Os. Serial. Monitor. ViBook USB Adapter Review: Who Doesn't Want Four Extra Moni. @ScottRose: 1600x1200 (pixels) * 16 (bits/pixel, assumed) x 30 fps (assumed) = 921,600,000 bits/sec This is well above USB 2.0's maximum theoretical bandwidth of 480 Mbits/sec, so they must be using some kind of compression.
If they aren't using compression, dropping to either 8 bits/pixel or 15 fps would halve the bandwidth requirement under 480 Mbits/sec. @waltercrm: it's not sending a video signal or all the pixels every frame. Wireless USB Digital Microscope. DSL information.
