w448p Resolution
For improved interoperability with Tandberg MXP 990/3000 endpoints, the appropriate System Flag settings
will force the Collaboration Server to send w448p (768x448 pixels) at 25fps as a replacement resolution for
WSD15 (848x480) and SD15 (720x576 pixels).
Guidelines
The w448p resolution is supported:
In CP mode.
At conference line rates of 384kbps and 512kbps.
With H.323, SIP, and ISDN endpoints.
H.323 endpoints must identify themselves as Tandberg MXP during capabilities exchange.
In all Video Layouts.
In 1x1 Layout:
When Video Clarity is Off, the Collaboration Server transmits the same resolution as it
receives.
When Video Clarity is On, the Collaboration Server changes the transmitted resolution to
w448p.
For more information see Video Clarity™.
Resource consumption for the w448p resolution is the same as for SD and WSD resolutions.
The following table lists the video outputs from the Collaboration Server to the Tandberg Endpoints for both
16:9 Aspect Ratio when the w448p resolution is enabled.
Video Output to Tandberg Endpoints- Aspect Ratio 16:9
* It is recommend to set the endpoint to Motion to ensure the transmission of the higher frame rates of 25fps/30fps to
the Collaboration Server.
The following table list the video outputs from the Collaboration Server to the Tandberg Endpoints for 4:3
Aspect Ratio when the w448p resolution is enabled.
