Quizplus · Accepted Answer

The bandwidth necessary can be calculated by multiplying the resolution (320 pixels x 240 pixels = 76,800 pixels), the color information per pixel (1 byte = 8 bits), and the frame rate (30 frames per second). This gives 76,800 pixels/frame * 8 bits/pixel * 30 frames/second = 18,432,000 bits per second, or 18.4 Mbps.
