Known Problematic Equipment with SVSi Systems

While SVSi encoders, decoders and other network accessories typically work out of the box with most input or output devices, some devices are known to cause problems when interacting with an SVSi System.  This list may not be complete, and items are added, removed or updated as issues are resolved and worked on.  If you know of another source or display that is having issues with SVSi devices, please contact our technical support staff to help resolve the issues or to be added to the list..

 

 Manufacturer: Model:  Issue:  Resolution: Updated:
Polycom  8000/9000 series VTC Codecs When the VTC Codec comes out of sleep/hibernation, the codec can periodically have problems re-syncing video with the SVSi decoder. This primarily appears to cause problems with the content input on the codec.

1) Modify settings in the codec to prevent going to sleep between calls.

2) Insert a video scaler between the SVSi decoder and the video codec so that consistent video is maintained, even when no source present, or codec is hibernating.

3) Disable SVSi decoder(s) DVI input port when VTC codec is not in use.  Re-enable prior to initiating next call.

Cisco/Tanberg C40 & C60 Camera Input goes black when HDMI audio disabled Enable HDMI audio on Decoder, but mute audio if needed. 02/17/2014
DirectTV H25MP-700 Cable box sporadically drops digital audio to the SVSi Encoder after an extended period of being powered on or no changes on the unit.   Color changes have also been reported - usually shown with a pink screen.

1) Power cycle the cable box periodically during periods of system inactivity.

2) Use analog audio out of the cable box to the SVSi encoder

3) Change encoder color space from auto to on or off, whichever value makes the image correct during normal operation.  If color changes, issue is source specific.
