The digital video camera converts incoming audio and video signals into digital form for recording.A video signal is composed of a luminance signal (Y) and colour signals (R-Y and B-Y). These signals areidentified and recorded digitally (Digital Component Recording). The A/D (Analog to Digital) convertersamples the Y signal at 13.5 MHz, and R-Y and B-Y at 6.75 MHz, and changes them to an 8-bit quantum signal.Sound sampled at 48 kHz is changed to a 16-bit quantum signal, and sound sampled at 32 kHz is convertedto a 12-bit signal.
NOTE:
The data recorded on a tape is digital, but the output of the this camcorder is analog.
