The Network-Based Media Processing framework defines the interfaces including both data formats and

APIs among the entities connected through the digital networks for media processing. Users can access

and configure their operations remotely for efficient intelligent processing. It describes and manages

workflows to be applied to the media data. This process includes uploading of media data to the network,

instantiation of the media processing tasks, and configuration of the tasks. The framework enables

dynamic creation of media processing pipelines, access of processed media data and metadata in realtime

or in a deferred way. The media and metadata formats used between the Media Source, Workflow

Manager and Media Processing Entities in a media processing pipeline are also within the scope.

The ISO/IEC 21122 standard, also known under the term JPEG XS, specifies a low-latency, lightweight image compression system offering compression tools for high-speed, ultra-low online compression of images and image sequences.

This document contains the reference software of JPEG XS. Its purpose is to act as a guideline for implementations and as a reference for conformance testing. It has been successfully compiled and tested on Linux and WindowsTM operating systems at the time of writing.
