The ISO/IEC 23091 series defines various systems code points and fields that establish properties of a multimedia stream that are independent of the compression encoding and bit rate. These properties could describe the appropriate interpretation of decoded multimedia data or could, similarly, describe the characteristics of such signals before the signal is compressed by an encoder that is suitable for compressing such an input signal.
NOTE This document specifies a URN format applicable to code points from any part of the ISO/IEC 23091 series, and could be revised in future to contain code points specific to multimedia systems (in contrast to video and audio).st edition 2018-04 Information technology — Coding- independent code points — Part 1: Systems Technologies de l'information — Points de code indépendants du codage — Partie 1: Systèmes Reference number ISO/IEC 23091-1:2018(E) ？ ISO/IEC 2018 ISO/IEC 23091-1:2018(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO/IEC 2018 All rights reserved.
