Video Resource Requirements and Implications

Lync 2013 SVC clients may not all connect to a VMR with the same stream layout. They are therefore considered H.264 AVC participants and transcoding resources are allocated to them as summarized in the following table.

Support for HD1080p Resolution

The Collaboration Server Hosted deployment supports HD1080p30 video resolution symmetrically for direct calls.

The MS AV MCU Cascade deployment supports HD1080p30 video resolution only if Video Optimized mode is selected and according to the settings of the LYNC_AVMCU_1080p30_ENCODE _RESOLUTION System Flag:

NO (Default) Video streams sent to and received from the MS AV MCU are HD720p30, SD, and CIF.

YES Video streams sent to the MS AV MCU are HD1080p30, SD, CIF. Video streams received from the MS AV MCU are 720p30,SD, and CIF.
