The digital camcorder converts incoming audio and video signals into digital form for recording.
A video signal is comprised of a luminance signal (Y) and color signals (R-Y and B-Y). These signals are
identified and recorded digitally (Digital Component Recording). The A/D (Analog to Digital) converter
samples the Y signal at 13.5 MHz, and R-Y and B-Y at 3.375 MHz, and changes them to an 8-bit quantum
signal.
Sound sarnl)led at 48 kHz is changed to a 16-bit quantum signal, and sound sampled at ;2 kHz is converted to
a 12-bit signal.
