007 standard. The data created using MISB 0903 Converter library may either complement the MISB 0601.X data set or be sent / received as a 'stand alone' stream, independent of any motion imagery.

Use Cases:

• VMTI packets encoding.
• VMTI data decoding.

Pixel information for video overlay

VMTI video overlay

Geo information for map overlay

VMTI targets on a map

What's in the SDK:

• STD0903 Encoder (C++).
• STD0903 Decoder (C++).
• STD0903 Encoder (.Net).
• STD0903 Decoder (.Net).
• Helper functions and demo source code.
• 32 / 64 bit libraries
  
  The intent is to provide a software tools for VMTI and Track metadata processing for the purpose of populating Situational Awareness products and Common Operating Pictures, for generating VMTI and Track overlays on video players, and for providing input to tracking and data fusion systems (e.g., STANAG 4676 ISR Tracking compliant systems).

The base structure of the VMTI data system is the VMTI Local Data Set. This LDS contains the core information applicable to all reported phenomena within a video frame. The VMTI LDS makes use of a subordinate VTargetSeries that, in itself, contains one or more VTarget Packs which, in turn, may make use of five subordinate Local Data Sets arranged as shown in Figure 1.

Figure 1. VMTI Packet.

VMTI Packet is a complex data system where information exists not just in the data elements, but also in the relationships and structures within which those elements exist. Target unique information is contained within the VTargetSeries.

Figure 2. Sample VMTI Local Data Set Packet (MISB STD 0903.3 spec).

Here is a sample VMTI Packet data with a Local Data Set and 2 targets .

Internal SDK classes follow VMTI packet hierarchy:

• ISTD0903Converter - main SDK interface.
• VMTI_Packet - VMTI packet Local Data representation.
• VTargetPack - TargetPack representation.

Main SDK Interfaces.

• C++ ISTD0903Converter
• .Net STD0903ConvWr::ISTD0903ConverterWr

.Net library is a C++/Cli wrapper for the C++ library. It provides the same basic encoding / decoding functionality with some additional helper functions (for example,like transcoding to JSON)

Getting started with STD0903 Converter.

STD0903 Converter SDK comes with the sample source code to help you get started. Here are some examples of SDK usage for basic tasks.

Sample 1 - Encoding (C++).

Using STD0903 Converter to create a VMTI packet and get a data buffer (C++).

Sample 2 - Decoding (C++).

Using STD0903 Converter to decode a data buffer that contains a VMTI packet (C++).

Sample 3 - Accessing Data (C++).

Iterating the VMTI packet and printing the results (C++).

Sample 4 - Decoding (C#).
