35.040.40 - Coding of audio, video, multimedia and hypermedia information

The network-based media processing (NBMP) framework defines the interfaces including both data formats and application programming interfaces (APIs) among the entities connected through digital networks for media processing. Users can access and configure their operations remotely for efficient, intelligent processing. This document 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 ...view more

This document specifies advanced video coding for coding of audio-visual objects

This document specifies the ISO base media file format, which is a general format forming the basis for a number of other more specific file formats. This format contains the timing, structure, and media information for timed sequences of media data, such as audio-visual presentations.

This document provides guidance for implementing and deploying systems based on ISO/IEC 23008‑1.

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 requirement...view more

This document contains the reference software of the ISO/IEC 21122 series. It acts as a guideline for implementation and as a reference for conformance testing.

This document specifies a file format for interchanging audio data between compliant
equipment. It is primarily intended for audio applications in professional recording, production,
post-production, and archiving.
It is derived from the AES31-2 [2] but is also compatible with variant specifications including
EBU Tech 3285 [3] to [10], ITU-R BR.1352-3-2007 [11] to [14], and the Japan Post Production
Association's BWF-J [15].
This document contains the specification of the broadcast audio e...view more

This document specifies the conformance and reference software implementing the test vectors comprising media presentation descriptions, segments and combinations thereof in ISO/IEC 23009‑1, and the corresponding software modules.

This document specifies the architecture of MPEG-V (media context and control) and its three types of associated use cases: — information adaptation from virtual world to real world; — information adaptation from real world to virtual world; — information exchange between virtual worlds.

This document specifies high efficiency video coding.

This document specifies the conformance and reference software implementing ISO/IEC 23093-3. The information provided is applicable for determining the reference software modules available for ISO/IEC 23093-3, understanding the functionality of the available reference software modules, and utilizing the available reference software modules. Furthermore, this document provides means for conformance testing, i.e. bitstreams ? XML descriptions ? that conform or do not conform to ISO/IEC 23093-3.

This document specifies a unified speech and audio codec which is capable of coding signals having an arbitrary mix of speech and audio content. The codec has a performance comparable to, or better than, the best known coding technology that might be tailored specifically to coding of either speech or general audio content. The codec supports single and multi-channel coding at high bitrates and provides perceptually transparent quality. At the same time, it enables very efficient coding at very ...view more

This document specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim conformance to multiple parts of the ISO/IEC 21122 series. It lists the conformance testing procedures. This document specifies: — Conformance testing procedures for decoders implementing ISO/IEC 21122-1. — Conformance testing procedures for decoders implementing ISO/IEC 21122-3. — Tests to check codestreams for conformance to ISO/IEC 21122-1. As such, it provides means to test whether ...view more

This document contains simulation software for the MPEG-H 3D audio standard as defined in ISO/IEC 23008‑3.

The ISO/IEC 15938 series operates on and generates conformant bitstreams. This document provides a specific implementation that behaves in a conformant manner. NOTE 1 Other implementations that conform to the ISO/IEC 15938 series are possible, which do not necessarily use the algorithms or the programming techniques of the reference software. The software contained in this document is known as eXperimentation Model (XM) and is divided into five categories: a) Binary format for MPEG-7 (BiM). This...view more
