This board is HD-SDI, SD-SDI Video signal output Patten Generator.
I have made this board by FPGA and SDI transmitter.
FPGA Part : Altera CycloneIII(EP3C5E144C8N)
SDI Part : Gennum GS2972
Output Format : 1920x1080x60i , 50i, 24Psf
720x486x59.94i , 720x576x50i
Power A,B : A(USB +5V) , B(+12V Adapter)
This Board have various kinds HD-SDI Patten. ( Push SW-D)
If you push SW-B, this board move Auto Patten rotation.
So SW-A is 1Khz embedded audio On/Off switch.
