ISO/IEC 23090-10:2022

Overview

ISO/IEC 23090-10:2022 specifies the carriage (packaging and transport) of coded volumetric visual media that conform to visual volumetric video‑based coding and video‑based point cloud compression (as defined in ISO/IEC 23090‑5). The standard defines how V3C (visual volumetric video coding) bitstreams, atlas data and related metadata are encapsulated, referenced and delivered for playback, streaming and storage in modern media file and streaming architectures.

Keywords: ISO/IEC 23090-10, V3C, volumetric video, visual volumetric video-based coding, video-based point cloud compression, carriage, immersive media, V-PCC.

Key Topics and Technical Requirements

• Overall carriage architecture: Referenceable code points such as brands, URNs, scheme restrictions, sample entry and box types for consistent identification and interoperability.
• Volumetric media structures: Definitions for volumetric visual media headers, sample entries and sample groups that describe how volumetric frames and units are represented.
• Decoder configuration and headers: V3C decoder configuration record and box, V3C unit header box and atlas parameter set groups required for correct decoding.
• Single-track and multi-track encapsulation: Mechanisms for encapsulating an entire V3C bitstream in a single track or splitting atlas, tile and component data across multiple tracks for parallelism and selective access.
• Atlas and tile handling: Sample entry formats for V3C atlases and tiles, tile mapping and storage conventions to support tiled delivery and partial data retrieval.
• Partial access and spatial indexing: Structures for spatial region bounding boxes, tile mapping, object collections and dynamic spatial region information that enable selective streaming and low-latency viewport delivery.
• Viewport and camera metadata: Timed and non‑timed metadata formats for intrinsic/extrinsic camera data and viewport descriptions to support efficient rendering in VR/AR/6DoF applications.
• Track references and grouping: Track alternatives, track grouping and playout groups to support object switching, multi-resolution delivery and adaptive streaming.

Practical Applications and Who Uses It

This standard is essential for the delivery and playback of immersive 3D video content in applications such as:

• VR/AR and mixed-reality streaming platforms
• 6DoF volumetric video and 3D telepresence services
• Interactive entertainment and gaming with volumetric assets
• Broadcast and OTT workflows that incorporate point-cloud or volumetric scenes
• Content production tools and media packagers preparing files for distribution

Typical users:

• Codec and decoder implementers (V3C/V‑PCC)
• Media packaging and streaming engineers
• Video platform architects and CDN operators
• Device and headset manufacturers integrating volumetric playback
• Content creators and post‑production vendors

Related Standards

• ISO/IEC 23090‑5 - visual volumetric video‑based coding and video‑based point cloud compression (referenced normative specification).
• Media file format and streaming specifications that define boxes, sample entries and timed‑metadata conventions used in carriage implementations.

ISO/IEC 23090‑10 provides the carriage rules that enable interoperable, efficient transport of volumetric video for immersive media ecosystems.
