Proposal for MPEG4 AVC Compression Format Standardization in

Proposal for MPEG-4 AVC Compression Format Standardization in DICOM 2008/03/19 Matsushita Electric Industrial Co. , Ltd. KARL STORZ GMBH & CO. KG

MPEG-4 AVC/H. 264 n n n 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 p p p 2008/3/19 p 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 ü E. g. depending on encoder settings, similar (or even lower) complexity than MPEG-2 can be achieved ü 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: ü Optical disk (BD-ROM, AVCHD, AVCRec), ü HD broadcast (DVB/ATSC/ARIB. . France, UK, Northern Europe etc. ）, ü 3 GPP, broadcast for mobile devices (1 -Seg, Korean DMB, DVB-H） Application in: ü Hardware ü HD encoder: SONY, Panasonic, Fujitsu, NEC, NTT, LSI Logic etc. ü HD decoder: Almost all major manufacturers ü Software ü HD decoder: Apple, Macromedia, Corel, Cyberlink, Sonic… ü HD encoder: Main. Concept, Nero, Quick. Time, … ü Products：PS 3, BD recorder / player, TV, STB, Camcorder, … Licenses: Main license by MPEG-LA 2

DICOM and MPEG-4 AVC/H. 264 n n 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 n n n 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 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 2008/3/19 3
