MPEG Advances Immersive Audio, AES-256 Encryption, AI Media Coding Standards
At its 154th meeting, MPEG advanced multiple standards including AVC 12th edition, AES-256 encryption for ISOBMFF, and the AAC Immersive Interchange Format (IIF), alongside new developments in AI-based media coding and 3D graphics. These updates enhance capabilities in video coding, content protection, immersive audio, and AI applications for streaming media. The meeting also featured demonstrations highlighting the readiness of MPEG-I immersive audio technology for deployment across various devices.
Key Takeaways
- AVC 12th edition (H.264 V16) reached Final Draft International Standard, adding support for 11 new SEI messages from VSEI standard.
- AES-256 encryption for ISOBMFF advanced to Final Draft Amendment, offering a more secure option for content protection.
- AAC Immersive Interchange Format (IIF) and Media Authenticity moved to FDAM status, enabling reliable low-latency immersive audio transmission and verification.
- New Committee Drafts were issued for Feature Coding for Machines (FCM) to compress intermediate feature data in AI split inference, and for an Amendment to Neural Network Coding (NNC) for generalized tensor data compression.
- Geometry-based Point Cloud Coding for Solid Objects and Gaussian Splat Coding amendments for G-PCC and V-PCC progressed to Committee Draft stages, targeting efficient 3D object and immersive scene representation.
Why It Matters
MPEG's latest advancements provide new tools for enhancing streaming video quality, security, and immersive content delivery. The move to AES-256 for ISOBMFF offers a more robust content protection mechanism, while the finalized AVC 12th edition improves video coding capabilities. Progress in AI-based media coding standards like FCM and NNC could significantly optimize distributed processing for computer vision applications. Ongoing development in immersive audio and 3D graphics, particularly with Gaussian Splats, indicates a continued push towards more realistic and interactive experiences. Watch for these standards to integrate into next-generation codecs and content delivery workflows, influencing both performance and the creative potential of streaming platforms.
