video capture transfer rate
I need to capture live video feed from a 4MPixel/Frame, 30Frames/sec, 16bits/pixel high resolution camera and for that I need to know what the data transfer rate of the video capture card should be. Multiplying 4*30*16 becomes 1.9Gbits/sec. Does this mean that I should use a 1.9Gbits/sec capture card? Since 1 Byte=8 bits, 1.9Gbits/sec becomes 240MBytes/sec. Capture card transfer rates are specified in MB/sec. I'm not sure whether it's MBytes or MBits. I would appreciate it very much if someone could help me figure out the way to calculate the required capacity of the capture card. Thanks!
