New Initiatives for Imagery Transmission Over a Tactical Data Link. a Case Study: JPEG2000 Compressed Images Transmitted in a Link-16 Network. Method and Results
This paper presents the results of an initiative to transmit imagery content through a Link-16 tactical network using a multi-resolution approach based on wavelets to compress images. Firstly, the authors identify the operational requirements. Secondly, they justify why JPEG2000 is their choice for coding still images. Thirdly, they propose a method to map the JPEG2000 code-stream into Link-16 free-text messages. They propose to send the most important part of the JPEG2000 compressed image in a more error resistant Link-16 packed structure and the remaining of the image in less robust data structures but at higher data rates. Finally, they present their results based on software simulations and laboratory tests with real Link-16 terminals including a comparative analysis with Link-16 enhance throughput.
