MIL-STD-188-197A establishes the requirements to be met by systems complying with NITFS when image data are compressed using the Adaptive Recursive Interpolated Differential Pulse Code Modulation (ARIDPCM) compression algorithm.  It provides technical detail of the NITFS compression algorithm designated by the code C2 in the image compression field of the image subheader, ARIDPCM, for both 8- and 11-bit gray scale imagery and the required default ARIDPCM quantization tables for use in NITFS compliant imagery dissemination systems.
