a standard monochrome television picture is sampled over a grid of 512 × 480 elements called pixels. Eight bits are required to represent 256 shades of the gray display. To display motion, 30 frames are sampled per second; thus, it requires about 59 Mb/s (512 × 480 × 8 × 30 = 58,982,400). Color transmission requires even higher bandwidth (on the order of 90 Mb/s).
