CLDTCD12
The CLDTCD12 is a precision, multi-featured time code driven digital time display. The CLDTCD12
decodes VITC, IRIG-B and SMPTE linear/longitudinal time code formats to function as a clock.
VITC
Vertical Interval Time Code (VITC) is a form of SMPTE time code embedded as a pair of black-and-
white bars in a video signal. These lines are typically inserted into the vertical blanking interval of
the video signal. There can be more than one VITC pair in a single frame of video: this can be used
to encode extra data that will not fit in a standard time code frame.
VITC contains the same payload as SMPTE linear time code frame embedded in a new frame
structure with extra synchronization bits and an error-detection checksum. The VITC code is
always repeated on two adjacent video lines, one in each field. This internal redundancy is
exploited by VITC readers, in addition to the standard time code "flywheel" algorithm.
A video frame may contain more than one VITC code if necessary, recorded on different line-pairs.
This is often used in production, where different entities may want to encode different sets of
time-code metadata on the same tape.

IRIG-B
Defined by the Range Commanders Council, U.S. Army White Sands Missile Range. The format
is used by military, government, power industry and many other commercial and industrial
applications. The CLDTCD12 decodes IRIG-B in both a 1 kHz modulated (IRIG-B1) and un-
modulated/pulse width coded/DC level shifted (IRIG-B0) format. All formats of IRIG-B time
code decoded by the CLDTCD12 use the time of year information BCD (Binary Coded
Decimal). All formats of IRIG-B time code decoded by the CLDTCD12 also use the extended
year/date and time zone information in the control functions as defined by the IEEE 1344
specification. SBS (Straight Binary Seconds) information is not decoded. Manchester
format/encoding is not supported.
The CLDTCD12 can be configured for world-wide time zone offset and automatic DST (Daylight
Saving Time) adjustment and allows for reliable, accurate and maintenance free operation. Use of
the automatic DST feature requires that the clock be enabled to accept the time code date
encoding, using the USB port and WinDiscovery software application. The time code source must
provide date encoding in the control bits/fields to the Masterclock/Leitch date encoding standard
for SMPTE or the IEEE-1344 year encoding for IRIG-B.
SMPTE
Society of Motion Picture and Television Engineers format is available in frame rates of 24, 25, and
30 frames second. The CLDTCD12 time code clock supports all three formats. All formats of SMPTE
time code decoded by the CLDTCD12 use the full date information in the user bits as defined by
Leitch, Inc.
The CLDTCD12 does not support decoding of SMPTE drop-frame, reverse running, NTSC,
color frame, blackburst or other video time code formats and synchronization options.
Please refer to the “Specifications” section of this document for additional details.

Time Code Settings
To use the automatic DST adjustments requires that date/year encoding is enabled.
This product contains an automatic detection and gain control circuit for the incoming SMPTE
30/25/24 fps longitudinal/linear time code or for IRIG-B(0) pulse width modulated or IRIG-B(1)
amplitude modulated time code.
To support common SMPTE/IRIG-B standard time codes without date/year encoding to the
aforementioned standards, an option of ignoring the date information encoded in the time code is
provided.
Display Properties
The settings on this window control how the clock displays time, date and level of brightness.
Display Properties configurations will be applied after you click [OK] and then click
[Apply] from the main window.
Set Date Time
The [Set Date Time] feature lets you manually set the time and date for the clock. This may be
most useful for lab situations as the clock keeps time via its internal precision oscillator and
real-time clock when time code is not present. The time can either be set to the time of the
Windows PC or a manual time and date can be entered.
Practical use of this feature requires the clock to be removed from the time code
source.
When the clock has access to a valid time code source, information obtained via time
code will immediately overwrite any manually established time/date.
