Giesen, 13.06.20032 Extended DVD Specification DVD-Forum is working on an extended DVD Specification („DVD V2.0“) Enhanced DVD is based on current DVD- ROM physical specification: Red Laser Larger Data Transfer Rate Main Feature: Support of HDTV Resolution Proposed: Enh. Audio Coding Schemes: DD+, DTS+

7. CoC Video Compression Systems, Dr. Jan H. Giesen, 13.06.20037 HD/DVD9 proposals (7Mb/s) MPEG2 –Mitsubishi H.264 ( = AVC, MPEG4 ISO/IEC 14496 -10,) –Apple, Pioneer, Sand Video, Toshiba MPEG4 ASP –DIVx, iVAST, JVC WMV9 –MicroSoft - DemoGrafx DVD compatible: SD MPEG2 + HD H.264 –Philips, Thomson

8. CoC Video Compression Systems, Dr. Jan H. Giesen, 13.06.20038 Video Format: MPEG4 AVC Proposed by Toshiba Main Profile, Level 4.I: –I + P picture types, In-loop deblocking,1/4 sample motion compensation, VLC-based entropy coding, Tree-structured motion segmentation down to 4x4 block size, 4:2:0 –Bi-predictive slices, CABAC, Weighted prediction, Adaptive block-size transforms –Interlace pictures, frame/field adaptive at picture and macroblock level

9. CoC Video Compression Systems, Dr. Jan H. Giesen, 13.06.20039 Video Format: MPEG4 AVC Restrictions to Level Limits: –Max bitrate: 29.4Mbps instread of 50Mbps –CPB buffer size: 30Mbits instead of 62.5Mbits –Prediction (GOVU) structure. AVC encapsulation into MPEG2 PS: –Encapsulation as MPEG video stream –STREAM_ID: 0xE1 (DVD MPEG2 Video Stream ID: 0xE0)

10. CoC Video Compression Systems, Dr. Jan H. Giesen, 13.06.200310 Video Format: WMV9 Proposed by Microsoft WMV9 encapsulation into MPEG2 PS: –Extended STREAM_ID: 0xFD as defined in ISO/IEC 13818-1:2000/FPDAM –Stream ID Extension field in PES Header –Not compatible to existing mechanism to encapsulate “private” streams in DVD VOBs

15. CoC Video Compression Systems, Dr. Jan H. Giesen, 13.06.200315 Conclusions HD movies on DVD9 @ 7-10Mbs is feasible with good Quality Also feasible in DVD backwards compatible way using dual layer MP2/AVC or even MP2/MP2. Picture quality @ DVD9 bitrates (all codecs) is NOT seen as sufficient by Studios. Currently only MPEG2 @ 20-24Mbs is seen as sufficient by Studios  more interest in Blue Laser Disc Formats than in HD on DVD9
