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
data signals.

Option Modules The TDR6 has a modular construction which allows for easy

expansion. The TDR6 accepts up to six option modules and can be rapidly altered
to suit your needs.

Video Processing The TDR6 can be configured to support SDTV in NTSC and

PAL formats. Video output provides both analog composite and digital D1
MPEG-2 4:4:2 or 4:2:0 formats, which are automatically sensed by the decoder.

The TDR6 can also be configured to support decoding of HDTV signals in either
1080i or 720p formats through the use of an option module. HD Video output
provides 1.5 Gbps SDI.

Audio Processing The TDR6 provides decoding of up to two stereo or four mono

channels of program audio in standard definition configuration.
A total of four additional stereo (or eight mono) channels of MPEG audio may be

decoded using one additional option slot. Audio output is digital AES/EBU. Up to
four AC3 audio channels are supported using external AC3 decoders.

Auxiliary Data Delivery The TDR6 is able to decode and deliver uncompressed

optional data streams. This data may take the form of non-specific auxiliary data,
or, depending on the transmission site, may be data such as teletext or other video
or audio specific data. The installed option modules define the data types the
TDR6 can decode and deliver to the receive site.

In its basic configuration the TDR6 supports two channels of synchronous data up
to 2048 kbps or asynchronous data up to 34.8 kbps on EIA-232 and EIA-422
ports.

Input Interfaces The TDR6 can be configured for various inputs through the

selection of input option modules. For example, a TDEM-6110
QPSK/8PSK/16QAM demodulator module allows the TDR6 to perform as an
SDTV or HDTV IRD with four switchable L-band inputs.

Auto-Sensing Decoding The TDR6 features auto-sensing of the audio and video

and monitoring functions can be efficiently performed using the front panel.

The TDR6 menu structure will vary according to the option modules installed in
your unit, however the standard menus exist in any TDR6 configuration.

At-a-glance system status can be quickly determined by checking the front panel
power, fault and status LEDs.

Remote Control A remote unit, such as a computer terminal, is easily connected to

either the EIA-232 remote control port or Ethernet port allowing the TDR6 to be
configured, monitored, and controlled using character-based ASCII protocol.

Programmable Memory The TDR6 is a field deployable unit designed with a

nonvolatile, field-programmable memory that ensures retention of configuration
parameters in the event of power outages or during transportation.

Configuration Sets The TDR6 has three default configurations and allows you to

store up to four user-specified configuration sets.

up to 4.096 Mbps or RS-232 asynchronous communications up to 38.4 kbps

Both User Data ports are female, DB-9 connectors.

■ FAULT RLY (relay) – female RJ-11 connector that provides three

connections to create a form-C status relay
The fault relay indicates a non-normal, or fault, condition when power is

removed through a power failure, a power switch turned off, or an unplugged
unit. The fault relay can also report user-programmable faults.

A fault condition is indicated by contact closure between pins one and three,
and an open contact between pins one and six. Fault Relay pin assignments
are provided in the port pinout appendix.

■ ETHERNET – female RJ-11 connector that provides remote control of the

TRD6 over a network

NOTE

configuration whenever the unit is reset or powered up.

Correcting Mistakes Selecting Options from a List If you are selecting a parameter from a list, and

have not pressed the Enter button, use the Up or Down buttons to scroll to the
correct option.

Using the Keypad If you are entering a value with the keypad, and you have

not pressed the Enter button, you can either:

■ Press the Up button to change the value to 0, then enter the correct value

■ Press the Down button to delete the numbers (from right to left), then enter the

correct value

Front Panel

01-0870-401B 01/03 19

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

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 Sets the Viterbi code rate ■ QPSK: 1/2, 2/3, 3/4, 5/6, or 7/8

Sym Rate Sets the demodulator to the frequency of the incoming RF signal.

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.

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
successful to lock on the carrier in these cases.

Data Rate Sets the data rate of the transport data stream 2 to 48Mbps

LNB Power Sets the voltage of the LNB Off, 13 V, 18 V
Acq Range Defines the size of the frequency range over which the

demodulator will search for the carrier.

The Offset measures the difference, in MHz, between the actual

Details>Service: consists of two submenus, Number and Auto Select, which enable you to query and select the services available in
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:

■ Another service is selected

or

■ The selected service is no longer available in the transport

stream

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.

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.

Front Panel

Using a Remote Unit

In addition to the front panel, a remote unit can be used to configure and monitor
the TDR6. 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 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.

Configu r ing 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

Using a Remote Unit

01-0870-401B 01/03 31

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

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.

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.

32 01-0870-401B 01/03

Using a Remote Unit

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

Command =

■ 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.

Command =

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

❒ 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

and press Enter. In this example:

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

Configuring the TDR6

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

NOTE

nonvolatile memory.

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.

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

NOTE

changed to 38400 bps.
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

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.

Configuring the TDR6

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

01-0870-401B 01/03 49

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 where:

■ RF is the carrier frequency at the input to the LNB

■ LO is the local oscillator frequency within the LNB

RF LOÐ

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 LOÐ

b. Enter the result as the new RF parameter using the front panel

command

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:

■ Input: RF

■ Modulation: QPSK

■ RF Freq: 11.774 GHz

■ LO Freq: 10.750 GHz

■ Data Rate: 8.448 Mbps

■ Code Rate: 3/4

■ LNB Power: 13V

Configuring the TDR6

Step 2: By comparing your system requirements to the DVB-compliant settings,
you determine the following parameters must be changed:

■ Input

■ Modulation

■ RF Freq

■ LO Freq

■ Code Rate

■ LNB Power

Step 3: To change these parameters the following front panel or remote
commands can be used.

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.

QPSK Demodulator

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.

This section provides information on troubleshooting the QPSK demodulator in a
TDR6 configured with a TDEM-6110 option module.

Input Status LED Not Illuminated

If the Status LED is not illuminated, the demodulator, decoder, or the transport
stream is not locked. This problem may be caused by:

■ Receive signal E

■ Receive signal power level is to low

■ Receive carrier offset is wrong

Receive Signal Eb/N0 Level

level is to low

b/N0

The Eb/N0 value in the Details menu under Input/Status displays the estimated
E

level of the receive signal in units of decibels (dB).

b/N0

The minimum E

level required by the QPSK demodulator for flawless video

b/N0

reception at each Viterbi Code Rate is listed in the following table.

level drops below the minimum DVB requirement, the video

reception can be interrupted or of poor quality.

■ If the E

level is above the minimum DVB requirement, the TDR6 should

acquire the carrier, demodulate the signal, allow the decoder to lock the
transport stream, and provide decoded video and audio output.

For information on estimating the E

level, refer to the appendix on the QPSK

demodulator.

Troubleshooting

Receive Carrier Off set

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 ( ), which have been entered by the

RF LOÐ

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 Eb/N0 and power
levels are above the minimum DVB limits. If the receive signal E

and power

b/N0

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

level is above the minimum DVB limits. If the Eb/N0 is sufficient,

b/N0

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.

PAL

Lines 7 to 22 VBI Region

Line 23 First Line of Active Video

Tiernan VBI Data Transmission

01-0870-401B 01/03 71

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 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.

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.

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

Line 261 is Last Line of Active Video in Tiernan CC Mode
Last Line of Normally Active Video Is Lost (Line 262)

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.

command.

5. If your system requires you to manually set the type of VBI data to decode,
follow these steps:

a. Set the decoder VBI format control to manual. Issue the front panel

command

VBI CONTROL MANUAL command.

VBI>Format>VBI Format Cntrl=Manual or the remote

b. Set the VBI format to Tiernan closed captions. Issue the front panel

command

DVB 4:2:2 Expanded Windows, 16-line and 32-line

Tiernan encoders and decoders support both 16- and 32-line expanded windows
operations. As with normal video encoding, the first 6 lines of the VBI region
contain timing set-up information. Expanded Windows use the remaining lines in
the VBI region, either 16 or 32 per frame (8 or 16 per field), to transmit data.

DVB 4:2:2 Expanded Windows is supported on a composite analog or component
digital (SDI) format video signal. This standard supports both PAL/625 and
NTSC/525 format video standards, and can transmit any of the following VBI
services:

■ PAL mode: Teletext, PDC, WSS, and VPS

■ NTSC mode: ATSC Closed Captions, V-Chip, AMOL I and II, and VITC

Operational Considerations

■ Ensure that both VBI teletext and closed captions are disable when either 16-

or 32-line expanded windows are enabled, as teletext and closed captions
overwrite expanded windows data.

■ Chroma must be set to 4:2:2 for proper expanded windows operations.

Industry Standard LNB Frequencies

The tuner input frequency for the demodulator is divided into two components
(RF and LO) to correlate with industry standards. The following table lists the RF
range for common LNB LO frequencies.

RF Ranges for LO Frequencies

RF Range

(Mhz)

3450 - 4200 5150 950 - 2150 C band

12250 - 13000 11300 950 - 2150 —

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 SR command. 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.

Maximum Rates

Symbol Rates

The minimum and maximum symbol rates are:

■ Minimum = 1 Mbaud

■ Maximum = 30 Mbaud

Information Rates

The minimum and maximum information rates are provided in the following
table.

Maximum Information Rate

27.6 36.8 41.5 46.1 48.4

(Mbps)

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).

Eb/N0 Estimation Algorithm

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
TDR6 to accurately estimate the E

Note that the estimated E

reading is accurate only for relatively low Eb/N0

b/N0

of the incoming signal.

b/N0

, they are used by the

b/N0

readings (less than 10). This is because there are not enough bit errors at higher
E

to generate an accurate estimation.

b/N0

Estimating E

Sometimes it is desirable to be able to estimate the E

Using a Spectrum Analyzer

b/N0

of an input signal using

b/N0

a spectrum analyzer. The following equation will provide a reasonable
approximation.

E

/ N0 = 10 log10 [(10

b

D/10

- 1)(SR/IR)]

where:

■ D = Distance in dB from top of spectrum to noise floor

■ SR = Symbol Rate (symbols/sec)

■ IR = Information Rate (bits/sec)

To determine the symbol rate issue the command

DMD.x SR.

The symbol rate is not available from the front panel.
The information rate is the TDR6 data rate parameter. To determine the data rate:

■ Using the front panel, select Details>Input>Demod>RF_x>Data Rate where

x = A, B, C, or D

■ Using a remote unit, issue the command DMD.x DR

Demodulator Low Eb/N0 Alarm

The TDR6 issues a “low E

” fault if the Eb/N0 is ever 1 dB lower than the

b/N0

DVB specification. You should operate with at least a 2 dB margin to allow for
rain-fade and other conditions.

Troubleshooting This section provides information that may be helpful in troubleshooting

including:

■ Using a spectrum analyzer to check the configuration

■ Troubleshooting commands

84 01-0870-401B 01/03

Spectrum Analyzer

Following are ways you can use a spectrum analyzer to check the configuration of
the QPSK demodulator:

■ Confirm that an input signal is present

■ Confirm that spectrum is flat

■ Confirm that width conforms to (1.35

symbol rate)

*

Demodulator Application Notes

■ Measure C/N to estimate E

b/N0

where

❒ C is carrier power
❒ N is noise floor

■ Calculate the estimated E

b/N0

Refer to the equation for estimating Eb/N0 using a spectrum analyzer in a
previous section of this appendix.

■ 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.

Demodulator Application Notes

01-0870-401B 01/03 85

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

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

is 16.00 (no noise).

b/N0

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.
