3. Agenda (all in 25mins) Lync 2010 video capability Lync 2013
a standards-based approach Lync 2013 video changes Scalable Video

4. 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

5. 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 later30/07/2012

6. Whats 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
presenters video or photo Presentation View shows meeting content
only Compact View shows just the meeting controls26/07/2012

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

11. 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

allowed bitrate for all combined video streams received, except for
panorama. E.g. if you specify 1500 kbps, then a client can receive
up to 1500TotalReceiveVideoBitRate kbps of video, which may consist
of multiple 180P videoKb streams or a single 540P video stream. :
