Model 8010TM-IRIG SDI Time Code Master with IRIG Reader Manual
OVERVIEW Revision 1.4.1 Page 1-1
1. OVERVIEW
The 8010TM-IRIG SDI Time Code Master is a full function time code reader/generator system for serial
digital video. The 8010TM-IRIG is a combination generator for SMPTE Linear Time Code (LTC) and
Digital Vertical Interval Time Code (D-VITC), reader for IRIG-B code and D-VITC (standard SMPTE
time code and special IRIG encoded VITC), and contains a high resolution character inserter which can
be burn the generator or reader numbers directly into the digital program output as well as an optional
analog monitoring output.
The 8010TM-IRIG reads IRIG-B code commonly in use within the United States government agencies
and supporting private industries and provides a display of days, hours, minutes, seconds and
milliseconds in the character inserter. This IRIG information is inserted into a special line of vertical
interval time code which is protected by a unique cyclic redundancy checkword (CRC) so that it is not
confused with standard SMPTE 12M D-VITC by tape recorders and other devices. This special D-VITC
can be decoded by the 8010TM-IRIG’s D-VITC reader to allow you to encode the IRIG information onto
a ‘clean’ video tape and then display the IRIG information later on playback.
The 8010TM-IRIG SMPTE Time code generator can also be slaved to incoming IRIG code. The
millisecond count will be converted to the closest frame number and can also be stored in the generator
user bits along with the IRIG day of the year. In the continuous jam sync mode, the generator is slaved
to the reader, and will follow code any discontinuities of the reader. The generator may also be
momentarily synchronized to the reader, and then it continues to increment normally regardless of the
reader code. Momentary jam is the recommended mode when synchronizing to IRIG-B sources so that
the resulting SMPTE time code does not contain discontinuities due to the different time bases of 29.97
frame per second video and real time of the IRIG code. In NTSC related video systems, the SMPTE
generator should be operated in the Drop Frame counting mode when trying to synchronize the SMPTE
generator to IRIG.
The 8010TM-IRIG will accept 525 or 625 line component digital video. The 8010TM-IRIG’s SMPTE
time code generator can be preset to lock to the digital program video either by simple frame locking, or
where necessary it will colour lock to an analog Colour Reference in accordance with the 4 field NTSC
or 8 field PAL colour sequence.
In NTSC related colour systems operation, with a frame rate of 29.97002618 Hz where the time of day
is used for indexing, the generator may be operated in the drop frame mode. Special indicators in the
front panel display and in the character inserter indicate that the unit is operating in the drop frame
format.
Both the generator and reader are capable of working with the unassigned user bits. Several modes of
operation are possible. The generator may be preset to insert hexadecimal values for each group in
the generated code, and the reader will read hexadecimal values for each binary group. In addition,
the user may select the transfer of either reader time or reader user bits into the generator user bits,
thus, allowing pre-edit frame addresses to be preserved when new continuous time code is laid down.
The high-resolution character inserter provides six independently positionable windows to show time
and user bits for the generator and readers simultaneously. When the IRIG or VITC readers are
operating in the IRIG DAY mode, there are two independently positionable windows for each reader to
show the IRIG time to millisecond precision and the IRIG day respectively. Three character sizes and
the choice of white or black characters with or without contrasting background mask are selected from
the front panel.

OVERVIEW Revision 1.4.1 Page 1-3
ANALOG: An adjective describing any signal that varies continuously as opposed to a digital signal
that contains discrete levels representing digits 0 and 1.
A-TO D CONVERTER (ANALOG-TO-DIGITAL): A circuit that uses digital sampling to convert an
analog signal into a digital representation of that signal.
BIT: A binary representation of 0 or 1. One of the quantized levels of a pixel.
BIT PARALLEL: Byte-wise transmission of digital video down a multi-conductor cable where
each pair of wires carries a single bit. This standard is covered under SMPTE 125M,
EBU 3267-E and CCIR 656.
BIT SERIAL: Bit-wise transmission of digital video down a single conductor such as coaxial cable.
May also be sent through fiber optics. This standard is covered under SMPTE 259M
and CCIR 656.
BIT STREAM:A continuous series of bits transmitted on a line.
BNC: Abbreviation of "baby N connector". A cable connector used extensively in television
systems.
BYTE: A complete set of quantized levels containing all the bits. Bytes consisting of 8 to 10 bits
per sample are typical in digital video systems.
CABLE EQUALIZATION: The process of altering the frequency response of a video amplifier to
compensate for high frequency losses in coaxial cable.
CCIR: (International Radio Consultative Committee) An international standards committee. (This
organization is now known as ITU.)
CCIR-601: (This document now known as ITU-R601). An international standard for component
digital television from which was derived SMPTE 125M and EBU 3246-E standards.
CCIR-601 defines the sampling systems, matrix values and filter characteristics for both
Y, B-Y, R-Y and RGB component digital television signals.
CCIR-656: (This document now known as ITU-R656). The physical parallel and serial interconnect
scheme for CCIR-601. CCIR-656 defines the parallel connector pinouts as well as the
blanking, sync and multiplexing schemes used in both parallel and serial interfaces. It
reflects definitions found in EBU Tech 3267 (for 625 line systems) and SMPTE 125M
(parallel 525 line systems) and SMPTE 259M (serial 525 line systems).
CLIFF EFFECT: (also referred to as the ‘digital cliff’) This is a phenomenon found in digital
video systems that describes the sudden deterioration of picture quality due to excessive
bit errors, often caused by excessive cable lengths. The digital signal will be perfect
even though one of its signal parameters is approaching or passing the specified limits.
At a given moment however, the parameter will reach a point where the data can no
longer be interpreted correctly, and the picture will be totally unrecognizable.

COMPONENT ANALOG:The non-encoded output of a camera, video tape recorder, etc., consisting of
the three primary colour signals: red, green, and blue (RGB) that together convey all
necessary picture information. In some component video formats these three
components have been translated into a luminance signal and two colour difference
signals, for example Y, B-Y, R-Y.
COMPONENT DIGITAL: A digital representation of a component analog signal set, most often Y, B-Y,
R-Y. The encoding parameters are specified by CCIR-601. CCIR-656 and SMPTE
125M specify the parallel interface.
COMPOSITE ANALOG: An encoded video signal such as NTSC or PAL video, that includes
horizontal and vertical synchronizing information.
COMPOSITE DIGITAL: A digitally encoded video signal, such as NTSC or PAL video that includes
horizontal and vertical synchronizing information.

signal. This is a revision of the earlier EBU Tech 3246-E standard, which was in turn
derived from CCIR-601.
EDH Error Detection and Handling (EDH) is defined in SMPTE RP-165 as a method of
determining when bit errors have occurred along the digital video path. According to
RP-165, two error detection checkwords are used, one for active picture samples, and
the other on a full field of samples. Three sets of flags are used to convey information
regarding detected errors, to facilitate identification of faulty equipment or cabling. One
set of flags is associated with each checkword, and the third is used to evaluate ancillary
data integrity. The checkwords and flags are combined into a special error detection
data packet that is included as ancillary data in the serial digital signal.
EMBEDDED AUDIO: Digital audio is multiplexed onto a serial digital video data stream.

format there are both pulse width modulated and sine wave amplitude modulated
formats supported with many different variations. For the purpose of this manual the use
of the term IRIG B shall refer only to the B122 (modulated sine wave 1 kHz carrier BCD)
and B002 (Pulse width modulated BCD) formats within this standard.
ITU: The United Nations regulatory body governing all forms of communications. ITU-R
(previously CCIR) regulates the radio frequency spectrum, while ITU-T (previously
CCITT) deals with the telecommunications standards.
ITU-R601: See CCIR601
PIXEL: The smallest distinguishable and resolvable area in a video image. A single point on the
screen. In digital video, a single sample of the picture. Derived from the words picture
element.
RESOLUTION: The number of bits (four, eight, ten, etc.) determines the resolution of the
signal. Eight bits is the minimum resolution for broadcast television signals.
4 bits = a resolution of 1 in 16.
8 bits = a resolution of 1 in 256.
10 bits = a resolution of 1 in 1024.
SERIAL DIGITAL: Digital information that is transmitted in serial form. Often used informally to
refer to serial digital television signals.
SMPTE (Society of Motion Picture and Television Engineers): A professional organization that
recommends standards for the film and television industries.
SMPTE 125M: The SMPTE standard for bit parallel digital interface for component video
signals. SMPTE 125M defines the parameters required to generate and distribute
component video signals on a parallel interface.
SMPTE 259M: The SMPTE standard for 525 line serial digital component and composite
interfaces.
TRS: Timing reference signals used in composite digital systems. (It is four words long).
TRS-ID: Abbreviation for "Timing Reference Signal Identification". A reference signal used to
maintain timing in composite digital systems. (It is four words long.)

4:2:2: A commonly used term for a component digital video format. The details of the format
are specified in the CCIR-601 standard. The numerals 4:2:2 denote the ratio of the
sampling frequencies of the luminance channel to the two colour difference channels.
For every four luminance samples, there are two samples of each colour difference
channel.
