This document discusses improvements to video in Lync 2013, lessons learned from the Lync Room System, and updates on Lync video interoperability. Key points include: Lync 2013 supports up to 1080p video and larger conferences; ensuring proper Group Policy and certificate configuration for Lync Room Systems; and that Pexip and Acano solutions now enable application sharing in interoperability scenarios between Lync and other vendors like Polycom and Cisco.

- 16. Video Cropping Control Copped at client side No cropping for conferences SIP SRTP / RTCP @ @NICconf
- 17. LYNC ROOM SYSTEM (LRS) @ @NICconf
- 18. • Familiar • Native Lync • Windows Embedded 7 Standard @ @NICconf
- 19. • Joining the LRS to a domain is optional • • • • • Requires manual import of certificates (for example, trusted root). Easy certificate import. Easy management by assigning Active Directory groups and domain users administrative rights. Joining to a domain has benefits 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. @ @NICconf
