Geneva, Switzerland – 23 August 2023. The international, non-profit, and unaffiliated Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) organisation developing AI-based data coding standards has concluded its 35th General Assembly (MPAI-35) approving the publication of three Calls for Technologies and five Technical Reports with request for Community Comments. The table gives links to the documents, dates of and registration links to online presentations and deadlines for submitting responses to Calls and comments on Standards.

Anybody may respond to any of the three Calls for Technologies. However, non-members should join MPAI to participate in the development of the relevant standards.

Anybody can make comments on the Technical Specifications published with a request for Community Comments.
MPAI is continuing its work plan comprising the development of the following Technical Specifications:

1. The AI Framework (MPAI-AIF V2 Technical Specification will enable an implementer to establish a secure AIF environment to execute AI Workflows (AIW) composed of AI Modules (AIM).
2. The Avatar Representation and Animation (MPAI-ARA V1 Technical Specification will support creation and animation of interoperable human-like avatar models expressing a Per-sonal Status.
3. The Multimodal Conversation (MPAI-MMC V2 Technical Specification will generalise the notion of Emotion by adding Cognitive State and Social Attitude and specify a new data type called Standard for Personal Status.
4. The Call for Technologies of the MPAI-Metaverse Model (MPAI-MMM – Architecture is being prepared and is expected to be published soon.

The MPAI work plan also includes exploratory activities, some of which are close to becoming standard or technical report projects:

1. AI Health (MPAI-AIH Targets an architecture where smartphones store users’ health data processed using AI and AI Models are updated using Federated Learning.
2. Connected Autonomous Vehicles (MPAI-CAV Targets the Human-CAV Interaction En-vironment Sensing, Autonomous Motion, and Motion Actuation subsystems implemented as AI Workflows.
3. End-to-End Video Coding (MPAI-EEV Extends the video coding frontiers using AI-based End-to-End Video coding.
4. AI-Enhanced Video Coding (MPAI-EVC Improves existing video coding with AI tools for short-to-medium term applications.
5. Server-based Predictive Multiplayer Gaming (MPAI-SPG Uses AI to train neural net-works that help an online gaming server to compensate data losses and detects false data.
6. XR Venues (MPAI-XRV Identifies common AI Modules used across various XR-enabled and AI-enhanced use cases where venues may be both real and virtual.

Legal entities and representatives of academic departments supporting the MPAI mission and able to contribute to the development of standards for the efficient use of data can become MPAI members.
