This recommendation - International Standard provides accompanying reference software for ISO/IEC 23090-9 as an electronic attachment. The use of this reference software is not required for making an implementation of an encoder or decoder in conformance to ISO/IEC 23090-9. Requirements established in ISO/IEC 23090-9 take precedence over the behavior of the reference software.
This document specifies a video coding technology known as essential video coding (EVC), which contains syntax format, semantics and an associated decoding process. The decoding process is designed to guarantee that all EVC decoders conform to a specified combination of capabilities known as the profile, level and toolset. Any decoding process that produces identical cropped decoded output pictures to those produced by the described process is considered to be in conformance with the requirements of this document. This document is designed to cover a wide range of application, including but not limited to digital storage media, television broadcasting and real-time communications.
ISO/IEC TR 15938-8:2002 forms an informative part of ISO/IEC 15938 on extraction and use of metadata descriptions for multimedia content. ISO/IEC TR 15938-8:2002 provides two types of information: informative examples that illustrate the instantiation of description tools in creating descriptions conforming to ISO/IEC 15938; and detailed technical information on extracting descriptions automatically from multimedia content and using them in multimedia applications. ISO/IEC TR 15938-8:2002 is a companion for ISO/IEC 15938-3 (Visual) and ISO/IEC 15938-5 (Multimedia Description Schemes), which provide normative definitions of the description tools. Effort has been made in this Technical Report to preserve the subclause numbering of ISO/IEC 15938-3 and ISO/IEC 15938-5 to allow easy mapping of the information on extraction and use with those technical specifications.
This document specifies extensions to existing scene description formats in order to support MPEG media, in particular immersive media. MPEG media includes but is not limited to media encoded with MPEG codecs, media stored in MPEG containers, MPEG media and application formats as well as media provided through MPEG delivery mechanisms. Extensions include scene description format syntax and semantics and the processing model when using these extensions by a Presentation Engine. It also defines a Media Access Function (MAF) API for communication between the Presentation Engine and the Media Access Function for these extensions. While the extensions defined in this document can be applicable to other scene description formats, they are provided for ISO/IEC 12113.
ISO/IEC 15938-5:2003 specifies a metadata system for describing multimedia content. ISO/IEC 15938-5:2003 specifies the Multimedia Description Schemes (MDS) description tools (Description Schemes, Descriptors, and datatypes) that comprise ISO/IEC 15938-5:2003 by specifying the normative syntax of each description tool using Description Definition Language (DDL) (see ISO/IEC 15938-2) and the normative semantics including semantics of each component of each description tool (attributes and elements). ISO/IEC 15938-5:2003 also provides informative examples that illustrate the instantiation of description tools in creating descriptions conforming to ISO/IEC 15938-5:2003.
ISO/IEC 15938-5:2003 defines the following basic elements: schema tools (the root element, top-level types, description metadata, and packages), basic datatypes (integers, reals, vectors, matrices), linking and media localization tools (spatial and temporal localization), basic description tools (language, text, classification schemes). ISO/IEC 15938-5:2003 defines the following content description tools, which describe the features of the multimedia content and the immutable metadata related to the multimedia content: structure description tools (spatio-temporal segments of multimedia content) and semantic description tools (""real-world"" semantics related to or captured by the multimedia content, including objects, events, concepts, and so forth). ISO/IEC 15938-5:2003 defines additionally the following description tools for content metadata: media description (storage format, encoding), creation and production (title, creator, classification, purpose), and usage (access rights, publication). The content description and metadata tools are related in the sense that the content description tools use the content metadata tools. For example, a description of creation and production or media information can be attached to an individual video or video segment in order to describe the structure and creation and production of the multimedia content. ISO/IEC 15938-5:2003 also defines description tools for navigation and access (browsing, summarization), content organization (collections and models), and user interaction (user preferences pertaining to consumption of multimedia and usage history). Finally, ISO/IEC 15938-5:2003 defines classification schemes, which organize terms that are used by the description tools.
ISO/IEC 14496-27:2009 specifies how tests can be designed to verify whether compressed data (i.e. bitstreams) and decoders meet the requirements for the synthetic 3D graphics tools specified in ISO/IEC 14496‑11:2005, ISO/IEC 14496‑16:2006, ISO/IEC 14496‑21:2006, and ISO/IEC 14496‑25:2009. ISO/IEC 14496-27:2009 does not specifically address encoders. As far as synthetic 3D graphics are concerned, an encoder can be said to be an ISO/IEC 14496 encoder if it generates compressed data compliant with the syntactic and semantic bitstream payload requirements specified in ISO/IEC 14496‑11, ISO/IEC 14496‑16, ISO/IEC 14496‑21, and ISO/IEC 14496‑25. Characteristics of coded bitstreams and decoders are defined for ISO/IEC 14496‑11, ISO/IEC 14496‑16, ISO/IEC 14496‑21, and ISO/IEC 14496‑25. The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream. Examples are the applied values or range of the bitrate. Decoder characteristics define the properties and capabilities of the applied decoding process. An example of a property is the applied arithmetic accuracy. The capabilities of a decoder specify which coded bitstreams the decoder can decode and reconstruct, by defining the subset of the standard that may be exploited in decodable bitstreams. A bitstream can be decoded by a decoder if the characteristics of the coded bitstream are within the subset of the normative references. ISO/IEC 14496-27:2009 describes procedures for testing conformance of compressed data and decoders to the requirements defined in ISO/IEC 14496‑11, ISO/IEC 14496‑16, ISO/IEC 14496‑21, and ISO/IEC 14496‑25; given the set of characteristics claimed, the requirements that shall be met are fully determined by these parts. ISO/IEC 14496-27:2009 summarizes the requirements, cross references them to characteristics, and defines how conformance with them can be tested. Guidelines are given on constructing tests to verify decoder conformance.
This document investigates barriers and proposes measures to improve interoperability between geospatial and BIM domains, namely, to align GIS standards developed by ISO/TC 211 and BIM standards developed by ISO/TC 59/SC 13. Where relevant this document takes into account work and documents from other organizations and committees, such as buildingSMART, International (bSI), Open Geospatial Consortium (OGC) and Comité Européen de Normalisation (CEN). The focus is to identify future topics for standardization and possible revision needs of existing standards. This document investigates conceptual and technological barriers between GIS and BIM domains at the data, service and process levels, as defined by ISO 11354 (all parts).
Advice is given for cloud computing ecosystem participants (cloud vendors, service providers, and users) of standards-based choices in areas such as application interfaces, portability interfaces, management interfaces, interoperability interfaces, file formats, and operation conventions. These choices are grouped into multiple logical profiles, which are organized to address different cloud roles.
This document specifies the key requirements of a quality open source license compliance program in order to provide a benchmark that builds trust between organizations exchanging software solutions comprised of open source software.
The present document provides reference test material and test results for improved usability of technologies in 3GPP TS 26.118: Virtual Reality (VR) profiles for streaming applications. The specification 3GPP TS 26.118 includes several VR media profiles for video and a single media profile for audio with different configuration options. The specification focuses primarily on interoperability requirements for VR360 applications, but does not address performance characterization of the solutions. In order for content providers and the rest of the ecosystem to be able to select and configure the technologies defined in 3GPP TS 26.118 and to generate content for streaming applications, collecting such information would be most valuable.
This document specifies how to extend the ISO 32000-2 specification by adding the ISO 10303-242 (STEP AP 242) format as a valid format for 3D assets contained in a RichMedia annotation. It is intended for:
- developers of software that creates PDF files (PDF writers);
- software that reads existing PDF files and usually interprets their contents for display (PDF readers);
- software that reads and displays PDF content and interacts with the computer users to possibly modify and save the PDF file (PDF processors);
- PDF products that read and/or write PDF files for a variety of other purposes (PDF processors).
