A Message from the President
VRIF into the Metaverse Interop Madness
|Immersive technologies and XR devices are the gateway to interact with virtual worlds and metaverses. With more advance technology, the better is the interaction and user interface. A fundamental aspect of the metaverse is the social interaction between different users and the virtual worlds; thus, connectivity is key to transport the user to a virtual experience in real time. The Metaverse ecosystem is diverse and there are several stakeholders that address different parts of this ecosystem, ranging from applications, platforms, technology, devices, and connectivity providers. The figure below illustrates this ecosystem.|
|Interoperability is not an easy task, since there are many formal standards, de facto industry standards, and proprietary solutions and services from different parts of the value chain that are trying to coexist. Just by looking at the figure, the first though that comes to our mind: this is an “interop madness”; to fix this, it requires a tremendous effort from the entire ecosystem to solve this issue.|
Since its inception, VRIF’s main goal has been to improve interoperability for immersive services (such as VR streaming). We only address a specific part of the metaverse ecosystem: areas such as media technology and connectivity, as described above, are fundamental parts of this interoperability madness. VRIF remain focused on its original vision, we think that our four parallel tracks: VR360, Volumetric, Social VR and 5G Cloud are essential for the success of Metaverse interoperability.
Since we strive for a more open ecosystem, we are happy to announce that VRIF has joined the Metaverse Standards Forum as a participant member in an effort to continue our mission: “To further the widespread availability of high quality audiovisual VR experiences, for the benefit of consumers”
 Note that this ecosystem is for illustration purposes; it is not intended to be at all an exhaustive list.
Updates on immersive video standardization in MPEG: A new Mesh Coding standard on the horizon
|Over the last years, ISO/IEC JTC1 SC29, also known as the Motion Picture Expert Group (MPEG), has been actively working on various compression standards for distribution of immersive visual data. These standards are collected in the Visual Volumetric Video-based Coding (V3C) family of standards and cover a variety of use cases: Compression of individual objects represented as 3D dynamic point clouds, Video-based Point Cloud Coding (V-PCC)Coding immersive scenery, known as MPEG Immersive Video (MIV)Carriage and delivery mechanisms for V3C coded data.And, most recently, compression of dynamic 3D mesh representations.While V-PCC, MIV and carriage of V3C data have already matured and been released as the ISO/IEC standards 23090-5, 23090-12, and 23090-10, respectively, the work for a new standard on dynamic mesh compression has just started. At the MPEG meeting in April 2022, several proposed solutions have been evaluated. And at the most recent MPEG meeting in July the starting point and software test model for the joint standardization activity has been agreed upon.|
Five companies have presented their solutions for dynamic mesh coding. Based on subjective and objective coding performance evaluation, one proposal has been selected as the basis for the collaborative standardization work. Based on the V3C framework, this proposal simplifies a 3D mesh first, before encoding the base mesh using known mesh coding solutions, such as Edgebreaker. Additional information, so-called displacement maps, is encoded as video streams and used at the decoder to reconstruct the original mesh fidelity from the simplified base mesh. Texture information is also coded as video streams and completes the codec design. Based on its heavy utilization of video-coding technology, the name for this new standard was decided as “Video-based dynamic mesh coding (V-DMC).” MPEG plans to finalize this new standard by the end of 2024.
Overview articles on the other V3C standards can be found here:
 VRIF has released Volumetric Video Guidelines on these standards (https://www.vr-if.org/guidelines/).
