A computer-readable registration medium has a unique computer-readable identifier. Dynamic pictures and still imaged shot using the DV camera may be output via the projector mechanism, so that a user may play back the shot dynamic pictures and still images directly from the DV camera to save the time required for image processing via a computer. A first transfer transistor selectively and electrically connects the first output terminal and a first bit line. The nozzle segment has a narrowing portion at which the first and second members narrow from the opening to increase momentum of the fluid therethrough. The equalizer is particularly suited to in-cabinet and local area network transmissions where feedback circuitry facilitates adaptive training of the equalizer.
