Hey gang,

I ran into an issue with two of my MXP990s (one running f8.2 and the other running f7.0) where the camera image from the MXP990 appears in 16:9 letterbox format when connected to any Polycom VSX8000.  I conferenced with Polycom and tested with their HDX9004, HDX4000, VSX7000e, and another MXP880 for a control.  The HDX9004 and the MXP880 display the camera image from my MXP990 in 4:3 but the Polycom VSX8000 and VSX7000e displayed the MXP990 camera image in 16:9.

Polycom says that Tandberg MXP units (regardless of a composite video camera or HD as the input type), transmit all camera video in a 16:9 aspect ratio. 

Tandberg, I need a way to control the output aspect ratio coming from the MXP990.  I've tried all settings on the Polycom units and they won't display any MXP unit's camera image in 4:3, but they will 4:3 any camera image from a Tandberg Classic codec.

Any xConfig commands that we don't know about?

Any ideas?

Thanks.

Collin

Hi Colin,

This forum is for integrators and developers only. The topics should be around integration and development of solutions with TANDBERG equipment only. This is NOT a product support channel.

If you have support related questions please contact your TANDBERG support representative. Your TANDBERG account manager or sales engineer will be happy to answer your question or help you connect with these specialists.

Best regards
Roger

Hi Roger,

Thanks for informing me of the obvious.  I'm a Tandberg integrator, and partner. 

Here's a R&D question.  Why  does the MXP880/990 send its camera image encoded in a 16:9 format (after an upgrade to f8)?

Hi Collin,

I'm considering this as support  as you will need to provide the logs, call status etc for us to be able to provide an answer to this question. I can see from the original posting that it works fine towards another TANDBERG unit. However, the TANDBERG 880/990 should not send a wide format as it is using a 4/3 camera. Normally it should send a CIF image at lower frame rates, or a 448p image at higher bandwidths. These are 4/3 formats.

Best regards
Roger

Roger,

I worked with KBZ during troubleshooting and confirmed with their Tech Support Manager that the MXP990 is sending its camera feed in 16:9.  I'm headed back out to the client site to test with different firmware versions.  The client tested with another MXP990 running f7.0 and that codec transmitted its camera feed in 4:3, so I believe that I ran into an issue with f8.2.  Nonetheless, I've got to go double-check my client's findings.

KBZ sent in a feature request for future firmware releases to Tandberg.  At this point, all I can do is give you guys the best info possible.  I'll contact KBZ to get their call log number.

Thanks for the help

Collin

Hi Colin,

No worries :=) The best thing would be to open up a ticket on this so we can trace it further and get all logs necessary.

Hi Roger,

Since KBZ holds the maintenace contract on all of our Tandberg codecs, Tandberg's call center folks won't open a ticket for me.  Instead they just tell me to call KBZ.

Luckily, I can log into both Tandberg and Polycom web interfaces and screen capture the call status from each codec.  I'll attach the image files to this blog once I can get back onsite.

Hi Roger,

I resolved the MXP990 camera image appearing in 16:9 on the VSX8000 (running Polycom software 9.0.5.2) by downgrading the MXP990 from f8.2 to f7.4. I took screen shots (but I don't think they will help) of the call status from each test.  Please let me know and I'll email them to you.

Please let Tandberg R&D know that we're baffled why version f8 sends the MXP990 camera image in 16:9 format.

Thanks!

Collin

Hi Colin,

I believe this issue is related to the Natural Video (ICIF) setting. Turning this off should also resolve the problem. We will look into why this happens in F8.x.

Best regards

Hi Roger,

Thanks for the tip.  KBZ had the same idea a few days ago.  As soon as the client calls me back out to their site, I'll upgrade the unit back up to f8.2 and disable natural video.

Cheers!

Collin
