WHAT’S NEW IN LYNC 2013 VIDEO?
@StaleHansen @NICconf
Lync 2013 Video Improvements• Collocated
• 4000 concurrent users per pool with 12 Front Ends• 250 within a single conference • 375 per Front End
• Dedicated for large meetings• For 250-1000 concurrent users
@StaleHansen @NICconf
Lync 2013 Video Improvements• Point-to-point
• Up to HD 1080p• 2 CPU cores
• H.264 (up to HD 1080p)• RTVideo (up to HD 720p) or • Panoramic video (up to 1920x288, also available in multi-point)
• Conferences• H.264 (up to 1080p)• RTVideo (up to VGA)• Up to 5 active speakers
@StaleHansen @NICconf
What about mobility?• Lync 2010 Mobile
• No Voice/Video over IP experience
• Windows 8/RT Modern UI• Point-to-point video• Multi-party video (Gallery View)• Leveraging H.264 SVC• H.264 encoding within ARM chipsets
• Lync 2013 Mobile• Point-to-point video• Multi-party video (single active speaker)• Leveraging H.264 SVC• H.264 encoding within ARM chipsets

LYNC ROOM SYSTEM (LRS)
@StaleHansen @NICconf
• Familiar • Native Lync • Windows Embedded
7 Standard
@StaleHansen @NICconf
• Joining the LRS to a domain is optional• Requires manual import of certificates (for example, trusted root).
• Joining to a domain has benefits• Easy certificate import.• Easy management by assigning Active Directory groups and
domain users administrative rights.
• When joining LRS to a domain, pay attention to• GPOs (Group Policy objects) assigned to the OU (organizational unit) - create a separate
OU if possible.• Block Inheritance and No Override can cause unwanted effects - check!• Also settings for auto lockout, power management, additional authentication, access to
local drives, auto start of applications, and so on.
@StaleHansen @NICconf
@StaleHansen @NICconf
LRS and bandwidth• Fullscreen video, 1080p
• 1920x1080 (16:9)• Typical 3200 kbps
• Bigger multiview• Conferencing is the norm

@StaleHansen @NICconf
Pexip and Acano• Interop bridge between Lync and the rest• Support all clients, even webRTC• Support for RTV and SVC• Clients need to join separate MCU
@StaleHansen @NICconf
Application Sharing solved!
@StaleHansen @NICconf
@StaleHansen @NICconf
Pexip/Acano
Transcodes to requested codec With application sharing
@StaleHansen @NICconf
Pexip• Software based• Can be virtualized with Vmware
• Hyper-V on the roadmap
• Own client and room to control meeting

Interoperability “built in” to Lync• Lync P2P video calls to VTC• VTC P2P call to Lync • Lync invites VTC to spontaneous or “Meet
Now” Lync meeting (via Lync AVMCU)• VTC is able to join a scheduled Lync Meeting
via “Join Lync Meeting” invite
