The TDR60 is used for broadcast
television distribution and
monitoring, digital satellite news
gathering (DSNG), and
sports/event contribution feeds
that require reception and
decoding of professional quality MPEG-2 digital television signals.

For satellite broadcast networks, the TDR60 receives and decodes video at
programmable transport rates from 2 to 30 MSPS. The outputs include one NTSC
or PAL composite analog video, one serial digital (SDI) video, two analog stereo
audio, two AES digital stereo audio, one synchronous auxiliary data channel, and
one asynchronous auxiliary data channel.

DVB-teletext is automatically detected, processed, and included in the composite
PAL video output, according to the user configuration.

In addition to receiving DVB-compliant digital satellite signals, the TDR60 can
decode transport streams provided on the integral DVB-ASI input port. This
allows the TDR60 to decode transport streams that are received from terrestrial

To cable the signal output of the LNB downconverter to the TDR60, use an IFL
cable to connect the output of the LNB downconverter to the RF input port (J1) on
the back of the TDR60.

RF In Connector

J1 is an F-type, 75W, female BNC connector that accepts an L-band IF signal
input between 950 to 2150 MHz. The LNB DC output current is provided on the
return at < 350 mA.

Signal Strength and Cable Length

For optimum performance,
the input signal strength

LNB

should be between -65 dBm

and -25 dBm.

In general, the IFL cable
length should not exceed
200 feet. The IFL cable loss
should not exceed 25 dB to

ensure reliable receiver
operation over a broad range of satellite operating parameters and varying weather
conditions. If the IFL cable length must exceed 200 feet, install a line amplifier to
ensure the signal strength at the TDR60 is within the -65 to -25 dBm input signal
range.

After installing the IFL cable, measure the signal strength at the TDR60. For
optimum performance, the signal strength at the TDR60 should not fall below ­65 dBm.

If the measured signal strength at the TDR60 is less than -65 dBm, you may need
to reduce the IFL cable loss by shortening the length of the IFL cable and/or
installing a line amplifier.

Installing the TDR60

LNB Power

In the default configuration, the TDR60 does not supply DC power to the LNB.
However, the TDR60 can be configured so that the RF IN port outputs LNB DC
power at <350 mA DC at either 13 V or 18 V.

Cabling a Remote

Unit

The remote control port is a DB-9 male connector that provides a half-duplex RS­232 interface to the TDR60. The maximum data rate is 38.4 Kbps.

Remote control may be accomplished using either a standalone computer with an
asynchronous communications software application installed or a network
management system host computer with a bisynchronous communications
protocol.

Both the asynchronous and the bisynchronous communication protocols are
embedded in the TDR60 firmware, which allows the TDR60 to automatically
sense and use the appropriate communications protocol based upon the input
signal.

Cabling the Fault

Relay

The Fault Relay port, J3 FLT RLY, is a DB-9 male connector.
The fault relay is used in a redundant configuration. A Tiernan redundancy switch

monitors the output of the demodulators through the Fault Relay. If the primary
TDR60 faults, the secondary TDR60 automatically takes over operation.

A relay fault condition is defined as a unit hardware failure.
When the fault relay detects a fault condition, the fault relay trips, and the Fault

LED located on the TDR60 front panel illuminates.
The fault condition is indicated by contact closure between pins 1 and 3. The non-

fault condition is indicated by contact closure between pins 1 and 6.

LCD Display LCD Symbols

The front panel LCD and buttons were designed to help you navigate through the
menu quickly and efficiently.

There are four important symbols that appear on the LCD:

■ Arrow (→) ■ Asterisk (*)

■ Equal sign (=) ■ Colon (:)

Arrow As you are navigating through the menus, an arrow will often display on

the LCD. Depending upon where you are in the menu structure, this arrow denotes
the following information:

■ At a menu level the arrow indicates that there are additional items available at

that current menu level

■ In a list of parameters the arrow indicates that there are additional items

available in that parameter list

Asterisk While the TDR60 is executing a command or setting a parameter, an

asterisk (*) appears on the LCD, indicating that the TDR60 is processing
information. When the asterisk disappears, the process is complete.

Equal Sign Most parameters, though not all, can be modified in order to configure

the TDR60. Configurable parameters are followed by an equal sign, denoting that
the parameter option can be modified.

Colon There are some parameters that are automatically set for your system or

that are query-only parameters. These type of parameters are followed by a colon.
When a parameter is followed by a colon, that parameter can be viewed but not
changed.

Once the parameter is flashing, you can continue to press the select button to

scroll through the list of available options. However, for those options that
require a numeric value, the value must be entered using the numeric keypad
— the selection buttons will not increment a numeric value.

01-0868-401B 12/02 15

Up and Down Buttons The Up and Down buttons are not labeled, but are located

above and below the Enter button, respectively. Once a parameter is selected,
use the Up and Down buttons to scroll through its available options. If the option
is a numeric value, the Up and Down buttons can be used to increase and decrease
the numeric value.

Enter Button The Enter button is used to issue a command, such as the clear

history log command, or to set a parameter option, such as a video frame rate. The
Enter button performs the following tasks:

■ When the required command is displayed, the Enter button executes the

command.

■ When a parameter value is correctly displayed, the Enter button configures

the system with the new parameter value. The new values are then stored in
nonvolatile memory.

Numeric Keypad The keypad is used to enter a numeric parameter value. When

entering numeric values with the keypad, the Up and Down buttons can be used to
correct errors:

■ The Up button changes the value to 0; the correct value can then be entered

■ The Down button deletes the numbers, from right to left; the correct value can

then be entered

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 using the Selection buttons. 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 by

either using 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 TDR60 is reconfiguring the parameter to the new value, the

front panel is temporarily disabled.

The TDR60 configuration files are stored in non-volatile memory. When the TDR60 configuration
is changed using the front panel, the changes are automatically stored in non-volatile memory. The

LO Freq S ets the Local Oscillator frequency.

The RF frequency input range of the TDR60 is between 950 to
2150 MHz . To downconvert the satellite downlink RF frequency to
a frequency that is within the input range of the TDR60, you must
enter an LO frequency that is the difference between the satellite
downlink RF frequency and the TDR60 RF input frequency range.

Typically, the LO frequency required is provided by the satellite
carrier; however, if the LO frequency is not provided by the carrier,
use the following chart to determine the LO frequency.

Data rate*1/2*(204/188)*1/FEC code rate symbol rate=

The Data Rate (DatRate) and Symbol Rate (SymRate) must be
entered in Mbps and MSps., respectively. These values must
include a decimal point. For example, to enter a data rate of
8448000 bps, you would use the numeric keypad to enter the
following rate in Mbps 8.448 — the trailing zeros do not need to be
entered. To enter a symbol rate of 5000000 sps, you would type in
a 5 using the numeric keypad. In this case, the decimal point and
trailing zeros are not needed.

DatRate Sets the data rate.

The data rate is the data rate of the transport stream. To convert
the symbol rate to data rate, use the following equation:

Symbol Rate * 2 * (188/204) * FEC Code Rate = Data Rate

Note

: Only available when Input>Config>Input Type = Demod.

LNB Power Sets the LNB power. The TDR60 supplies the LNB power at 13V

or 18 V to allow an LNB downconverter to set the receive signal
polarization. If you do not need the TDR60 to supply the LNB
power, you should set the LNB Power parameter to Off.

Offset Query-only; displays a measurement in KHz of the difference

between the actual satellite downlink frequency (carrier frequency)
and the frequency determined by subtracting the LO Freq
parameter from the RF Freq parameter.

To achieve carrier (transport stream) lock, the difference between
the two frequencies, referred to as the Offset, must be less than
2 MHz ; however, to achieve optimum performance, the Offset
should be as close to zero as possible.

When the TDR60 is trying to lock onto the satellite downlink
frequency, the carrier Offset display varies and does not display a
single frequency for more than a few seconds. Once the TDR60 is
locked onto the satellite downlink frequency, the Offset displays a
measurement that indicates the number of KHz you need to adjust
your RF Freq parameter to achieve optimum performance .

Using a Remote Unit

In addition to the front panel, a remote unit can be used to configure and monitor
the TDR60. The chapter presents the following information for remote command
operation:

■ Configuring remote software parameters

■ Overview of remote communications

■ Instructions for issuing remote commands

■ Error messages

■ Remote command listing

For remote cabling information, refer to the chapter on installing the TDR60.

Any parameter changes made using a remote unit are not automatically stored in flash
memory. When the TDR60 configuration is changed using a remote unit, an operational
test should be performed to verify that the system is operating correctly. Then the new

NOTE

configuration should be saved by issuing the MC FLASH SAVE command.

If the TDR60 is reset prior to issuing the MC FLASH SAVE command, any changes made
using the remote unit will not be restored. Instead, the TDR60 restores the last changes
saved to flash memory. Once the configuration is saved using the MC FLASH SAVE
command, the TDR60 automatically restores the saved settings when the unit is reset or
powered up.

Configu r ing Remote

Software Parameters

After you have cabled the remote unit to the TDR60 remote port, perform the
following steps to establish remote communications:

1. Configure the communications software parameters of your remote unit to
match the following TDR60 remote port DVB default settings:

❒ Baud rate = 9600 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 TDR60 restores this list of default
communications settings whenever the TDR60 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 TDR60 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 TDR60 are turned on and plugged into

an active AC outlet

❒ Verify that the baud rate and parity of the remote unit communications

package match the factory default setting of the TDR60 remote interface.

Using a Remote Unit

❒ Verify that the cable between the terminal and the TDR60 is properly

connected.

❒ If you need assistance, contact Tiernan Customer Service.

Remote

Communications

Overview

The TDR60 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 TDR60 supports ASCII
protocol for remote communications.

Command Types

The remote unit accepts two different types of commands:

■ Execute commands direct the TDR60 to perform a specified action, such as

changing a configuration parameter.

■ Query commands direct the TDR60 to display the current setting of a specific

parameter or to display current status information.

All commands consists of a command mnemonic, which is followed by a space,
and the command instruction.

Command =

The TDR60 uses the following command mnemonics to group various
commands:

■ AD – audio decoder commands

■ DC – decoder services management

■ MC – clock, configuration, and remote port commands

■ PGCA – conditional access commands

■ QD – demodulator commands

■ UD – user data commands

■ VD – video decoder commands

Execute commands have an additional parameter which follows the command

instruction.

Using a Remote Unit

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 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 and 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.

The TDR60 performs the required function and displays the prompt (>) when it is
ready to accept another command.

For example, to set the remote port baud rate to 1200 bps, issue the command

MC RS232 BAUD 1200

■ The command mnemonic is MC RS232 followed by a space

■ The command instruction is BAUD followed by a space

■ The parameter is 1200

and press Enter. In this example:

Query commands are issued by typing the command, without a parameter, and
pressing Enter. The TDR60 responds to the query by displaying information on
the remote display.

For example, to query the remote port baud rate, issue the command

MC BAUD

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

■ There is no parameter since this is a query command

The TDR60 responds by displaying the baud rate on the remote unit.

T yping Remote

Commands

Using a Remote Unit

Remote commands are not case sensitive. Commands may be entered in lower
case, upper case, or a combination of both.

Entering Parameter Values

Some command parameters must be enter as a numeric value, which is
represented by the pound sign <#>. If more than one pound sign is shown for a
given parameter <###>, you must enter a number for each pound sign. When you
issue a command containing a numeric value, do not type in the pound sign (#)
nor the bracket <> signs; enter only the numerical value for the parameter.

Configuration

Procedure

Whether you use the front panel or a remote unit to configure the TDR60, perform
the following steps to configure your system:

1. Make a list of your operational requirements. 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)
❒ DC voltage required by LNB (LNB power)

2. Determine which TDR60 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 TDR60 to the default configuration.

5. Configure the TDR60 with any new parameters.

6. Save the configuration.

7. Ensure that the encoder is correctly configured to operate with the TDR60
parameter settings. As part of this process verify that the parameters you
entered are correct.

Configuring the TDR60

01-0868-401B 12/02 39

Quick Start

Configuration

If your site requirements match those of the DVB operating parameters, you may
be able to begin operations using the Quick Start Configuration.

The DVB configuration consists of a standard set of operating parameters that
allow you to quickly and easily begin operations. When configured to the DVB
default settings, the TDR60:

■ Decodes audio channel A and the video channel at the default DVB rate

■ Decompresses the channels

■ Does not enable either of the user data channels nor audio channel B

To set the TDR60 to the default configuration and immediately begin operations,
follow these steps:

1. Set the TDR60 to the appropriate default configuration.

2. Set the local date and time.

3. Select a service.

The TDR60 video decoder and the audio decoders are fully auto-detecting, which
means that the TDR60 automatically sets the video and audio parameters based on
the incoming service signal.

Step 1: Setting the DVB Default Configuration

Using the Front Panel to Set the Default Configuration

To initialize the TDR60 to a default configuration using the front panel, perform
the following steps.

1. From the MPEG Receiver/Decoder main menu, select Control.

MPEG2 Receiver/Decoder

Even if the current configuration displayed on the LCD is the correct configuration for your
requirements, some or all of the parameters may have been manually changed since the unit was
initialized. To ensure that all of the TDR60 parameters are set to the factory default configuration,

Using a Remote Unit to Set the Default Configuration

To initialize the TDR60 to the default configuration using a remote unit, issue the
following command:
parameter,

When the TDR60 is set to the DVB default setting, the remote port baud rate is set to 9600 bps. If the
remote unit is set to communicate with the TDR60 at a baud rate other than 9600 bps, immediately
after the DVB default command is issued, the remote unit will not be able to communicate with the
TDR60. To resolve this issue, the equivalent parameter in the software settings of the remote unit

NOTE

must be changed to 9600 bps.

DVB

MC FLASH <string> where <string> is the default

However, the remote unit software settings must not be changed before issuing the DVB default
command to the TDR60, as the remote unit will not be able to communicate with the TDR60.

Step 2: Setting Local Date and Time

To set the date and time using the front panel:

1. From the Control menu select Clock>Date.

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

<hh:mm:ss>

is the current time.

TDR60 Detailed Configuration Procedure

To configure the TDR60 to your site-specific requirements, follow the
Configuration Procedure found at the beginning of this chapter.

Example

All examples presented in this section follow the TDR60 Configuration Procedure
presented at the beginning of this chapter and use the DVB factory configuration
as the default.

In the TDR60, both the video decoder and the audio decoder are fully auto-detecting, which means
that the TDR60 automatically sets all of the video and audio parameters required for operation based
on the incoming service signal. Since the TDR60 audio and video decoders are auto-detecting, the
only TDR60 parameters you must configure to establish communications are those required for the

NOTE

demodulator and service selection.

This example configures the TDR60 to a basic SCPC setup. Use this example as a
guideline, substituting your site-specific parameter values as required.

Step 1: In this example, assume that the following is a list of your TDR60

operational parameters:

■ RF Freq: 11.774 GHz

■ LO Freq: 10.750 GHz

■ Data Rate: 8.448 Mbps

■ Code Rate: 3/4

■ LNB Power: 13V

Step 2: After comparing these operational requirements against the TDR60 DVB

parameters, it is determined that the following parameters need to be set:

■ RF Freq: 11.774 GHz

■ LO Freq: 10.750 GHz

■ Code Rate: 3/4

■ LNB Power: 13V

Since the TDR60 audio and video decoders are auto-detecting, the audio and
video parameters do not need to be set.

Configuring the TDR60

Step 3: The front panel menus used to change the required parameters are:

Parameter Front Panel Menu Remote Command

RF Freq Input>Config>RF Freq = 11774 QD RF 11774
LO Freq Input>Config>LO Freq = 10750 QD LO 10750
Code Rate Input>Config>Code Rate = 3/4 QD CR 3/4
LNB Power Input>Config>LNB Power= 13V QD LNB 13V

Step 4: To configure the TDR60 for this example, you first initialize the unit to

DVB default settings.

Step 5: Once the TDR60 is set to the DVB default settings, all other required

parameters can be set.
If using the front panel, perform the following steps:

1. Select Input> Config. The RF Freq is displayed. Using the numeric keypad,
type the RF frequency,

11774 and press Enter.

2. Press Next to advance to the LO Freq parameter.

3. Using the numeric keypad, type the LO frequency, 10750, and press Enter.

4. Press Next and advance to the Code Rate parameter.

5. Scroll through the list of code rates and select the required parameter,

3/4.

6. Press Enter to set the code rate.

7. Press Next to advance to the LNB Power parameter.

8. Scroll through the list of LNB power parameters and select the required
parameter,

13V.

9. Press Enter to set the LNB power.

The demodulator is configured.

10. Set the date and time

11. Select the service, if required.

Step 6: Save the configuration.
Step 7: Ensure that the decoder is correctly configured to operate with the

encoder. As part of this process verify that the parameters you just entered are
correct.

SCPC Selection For SCPC signals, the TDR60 automatically selects the available service. View

the selected services using the front panel Service menu or the remote DC PROG
command. The TDR60 displays the current service.

If the TDR60 displays

No Services Available, verify that the Status LED is

illuminated. If the Status LED is not illuminated, refer to the chapter on
troubleshooting procedures.

01-0868-401B 12/02 43

MCPC Service

Selection

The TDR60 automatically selects the first authorized service in the MCPC signal,
then selects the audio channel based upon the language option you selected in the
Preferred language parameter. If none of the audio channels in the authorized
service match the setting of the Preferred language parameter, or if only one audio
channel is available, the TDR60 selects the first audio channel in the authorized
service.

To select a service from an MCPC signal using the front panel, follow these steps:

1. Select Service>Available Services.
The name of the current service is displayed.

If the LCD displays No Services Available, verify that the Status LED is
illuminated. If the Status LED is not illuminated, refer to the chapter on
troubleshooting.

2. Scroll through the list of available services until the service you required is
displayed and press Enter.

Setting the RF and LO

Frequencies

Although you must enter the RF frequency and your LO frequency while
configuring the TDR60, the TDR60 actual input signal frequency is the DVB
compliant modulated L-band carrier. The input signal frequency (L-band carrier)
is equal to the specified RF frequency minus the specified LO frequency.

If the entered RF or LO parameters are incorrect, the actual carrier frequency will
be different from the programed carrier frequency.

The Offset parameter measures any difference, in MHz, between the actual carrier
frequency received by the TDR60 and the carrier frequency the TDR60 calculates
by subtracting the LO parameter from the RF parameter.

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.

Check the Offset parameter and adjust the RF and LO parameters if necessary.

To adjust the RF and LO parameters:

1. When the decoder is locked onto the receive carrier, query the offset
parameter using the front panel
remote

QD Offset command.

Input>Status>Offset menus or the

The Offset parameter must be less than 2 MHz to achieve carrier lock. For

Fault Reporting and

Monitoring

The TDR60 has an internal micro- controller that continually performs real -time
monitoring of system conditions. When the unit detects a fault, one of the three
front panel LEDs are triggered, the fault it is stored in the fault history log and,
depending upon the type of fault, the fault may be viewed by querying the current
faults.

Front panel LED Indicators

At-a-glance system status is quickly determine by checking the front panel LED
indicators.

■ Status LED
❒ ON – the Status LED illuminates green when the demodulator, decoder,

and transport stream are all locked

❒ OFF – if the Status LED is not illuminated, at least one of the following is

unlocked: the demodulator, decoder, or transport stream.

■ Fault LED
❒ ON – the Fault LED illuminates amber when one or more system faults

exist.

❒ OFF – if the Fault LED is not illuminated, no current faults exist

■ Power LED
❒ ON – the Power LED illuminates green when the unit is powered on
❒ OFF – if the Power LED is not illuminated, the unit is powered off

Troubleshooting

Current Faults

Current faults are reported real-time, which means that only conditions that are
present at the time of the query are displayed, regardless of what fault conditions
have existed in the past.

Four types of problems generate a current fault on the TDR60:

■ Demultiplexer control FIFO overflow

■ Demultiplexer control input signal loss

■ QPSK demodulator bad E

■ QPSK demodulator input signal loss

b/N0

To determine if problems other than current faults exists, you must view the fault
history. All current faults are also recorded in the fault history log.

If a fault condition clears or no current faults exist, No Faults displays when
Current Faults are viewed.

exist, the fault history log must be viewed.

NOTE

Viewing Current Faults Using a Remote Unit

To view current faults using a remote unit, issue the FC command. The TDR60
responds with either

No Faults, if none are present, or one or more fault

messages.

Troubleshooting

For example, assume that the video input source is interrupted or disconnected.
You issue the

-------------------------------------------------­DC Input Signal Loss

FC command to view the current faults. The remote unit displays:

The query response shows:

■ The type of information queried — current faults

■ A listing of all current faults. Individual faults do not include a time tag since

they were occurring at the time the query was issued.

To determine the time that the fault initially occurred, you must query the fault
history log. For example, the loss of input could have initially occurred several
hours prior to this query.

Fault History Log

The fault history log is more than just a list of current faults that have occurred
over a period of time. The TDR60 can detect a variety of other hardware and
operational faults that are not reported as current faults. These faults are stored in
the fault history log in addition to any current faults that have occurred.

All faults are saved in the fault history log until one of the following events occur:

■ The unit’s power is turned off or the unit is reset

■ The fault history log is cleared by selecting Faults>Clear from the front panel

or issuing the remote command

FH 0.

The fault history log stores up to 20 occurrences of each type of fault. After 20 occurrences of one
fault have been logged, the TDR60 stops logging that fault until the fault history log is cleared.
Therefore, you should periodically view and record any faults stored in the fault history log, then

NOTE

clear the log to ensure that an accurate history of all faults is recorded.

Individual faults include a time tag. The time tag allows you to determine how
often a particular event or fault is occurring and to track the performance of
internal components. The TDR60 maintains an internal run-time clock, which is
used to time-tag faults and other events to help you monitor system performance
and diagnose problems.

Initialization Self-Test

Function

In addition to internal fault monitoring, the TDR60 automatically performs self­tests during the initialization process. If a failure is detected, a fault is displayed to
alert you to the problem.

If the TDR60 did not display a fault during initialization, but is not operating
properly, perform the following diagnostic steps:

1. Verify that the unit is configured correctly for your requirements.

2. If the system is configured properly, but still not operating correctly, issue the
front panel or remote command to reset the TDR60 to the defaults.

3. Reset any custom configuration parameters specific to your site.

4. If the unit is still not operating properly, query the current faults to determine
if a current fault exists. Correct all current faults.

5. Query and review the fault history log. Correct all faults, if possible.

6. Clear all faults.

7. Query the current faults and the fault history log. Correct all faults.

Carrier Offset

The carrier offset displays a measurement, in KHz, of the difference between the
actual receive carrier frequency and the frequency determined by subtracting the
LO Freq parameter from the RF Freq parameter. To achieve carrier (transport
stream) lock, the difference between the two frequencies, as shown in the Offset
parameter, must be less than 2MHz; however, to achieve optimum performance,
the Offset should be as close to zero as possible.

When the TDR60 is trying to lock onto the receive carrier, the carrier offset
display varies and does not display a single frequency for more than a few
seconds. Once the TDR60 is locked onto the receive carrier, the offset displays a
measurement that indicates the number of Hz that you need to adjust your RF Freq
parameter. To adjust the RF frequency:

1. Check the offset parameter after the TDR60 has locked onto a frequency. To
query the offset, use the

Input>Status>Offset menu.

2. If the offset is greater than zero, subtract the value of the Offset from the
current value of the RF Freq parameter RF – LO = New RF

3. Enter the difference as the new RF freq parameter.

4. Check the offset parameter again to verify the new value.

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 troubleshooting.

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.

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.

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.
The formula for converting the data rate to the symbol rate is provided in the
chapter on using the front panel.

Aggregate Rate (Bits/Sec) Aggregate rate is the data rate of the encoder output

transport stream. The transport stream can be either a single transport stream or
several multiplexed transports streams. The aggregate rate is generally the
information rate going into the modulator or coming out of the demodulator.

Output Spectrum Width

To prevent intersymbol interference, the outgoing symbols are filtered by a DVB­compliant 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).

Estimation Algorithm

E

b/N0

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 the original input and the
encoded output. These differences are accumulated for a fixed amount of time.
This accumulation register can be read by the TDR60 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

Diagnostic Commands

This section presents demodulator troubleshooting commands.

QD G3

Use this command to display the decoder registers. The register values are all in
hexadecimal.

The registers that are most helpful for troubleshooting are described in this
section.

Register 8 (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.

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 maximum count. For normal operation this register must be
zero.

Any non-corrected byte errors will result in some form of degradation in the
decoder.

Viterbi Bit Error This register displays the number of channel bit errors during the

last measurement period. This register is used to estimate E
zero, the E

is 16.00 (no noise).

b/N0

. If this register is

b/N0

Any channel noise will cause this register to be greater than zero.

QD OFFSET

Use this command to confirm the location of the carrier. The definition of this
query is:

OFFSET = Actual RF - Programmed RF

The units are in Hz.

Tiernan VBI Data
Transmission

D

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 encoders and decoders support one or more methods for
transmitting VBI data:

■ TE6000A and TE6000 – software V2.21 or later

■ TDR60 – software V4.10 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 inter­operate with all other vendor’s equipment that is found to be compliant with these
industry standards.

Tiernan’s TE6000 and TE6000A encoders and the TDR60 decoder can process
data contained in the VBI region of a video signal according to the following
methods and standards:

■ DVB-Teletext: – DVB standard for transmission of World System Teletext

(WST) included on a composite analog PAL format video signal.

■ ATSC-CC – ATSC standard for transmission of Line 21 closed captions

included on a composite analog NTSC format video signal.

■ 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.

Tiernan VBI Data Transmission

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.

DVB Teletext

Tiernan encoders and decoders process VBI teletext data within a video signal
according to WST standards. Teletext is supported on composite analog PAL
format video signal only.

Hardware Requirements

■ Encoders require a TVIP-6025 module.

■ The TDR60 decoder processes VBI data in its standard configuration.

Operational Considerations

VBI teletext should not be enable with other VBI encoding formats, as teletext
overwrites all other VBI data.

End-to-End Configuration

To configure the encoder and decoder for Teletext processing, follow these steps:

Encoder

1. Ensure that Teletext VBI data is included in the selected service video input
signal.

ATSC Closed Captions

Tiernan encoders and decoders support industry-standard ATSC EIA-608 closed
captions. On the encoder side, the data found on line 21 is stripped out, placed in
the picture header, encoded and transmitted. At the decoder end, the data is
processed and re-inserted on line 21 for proper broadcasting.

ATSC closed captions are supported on a composite analog NTSC 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 require a TVIP-6025 module.

■ The TDR60 decoder processes ATSC closed captions.

End-to-End Configuration

To configure the encoder and decoder for ATSC closed captioning, follow these
steps:

Encoder

1. Ensure that Teletext is disabled. Issue the front panel command

Config>Service #>VBI>Teletext>Enable=off

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.

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 TDR60 decoder processes VBI data in its standard configuration.

Front Panel Commands for Encoder Configuration

Teletext Commands

Config>Service # >VBI>Teletext — used to configure the encoder to transmit teletext data

Enable Configures the encoder to transmit

teletext information

Data ID Setting determines is EBU data

included in the Teletext. Values from
0x10 to 0x1F reflect EBU data.

Data Unit ID Data Unit ID defines if there are EBU

Teletext sub-titles included in the
data.

ATSC Closed Captions Front Panel Commands

Config>Service # >VBI>CC — used to configure the encoder to transmit closed captions

ATSC CC Configures the encoder to transmit

ATSC closed caption information

■ off – does not encode any teletext

information (default)

■ all – encodes entire VBI teletext area; i.e.,

allocates bit-rate to include maximum
number of Teletext lines

■ auto – automatically allocates bit-rate to

include only the number of detected
Teletext lines.

0 to 255
Default: 1

Data Unit ID has range from 0 to 255. Values
are:

■ 2 = EBU Teletext non-subtitle data is

included (default)

■ 3 = EBU Teletext subtitle data is included

Note

: Data Unit ID must be set to 2 or 3 for

proper decoder operation.

■ on – encodes ATSC VBI information

■ off – does not encode any ATSC VB I

information (default)

not

Tiernan Closed Captions Front Panel Commands

Config>Service # >VBI>CC — used to configure the encoder to transmit closed captions

Tiernan CC configures the encoder to transmit

Tiernan closed captioning
information

The Tiernan CC transmission
described in this document is

Tiernan proprietary

decoders accommodate the Tiernan

. Only Tiernan

CC feature described in this
document:

Note

: Tiernan CC should
implemented in PAL mode, as the
closed caption information will be

not

be

decoded and placed on line 22 of
the video.

■ on – encodes two lines of VBI information 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.

■ off – does not encode any VBI information

(default)

Note

: Data transmitted in the VBI region using
the Tiernan CC command will experience a
degradation in quality given the inherently
“lossy” compression of MPEG.

Expanded Windows Front Panel Commands

Config>Service # >VBI>Expand — used to configure the encoder to transmit data in 16-line or
32-line expanded windows mode

VBI_PassthruConfigures the encoder to transmit

either 16 or 32 lines of VBI
information

■ Off – disables expanded windows mode

(default)

■ 16- line – enables 16-line expanded windows

mode

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.
