IEC 61162-450:2018 specifies interface requirements and methods of test for high speed communication between shipboard navigation and radiocommunication equipment as well as between such systems and other ship systems that need to communicate with navigation and radio-communication equipment. This document is based on the application of an appropriate suite of existing international standards to…

IEC TR 62351-90-1:2018(E) addresses the handling of access control of users and automated agents to data objects in power systems by means of role-based access control (RBAC) as defined in IEC TS 62351-8. The main focus of this document lies in developing a standardized method for defining and engineering custom roles, their role-to-right mappings and the corresponding infrastructure support…

This part of ISO/TR 19566 describes common elements of a system layer for JPEG standards, referred to as JPEG Systems. This part of ISO/TR 19566 describes the common architecture of file formats and codestream formats used in JPEG standards. It is intended that all future Systems components support codestreams and file formats following these guidelines.

This document collects important information with the goal of elaborating a system layer for JPEG standards, referred to as JPEG systems. This document summarizes the principles of incremental codestream and file transport that are intended to form the future building blocks JPEG systems. Industrial implementations, future codecs and systems components are encouraged to follow these guidelines.

This part of ISO/IEC 23001 specifies common encryption formats for use in any file format based on ISO/IEC 14496-12. File, track, and track fragment metadata is specified to enable multiple digital rights and key management systems (DRMs) to access the same common encrypted file or stream. This part of ISO/IEC 23001 does not define a DRM system. The AES-128 symmetric block cipher is…

This part of ISO/IEC 23001 specifies a common media encryption format for use in MPEG-2 transport streams. This encryption format is intended to be used in an interoperable way with media encrypted using the format described by ISO/IEC 23001-7. This part of ISO/IEC 23001 allows conversion between encrypted MPEG-2 transport streams and encrypted ISO base media file format files without re-…

This Recommendation International Standard defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone grey-scale, palletized colour, or continuous-tone colour digital still images. This Recommendation International Standard: - specifies decoding processes for converting compressed image data to reconstructed image data; - specifies a…

ISO/IEC 12034-1:2017 is Part 1 of a series of documents that specify a general-purpose format for the storage and/or communication of information in bulk form. The format is named the Archive eXchange Format (AXF). The format described is intended both for interchange between systems and to serve as a native format within systems. ISO/IEC 12034-1:2017 identifies two major categories of data…
