Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) is an international non-profit organisation with the mission of developing standards for Artificial Intelligence (AI)-enabled data coding and for technologies that facilitate integration of data coding components into ICT systems . The MPAI Statutes also assign to MPAI the task to facilitate the creation of patent pools that rely on clear IPR licensing frameworks based on Framework Licences .
MPAI has developed several Technical Specifications relevant to its mission: execution environment of multi-component AI applications, context-based audio enhancements, multimodal human-machine conversation, company performance prediction, neural network watermarking, and governance of the MPAI ecosystem. Four Technical Specifications have been adopted by IEEE without modification and one more is in the pipeline.
MPAI is engaged in several other projects on AI health, connected autonomous vehicles, MPAI metaverse model, and XR Venues. When the functional requirements of a project are consolidated, MPAI principal members adopt a “Framework Licence” that sets some important elements of the future licence for the standard essential patents. Then MPAI issues a Call for Technologies, a document inviting the submission of contributions in response to the Call for Technologies by parties who accept to licence their technologies according to the Framework Licence, if their technologies are accepted to be part of the target Technical Specification.
This document is a Call for Technologies (CfT) for the Connected Autonomous Vehicle (MPAI-CAV) – Architecture Technical Specification. Three documents are attached to this Call for Technologies:
- Use Cases and Functional Requirements: Connected Autonomous Vehicle (MPAI-CAV) – Architecture – .
- Framework Licence: Connected Autonomous Vehicle (MPAI-CAV) – Architecture .
- Template of Responses: Connected Autonomous Vehicle (MPAI-CAV) – Architecture 
Technical Specification: Connected Autonomous Vehicle (MPAI-CAV) – Architecture is the first of a series of Technical Specifications that MPAI intends to develop to promote and support the Autonomous Vehicle industry.
This Call for Technologies: Connected Autonomous Vehicle (MPAI-CAV) – Architecture invites any party wishing to contribute to the development of the planned Technical Specification: Connected Autonomous Vehicle (MPAI-CAV) – Architecture to submit a response. They may do so irrespective of their ownership of technologies that satisfy Functional Requirements of Use Cases and Functional Requirements: Connected Autonomous Vehicle (MPAI-CAV) – Architecture . If they own such technologies, they are required to eventually license their technologies according to Framework Licence: Connected Autonomous Vehicle (MPAI-CAV) – Architecture  if the technologies are selected by MPAI for possible modification and inclusion in the planned Technical Specification: Connected Autonomous Vehicle – Architecture (MPAI-CAV).
Any respondent who is not an MPAI member and wishes to participate in the development of the said Technical Specification shall join MPAI. If they own accepted technologies and do not join MPAI, they lose the opportunity to have their technologies included in the planned Technical Specification: Connected Autonomous Vehicle (MPAI-CAV) – Architecture.
MPAI is not aware of any essential IP in Use Cases and Functional Requirements: Connected Autonomous Vehicle (MPAI-CAV) – Architecture .
The planned Technical Specification: Connected Autonomous Vehicle (MPAI-CAV) – Architecture will be developed using technologies that comply with the following mandatory requirements:
- Be part of responses to this Call submitted by parties accepting Framework Licence: Connected Autonomous Vehicle (MPAI-CAV) – Architecture  and satisfy Use Cases and Functional Requirements: Connected Autonomous Vehicle (MPAI-CAV) – Architecture .
- Be based on technologies specified in published MPAI standards, where relevant, desirable, and feasible .
Therefore, the goal of this Call is to elicit responses in line with the Use Cases and Functional Requirements of .
Respondents are welcome to additionally do one or more of the following:
- Make comments on any technical element of .
- Make motivated proposals of changes or proposal of technologies not included in  if they:
- Are in line with the scope of Use Cases and Functional Requirements: Connected Autonomous Vehicle (MPAI-CAV) – Architecture .
- Satisfy the Framework Licence .
At this stage, MPAI membership is not a prerequisite for responding to this Call for Technologies. However, proponents should be aware that, if their proposal or part thereof is accepted for inclusion in the planned Technical Specification: Connected Autonomous Vehicle (MPAI-CAV) – Architecture, they will be requested to immediately join MPAI, or lose the opportunity to have their accepted technologies included in the standard.
MPAI will select the most suitable technologies based on their technical merits. However, MPAI in not obligated, by virtue of this Call, to select a particular technology or to select any of the proposed technologies if those submitted are found inadequate.
Those planning to respond to this Call are:
- Advised that the Call for Technologies: Connected Autonomous Vehicle (MPAI-CAV) – Architecture will be presented at two online events on 2023/07/26.
- Requested to communicate their intention to respond to this Call with an initial version of the form of Annex A to the MPAI secretariat (email@example.com) by 2023/07/31. Submission of a duly filled out Annex A helps MPAI to properly plan for the revision of submissions. This, however, is not a requirements and the submission of a respondent to this Call who did not the submit Annex A will still be accepted.
- Encouraged to regularly visit the Call for Technologies webpage where relevant additional information will be posted.
- Required to deliver their submissions to the MPAI secretariat (firstname.lastname@example.org) by 2023/07/10 T23:59 UTC. The secretariat will acknowledge receipt of the submission via email.
- Required to attend the review of submissions according to the schedule that the 35th MPAI General Assembly (MPAI-35) will define at its online meeting on 2023/07/12. For details on how non MPAI members who have made a submission can attend the said review sessions should contact the MPAI secretariat (email@example.com).

Additional remarks: (points of importance not covered above.)
The submission features in Table 3 are explained in the following Table 4.
Table 4 – Explanation of submission features
|Completeness of description||Evaluators should:
1. Compare the list of requirements (Annex C of the CfT) with the submission.
2. Check if respondents have described in sufficient detail how the requirements are supported by the proposal.
Note: Submissions will be judged for the merit of what is proposed. A submission on a single technology that is excellent may be considered instead of a submission that is complete but has a less performing technology.
|Understandability||Evaluators should identify items that are demonstrably unclear (inconsistencies, sentences with dubious meaning etc.)|
|Extensibility||Evaluators should check if respondent has proposed extensions to the Use Cases.
Note: Extensibility is the capability of the proposed solution to support use cases that are not supported by current requirements.
|Use of standard Technology||Evaluators should check if new technologies are proposed where widely adopted technologies exist. If this is the case, the merit of the new technology shall be proved.|
|Efficiency||Evaluators should assess power consumption, computational speed, computational complexity.|
|Test cases||Evaluators should report whether a proposal contains suggestions for testing the technologies proposed.|
|Relative complexity||Evaluators should identify issues that would make it difficult to implement the proposal compared to the state of the art.|
