Title: Standard for Compact Feature Representation for Collaborative Driving in V2X Autonomous Driving Systems

Scope: This standard defines a compact feature representation architecture designed for feature fusion based collaborative driving within Vehicle-to-Everything (V2X) autonomous driving systems. It specifies feature data formats, metadata formats, and interface protocols for interoperability. The standard also specifies metrics to evaluate the trade-off between transmission efficiency and collaborative task performance.

3404 WG- Data and Model of Multiple Computing Centers

The 9^th 3404 WG Plenary Meeting was held on August 21. Attendees fully discussed 1 contribution on 3404.2, which was approved.

3483 WG- Multi-Modality Feature Coding

The 6th IEEE 3483 WG Meeting was held on August 22. Attendees fully discussed 2 received contributions this time. All of them were rejected.

Approval of New PAR of Holographic Video Coding (DCSC-29-N0004)

Motion to approve new PAR of Holographic Video Coding. (Mover: Ruochen Li; Second: Jun Peng). Prof. Rongang Wang presented the PAR. It was unanimously approved as presented, but it is recommended to communicate with the video group in a separate meeting

Title: Standard for Holographic Video Coding

Scope: The standard defines a sef of tools for efficient representation and coding of holographic video, the corresponding definitions of syntax, semantics, parsing and decoding procedure. The holographic video should support both 6DoF interaction and photorealistic virtual viewpoint rendering. The holographic video content includes but not limited to multi-view video sequences, multi-view video plus depth and neural representation like 3D/4D gaussian splatting.

Approval of New PAR of Data Intelligence for Smart Grid (DCSC-29-N0005)

Motion to approve new PAR of Data Intelligence for Smart Grid. (Mover: Ruochen Li; Second: Jun Peng). Guang Tian presented the PAR. It is suggested to further clarify the requirements, and this proposal will not be approved at this time.

Title: Standard for Data Intelligence of Smart Grid

Scope: The working group focus on establishes a framework for applying Data Intelligence (DI) technologies to power grid systems. It covers the use of DI for real-time monitoring, fault detection, infrastructure inspection, situational awareness, and decision support in transmission, distribution, and smart grid operations. The standard defines data formats, algorithmic requirements, performance metrics, and integration protocols to ensure interoperability, safety, and scalability across grid applications. It addresses challenges such as environmental variability, edge processing, and cybersecurity while promoting AI transparency and reliability in critical infrastructure.

Next Meetings

The next meeting is tentatively scheduled in December 2025. (The meeting notice will be published on our website one month before the meeting). Remote attendees can request to set up a teleconference service at least one week before the meeting.

This meeting minutes was approved on the meeting.
