PREPARATIONS FOR OPERATION

Recording Time Codes in Continuation of Time Codes Recorded on Tape

1. LCD/VF [2/3] menu screen

The GY-HD100 records SMPTE-standard (NTSC) or EBU- standard (PAL) time codes and user’s bits. In the play mode or the record mode, the reproduced time codes or user’s bits are shown on the LCD monitor or in the viewfinder.

•Time code data cannot be output through the unit’s con- nectors.

The time codes or user’s bits can be shown on the LCD mon- itor or in the viewfinder during playback and recording as fol- lows. (Status screen)

The GY-HD100 also incorporates a time code reader. There- fore, when the unit 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 data 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 the TC GENE. switch inside the LCD door to REGEN.

MEMO

The time code framing mode automatically becomes the mode (drop frame or non drop frame) already recorded on the tape.

„Setting

1.Set the TC/UB item on the LCD/VF [2/3] menu screen to ON.

•Time codes or user’s bit data are displayed on the STA- TUS screen.

2.Whether time codes or user’s bit data should be displayed is selected with the TC DISPLAY switch inside the LCD door.

Presetting and Recording of Time Code

TC/UB/CLOCK menu screen	The time codes from the internal time code generator can be
	recorded at the time of recording scenes.
(FRAME RATE: 60/30)
	• The TC/UB/CLOCK menu screen differs depending on
	whether the FRAME RATE item on the VIDEO FORMAT
	menu screen is “60/30” or “50/25”.

STATUS 1 screen

TC	: Time codes are displayed.
UB	: User’s bit data is displayed.

„Time code input entered the IEEE1394

connector (GY-HD100U/GY-HD101E only)

Pressing the STOP button for 1 second in the EJECT or stop mode displays the DV input time code data or user’s bit data from the IEEE1394 connector on the STATUS screen.

DTCG : The time code data from the IEEE1394 connector

DUBG : The user’s bit data from the IEEE1394 connector

To return to display of the original time code or user’s bit, press the STOP button. (Display of the normal time code or user’s bit is also restored by performing VTR opera- tion.)

MEMO

•To record DV input time cord and user’s bit from the IEEE1394 connector, set the TC DUPLI. [DV] item on the TC/UB/CLOCK menu screen to ON.

X See page 74.

•To maintain the continuity of time code data, use with the TC GENE. switch set to REGEN mode when recording DV input signal from the IEEE1394 connector.

•There is no timecode display for HDV input.

CAUTION

Framing mode:

Drop frame/

(FRAME RATE: 50/25)

To preset the Time Code, make the following settings.

„TC GENE. switch Set to REC or FREE.

REC	: The data preset in the time code generator
	runs only during recording.
	Use this setting if it is necessary to record
	continual time codes across different scenes.
	* However, approximately ±1-frame varia-
	tions may occur in scene accuracy.
FREE	: The time code starts to run from the time it is
	preset in the time code generator.

„TC/UB/CLOCK menu screen (FRAME RATE: 60/30)

Use the DROP/NON DROP item to select the framing mode for the time code generator.

DROP	: The time code generator’s running method is
	set the drop frame mode.
	Use this setting when placing emphasis on
	the recording time.
NON	: The time code generator’s running method is
DROP	set to the non drop frame mode.
	Use this setting when placing emphasis on
	the number of frames.

MEMO

Drop frame/Non-drop frame mode

In the NTSC system, the actual number of frames per 1 sec- ond is approximately 29.97 frames, but per time code 30

A time code with a duration of more than 2 hours may not be displayed correctly by DV components for general con- sumer use, as some of these lack the capability to display longer time codes.

frames are processed. To compensate for this difference, the mode called “drop mode” drops frame 00 and 01 for every minute not divisible by 10.

The “non-drop frame mode” is when no frames are dropped and the actual time shift neglected.

„TC/UB/CLOCK menu screen (FRAME RATE: 50/25) Whether or not user’s bit data should be recorded can be selected with the UB REC item on the TC/UB/CLOCK menu screen.
