17 H.264/MPEG-4 4 AVC interpretations Baseline codec used most commonly for video conferencing applications Less highly specified for non critical video applications at high framerates and pixel resolutions

18 Where should the intelligence reside? Modern high definition endpoints are complex and costly devices Desired outcomes for product spec sheets is >1 MP resolution (720p) at lowest achievable bandwidth Capital cost and bandwidth reduction techniques now common Simultaneous H.264 encode and decoding operations requires significant processing power to keep the stream manageable Two methods introduced by low cost manufacturers to achieve this: Reduced Complexity Decoding Operation (RCDO) Vendor usage of Static Macroblock signalling: H.241 MaxStaticMBPS parameter

19 H.264 the latest and greatest Expected visual quality for HD resolution rate Bit p 1080p 0 poor fair good very good H.264/AVC (Advanced d Video Coding) H.264/SVC (Scalable Video Coding) Also - multiple stream decompression codecs - eg Octoshape

20 Beyond H.264 and H.323/SIP Microsoft s s developments: VC-1: informal name of SMPTE 421M video standard Used in HD-DVD, DVD Blu-ray Discs, Windows Media Video 9 On2 Technologies (TrueMotion technologies) Initially developed VP6 - selected for Flash 8 video encoding VP7 now current and is used in Skype P2P video calls Emerging Protocols: XMPP+ extensions - Jingle Defines a way for XMPP clients to exchange rich media Jingle audio is well defined (used in Google talk) - video a WIP
