Pixelation issues on presentation monitor with CTS 3010 for participants

We have four CTS3010 rooms running ver 1.7.1(4864) P1 and any site connected to our rooms experience a pixelation about every thirty seconds in their presentation monitor/display.  It only appears to those being presented to, and looks like the screen does a full refresh. It does not occur in the presenter's room. This issue occurs when the presentation is not changing, and obviously does this when someone changes a slide, or makes a movement within the document camera view. Presentations to our rooms have this issue as well.

We have the 5 frame per second codec, and are told "that's what it does".

Anyone else seeing this?

We have a Cisco TAC ticket open, but wanted to see if anyone else has seen this behavior with this or previous software revs.

Thanks

Hi Shawn,

Which type of video you displaying? static images or video in motion?

Which projector/display model?

Was it working before and after upgrading to 1.7 is broken?

Let us know

Thanks

They are brand new systems that were provisioned with 1.7, so I have no reference.

We are displaying static images via computers and in-ceiling doc cams.

We have the 40" Cisco (Samsung) LCD TV's in all of our systems.

Hi Shawn,


When using a 5FPS presentation channel we use IDR frames for image refresh/repair. IDR frames vary in size 
and in combination with a 5 frames per second video stream, pixilation/blur will be seen.

The solution here is to use presentation codecs with all four of your 3010 rooms to allow for 30fps
presentation sharing.  With the 30fps option, the codecs do not use IDR frames, so that will greatly enhance
the collaboration experience.

This is not new behavior in 1.7, rather a limitation of your current hardware set-up.

Hope that clarifies.

Interestingly enough, our sales rep did not mention that to us when they sold us the hardware...
