Recording Time Codes in
Continuation of Time
Codes Recorded on Tape
The GY-HD250/GY-HD251 also incorporates a time code
reader. Therefore, when this device enters record mode from
record-standby mode, it can read the time code data
recorded on the tape and record time codes in continuation
of the existing data.
The recorded user's bit data are identical to the user's bit
date recorded on tape.
* However, approximately ±1-frame variations may occur in
scene accuracy.
To enable this function, set the time code related switches as
follows before starting recording.
Setting
• Set TCG SOURCE on the TC/UB/CLOCK menu screen to
INTERNAL.
• Set the TC GENE. switch inside the LCD door to REGEN.
• Set TC DUPLI. item on the TC/UB/CLOCK menu screen
to OFF.
MEMO
The time code framing mode automatically becomes the
mode (drop frame or non drop frame) already recorded on
the tape.

Playing Back Time Code

This device features a time code reader. During playback,
the time code or user's bit data recorded on the tape is dis-
played on the LCD screen or viewfinder status screen.
• When the [P /P /TC] switch is set to TC, the playback
B R
time code is output from the [P /TC OUT] terminal (Only in
B
VTR mode).
• When HD/SD-SDI OUT of the VIDEO FORMAT[2/2] menu
screen is set to ON, the playback time code is output from
the [HD/SD-SDI] terminal.
MEMO
• During playback, if a portion of tape without recording
time code runs through, the time code stops running.
Playback continues.
• When a tape with a time code that is longer than two
hours is played on home-use DV equipment, time code
may not be played properly on some models.
