Geneva, Switzerland – 22 November 2023. MPAI, Moving Picture, Audio and Data Coding by Artificial Intelligence, the international, non-profit, and unaffiliated organisation developing AI-based data coding standards has concluded its 38th General Assembly (MPAI-38) approving the release of a new version of its Neural Network Watermarking reference software and the start of the development of the new XR Venues – Live Theatrical Stage Performance standard.

The new version of the Neural Network Watermarking (MPAI-NNW reference software makes it possible to upgrade conventional AI-based processing workflows with traceability and integrity checking functions. For instance, it is now possible to add AI Modules to an MPAI-AIF workflow to detect whether a particular text was indeed produced by the expected service or AI Module (AIM). Register at to attend the online presentation on 2023/12/12T15:00 UTC.

The XR Venues (MPAI-XRV) – Live Theatrical Stage Performance ( standard project specifies functions and interfaces of AI Modules designed to automate live multisensory immersive stage performances which ordinarily require extensive on-site show control staff to operate. By running AI Workflows (AIW) composed of AIMs, it will be possible to obtain a more direct, precise yet spontaneous show implementation and control of multiple complex systems to achieve the show director’s vision.

MPAI is continuing its work plan that involve the following activities:
1.AI Framework (MPAI-AIF reference software, conformance testing, and application areas.
2. AI for Health (MPAI-AIH development of the standard.
3. Context-based Audio Enhancement (CAE-DC new projects.
4. Connected Autonomous Vehicle (MPAI-CAV Functional Requirements of CAV architecture.
5.Compression and Understanding of Industrial Data (MPAI-CUI preparation for extension of existing standard.
6. Multimodal Conversation (MPAI-MMC reference software, drafting conformance test-ing, and new areas.
7. MPAI Metaverse Model (MPAI-MMM reference software and metaverse technologies requiring standards.
8. Neural Network Watermarking (MPAI-NNW reference software for enhanced applications.
9. Portable Avatar Format (MPAI-PAF reference software, conformance testing and new areas.
10. End-to-End Video Coding (MPAI-EEV video coding using AI-based End-to-End Video coding.
11. AI-Enhanced Video Coding (MPAI-EVC video coding with AI tools added to existing tools.
12. Server-based Predictive Multiplayer Gaming (MPAI-SPG technical report on mitigation of data loss and cheating.
13. XR Venues (MPAI-XRV preparation for the development of the standard.
