  2. MPEG-4 AVC/H.264 • MPEG-4 AVC is a widely used standard for video compression, and there are many products using this standard. • Since it has been adopted into the HD broadcast and HD optical disk standards, it can be expected that it will be the main standard especially for HD devices. • Some more facts • Year of standardization: MPEG-4 AVC Main Profile in 2004, High Profile in 2005 • The compression ratio is approx. 2 times higher than in MPEG-2 • Trade-off between complexity and compression ratio gain is scalable • E.g. depending on encoder settings, similar (or even lower) complexity than MPEG-2 can be achieved • Appropriate parameters can be pre-set by the encoder engine and can also be recommended in an informative section of the DICOM supplement • Standards in which it is applied: • Optical disk (BD-ROM, AVCHD, AVCRec), • HD broadcast (DVB/ATSC/ARIB.. France, UK, Northern Europe etc.）, • 3GPP, broadcast for mobile devices (1-Seg, Korean DMB, DVB-H） • Application in: • Hardware • HD encoder: SONY, Panasonic, Fujitsu, NEC, NTT, LSI Logic etc. • HD decoder: Almost all major manufacturers • Software • HD decoder: Apple, Macromedia, Corel, Cyberlink, Sonic… • HD encoder: MainConcept, Nero, QuickTime, … • Products：PS3, BD recorder / player, TV, STB, Camcorder, … • Licenses: Main license by MPEG-LA

  3. DICOM and MPEG-4 AVC/H.264 • It is expected that the DICOM standard for an HD video compression format will be used in the next 10 years. Thus, a widely adopted standard with the highest compression ratio should be used. • On the Internet, compression formats with a compression performance similar to MPEG-4 AVC are available • If solely MPEG-2 would be standardized, there is a possibility that such compression formats would be used as de-facto standards. • If MPEG-4 AVC would be standardized, such kind of confusion could be avoided, because there is no other compression format that is superior from a compression ratio- as well as from practical point of view. • Since there are already many devices that are MPEG-4 AVC compliant, there will be many advantages such as ensuring interoperability. Proposal: Standardize MPEG-4 AVC / H.264 in DICOM
