Standby: Behaviour of the LTC output during stop (tc operating mode)
- no standby, i.e. a LTC with permanently identical data is generated during stop.
S Standby, i.e. the LTC output is muted during stop.
Offset: Time information of the read-out LTC with offset addition
- no offset, i.e. this function is not active.
o The offset is activated, i.e. the pre-set offset is added before adopting the read-out
time. The offset acts upon the tc operating
mode as well as upon the transfer of the
VTR LTC into the LTC(MTD).
Sync: Data transfer only after genlocking to the LTC has been performed (tc operating mode)
- The function is deactivated.
L The function is active, if the generator shall be synchronised to the external LTC
(genlock = LTC). The readout values shall only be adopted by the generator, if the
read-out LTC does not exceed the limits of the frequency tolerance specified for gen-
locking.
3.10.2 OFFSET: Offset Programming for the Time Information
Display and adjustment of a time offset. If the offset function is activated (LTC IN - MODE
menu), the time information of the readout LTC is added to the offset and then made
available for the Jam-Sync application or the VTR LTC. A negative offset is generated by taking
into account the 24-hours carryover, i.e. a value of minus one frame is e.g. calculated by
using an offset of 23:59:59:24 (with frame rate = 25).
Press the enter button to display or change the current setting. The flashing pair of digits can
be changed using the
↑ or ↓ button, the next pair of digits can be selected using the →
button. The range of values 00-23 is for the hours, 00-59 for the minutes and seconds and
00-23/24/29 for the frames, according to the selected frame rate. The frame rate of the
readout LTC should correspond to the frame rate of the generated LTC. Press the enter button
to confirm your choice and to quit the menu.
3.10.3 1 ... 3: Status Data of the Readout LTC
Press the → button to switch different status data of the read-out LTC to the display for test
purposes.
1 Display of hours:minutes:seconds:frames = time information of the readout LTC. The
displayed time does not include any frame compensation or calculated offset.
2 Indication of the binary groups of the readout LTC.
3 Indication of the flag bits of the readout LTC and of an index (Frequ) for the detected
frequency: 0 = stop, 1 = slow, 2 = normal, 3 = fast.
