The digital camcorder converts incoming audio and video signals into digital form for recording.<br />
A video signal is composed of a luminance signal (Y) and colour signals (R-Y and B-Y). These signals are<br />
identified and recorded digitally (Digital Component Recording). The A/D (Analogue to Digital) converter<br />
samples 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<br />
signal.<br />
Sound sampled at 48 kHz is changed to a 16-bit quantum signal, and sound sampled at 32 kHz is converted to<br />
a 12-bit signal.<br />
NOTE:<br />
The data recorded on a tape is digital, but the output of this camcorder is analogue.<br />

1 Sub-Code Area<br />
The Time Code and Date/Time data are<br />
written here, separate from the video data.<br />
This enables you to display the date and<br />
time during playback, even if they weren’t<br />
displayed while recording.<br />
2 Video Area<br />
The digital video signal is recorded here.<br />
3 Audio Area<br />
The digital audio signal is recorded here.<br />
4 ITI (Insert and Tracking<br />
Information) Area<br />
Insert editing and post-recording editing<br />
tracking signals are recorded here.
