WHDI vs WirelessHD

WirelessHD and WHDI TV were compared.
Tests were performed to evaluate the wireless link stability.
Test conditions were ideal for WirelessHD; the TV was placed 4m from the transmitter in a line of sight conditions.
As can be seen in the following clip, when people cross the line of sight, WirelessHD link becomes very unstable. It is easy to observe that data rate drops significantly, and that the system compensates for this reduction by dropping pixels. In fact, the transmission rate in these conditions allows for transfer of only 25% of the pixels. The resulted artifacts are very annoying to the eye.

I tested the new board from Aminon this week end it is real good. To acheive 1080p60 at such a low phy rate it drops 2/3 video data per frame, kind of downconverting to 1080p20Hz plus the 30% compression per frame already used in previous gen chip. This is only a problem if you want to use it with a panel upconverting at 240Hz where motion gets all blurry and edges flickers. But that's fine customers don't mind video quality especially in medical application.
