ABOUT DV77

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 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 sampled at 48 kHz is changed to a 16-bit quantum signal, and sound sampled at 32 kHz is converted to a 12-bit signal.

NOTE:

The data recorded on a tape is digital, but the output of the GR-DVM1 is analog.
