Created by: henry kyburg on 16-09-2010 04:41:51 PM We at University of California San Francisco have C90s integrated into 6 of our most important lecture hall AV systems. We use them mainly for their video switching and scaling abilities.
When routing an input source to an output using frame update commands, the display of another output is interrupted by about 1 second of black.
For example, a presenter's laptop/input 3 (analog) is routed to output 4 (analog) while the camera/input 1 is routed to a video capture device on output 2 (analog). If we change the source for output 2 to the presenter's laptop/input 3, then output 4 is interrupted by 1 second of black, even though we have not changed the input source routed to output 4.
This is a real problem for us, as it keeps technicians from making any routing changes during an event.
Would Tandberg please address this with a software fix?
Could an engineer please respond to acknowledge the issue?
Thank you very much. WE LOVE TANDBERG

This last command cause the video to output 4 to be interrupted by black for about 1.5 seconds.

From then on we are updating the frames .. Thanks, Bret
