7-14 Analog/Digital Signal Conversion

This function can be used as an A/D conversion function for inputting an analog AV signal from an analog device to a PC.

7-14-1 A/D Signal Conversion Pocedure

(1) Connect the output terminal of the analog device with the analog terminal of the camcorder using STV-250N (or using S-1 50 if
necessary). Also connect the DV terminal of the camcorder with the DV terminal on the PC using CV-250F or CV-1 50F.
(2) Move the camcorder's power switch to [VCR] and move the Tape/Card switch to "Tape", setting the operating mode to Stop mode
without inserting a tape.
(3) Select this function (A/D signal conversion) from the VCR setting item on the menu. Specifically, set "AV input → DV output" to
"ON".
(4) Open the motion video acquisition software program on the PC and output the analog AV signal from the analog device.
The analog AV signal from the analog device is converted by the camcorder to a digital signal (DV signal). The PC can then acquire
the video and audio from the analog device, making it possible to record motion video and still images as needed.

7-14-2 CGMS

• A/D signal conversion for both DV input and analog input is only possible when there is no copy protection (CGMS = 00).
• If a value other than "00" is detected for CGMS, then the A/D signal conversion function is closed, the LCD panel/CVF changes
to blue background, the audio output is muted, and the following warning message is displayed: "COPYRIGHT PROTECTED
DUBBING RESTRICTED".
