OPERATION
3.6.1.1. Selecting Normal or Powered LTC Output (LTC1 output only)
OUTPUT
LTC 1 OUTPUT
LTC 1 Power
L1 power off
L1 power on
This menu item controls whether the LTC 1 output available on the 3 pin
XLR connector will be a standard SMPTE 12M signal or whether it will be
modulated to drive Evertz 1200 series clocks operating in slave mode. The
LTC 1 output on the 9 pin D connector does not have the capability of
powering the 1200 series clocks. See section 3.3.6 for status messages
related to the LTC1 Power.
Select
L1 power off for all applications except driving Evertz 1200 series
clocks. The LTC output level is set using the LTC level menu item.
Select
L1 power on for applications where you want to transmit power along
the LTC output to Evertz 1200 series clocks.
3.6.1.2. Setting the LTC Output Rate
"
When the Time Reference is set to LTC In or VITC In then the LTC1 Rate menu item
is ignored and the LTC 1 Rate will be set to match the rate of the incoming LTC or
VITC respectively.
OUTPUT
LTC 1 OUTPUT
LTC 1 Rate
L1 rate 30.00
L1 rate 29.97
L1 rate 29.97 df
L1 rate 25.00
L1 rate 24.00
L1 rate 23.98
This menu item sets the frame rate and counting mode of the LTC 1 output.
When using time code rates that do not run at real time, in order to maintain
a correlation to real time they must be resynchronized to the System time
once per day. The
LTC 1 Jam Time menu item is used to set the time when
the re-synchronization will occur. This time should be chosen so that time
code disruptions will have the least effect in the television plant. (See
section 3.6.1.3)
Select
L1 rate 30.00 to generate time code that counts at 30 frame per
second and has a bit rate of 2400 bits per second. This LTC will run at
exactly real time and is often used for driving master clock systems. This
time code will be asynchronous to video sync pulse outputs in the NTSC-M,
1080i/59.94, and 720p/59.94 video standards.
Select
L1 rate 29.97 to generate time code that counts at 30 frames per
second and has a bit rate of approximately 2397 bits per second. This LTC
will run approximately 86.3 seconds per day slower than real time. This
time code will be synchronous to video sync pulse outputs in the NTSC-M,
1080i/59.94, and 720p/59.94 video standards.
Select
L1 rate 29.97 df to generate time code that counts at a nominal 30
frames per second using the SMPTE Drop Frame counting sequence and
has a bit rate of approximately 2397 bits per second. This LTC will run
approximately 2.6 frames per day faster than real time. This time code will
be synchronous to video sync pulse outputs in the NTSC-M, 1080i/59.94,
and 720p/59.94 video standards.
