Headquarter Geneva Towards Draft Standard ITU T dates o All 3 documents recently achieved FCD status o FCD status means VC 1 specification is technically stable and opens the gates to DS Draft Standard balloting o Reference decoder implementation and conformance bit streams available to SMPTE members ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva Other Standards and Consortia ITU T DVD Forum Group mandated MPEG 2 VC1 and H 264 for next gen HD DVD players Blu ray Group mandated MPEG 2 VC1 and H 264 as formats for next gen BD players Group mandated only VC 1 VC 1 optional in DLNA becoming part of DVB spec set under ATSC consideration Rapidly growing ecosystem support for VC 1 FVD Other Benefit dates ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva Chips and DSPs

Geneva VC 1 vs H 264 Quality ITU T o Both codecs approximately 2 3x better than MPEG 2 2x better than MPEG 4 o VC 1 achieved best quality in independent studies 2 rounds of DVD Forum tests for HD Oct Dec 02 C T Magazine codec evaluation May 03 DV Magazine evaluation for HD codecs Oct 03 C T Magazine HD codec evaluation May 05 o Most consistent quality in EBU tests Oct 04 dates ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva VC 1 vs H 264 Complexity ITU T o VC 1 decoding is 2x faster than H 264 decoding H 264 3 4x slower than MPEG 2 MP MPEG 4 SP Based on H 264 s own studies VC 1 1 5x slower than MPEG 2 MP MPEG 4 SP Based on empirical data e g testing VC1 WMV 9 vs MPEG 4 SP in PCs 1080p VC 1 software decoding possible on today s PCs DVD companion discs with 720 1080p dates ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva Microsoft Tools ITU T dates o Windows Media Encoder 5 speed settings super real time to best quality Free download o VC 1 Porting Kit RTM Fully aligned with latest SMPTE VC 1 specification Comes with set of conformance test vectors Encoder and Decoder Porting Kit o MPEG 2 Utility Package beta ASF MPEG 2 Transport conversion utilities Encoder utility with direct encapsulation into MPEG 2 Transport RTM scheduled for mid 2005 ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva Conformance Testing Program o Program available for licensees ITU T New tools to facilitate initial selfconformance Microsoft validates the submissions o VC 1 Elementary Stream analyzer tool will be available soon dates ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva VC 1 Platform Support ITU T dates Windows Media platform includes VC 1 and enables integration of all A V devices in networked home ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva Why VC 1 ITU T o Requires less computational power and can be decoded at full 1080i p resolution on today s off the shelf PC o Advanced Profile delivers compression efficiencies far superior to MPEG 2 o Delivers HD content at bit rates as low as 6 8 Mbps o Better visual quality demonstrated in independent tests dates ITU T VICA Workshop 22 23 July 2005 ITU Headquarter Geneva Why VC 1 ITU T o SMPTE VC 1 is nearing standardization and widespread adoption is underway through the implementation of WMV9 o VC 1 is fueling the coming wave of HD content everywhere from next generation DVDs set top boxes PCs and more o VC 1 is being adopted by industry leaders in the broadcast content and wireless industries for new and innovative backend solutions and delivery services
