Overview

ISO/IEC FDIS 23090-19 is an international standard from ISO and IEC that provides reference software for Video-based Point Cloud Compression (V-PCC) within the framework of ISO/IEC 23090-5. This document is part of the broader MPEG 3D graphics and haptics coding ecosystem, supporting the representation, compression, and interoperable exchange of immersive media, especially visual volumetric content. The reference software includes both encoder and decoder demonstrations, aiding implementers in understanding, verifying, and utilizing the V-PCC coding standard.

Key Topics

• Reference Software Provision
  The standard includes reference software as an electronic attachment, encompassing practical implementations for V-PCC conforming to ISO/IEC 23090-5.

• Purpose of Reference Software

  • Facilitates study and clarification of ISO/IEC 23090-5
  • Demonstrates encoding and decoding behaviour according to the standard
  • Enables testing and verification of bitstreams for conformance and interoperability
  • Acts as a baseline for evaluating independent implementations

• Definitions and Scope

  • Encoder: Produces V-PCC conformant bitstreams, not specified in detail within the software package.
  • Decoder: Processes bitstreams according to specified decoding requirements (display not in scope).
  • Covers “Visual volumetric video-based coding” (V3C) and V-PCC

• Updates in This Edition

  • Bug fixes for attribute smoothing and packet loss recovery (PLR)
  • Enhanced support for high bit depth sequences

• Availability and Access

  • The reference software package and user manual are provided as downloadable attachments supporting practical application and deployment.

Applications

Implementing the ISO/IEC 23090-19 reference software supports a variety of practical uses in the field of immersive media and 3D graphics:

• Conformance Testing
  Developers can use the software to verify that new encoders or decoders comply with the V-PCC specification in ISO/IEC 23090-5, ensuring robust interoperability.

• Research and Development
  The provided encoder and decoder examples help researchers and engineers to prototype, optimize, and evaluate new algorithms or hardware designs for point cloud compression.

• Educational Purposes
  The software serves as a valuable educational resource, demonstrating the processing workflows and expected outputs of V-PCC compression and decompression.

• Benchmarking and Quality Assessment
  The reference implementation offers a standard baseline for performance comparison of new or commercial solutions against a recognized industry benchmark.

Related Standards

For a comprehensive approach to immersive media coding, ISO/IEC FDIS 23090-19 should be understood in context with the following related standards:

• ISO/IEC 23090-5
  • Information technology - Coded representation of immersive media - Part 5: Visual volumetric video-based coding (V3C) and video-based point cloud compression (V-PCC)
• Other ISO/IEC 23090 Series Parts
  These address different aspects of immersive media, including scene description, streaming, and interactivity.

Practical Value

By offering official reference software, ISO/IEC FDIS 23090-19 enables stakeholders to:

• Accelerate product and tool development for 3D point cloud compression
• Ensure consistent global deployment of V-PCC technology
• Reduce ambiguities in interpreting and implementing the V-PCC standard
• Support innovation in applications such as virtual reality (VR), augmented reality (AR), immersive video, and advanced multimedia communications
