GENERAL
Reference Timing
H: 0 to max samples
This menu item allows you to set the horizontal timing of the output video
with respect to the genlock reference input. Setting this control to 0 keeps
the output video in time with the genlock reference.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video with respect to
the genlock video, set the control to the maximum number of samples per
line for the output video standard minus the number of samples that you
wish to advance the output video. (E.g. for 1080i/59.94 output video the
total number of samples per line is 2200, so to advance the output video 5
samples set the value to 2195.)
GENERAL
Reference Timing
V: 0 to max lines
This menu item allows you to set the vertical timing of the output video with
respect to the genlock reference input. Setting this control to 0 keeps the
output video in time with the genlock reference.
Increasing the value will delay the output video in one-line increments. In
order to advance the vertical timing of the output video with respect to the
genlock video, set the control to the maximum number of samples per line
for the output video standard minus the number of samples that you wish to
advance the output video. (E.g. for 1080i/59.94 output video the total
number of samples per line is 2200, so to advance the output video 5
samples set the value to 2195.)
4.6.3. Firmware Version and Evoking an Upgrade
GENERAL
Update Code
7725DSK-LG
x.xx build xxx
boot 1.01
yes-upgrade now
no-don’t upgrade
This menu will inform the user of the product name, firmware, and boot
firmware.
It will also give the user an option if they would like to upgrade the firmware
in the unit.
(Note: Firmware upgrades can be performed through software provided in
the Keyer Tool Kit CD.)
4.6.4. Configuring the Real Time Clock
The 7725DSK-LG contains a real time clock that is used to drive the clock display logos that can be
placed on the screen. This battery backed up real time clock (known as RTC) free runs on an internal
oscillator and can be set from the front panel. When the 7725DSK-LG is powered up with a valid
video input, a separate clock (known as the UTC) is initialized from the RTC and maintains Universal
Coordinated time (UTC) accurately from the video input so that it will not drift. The 7725DSK-LG
automatically updates the RTC clock from the UTC clock to minimize long term time drift. In order to
keep the UTC clock in sync with your house master time code it should also be locked to incoming
linear time code connected to the LTC IN connector. The UTC clock time is internally maintained as
Universal Coordinated Time (UTC) but can also be adjusted for time zone offsets from UTC and for
daylight saving time, and displayed as local time (Local). The Time Setup sub-menus of the General
setup menu are used to configure the real time clock and display the UTC and Local times.
