Overview of JPEG Systems
JPEG has launched a systematic review and consolidation of its file formats, functionalities and codestream syntax. The goal is to define an overall framework for future and legacy standards called JPEG Systems to ensure interoperability and functionality exchange between these standards.
JPEG Systems intends to specify a system layer structure for JPEG standards to enable generic support for interactivity protocols, High Dynamic Range (HDR) tools, security and privacy, augmented reality and 3D. Ontology technologies are expected to play an important role in this effort. The current activities with respect to HDR extensions and privacy & security are important precursors of larger standardization effort.
As a first result a box based structure was agreed for future extensions. For this reason the HDR extension within the well accepted JPEG-1 standard 10918 will have a box type style within the APP marker segment.
