WG11 (MPEG) fosters Cloud-based Media Processing across Multiple Platforms

Brussels, Belgium – The 129th WG 11 (MPEG) meeting was held in Brussels, Belgium, 12-17 January 2020

Coded representation of immersive media – WG11 promotes Network-Based Media Processing (NBMP) to the final stage

At its 129th meeting, WG11 (MPEG) promoted ISO/IEC 23090-8, Network-Based Media Processing (NBMP), to Final Draft International Standard (FDIS). With the increasing complexity and sophistication of media services and the incurred media processing, offloading complex media processing operations to the cloud/network is becoming critically important in order to keep receiver hardware simple and power consumption low.

The NBMP standard defines a framework that allows content and service providers to describe, deploy, and control media processing for their content in the cloud by using libraries of pre-built 3rd party functions. The framework includes an abstraction layer to be deployed on top of existing commercial cloud platforms and is designed to be able to be integrated with 5G core and edge computing. The NBMP workflow manager is another essential part of the framework enabling composition of multiple media processing tasks to process incoming media and metadata from a media source and to produce processed media streams and metadata that are ready for distribution to media sinks.

Coded representation of immersive media – Publication of the Technical Report on Architectures for Immersive Media

At its 129th meeting, WG11 (MPEG) published an updated version of its technical report on architectures for immersive media. This technical report, which is the first part of the ISO/IEC 23090 (MPEG-I) suite of standards, introduces the different phases of MPEG-I standardization and gives an overview of the parts of the MPEG-I suite. It also documents use cases and defines architectural views on the compression and coded representation of elements of immersive experiences. Furthermore, it describes the coded representation of immersive media and the delivery of a full, individualized immersive media experience. MPEG-I enables scalable and efficient individual delivery as well as mass distribution, while adjusting to the rendering capabilities of consumption devices. Finally, this technical report breaks down the elements that contribute to a fully immersive media experience and assigns quality requirements as well as quality and design objectives for those elements.

Genomic information representation – WG11 receives answers to the joint call for proposals on genomic annotations in conjunction with ISO TC 276/WG 5

The current ISO/IEC 23092 (MPEG-G) standard series addresses the representation, compression and transport of genome sequencing data. In particular, ISO/IEC 23092 provides a file and transport format, compression technology, metadata specifications, protection support, and standard APIs for the access of sequencing data in the native compressed format.

The effective association of sequencing data with the results of the analysis pipelines expressed by a rich variety of annotations, is still an open problem, not efficiently solved by current file formats or standards. As of today, separate complex post-processing steps need to be applied to possibly very large quantities of genomic sequencing data.

At its 127th meeting, WG11 (MPEG) and ISO TC 276/WG 5 issued a joint Call for Proposals (CfP) addressing the solution of such problem. Answers to the call have been received at the 129th MPEG meeting in Brussels. These proposals have individually shown to provide partial solutions to the problem. Thus, a set of core experiments have been defined so as to integrate the proposed technologies into a single standard specification capable of satisfying all identified requirements and supporting a rich variety of queries. The proposers are fully committed to collaborate for the development and validation of an integrated solution ready for the first standardization step (i.e., Committee Draft) at the 131st MPEG meeting in June/July 2020.

Open font format – WG11 promotes Amendment of Open Font Format to the final stage

Realizing the importance of the text component in media, MPEG has been working on standardization of font formats, in particular ISO/IEC 14496-22 Open Font Format since 2004. The standard has been widely deployed and is supported by virtually all connected devices where text is displayed on screen. At the 129th meeting, WG11 (MPEG) promoted the first amendment of ISO/IEC 14496-22 4th edition to Final Draft Amendment. The 4th edition of the Open Font Format defines a set of technical tools that would be necessary to create fonts that support multiple different languages and writing systems. It enables different applications to reliably parse the font data that may be exchanged as part of the media content (e.g., on the web). This amendment enhances the standard by improving the font tools that are needed to support complex requirements for text layout including specific font features that are designed to support the required functionality for vertical writing.

High efficiency coding and media delivery in heterogeneous environments – WG11 progresses Baseline Profile for MPEG-H 3D Audio

At the 129th meeting, WG11 (MPEG) promoted ISO/IEC 23008-3:2019, Amendment 2 to Draft Amendment status. The Amendment incorporates improvements and corrections on the second edition of MPEG-H 3D Audio standard and introduces a new profile called Baseline profile. The 3D Audio Baseline profile is a subset of the existing Low Complexity profile and supports channel and object signals. It can be signaled in a backwards compatible fashion, enabling interoperability with devices implementing the 3D Audio Low Complexity profile.

The 3D Audio Baseline profile addresses industry demands and is tailored for broadcast, streaming, and high-quality immersive music delivery use cases. In addition to the advanced loudness and Dynamic Range Control (DRC) as well as interactivity and accessibility features supported in the 3D Audio standard, the Baseline profile enables the usage of up to 24 audio objects in Level 3 for high quality immersive music delivery.

Multimedia content description interface – Conformance and Reference Software for Compact Descriptors for Video Analysis promoted to the final stage

Managing and organizing the quickly increasing volume of video content is a challenge for many industry sectors, such as media and entertainment or surveillance. One example task is scalable instance search, i.e., finding content containing a specific object instance or location in a very large video database. This requires video descriptors which can be efficiently extracted, stored, and matched. Standardization enables extracting interoperable descriptors on different devices and using software from different providers, so that only the compact descriptors instead of the much larger source videos can be exchanged for matching or querying. ISO/IEC 15938-15:2019 – the MPEG Compact Descriptors for Video Analysis (CDVA) standard – defines such descriptors. CDVA includes highly efficient descriptor components using features resulting from a Deep Neural Network (DNN) and uses predictive coding over video segments. The standard is being adopted by industry.

At its 129th meeting, WG11 (MPEG) has finalized the conformance guidelines and reference software. The software provides the functionality to extract, match, and index CDVA descriptors. For easy deployment, the reference software is also provided as Docker containers.

Additional Important Activities at the 129th WG 11 (MPEG) meeting

The 129th WG 11 (MPEG) meeting was attended by more than 500 experts from 25 countries working on important activities including (i) a scene description for MPEG media, (ii) the integration of Video-based Point Cloud Compression (V-PCC) and Immersive Video (MIV), (iii) Video Coding for Machines (VCM), and (iv) a draft call for proposals for MPEG-I Audio among others.
