MIL-HDBK-1300A
5. DETAILED DESCRIPTION
5.1 Overview. The image and communications processing components of the NITFS are described in this section. It includes data structure, graphics, and image compression algorithms. The communications components include communications protocols and error correction methods.
5.2 Format.
5.2.1 Data structure.
5.2.1.1 Preface. NITF is the designated format for transmission of digital imagery and image-related products by the DOD and other members of the Intelligence Community. The NITF provides a common basis for the digital interchange of images and associated data among a variety of existing and future systems.
5.2.1.2 Goal. The goal of the NITF is to provide a common format for transferring imagery and image-associated data among a wide range of existing and future systems, while minimizing overhead processing and storage requirements. To serve adequately a varied group of users communicating multiple types of data using differing hardware and software systems, the standard format must possess the following characteristics:
a. Completeness - allows transmission of imagery and image related data.
b. Simplicity - requires minimal preprocessing and postprocessing of transmitted data.
c. Minimal overhead - minimizes overhead, particularly for users transmitting only a small amount of data and for bandwidth-limited users.
d. Universality - provides universal features and functions without requiring commonality of hardware or non-NITF software.
5.2.1.3 Objectives. The objectives of the NITF are as follows:
a. To provide a way that diverse systems can share imagery and associated data. b. To allow a system with one transmission to send information to users of
varying needs or capabilities, so that each user selects from the transmission only those data items that correspond to the needs and capabilities of the recipient.
c. To minimize the cost and schedule impacts of hardware and software implementation required to achieve such capability.
5.2.1.4 Concept. In the NITF concept, data interchange among systems is enabled by a cross- translation process. Each system will have processors to translate between the system's internal
