Overview
ISO/IEC 14496-5:2001/Amd 35:2015 is an important amendment to the international standard focused on information technology for coding audio-visual objects. This amendment specifically updates Part 5: Reference software of the MPEG-4 standard, introducing the 3D-AVC Reference software which supports advanced video compression technologies like Multiview Depth High profile and 3D-AVC profile.
Developed by the joint technical committee ISO/IEC JTC 1, Subcommittee SC 29, this standard amendment enhances the visual encoding and decoding software to accommodate three-dimensional video coding. The updated reference software facilitates optimized handling of 3D video data, making it essential in modern multimedia and broadcasting applications dealing with stereoscopic and multiview content.
Key Topics
-
3D-AVC Reference Software
The amendment replaces previous versions of the 3D video reference software (3DV-ATM_13_1) with the updated 3DV-ATM_14_0 version. This update includes:
- Support for the Multiview Depth High profile, enabling efficient compression of multiview video streams with depth information.
- Full compatibility with the 3D-AVC profile, allowing for advanced 3D video rendering and transmission.
-
Visual Encoder and Decoder Enhancements
Both visual encoding and decoding components have been upgraded in the reference software, written in C programming language, ensuring robust implementation and ease of integration into diverse systems.
-
Electronic Attachment
The amendment includes an electronic attachment integral to the document, containing the updated reference software code required to implement the new capabilities.
Applications
This amendment and updated reference software serve critical roles in fields where advanced 3D video coding is a priority:
