The TDR6 supports both single-channel-per-carrier (SCPC) and
multi-channel-per-carrier (MCPC) operations and can be deployed in either a
point-to-point or point-to-multipoint system.
If the TDR6 has been configured to receive satellite transmissions, it will accept
input from 950 to 2150 MHz at power levels between -65 dBm and -25 dBm. It
can also interface directly with satellite low noise block (LNB) downconverter
input at up to 30 Msps, -25 dBm to -65 dBm. The TDR6 will receive a DVB or
ATSC-compliant input signal, demodulate and decode the signal, and deliver
separate video, audio, and optional data (for example auxiliary data or teletext)
signals.
If the TDR6 has been configured to receive a terrestrial transmission, it will
accept a signal compliant with the acceptable formats described in the option
module section, decode the signal, and deliver separate video, audio, and optional

out the side vents. The minimum air flow clearance required on both sides of the
chassis is three (3) inches and six (6) inches for the rear panel.
Powering on the
TDR6
The rear panel AC power supply interface includes an On/Off (—/0) power switch
and an IEC 320 AC power cord receptacle. The maximum power supply output
for the TDR6 is 200 watts. The typical TDR6 configuration requires 100 watts.
The TDR6 is powered by an auto-sensing, auto-ranging AC switching power
supply. The power supply accepts 100 to 240 VAC at 50 to 60 Hz.
AC Power Cords
The TDR6 shipping kit includes two AC power cords, one for North American
applications, specifically the United States and Canada, and the other for

Depending on the configuration of the LAN, you may need to enter additional
parameters including:
■
Ethernet IP address mask (IP subnet mask)
Ethernet IP gateway
■
For additional information, refer to the MC commands in the chapter on using
a remote unit.
4. From a personal computer connected to the LAN, try to ping the TDR6. At
the command prompt of the personal computer, type
ping <TDR6 IP address> where <TDR6 IP address> is the
previously assigned address.
If a reply is received, the TDR6 is correctly configured.

Issuing Commands
To issue a command from the front panel, perform the following steps:
1. Navigate to the required command or parameter using the Next and Selection
buttons.
2. Select the parameter to be modified. The parameter and its option will begin
to flash.
3. Change the parameter option as required:
■
If the available options appear in a list, scroll through the list using the
Up, Down, or Select buttons.
■
If the option requires a numeric value to be entered, enter the value using
either the Up and Down buttons to increment the value or using the
numeric keypad to type in the value.
4. Issue the command by pressing the Enter key. An asterisk will briefly display
and then disappear when the system is finished processing the request. The
parameter, with its updated value, is then displayed and does not flash.
■
If the Enter button is not pressed, the parameter is not changed.
■
While the TDR6 is reconfiguring the parameter to the new value, the front
panel is temporarily disabled.
The TDR6 configuration files are stored in non-volatile memory. When the TDR6
configuration is changed using the front panel, the changes are automatically
stored in non-volatile memory. The TDR6 automatically restores to the saved
configuration whenever the unit is reset or powered up.

Leaving a Parameter If you have not pressed the Enter button, you can leave a
parameter without modifying it by pressing either the:
■
Previous button which returns you to the previous menu level
Next button which advances you to the next parameter in the list
■
In either situation, the TDR6 will ignore any values entered and return the
parameter to its original setting.
After Pressing the Enter Button If you accidentally issue an incorrect parameter
value to the TDR6, you can correct the error by:
1. Selecting the parameter again using the Selection buttons. The parameter will
begin to flash.
2. Change the parameter option to the correct value.
3. Issue the parameter again by pressing the Enter button

RF Freq
Sets the modulation type.
QPSK, 8PSK, 16QAM
Sets the RF frequency for the QPSK demodulator
950 to 2150MHz above or below your local
oscillator frequency
Note: The IF frequency is the absolute value of the difference
between the RF frequency and the LO frequency. The
demodulator has a valid IF frequency in the range of 2150 MHz
and 950 MHz. Entering values for RF or LO that equal an out of
range IF frequency value will result in an IF value that is either
the maximum or the minimum IF frequency.

Note: The IF frequency is the absolute value of the difference
between the RF frequency and the LO frequency. The
demodulator has a valid IF frequency in the range of 2150 MHz
and 950 MHz. Entering values for RF or LO that equal an out of
range IF frequency value will result in an IF value that is either
the maximum or the minimum IF frequency.
Code Rate
Sym Rate
Sets the Viterbi code rate
■ QPSK: 1/2, 2/3, 3/4, 5/6, or 7/8
■ 8PSK: 2/3, 5/6, 8/9
■ 16QAM: 3/4, 7/8
Sets the demodulator to the frequency of the incoming RF signal. 37500000 sps and 1000000 Sps
Note: If an out-of-range value is entered the TDR6 will not
accept the new value and will revert to the previous value
entered.
To convert symbol rate to data rate, use the
following equation:
Symbol rate x 2 x (188/204) x FEC code rate
Since the data rate is proportional to the symbol rate, entering a
data rate value might fail if the corresponding symbol rate is out
of range.
Converting a symbol rate to data rate and vice versa may be
subject to a small rounding error. The error is less than
0.00001%. It is advisable to use the symbol rate representation
when entering parameters if a conversion error cannot be
tolerated.
In cases where the demodulator is not locking on the carrier, it is
necessary to add an offset to the symbol rate. This compensates
for the symbol rate drift. The range of the offset is between
0.0002% and 0.0006%; in general a value of 0.0004% proves

the transport stream.
Once you have selected a service, the Video Decoder, Audio Decoder, and User Data menus display the PIDs available for the
selected service.
Number
Selects a service from those available in the transport stream.
Once a service is selected, the TDR6 processes that service
until:
Displays a list of available services.
■ Each available service in the transport stream
consists of a program number, a service
name, and a service provider.
■ Another service is selected
or
■ If the transport stream does not contain
service names and providers, only the
program numbers are displayed.
■ The selected service is no longer available in the transport
stream
■ If the transport stream input is not connected,
or if it lacks PSI information, the LCD displays
the message: No services available.
Auto Select
Determines which service, including audio and data services,
that the TDR6 will select when any of the following events occur:
■ The TDR6 power is turned off and then restored, or the unit is
reset
■ The TDR6 loses and then re-establishes lock on the transport
stream
Note: Since the typical SCPC transmission consists of a single
service that includes of a single video/audio pair, the Auto Select
feature was added to simplify the configuration process for
typical SCPC users. When the Auto Select feature is enabled, or
set to On, the decoder automatically selects the service with the
lowest service number first, then selects the video component
with the lowest PID, and finally selects the audio components
with the lowest PIDS for audio A/B.
■ On – when Auto Select is set to On, the TDR6
automatically selects the first available service
in the transport stream.
Note: If you change the Auto Select function to
On after you have selected a service, the
TDR6 will continue to process the service you
selected until one of the events occurs, then
the TDR6 selects the first available service in
the transport stream.
■ Off – when Auto Select function is set to Off,
the TDR6 searches the transport stream for
the last service you manually selected.
If the service is found in the transport stream,
the TDR6 selects the service, and the LCD
displays the program number, service name,
and service provider.
With Auto Select set to Off, the decoder can be configured to
process a particular service, and within that service, to process
selected video and audio services.
If the service is not found in the transport
stream, the LCD displays Service Not
Available, the TDR6 does not select a service,
and no video, audio, or user data will be

Overview of remote communications
Instructions for issuing remote commands
Error messages
Remote command listing
For remote cabling information, refer to Chapter 2.
Any parameter changes made using a remote unit are not automatically stored in flash memory.
When the TDR6 configuration is changed using a remote unit, an operational test should be
performed to verify that the system is operating correctly. Then the new configuration should be
saved by issuing the MC CONFIG SAVE command.
NOTE
If the TDR6 is reset prior to issuing the MC CONFIG SAVE command, any changes made using the
remote unit will not be restored. Instead, the TDR6 restores the last changes saved to flash memory.
Once the configuration is saved using the MC CONFIG SAVE command, the TDR6 automatically
restores the saved settings when the unit is reset or powered up.
Configuring Remote
Software Parameters
Remote Port
After you have cabled the remote unit to the TDR6 remote port, perform the
following steps to establish remote communications:
1. Configure the communications software parameters of your remote unit to
match the following TDR6 remote port factory DVB default settings:
■
■
■
■
Baud rate = 38400 bps
Data bits = 8
Parity = none
Stop bits = 1
Unless you change the remote control settings and save the changes in
non-volatile (flash) memory, the TDR6 restores this list of default
communications settings whenever the TDR6 is reset or powered-up.
2. Press the Enter key on the remote keyboard several times to generate a prompt
(>) on the remote display. Once a prompt appears on the remote display,
successful communication has been established between the TDR6 and the
remote unit.
Once communications are established, the remote port parameters can be
changed to a faster operating speed.
3. If you are unable to generate a prompt on the remote unit, troubleshoot the
remote unit installation and setup:
■
Ensure that the remote unit and the TDR6 are turned on and plugged into
an active AC outlet

package match the factory default setting of the TDR6 remote interface
Verify that the cable between the terminal and the TDR6 is properly
connected
■
■
Power cycle the TDR6 if needed
If the unit still fails to generate a prompt, contact Customer Service.
Ethernet Port
After you have cabled the TDR6 to a network through the TRD6 Ethernet port,
perform the following steps to establish remote communications using Windows
Telnet:
More sophisticated applications are available that allow the user to view commands and responses
more easily.
NOTE
1. At the remote unit, access the remote unit command prompt (>) by selecting
the MS-DOS Prompt.
2. At the > prompt, launch Telnet by typing TELNET. The Telnet window
appears.
3. From the Connect menu, select Remote System. The Remote System dialog
box appears.
4. For Host Name or IP Address, type the TDR6 IP address. For the procedure
used to assign an IP Address, refer to the installation chapter.
5. For Port Type enter 21846 or 0x5556.
Do not select “Telnet.” If you select “Telnet,” the program will attempt to log you into the device
operating system.
NOTE
6. For Terminal Type, accept the default.
7. Click the Connect button. You should now be connected.
8. If connection is not successful, troubleshoot the installation and setup:
■
Ensure that the TDR6 is turned on and plugged into an active AC outlet
■
Verify that the cable between the terminal and the TDR6 is properly
connected
■
■
■
In Telnet, verify that the correct IP address and port type have been
selected
Check with the Information Systems to determine if problems exist with
the LAN
If you need assistance, contact Customer Service.
Remote
Communications
Overview
The TDR6 can be configured, monitored, and controlled from a remote unit. The
remote unit might be an ASCII terminal, a personal computer, or any other remote
unit capable of asynchronous communications. The TDR6 supports ASCII
protocol for remote communications.
Command Types
The remote unit accepts two different types of commands:
■
Execute commands direct the TDR6 to perform a specified action, such as
changing a configuration parameter.

Execute commands consists of a command mnemonic, which is followed by a
space, the command instruction, a space, and the parameter.
mnemonic instruction parameter
Command =
{
MC RS232 BAUD 1200
■
Query commands direct the TDR6 to display the current setting of a specific
parameter or to display current status information.
Query commands consists of a command mnemonic, which is followed by a
space, and the command instruction. Query commands are issued by typing
the command, without a parameter, and pressing Enter. The TDR6 responds
to the query by displaying information on the remote display.
mnemonic
instruction
Command =
{
MC RS232 BAUD
The TDR6 uses the following command mnemonics to group various commands:
■
AD – audio decoder commands
The TDR6 can be configured with up to six separate audio channels based on
the installed option cards. The ports are identified based on the following:
■
■
■
If only a TDEC-6100 option module is installed, analog audio ports A and
B can be configured.
If only a TAUD-6100 option module is installed, digital audio ports A to
D can be configured.
If both option modules are installed, audio ports A, B, C, and D
correspond to the digital audio ports located on the TAUD-6100 board,
while audio ports E and F correspond to the analog audio ports located on
the TDEC-6100 option module.
■
■
DC – decoder services management commands allow you to configure
various decompressor/decoder control operations.
DMD – demodulator commands allow you to configure each of the four LNB
input ports and to display receive signal status information. For DMD
commands, a period must be entered to separate the mnemonic from the
channel designator.
■
■
■
■
demodulator A (DMD.A) — used to configure LNB A
demodulator B (DMD.B) — used to configure LNB B
demodulator C (DMD.C) — used to configure LNB C
demodulator D (DMD.D) — used to configure LNB D
■
■
Fault commands enable you to query faults and clear the fault history.
HD – high-definition video decoder commands allow you to display or set the
HD video operating parameters.

■
MC – enable you to display or set various master controller functions
including the remote control interface, nonvolatile configuration memory,
date and time settings, and network setup.
■
■
PGCA – Tiernan’s conditional access commands allow you to display a
signal’s protection and authorization status.
UD – user data commands
The TDR6 can be configured for two separate user data channels, which are
referred to as user data channel A and user data channel B.
■
UDA channel controls user data channel A.
UDB channel controls user data channel B.
■
■
VD – Video decoder commands allow you to display or set operating
parameters for standard-definition video.
Issuing Remote
Commands
To issue a command from a remote unit, type the command at the remote prompt
(>) with the appropriate parameter, and then press the ENTER key. The TDR6
performs the required function and displays the prompt (>) when it is ready to
accept another command.
The following syntax is used: <command> <parameter>
where
■
<command> consists of its mnemonic and the instruction; ensure that the
command is typed correctly and includes spaces, periods, or underscore (_)
characters as appropriate
■
■
There must be one space between the command and the parameter. A space is
typed by pressing the Space Bar key.
<parameter> is the value pertaining to the command. Parameters can be
numeric or alphanumeric. No spaces should be typed after the parameter;
doing so will result in an error.
For example:
To set the remote port baud rate to 1200 bps, issue the command
MC RS232 BAUD 1200 and press Enter. In this example:
■
■
■
■
The command mnemonic is MC RS232 followed by a space
The command instruction is BAUD followed by a space
The parameter is 1200
■
To query the remote port baud rate, issue the command MC BAUD and press
Enter. The TDR6 responds by displaying the baud rate on the remote unit.
The audio decoder (AD), demodulator (DMD), and user data (UD) commands
contain additional command designators which enable you to configure a specific
port. The command designators, shown on the TDR6 rear panel, are:
■
■
■
ADA through ADF – audio ports A through F
DMD.A through DMD.D – demodulator ports A through D
UDA and UDB – user data ports A and B

This chapter provides information on configuring the TDR6 for initial operation
including:
■
Quick start configuration
■
■
■
Setting the DVB defaults
Selecting a service
Setting the time and date
■
Detailed TDR5 configuration
■
High-level configuration procedure
Configuring the demodulator
■
Configuration changes may be made using the front panel or remote commands.
All TDR6 configuration changes issued from the front panel are automatically
saved to nonvolatile memory.
Unlike front panel operations, TDR6 parameter changes made from a remote unit are not
automatically saved to nonvolatile memory. If configuration changes are made to a TDR6 from a
remote unit, issue the command MC CONFIG SAVE <string> to save the configuration to
nonvolatile memory.
NOTE
Quick Start
Configuration
To set the TDR6 to the default configuration and immediately begin operations,
follow these steps:
1. Set the TDR6 to the appropriate default configuration.
2. Select a service.
3. Set the local date and time.
In the TDR6, both the video decoder and the audio decoder are fully
auto-detecting, which means that the TDR6 automatically sets the video and audio
parameters based on the incoming service signal.
Setting the Default Configuration
To initialize the TDR6 to the DVB-compliant default configuration using the front
panel follow these steps:
1. From the main menu, select Config.

4. Press the Enter button. The TDR6 reconfigures the system to the DVB
defaults.
Initializing . . .
5. When the DVT Receiver/Decoder main menu displays, the TDR6 is set to the
default DVB configuration.
To initialize the TDR6 to the DVB-compliant configuration using a remote unit:
1. Issue the command MC DEFAULT RESTORE DVB.
2. Ensure that the baud rate setting for your remote device communications
package is set to 38400 bps.
If the remote unit is set to communicate with the TDR6 at a baud rate other than 38400 bps, the
remote unit will not be able to communicate with the TDR6 after the defaults have been set. To
resolve this issue, the equivalent parameter in the software settings of the remote unit must be
changed to 38400 bps.
NOTE
However, the remote unit software settings must not be changed before issuing the MC Default
Restore command to the TDR6, as the remote unit will not be able to communicate with the TDR6.
Selecting a Service
The TDR6 automatically selects the first service in the transport stream. You may
need to select another service. To select a service using the front panel:
1. From the Details menu select Service>Number. The LCD displays the current
service.
2. Select the service, which begins to flash.
3. Scroll through the list of services until the required service is displayed.
4. Press the Enter button.
To select a service using the remote unit issue the command DC PROG #,where
#is the number of the required service.

2. Use the keypad to type in the correct date in mm.dd.yyyy format and press
Enter.
3. Press the Next button. The LCD displays the Time menu.
4. Use the keypad to type in the correct time in hh.mm.ss format, separating each
category with a period, and press Enter
To set the date and time using a remote device:
1. To set the date, issue the command MC CLOCK DATE <mm/dd/yyyy>
where <mm/dd/yyyy>is the current month, day, and year.
2. To set the time, issue the command MC CLOCK TIME <hh:mm:ss> where
<hh:mm:ss> is the current time.
Detailed TDR6
Configuration
TDR6 Detailed Configuration Procedure
The following steps are a high-level procedure you should use to make any
required configuration changes.
1. Make a list of your operational requirements.
2. Determine which TDR6 default parameters must be changed by comparing
your requirements to the corresponding DVB-compliant or other default
parameter settings.
3. Write down the parameter values required to meet your operating
requirements and the corresponding front panel or remote commands required
to change those parameters.
4. Configure the TDR6 to the selected default configuration.
5. Configure the TDR6 with any new parameters.
6. Save the configuration.
7. Ensure that the encoder is correctly configured to operate with the TDR6
parameter settings.
Demodulator Configuration
If the TDR6 includes one or more demodulators, you must configure the TDR6
before beginning operations.
This chapter contains basic demodulator configuration information. For additional
technical information regarding demodulator configuration, refer to the QPSK
demodulator appendix.
Required Information
Before you begin to configure a demodulator, you must have the following
information:
■
■
■
■
■
Satellite downlink frequency (RF Freq)
LO frequency (LO Freq)
Transport data rate or transmission symbol rate (Data Rate)
Viterbi code rate (Code Rate)
LNB voltage (LNB Power) required to polarize your LNB to the downlink
signal

Configuring the L-Band Carrier Frequency
The LNB downconverter outputs a DVB-compliant, modulated L-band carrier at
an IF frequency which is input to the demodulator. For proper operation, the input
L-Band carrier frequency must be equal to RF Ð LO where:
■
RF is the carrier frequency at the input to the LNB
LO is the local oscillator frequency within the LNB
■
Note that it is not the absolute values of RF and LO that are important, just the
difference.
You must configure both the RF and LO parameters. If the entered RF or LO
parameters are incorrect, the actual carrier frequency will be different from the
programed carrier frequency.
To determine the difference, if any, query the Offset parameter.
While the TDR6 is acquiring carrier lock, the Offset parameter is not valid. Once
lock has been achieved, the offset parameter provides a valid measure of the
difference between the actual receiver carrier and the calculated receiver carrier.
To achieve carrier lock, the Offset must be less than 2 MHz. For optimum
performance, the Offset parameter should be as close to zero as possible.
To configure the L-band carrier frequency:
1. Check the Offset parameter.
2. Adjust the RF and LO parameters if necessary.
To query the offset using the front panel:
Select Details>Input>Status>Offset.
To adjust the RF and LO parameters using the front panel:
1. When the decoder is locked onto the receive carrier, query the offset
parameter using the front panel Details>Input>Status>Offset menus or the
remote command DMD.x OFFSET.
The Offset parameter must be less than 2 MHz to achieve carrier lock. For
optimum performance, it should be zero.
2. Verify that you have entered the correct LO value. Refer to the LNB
documentation.
3. Adjust the RF parameter, if necessary.
a. Subtract the Offset parameter from the current RF parameter (RF Ð LO).
b. Enter the result as the new RF parameter using the front panel
Details>Input>Config>Demod>RF_x>RF Freq menu or the remote
command DMD.x RF <new value>.
Example: Configuring the Demodulator
This is an example of configuring a TDR6 with a TDEM-6110 option module
installed. Use this example as a guide, substituting your site-specific parameters.
Step 1: In this example, assume that your operations require the following
parameters:
■

Illuminated green
The above conditions do not exist
Current Faults
If the Faults LED is illuminated, the TDR6 has detected a current fault. Current
faults are reported in real time. This means that the Current Faults function
displays only currently existing conditions.
The faults generated depend on the option modules installed in your TDR6.
To determine if any other faults have occurred, review the Fault History Log.
Fault History
The TDR6 maintains a log of all the faults that it detects over a period of time, not
just the current faults. The TDR6 detects a variety of hardware faults as well as
operational faults that are not reported as current faults and that do not illuminate
the Fault LED. These faults are all logged in the fault history.
All faults are stored in volatile memory until the power is turned off or the unit is
reset.
Time Tags
The TDR6 has a battery backed, internal real-time clock. This clock is used to
time tag faults. A time tag enables you to determine when and how often a
particular fault has occurred.

Initialization Self-Test
Function
The TDR6 has several built-in-self-tests. many of these tests are performed
automatically when the unit is powered up or reset. Faults detected when the unit
is powering up are displayed as error messages on the LCD screen.
Other self-tests are performed during real-time operation as the system monitors
the transport stream. Faults detected while the unit is running are indicated by the
LEDs on the front panel.
You can also query the system on the status of faults using the Faults menu.
Troubleshooting the
QPSK Demodulator
This section provides information on troubleshooting the QPSK demodulator in a
TDR6 configured with a TDEM-6110 option module.

Receive Carrier Offset
The Offset value displays the difference, in MHz, between the actual receive
carrier frequency and the frequency determined by subtracting the LO Freq
parameter from the RF Freq parameter ( RF Ð LO ), which have been entered by the
user. To achieve carrier lock, the difference between the two frequencies, as
shown in the Offset, must be less than 2MHz; however, to achieve optimum
performance, the carrier Offset should be as close to zero as possible.
While the TDR6 is trying to lock onto a receive carrier, the Offset value is not
valid. When the TDR6 is locked onto the receive carrier, the Offset displays the
number of MHz you need to adjust the RF Freq in order to achieve optimum
performance.
To achieve optimum performance, the Offset frequency should be as close to 0 as
possible.
For the procedures used to query the offset parameter and to adjust the RF and LO
parameters, refer to the chapter on configuration.
Demodulator Does Not Lock
If the demodulator does not lock, verify that the receive signal E /N and power
b
0
levels are above the minimum DVB limits. If the receive signal E /N and power
b
0
levels are sufficient, confirm that following settings match those of the modulator:
■
■
■
■
RF frequency (RF Freq)
LO frequency (LO Freq)
Transport stream data rate (Data Rate)
Viterbi code rate (Code Rate)
Demodulator Locks Intermittently
If the demodulator locks intermittently, but the decoder does not lock, confirm
that the E /N level is above the minimum DVB limits. If the E /N is sufficient,
b
0
b
0
confirm that the Viterbi code rate is set correctly.
Performance Problems
If performance is low, take the following actions:
■
■
■
Replace the cable from the LNB to the input port on the TDR6.
Check for ground loop potential.
Check the carrier offset parameter. If carrier is off by more than 1.5 Mhz from
the center, then change RF or LO parameters to reduce the carrier offset.
For the procedures used to query the offset parameter and to adjust the RF and
LO parameters, refer to the chapter on configuration.
■
■
Check adjacent channel spectrum to ensure that there is no adjacent channel
interference
Ensure that the bit rate does not exceed the maximum bit rate for a given
transponder bandwidth.
Refer to the QPSK demodulator appendix for a table providing information
related to bit rates versus transponder bandwidth.

Tiernan VBI Data
Transmission
E
Overview
The latest series of Tiernan encoders and decoders can be configured to transmit
various types of Vertical Blanking Interval (VBI) data when it is present in the
input video.
The following decoders and encoders support one or more methods for
transmitting VBI data:
■
TDR6 – software 3.20 or later
■
TE6000A and TE6000 – software V2.21 or later
VBI Basics
A standard NTSC TV signal consists of 525 horizontal lines, referred to as a
frame. Each frame is divided into two fields, each with 262 ½ lines. The first 21
lines of each field are the VBI region; the remaining lines contain the active video
picture.
A standard PAL TV signal consists of 625 horizontal lines, referred to as a frame.
Each frame is divided into two fields, each with 312 ½ lines. The first 22 lines of
each field are the VBI region; the remaining lines contain the active video picture.
For standard NTSC and PAL video encoding, the first 6 lines of the VBI region
contain vertical timing pulses. VBI data is not allowed on these lines, however the
remaining lines in the VBI region are available to carry any type of data.

MPEG and VBI
Originally, the MPEG video compression scheme discarded all VBI information
and included only the compressed, active video portion of the picture for
transmission. This caused all VBI data to be lost when the video was digitally
compressed for transmission using MPEG.
Today, however, enhancements to the original MPEG compression system have
provided two methods for including VBI data in digital-compressed MPEG
streams:
■
The first method is to extract the data from the baseband video input and
insert that data digitally into the transport stream as either a dedicated PES
stream on a dedicated PID, as in DVB-Teletext, or as an extended data field in
the video frame header information as in ATSC-CC.
■
The second method is to shift, or expand, the active video portion of the
picture to include the VBI lines in the compressed picture frame, as in DVB
4:2:2 expanded windows.
For either of these methods to work, it is required that both the encoder and
decoder are:
■
Functionally capable of processing the required video
■
Correctly configured, either manually or via auto-sensing functionality, for
the employed VBI method
All of the VBI schemes described in this document, with the exception of Tiernan
Proprietary Closed Captions, adhere to industry standards and formats, defined
either by ATSC or DVB. Tiernan Radyne ComStream equipment does inter-
operate with all other vendor’s equipment that is found to be compliant with these
industry standards.
Tiernan’s TDR6 decoder can process data contained in the VBI region of a video
signal according to the following methods and standards:
■
Tiernan-CC – A Tiernan proprietary scheme for transmission of Line 21
closed captions included on a composite analog NTSC or component digital
(525) format video signal.
■
DVB 4:2:2 Expanded Windows – DVB standard for transmission of 16 or 32
lines of VBI data included on a composite analog or component digital (SDI)
format video signal. This standard supports both PAL/625 and NTSC/525
format video standards.

Configuring Your
System
This section describes how to configure your system for successful end-to-end
processing of VBI data for each VBI scheme. For a detailed description of the
front panel or remote commands used to implement the various VBI schemes,
refer to the appropriate command sections found in this manual.
Tiernan Proprietary Closed Captions (Tiernan CC)
Using Tiernan proprietary closed captions, two lines of VBI information are
encoded per frame (one per field) at the expense of losing two lines of active
video (one per field). The encoded picture is simply shifted up one line to include
the last line of VBI and to exclude the last line of active video in each field.
Tiernan CC Mode is for NTSC Format Only

Tiernan CC Field for an Encoded Picture Frame
This proprietary mode is intended as a method to transmit line 21 EIA-608 closed
captions in an NTSC system without incurring more bandwidth requirements.
Tiernan proprietary closed captions are supported on a composite analog NTSC or
component digital (525) format video signal.
Operational Considerations
Ensure that VBI teletext is disabled when closed captions are enabled, as teletext
overwrites all other VBI data.
Hardware Requirements
■
■
Encoders will properly process Tiernan closed captions with any of the
following modules: TVIP-6021, TVIP-6025, or TVIP-6001.
The TDR6 decoder processes VBI data in its standard configuration.
End-to-End Configuration
To configure the encoder and decoder for Tiernan proprietary closed captioning,
follow these steps:
Encoder
1. Ensure that Teletext is disabled. Issue the front panel command
Config>Service #>VBI>Teletext>Enable=off or the remote
TT ENABLE Off command.
2. Ensure that closed caption VBI data is included in the selected service video
input signal.

Demodulator Tuner SAW Filter
The demodulator tuner has a SAW filter (bandpass) for rejecting out-of-band
noise. It is important that you correctly specify the input L-Band frequency to
insure that the input spectrum is within the passband of the filter.
Check the Offset parameter to confirm that the acquired carrier is within 2 Mhz of
the location you specified when entering the RF and LO parameters.
For the procedures used to query to offset parameter and to correct the offset by
adjusting the RF and LO parameters, refer to the chapter on configuration.

Data Inversion / Spectral Inversion
In QPSK modulations, every symbol consists of two bits of data. These two bits
are commonly referred two as the I and Q samples. Data inversion occurs when
both I and Q are inverted. Spectral inversion occurs when either I or Q are
inverted. Spectral inversion is caused by selecting the lower sideband instead of
the upper sideband in the mixing and RF filtering process.
All Tiernan demodulators automatically check for and compensate for
data/spectral inversion.
Information Rate/
Symbol Rate/Channel
Spacing
This section provides rate definitions and relationships as well as information on
channel spacing.
Definitions
Information Rate (Bits/Sec)
Information rate is the rate of data leaving the demodulator measured in bits per
second. For Tiernan systems, the information rate is generally equal to the
aggregate transport stream rate.
For the TDR6, the information rate is the data rate parameter.
Channel Rate (Bits/Sec)
Channel rate is the rate of data in the demodulator, before the FEC decoding. The
channel rate equals the information rate plus the FEC encoding overhead
measured in bits per second.
Symbol Rate (Symbols/Sec)
Symbol rate is the rate of symbols being transmitted through the channel
measured in bits per second. For QPSK modulation, there are 2 bits per symbol.
You can query the TDR6 symbol rate using the DMD.x SRcommand. There is no
front panel equivalent for the SR command.
Aggregate Rate (Bits/Sec)
Aggregate data rate is the rate of the encoder output transport stream measured in
bits per second. The transport stream can be either a single transport stream or
several multiplexed transport streams. The aggregate rate is generally the
information rate going into the modulator or coming out of the demodulator.
Relationships
Information Rate = Aggregate Rate
Symbol Rate = 1 ⁄ 2*(204 ⁄ 188)*(1 ⁄ Code Rate)*Information Rate
where the code_rate can be 1/2, 2/3, 3/4, 5/6, 7/8.
The minimum required E /N level varies depending on the code rate. For a table

showing the relationship between the E /N level and the code rate, refer to the

Output Spectrum Width
To prevent intersymbol interference, the outgoing symbols are filtered by a
DVB-compliant transmit filter. The filter type is a square-root raised cosine filter
with roll-off factor alpha = 0.35. The result is that the output spectrum has a width
of (1.35 * Symbol Rate).

E /N Estimation Algorithm
b
0
Within the FEC decoder IC, the Viterbi decoder output is re-encoded and
compared to a delayed version of the original encoder input. Incoming bit errors
that are corrected will result in a difference between original input and the
encoded output. These differences are accumulated for a fixed amount of time.
This accumulation register can be read by the TDR6 microprocessor and gives an
approximation of the signal to noise level of the input signal. Once these reading
have been calibrated using an input with a known E /N , they are used by the

TDR6 to accurately estimate the E /N of the incoming signal.

Transmit pure carrier to precisely locate the center frequency
If the demodulator is supplying the DC to the LNB, then the spectrum analyzer must monitor the
L-band input using a T-junction. Insure that the spectrum analyzer input is protected using a
DC-block. Since the spectrum analyzer has an input impedance of 50 ohms, this method will also
double-terminate the input signal (i.e. lower it by 3 dB).
NOTE
The demodulator will acquire only if the input carrier frequency is equal to [(RF – LO) 2 MHz].
Once acquired, it is recommended that you optimize the RF parameter using the carrier offset status
parameter. For the optimization procedure, refer to the chapter on configuring the TDR6.
Diagnostic Commands
This section describes commands you can use for troubleshooting the
demodulator.
■
G4 – Use this command to display the demodulator IC registers.
Syntax – DMD.x G4 where x designates the demodulator that is the object of
the command.
■
■
Register Values – The register values are all in hexadecimal. The two
registers that are most useful for debug are Register 6 and Register 31.
Register 6 (Power Level) – This register should be almost equal to A0. This
indicates that the AGC loop is locked and the signal level is optimum at the
analog-to-digital converter inputs.
■
Register 31 (Status) – Only the three least significant bits are active.
■
■
■
Status[0] = 1 if the symbol clock is locked
Status[1] = 1 if the carrier phase is locked
Status[2] = 1 if the carrier frequency is locked
Note that the state of these three bits are reflected in the status LED’s.
G3 – Use this command to display the three decoder error count registers.
■
Syntax – DMD.x G3 where x designates the demodulator that is the object of
the command.
■
■
Register Values – The register values are all in hexadecimal.
Reed-Solomon Corrected – This register displays the total number of byte
errors corrected by the Reed-Solomon decoder. It is reset to zero upon
reaching max count.
Any substantial channel noise will cause this register to be greater than zero.
■
Reed-Solomon Uncorrected – This register displays the total number of byte
errors that were detected, but not corrected, by the Reed-Solomon decoder. It
is reset to zero upon reaching max count. For normal operation this register
must be zero.
Any non-corrected byte errors will result in some form of degradation in the
decoder.

Table Top Instructions
To install a Tiernan unit on a tabletop or other flat surface, install the rubber feet
included in the shipping kit, or place the unit on a rubber mat or other material that
will prevent the unit from sliding and protect the table top surface.
Ensure that the unit is placed on a stable surface of sufficient size and strength
where it will not be jarred or pushed off its surface. Ensure that all cables and
cords are out of the way and that they will not be tripped over, as this may cause
personal injury or serious damage to the unit.
To install the rubber feet, perform these steps:
1. Ensure that there are four rubber feet included in the shipping kit.
2. Break the feet apart from one another. Working with one rubber foot at a time:
a. Remove the protective backing
b. Place the foot under one corner of the unit, with the sticky side against the
unit.
c. Press the foot firmly against the unit. When you are finished, there should
be one rubber foot under each corner of the unit.
3. Ensure that the unit’s location and position provide the minimum required air
flow clearance.
Front Rack Mount
Instructions
To install a Tiernan unit in a standard 19-inch equipment rack using front
mounting brackets, perform these steps:
1. Ensure that there are two brackets and 4 screws in the front bracket kit.
One side of each bracket has small holes while the other side has large holes.
The small holes are counter-sunk on one side. The side which is not
counter-sunk is placed against the unit.

Safety Precautions
If rack-mounted units are installed in a closed or multi-unit rack, consider the
following items; further evaluation by a Certifying Agency may be required.
Ambient Temperature The ambient temperature within the rack may be greater
than the room’s ambient temperature. When installing the unit, ensure that the
required air flow for safe operation is provided.
Rack Stability During installation, consider weight distribution on the rack;
hazardous stability conditions may arise if units are loaded into the rack unevenly.
Input Supply Overloading of supply circuits could impact over-current
protection and supply wiring. To ensure that supply circuits are not overloaded
review the nameplate ratings.
Grounding Reliable grounding of this equipment must be maintained. Pay
particular attention to supply connections when connecting to power strips, rather
than direct connections to the branch circuit.
