PREPARATIONS FOR OPERATION Recording Time Codes in Continuation of Time Codes Recorded on Tape The GY-HD110 also incorporates a time code reader. Therefore, 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. Presetting and Recording of Time Code TC/UB/CLOCK menu screen (FRAME RATE: 60/30) The time codes from the internal time code generator can be recorded at the time of recording scenes. • 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". Framing mode: Drop frame/ Non-drop setting TC/UB/CLOCK menu screen (FRAME RATE: 50/25) To preset the Time Code, make the following settings. „ TC GENE. switch Set to REC or FREE. REC FREE : 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 variations may occur in scene accuracy. : 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 DROP : The time code generator's running method is 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 second is approximately 29.97 frames, but per time code 30 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. 40 PREPARATIONS FOR OPERATION Time code (hour, min, sec, frame) „ Presetting time code data The time code and user's bit data are preset on the TC/UB/ CLOCK menu screen. 1. Display the TC/UB/CLOCK menu screen. Select the TC/UB/CLOCK item on the TOP MENU screen. 2. Set the time code (hours, minutes, seconds, frames). 1Rotate the SHUTTER dial to align the cursor (K) with TC PRESET, and then press the SHUTTER dial. • The first digit of the time code blinks. The blinking digit is the one to be set. 2When the SHUTTER dial is pressed, the blinking digit changes. 3When the SHUTTER dial is rotated, the value of the blinking digit changes. When the SHUTTER dial is rotated upward, the value becomes higher. When rotated downward, the value becomes smaller. 4Repeat the procedure described in 2 and 3 above to set the desired value for all digits. 5After setting the frame digit, press the SHUTTER dial to make EXECUTE blink. The setting values are confirmed when the SHUTTER dial is pressed again. To cancel the setting, select CANCEL and press the SHUTTER dial. 3. When all the digits are set • Press the STATUS button to return to the normal screen or • Rotate the SHUTTER dial to align the cursor (K) with the PAGE BACK item, and then press the SHUTTER dial to return to the TOP MENU screen. „ Presetting user's bit data The user's bit data are preset with the UB PRESET item on the TC/UB/CLOCK menu screen. The method for setting is the same as the method for setting the time code described above. • The user's bit can be specified using numerals or alpha- betic letters from 0 to F for each digit. • To record user's bit data, set the UB REC item to ON. CAUTION It is not possible to set all the digits of the user's bit data to "F". Reading of the data during playback will not be possible for an all-F setting. „ Zero-resetting the Time Code or User's Bit Data This is performed with the TC or UB PRESET item on the TC/ UB/CLOCK menu screen. (Performed separately for the time code and the user's bit data.) 1Rotate the SHUTTER dial to align the cursor (K) with the TC or UB PRESET item, and then press the SHUTTER dial. 2Rotate the SHUTTER dial to select ZERO PRESET as the setting value, and then press the SHUTTER dial. MEMO When a menu screen is not being displayed, you can zero reset the time code data by simultaneously holding down the USER2 button and the STOP button for about 1 second. 41
