1 OVERVIEW
This manual describes the operation of the 8083XDS-AD Analog and SD-
SDI XDS Encoder.
The Model 8083XDS-AD provides a cost-effective method of encoding
eXtended Data Service (XDS) into Field 2 of the analog and digital video
bitstream. It has been designed to meet the needs of both television
broadcast and post-production facilities.
The following table summarizes the major features of the 8083XDS-AD.

Table 1-1: XDS Encoder Feature Summary
1.1 THE CLOSED CAPTION and XDS SYSTEM
The Closed Caption System provides for the transmission of data on line
21 of the NTSC composite signal, or Line 22 of the PAL composite video
signal. The EIA-608-B standard specifies nine data channels or “streams”
for line 21 data services. In each video field there are two caption streams
and two text streams. Field two also contains the Extended Data Service
(XDS) data stream. These are summarized in the following chart:

8083XDS-AD Analog and SD-SDI XDS Encoder
Page 1-2 Revision 1.0.2 OVERVIEW
Field 1 Field 2
CC1 Primary Synchronous Caption Service CC3 Secondary Synchronous Caption Service
CC2 Special Non-synchronous Use Captions CC4 Special Non-synchronous Use Captions
T1 First Text Service T3 Third Text Service
T2 Second Text Service T4 Fourth Text Service
XDS Extended Data Services
The separate data streams are independent of each other in content.
Within each field, the streams are time-multiplexed. Control codes are
transmitted to announce the transition to a different stream. Home viewers
may generally select which data stream to display with their caption
decoders.
The primary Synchronous Caption Service (CC1) is primary language
captioning data that must be in sync with the sound. The Secondary
Synchronous Caption Service (CC3) is an alternate captioning data
channel in sync with the sound, usually used for a second language.
The special Non-Synchronous channels (CC2, CC4) carry data that is
intended to augment information carried in the program and is not
necessarily in sync with the sound.
The four text services are used to carry general text information that may
not be related to the program content. Text stream T2 is often reserved to
carry URL data for WebTV applications.
Extended Data Service stream contains information about the program
such as program title, length, and V-Chip-compatible program rating
information.

Figure 1-1: Typical Line 21 Closed Caption Signal

8083XDS-AD Analog and SD-SDI XDS Encoder
OVERVIEW Revision 1.0.2 Page 1-3
Figure 1-1 shows the typical waveform of the signal. The line 21 data
signal consists of a 7 cycle sine wave clock burst, a start bit, and two data
characters. Each character consists of seven data bits with odd parity.
The clock rate is 32 times the horizontal line frequency or 503.4 KHz. The
signal amplitude is 50 IRE units peak to peak. There is no setup on the
line when the caption signal is present. When caption data is encoded into
field 2, there must at least be null characters encoded into field 1. The full
specification for the caption data waveform and data content is given in the
EIA-608-B standard.
1.2 FEATURES
1.2.1 Hardware System Features:
• 3 RS-232 serial ports can be configured for direct connection to

1.3 DAYLIGHT SAVING TIME ADJUSTMENT
Daylight Saving Time (DST) was instituted to take advantage of the later
hours of daylight between April and October. In 1966, the U.S. Congress
passed the Uniform Time Act that standardized the length of Daylight
Saving Time. For those parts of the United States that observe Daylight
Saving Time, it begins at 2 a.m. local time on the first Sunday of April.
Time reverts to standard time at 2 a.m. local time on the last Sunday of
October. In the spring clocks spring forward by 1 hour to 3 a.m.; in the fall
clocks fall back by 1 hour to 1 a.m. Arizona, Hawaii and most of Indiana
have chosen not to observe Daylight Saving Time.
People often consider daylight saving time to be an “event” that happens
twice a year, setting their clocks ahead or back by one hour. In reality,
DST is in effect (ON) for six months of the year and not in effect (OFF) for
the other six months, in regions that observe DST.
The Caption Encoders will automatically switch their local time to Daylight
Saving time at 2 a.m. local time on the first Sunday of April, and back to
standard time at 2 a.m. local time on the last Sunday of October. The DST
Observed control allows the user to enable or disable the DST adjustment
of the local encoder time (the DSO flag). For regions that observe Daylight
saving time, the DST Observed setting must be set to On, and for regions
that do not observe Daylight saving time, the DST Observed setting must
be set to Off. Regardless of whether DST is observed in a region, DST will
be In effect between the first Sunday of April and the last Sunday of
October. (The DST flag) The front panel time display shows the status of
the DST and DSO flags as shown in Figure 3-4.
There are two XDS packets defined by EIA-608-B for encoding time and
date information. The Time of Day packet (0701) encodes the UTC time
and contains a flag bit (DST Flag) that is to be set when Daylight Saving
Time is in effect (i.e. between the first Sunday of April and the Last Sunday
of October). The Time of Day packet must be inserted locally at each
affiliate station so that the correct time is encoded when programs are aired
at different times across the network.

OVERVIEW Revision 1.0.2 Page 1-5
The Time Zone packet (0704) encodes the time zone offset from UTC time
and contains a flag bit (DSO Flag) that is to be set when the entire area
served by the signal observes Daylight Saving Time. When the DSO Flag
bit is set to Off, it means that the VCR will ignore the DST Flag bit in the
Time of Day packet. The Time Zone packet must be inserted locally at
each affiliate in order to encode the correct time zone offset for the region.
See application note AN3 at the back of this manual for more information
about encoding time in XDS packets.

1.5 GLOSSARY OF STANDARDS
EIA (Electronic Industries Alliance): An association of trade
associations representing various facets of the electronics industry. Each
of these EIA Sector Associations manages its own standards-setting
programs under EIA, the umbrella organization.
EIA-608-B: This EIA standard serves as a technical guide for those
providing encoding equipment and/or decoding equipment to produce
material with encoded data embedded in Line 21 of the vertical blanking
interval of the NTSC video signal. It is also a usage guide for those who will
produce material using such equipment.
EIA-708-B defines the coding of DTV closed captions (DTVCC) as they
are delivered in an ATSC signal, and also defines the Caption Distribution
Packet (CDP). This structure contains fields that can hold: EIA-608-B data
for use if the video is converted to standard definition analog; DTV captions
for use in an ATSC program; Caption Descriptors; and Time Code. The
CDP is the basic unit of data that is transported through the professional
portion of a DTV plant. As such, it is central to the methods discussed in
this document.

EIA-744-A: The EIA standard that defines the formatting of content
advisory information accommodating either U.S. or Canadian systems, as
well as the movie industry’s MPAA rating system using the vertical blanking
interval. EIA 744-A redefines the XDS Program Rating (content advisory)
packet, 05h, currently contained in EIA-608-B, Current Class.
EIA-746-A: This document is a proposed amendment to EIA-608-A to
insert Internet Uniform Resource. Locators (URLs) within the line-21 data
system using the Text-2 (T-2) service. These URLs may be used by
receiving devices in a variety of ways to associate Internet content with
related television broadcast content.
SMPTE (Society of Motion Picture and Television Engineers): A
professional organization that recommends standards for the film and
television industries.
SMPTE 12M: The SMPTE standard for linear time code.
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 244M: The SMPTE standard for bit parallel digital interface
for composite video signals. SMPTE 244M defines the parameters
required to generate and distribute composite video signals on a parallel
interface.
SMPTE 259M: The SMPTE standard for 525 line serial digital
component and composite interfaces.
SMPTE 269M: This SMPTE standard defines an opto-isolated fault
tally output signal for connecting to user-defined equipment such as
warning indicators.
SMPTE 291M: Defines the method of multiplexing ancillary data such as
audio and captions to 292M and 259M signals.
SMPTE 292M: Defines the serial interface that is used for carriage of
HDTV video signals. It and its standard definition equivalent 259M provide
a standard transport mechanism, not only for the video signal, but also for
digitized audio and data such as captions.
SMPTE 309M: The SMPTE standard for encoding date information
into the user bits of linear time code.
SMPTE 333M: The SMPTE standard for serially interfacing
captioning equipment with ATSC XDS encoders
