Agenda (all in 25mins) • Lync 2010 video capability• Lync 2013 a standards-based approach• Lync 2013 video changes• Scalable Video Codec (SVC)• Video interoperability• Changes to video manageability in 2013• Questions30/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 3

First some Lync 2010 videohistory…• Lync Server 2010 AVMCU is limited to H.263 (P2P only) and RTV video codecs• HD 720p is only possible with RTV and point-to-point (not AVMCU)• Lync Server 2010 needs to be enabled for HD – Set-CsMediaConfiguration –Identity Global - MaxVideoRateAllowed Hd720p15M• HD 720p receive requires either dual core (15fps) or quad core (30fps)• HD 720p both send/receive requires quad core• Interoperability with legacy video requires Microsoft SIP signalling capability and RTV video support (3rd party SW or native support)30/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 4

Lync 2013 a standards-basedapproach• Microsoft engaged in Unified Communications Interoperability Forum (UCIF) for standardisation of video, transport and signalling• Lync 2013 H.264 bitstream is likely to confirm to UCIF interoperability spec, removing the need to perform media transcoding for other UCIF compliant H.264 systems• Lync 2013 video specifications disclosed publically• Capability to leverage H.264 hardware-based acceleration• Polycom H.264 SVC technology adopted• More on SVC later…30/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 5

What’s new in Lync 2013conferencing?• H.264 SVC/AVC support• Up to 1080p HD multi-party and point-to-point video• Supporting desktop, mobile, and slate devices (including web)• Up to 5 users continuous presence (most active participants/pinning)• HD photos (delivered only via Exchange 2013)• Face detection and smart framing (demo)• Dynamic layouts – Gallery View shows all participants’ photos or videos – Speaker View shows the meeting content and only the presenter’s video or photo – Presentation View shows meeting content only – Compact View shows just the meeting controls26/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 6

Scalable Video Code (SVC)1. Temporal scalability Layer 0 : 720p 7.5fps Layer 1 : 720p 15fps 7.5 frames Layer 2 : 720p 30fps 7.5 frames 15 frames30/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 8

Scalable Video Code (SVC)2. Spatial scalability Layer 0 : 180p Layer 1 : 360p 180p res. Layer 2 : 720p 180p res. 360p res.30/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 9

Scalable Video Code (SVC)1 + 2 = SVC Lync 2013 Lync 2010 Polycom Slate Client Legacy Video Client Client Legacy Video (H.264 SVC (H.264 AVC (H.264 SVC (RTVideo 720p (RTVideo 720p 720p capable) 720p capable) 1080p capable) capable) capable) The combination of these two processes result in video appropriate to the requesting video endpoint. AVMCU routes/discards video modes that are unsuitable for the client based upon SDP discovery30/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 10

Video Interoperability• SVC Config Mode 0, 1 (Simulcast) – Suggestion is Mode 0 for legacy video (H.264 AVC or RTVideo) – Mode 1 for H.264 SVC• Simultaneous streaming being a requirement for non-transcoding MCU• Lync 2010 and/or legacy video endpoints will result in gallery Source: MSDN 2.2.12.2 Video Source view and high resolution video Request (VSR) being unavailable• Video gateways still necessary to facilitate Microsoft SIP signalling• 3rd party bridges still a requirement for communication with standard SIP, H.323, ISDN, TIP, etc.30/07/2012 Microsoft Unified Communications User Group London (MUCUGL) 11
