When translating from 30 Fps TO 25 Fps code, the input code must be in the Drop
Frame format. When translating from 25 Fps to 30 Fps code, the Generator DROP
FRAME mode must be set to DROP FRAME. (See section 3.4.13)
OPERATION
Model 8010TM-IRIG SDI Time Code Master with IRIG Reader Manual
The GEN MODE menu item is used to select the type of information
that is contained in the time and user bits of the generator. When the
8010TM-IRIG is not in the Jam sync mode, the generator Time bits
contain time information entered from the front panel.
8010TM-IRIG is in the continuous Jam Sync mode, the time bits are
slaved to the reader time.
Gmode time data configures the user bits for entering numeric data
entered from the front panel.
Gmode time rtime transfers the active reader's time bits to the
generator user bits. (See section 3.5.1 for information on selecting the
active reader) The U/B TRANSFER LED will be on.
reader time is useful when you want to record new continuous time
code numbers and still retain the original time code numbers for future
reference.
Gmode time rub transfers the reader's user bits to the generator time
bits. (See section 3.5.1 for information on selecting the active reader)
The U/B TRANSFER LED will be on. Transferring the reader user bits
is used when reader time data previously transferred to user bits as
above, or other user bit information must be retained when recording
new code. When used in conjunction with the continuous Jam Sync
mode, both the time and user bits will be transferred to the new tape.
Gmode convert sets the 8010TM-IRIG into a 25
conversion mode useful in standards converter applications. (often
referred to as EBU and SMPTE time codes respectively) In convert
mode incoming time code from the active reader in the input video
standard is converted to time code in the output video standard. The
generator time is compared to the active reader's time. When the two
times disagree by more than the JAM WINDOW parameter, the
Generator time is jammed from the reader time, taking into account the
frame numbering differences of 30 Fps and 25 Fps time code. The
frames run at the normal frame rate of the output video standard. The
JAM LED will come on each time the Generator resynchronizes to the
Reader. A jam sync offset can be set using the method outlined in
section 3.3.4.
