It all depends upon what you are trying to switch? In this case, an HDMI signal. At this point all bets are off. I could manually plug it between sources or destinations and the outcome would depend entirely upon the mood that the particular source or destination was in at the time of connection. Anyone in the industry knows that HDMI is awful, HDCP is even worse, so you need to demonstrate a more reliable transport stream in order for customers to be able to compare the switching performance of your product.
To bad the LAN jack on Crestron RMC boxes don't work as good as it switches video. It's basically useless. Also, would like to see this test with the dual fiber DM system. Good luck getting that to work reliable. Constantly had to reboot those RMC boxes.
This is stupid. Video signals aren't synced and they're switching between different resolutions. And, when they used scalers, they apparently didn't feel like syncing (genlocking) the scalers and the switch. No one should design a system like Crestron has in this video. This is amateur hour Audio Visual.
