Issue Description
The picture of a branch conference site has the rolling disturb every 10 minutes, and the frequency is more and more high recently.
Alarm Information
NONE
Handling Process
Mail the image processing broad and the codec broad to the client, replace them, the problem as old. Remove the cause in the part of image processing. To verifier the TV, connect the video directly with the TV and the display is normal. The grounding cable of the power source has no problem, so the problem maybe in the terminal motherboard. Send our engineer to the locale, found out the client TV has the closed circuit television cable, remove the cable, problem solved.
Root Cause
The signals in the closed circuit television cable are very complex, so maybe they will import the disturbs from the other power source and the grounding cable system in the shield layer
