Cisco Webex Room Kit Plus Video Jitter and Pixelated

Dear All,

 

We are using the Cisco Webex Room Kit Plus.

Codec : One x CS-Codec-Plus with Multi Site License

Tablet : CS Touch 10 V04
Quad Camera : CS-Quad Cam V01

Whenever we have internal discussion with 3 rooms, the video is 4K at 6000 call rate with no issue.

 

However the issue arises when we host 2 rooms ourselves join with 2 rooms with another vendor site.

The video image will be jittering and heavily pixelated. Sound remains fine though.

We have to decrease the call rate to 1152 to get stable video as one of the site will still get pixelated at 1472.

 

What could be the reasons and how do we calculate the 'bandwidth' to allow 4K and call rate of 6000?

How does the other two participants join the call, is it a B2B scenario where call comes through Expressway ?

Hi Nithin,

 

It's a B2B scenario as in no internet access. 

We lay a LAN line to their premises.

 

My multisite license encoder will do the calling to all 3 participants.

Hi Experts,

How do we calculate the 'bandwidth' to allow 4K and call rate of 6000 for each connected participant?

 

We have intention to upgrade to the Cisco server with unlimited license (LAN only, no internet).

If we have 12 different devices calling in from a few locations, what is the bandwidth needed?
