Overview
ISO/IEC 23000-11:2009/Amd 3:2014 is an amendment to the international standard that defines the Stereoscopic Video Application Format (Stereoscopic Video AF) within the MPEG-A (Multimedia Application Format) suite. Developed by ISO and IEC, this amendment specifically introduces support for movie fragment structures in stereoscopic video content, enabling advanced handling and management of 3D video assets. This addition enhances flexibility and interoperability for various multimedia applications leveraging stereoscopic (3D) video.
Compliance with ISO/IEC 23000-11:2009/Amd 3:2014 is essential for those developing, exchanging, or deploying picture and video coding solutions and devices that utilize multimedia application formats, particularly for applications involving stereoscopic (3D) video.
Key Topics
- Stereoscopic Video AF: The standard targets the structure and description of multimedia files containing stereoscopic video, supporting both purely 3D content and stereo-monoscopic mixed sequences.
- Movie Fragment Support: The amendment allows segmentation of video streams into individual fragments or samples, facilitating random access, adaptive streaming, and improved resource management.
- File Structure & Brands: Defines conformance brands ('ss01', 'ss02', and 'ss03') that distinguish between fully 3D content, mixed content, and advanced grouping/composition types in file structures.
- Media Information Boxes:
- ‘svmi’ (Stereoscopic Video Media Information Box): Stores metadata about stereoscopic video sequences, the arrangement of left/right views, and the sequence type.
- ‘scdi’ (Stereoscopic Camera and Display Information Box): Optionally records technical parameters for stereoscopic capture and presentation, including camera setup and display safety details.
- Grouping and Sample Entry: Enhances file organization and resource referencing through grouping mechanisms and sample group entries, which indicate stereoscopic composition and relevant camera/display information.
- High Efficiency Video Coding (HEVC): The addition links to other key standards for efficient video compression and delivery in heterogeneous environments.
Applications
- 3D Video Distribution: Facilitates standardized storage and distribution of stereoscopic (3D) movies and video streams for use in cinema, broadcast, streaming, and downloadable content.
- Content Creation and Editing: Enables multimedia editors to package, annotate, and edit stereoscopic and mixed 3D/2D video with full interoperability, supporting industry workflows.
- Adaptive and Interactive Media: The movie fragment and sample resource referencing features support random access and adaptive streaming, important for on-demand video services and interactive multimedia platforms.
- 3D Displays and VR Devices: Ensures consistent presentation of 3D video content across a range of consumer and professional devices, including stereoscopic televisions, VR/AR headsets, and mobile devices.
- Archival & Exchange: Promotes long-term preservation and reliable exchange of stereoscopic video content through well-defined formats and metadata.
