Schema 5th TC Meeting Ipswich, February 2004 Main achievements in last meetings 63 rd Awaji Is. (JP, Dec 2002) FCD ITU-T Rec H.264 /ISO Advanced Video Coding (AVC) FCD REL/RDD MPEG-21 Testbed: MPEG-4 over IP (8), IPMP ext, DIA/streaming 64 th Pattaya (TH, March 2002) FDIS ITU-T Rec H.264 /ISO Advanced Video Coding (AVC) Improvement in compression performance for general coding Applications: Video Comm, DigitalTV, HDTV, video streaming, DVD… MPEG-4 High Efficiency AAC (HE-AAC) MP4 file format MPEG-7 Reference Software extensions (FPDAM) Calls: Evidence on Scalable Video Coding Advances (MPEG-4) CfP for Extended Sample Bit Depth and Chroma Format in AVC (JVT)

Schema 5th TC Meeting Ipswich, February 2004 Main achievements in last meetings 66 th Trondheim (NO, Jul 2003) FDIS MPEG-4, Part 9: Reference Hardware Description CD MPEG-4, Part 17: Streaming text format Calls: Call for Proposals on Lossless Coding of 1-bit Audio Signals Main activities: MPEG-21: Completion of Parts 5 and 6, the Rights Expression Language (REL) and its associated Rights Data Dictionary (RDD) MPEG-2 and –4: MPEG Systems support for AVC, 'Error-resilient Simple Scalable Profile' in part 2. Also MPEG Reference Hardware.
