Content

Sharing and receiving Content is supported.
Bandwidth allocated to the Content channel during Content sharing may cause the video resolution to be
decreased as from w448p to w288p.
When Content sharing stops and the full bandwidth becomes available, video resumes at the previous
w448p resolution.
For more information see the
Packet Loss Compensation
If there is Packet Loss in the network and Dynamic Bandwidth Allocation (DBA) is activated, allocating
bandwidth for Lost Packet Recovery, video resolution decreases from w448p to w288p.
When Packet Loss ceases and DBA no longer needs to allocate bandwidth for Lost Packet Recovery, the
full bandwidth becomes available and video resumes at the previous w448p resolution.
For more information see the
Enabling Support of the w448p Resolution
w448p resolution support for Tandberg endpoints requires setting of the following entities:
● Tandberg endpoint
● Collaboration Server flags
● Collaboration Server Conference Profile
