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.
