I don't completely buy the idea that it is the important one, or even one of the important ones. Have any good studies been done that investigate this alleged difference in perception? Does it make any difference that in a theater the audience watching a film spends a considerable portion of its time in complete darkness, whereas the same is not true for television? What about using a monitor with a long persistence phosphor, so that, unlike film, there is *always* a complete image on the screen? Perhaps we should look at the frame rate and motion question, too. If, despite our persistence of vision, having only part of the image on the screen at any one time makes a difference, might not the the lack of continious movement also make a difference? Might this not even make video superior to film in that the update rate is 1/3 faster and therefore the differences between each frame in a moving scene will be less? > Due to the immense bandwidth required to transmit as much > information as a frame of high-resolution film can store, it is > unlikely that future systems will immitate film.

FM does transmit a signal directly, rather than any difference. Both FM and AM radio modulate a carrier to transmit their signal, an AM transmitter changes the amplitude of the carrier in proportion to the input signal, an FM transmitter changes the frequency of the carrier in proportion to the input signal. cjs -- | "It is actually a feature of UUCP that the map of [log in to unmask] | all systems in the network is not known anywhere."
