Standards that innovate technology and standardisation

  • Post author:

At its 40th General Assembly (MPAI-40), MPAI approved one draft, one new, and three extension standards. For an organisation that has already nine standards in its game bag, this may not look like big news. There are two reasons, though, to consider this a remarkable moment in the MPAI short but intense life. The first reason is that the draft standard posted for Community Comments – Human and Machine Communication (MPAI-HMC) – does not specify new technologies but leverages technologies…

Connected autonomous vehicles can be connected to the metaverse

  • Post author:
  • Post category:MPAI

In a previous article, Ihave described the Architecture of the MPAI Connected Autonomous Vehicle (CAV). The CAV’s Environment Sensing Subsystem (ESS) captures data of the environment with a variety of sensors and produces the Basic Environment Representation (BER) that is passed to the Autonomous Motion Subsystem (AMS). This exchanges (subsets of) the BER with other CAVs in range and uses the received information to produce the Full Environment Representation (FER). Then, the AMS can issue commands to the Motion Actuation Subsystem…

Thirty years ago, in MPEG

  • Post author:
  • Post category:MPEG

In November 1992, MPEG had already christened the first three parts of its first MPEG-1 standard: the System, Video, and Audio triad. The approval of those three standards did not mean the end of MPEG-1 because work continued with Conformance and Reference Software. These two projects, however, would have been too little for MPEG people hungry for new challenges. Indeed, there as a reason if in July 1990 MPEG has started exploring the “MPEG Second Work Item”. In November 1991,…

Visiting MPAI standards: the MPAI Metaverse Model foundations

  • Post author:
  • Post category:MPAI

Much has been and is being said about the vagueness of the “metaverse” notion . To compensate for this, the current trend is to add an adjective to the “metaverse” name. So, now we have studies on industrial metaverse, medical metaverse, tourist metaverse, and more. In the early phases of its metaverse studies, when it was scoping the field, MPAI did consider 18 metaverse domains (use cases). Now, however, that phase is over because the right approach to standards is…

Visiting MPAI standards – Connected Autonomous Vehicles (MPAI-CAV) – Architecture

  • Post author:
  • Post category:MPAI

Introduction MMPAI-36 (September 2023) has approved the publication of five standards. Two are extensions of already published standards (and adopted by IEEE without modifications) and three brand new. This is an overview of the main content of one of the new standards, Technical Specification: Connected Autonomous Vehicles – Architecture (MPAI-CAV). MPAI works on CAV standards because replacing current vehicles with CAVs is desirable from many viewpoints. CAVs are expected to offer a safer drive by replacing human errors with machine…

XR Venues – Live Theatrical Stage Performance

  • Post author:
  • Post category:MPAI

Scope MPAI has issued a Call for Technologies seeking proposals for MPAI-XRV – Live Theatrical Stage Performance, an MPAI standard project seeking to define interfaces of AI Modules (AIM) facilitating live multisensory immersive stage performances. 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. Setting An implementation of MPAI-XRV – Live Theatrical Stage Performance includes:…
