AVC Compression Update: FRExt and future Matthew Goldman Vice President of Technology Compression Systems

© TANDBERG Television Inc. MPEG-4 AVC / H.264 Version 1 ISO/IEC [MPEG-4 Part 10] = ITU-T Rec. H.264 Primary Technical Objectives Significant improvement in coding efficiency High loss/error robustness Transport independent (network abstraction) Convey over MPEG-2 Transport, RTP, H.32x, MP4/ISO file formats, MP4 Systems Low latency capability (but better quality for higher latency) Exact match decoding 3 Profiles ( example application) Baseline Video conferencing & wireless Main Broadcast & Storage (standard & high definition) Extended Streaming Finalized May/July 2003 (tech frozen 12/02) Products available today

© TANDBERG Television Inc. MPEG-4 AVC / H.264 Version 2 Fidelity Range Extensions (FRExt) Additional Technical Objectives Professional applications > 8b/sample, > 4:2:0 color sampling, Higher-quality high-resolution video Alpha plane support (a degree of object functionality) New supplemental information 4 Profiles High (4:2:0, 8b) Brdcst/Storg SD/HD (MP superset) High 10 (4:2:0, 10b) High 422 (4:2:2, 10b) Contribution High 444 (4:4:4 12b) Finalized July 2004 High Profile will be in products this year 4:2:2 when? Hi444 withdrawn and to be replaced!

© TANDBERG Television Inc. MPEG-4 AVC / H.264 Extensions Current Activities Scalable Video Encoding Effort launched January 2005 Core experiments exploring Context Adaptive Variable Length Coding (CAVLC) Inter-layer motion prediction Inter-layer texture prediction Region of Interests (ROI) Quantization High-level syntax Improved and low-delay Fine Granularity Scalability (FGS) Replacement 4:4:4 Profile for Hi444 Better processing elements for color components (Cb/Cr channels) Improved macroblock coding mode

© TANDBERG Television Inc. Future Activities – Rumors? Heard rumors about a new codec to replace MPEG-4 AVC/H.264? H.265 Muddled information taken out of context Standards activities always investigate future possibilities There will likely by additional enhancements/amendments to AVC Just like what occurred with FRExt (v2) and is happening now with SVC, new 4:4:4 Profile
