I haven’t found this requirements anywhere so this confused me.
You are right:
640x480 = 307’200 pixel
60 Hz => 18’432’000 pixel/s
32 bit/pixel => 589’824’000 bit/s = 589 Mbps
320x240 = 76’800 pixel
120 Hz => 9’216’000 pixel/s
32 bit/pixel => 294’912’000 bit/s = 294 Mbps
Audio: 16bit
48 kHz => 768’000 bit/s = 0.768 Mbps
Minimum TOT:
294.768 Mbps minimum
USB1.1 is 12 Mbps “Full-Bandwidth” (effective throughput up to ? Mbps)
USB2.0 is 480 Mbps (effective throughput up to 280 Mbps) now called “Hi-Speed”
I’m not sure but the 1.1 throughput can be estimated as 7 Mbps,
so can work only lowering the bit/pixel color dept, AND the frame speed, no audio.
For example:
12 Hz => 921’600 pixel/s
8 bit/pixel => 7’372’800 bit/s = 7.3 Mbps
What is the color dept in bit/pixel of the PS3E? I cannot find nowhere on specifications.
Are there some HW image compression inside the camera?
