1. Introduction

1.1 Description of the TT1200 MPEG2-DVB Decoder

The TT1200 is a product in the Tandberg Television ASA growing MPEG2 receiver family. This one

channel 1U unit is designed for professional transcoding of one TV service into PAL, PAL M, SECAM

or NTSC video and one stereo audio pair.

TT1200 draws on more than 10 years of experience in designing high quality and professional

transcoding equipment for the reception of satellite TV channels at cable head-ends.

The decoder occupies 1U in an 19 inch rack and can easily be stacked on top of each other as the

internal fan sustains sufficient air flow from front to back.

The MPEG2 decoder include:

 Full range QPSK demodulator 2-30.5Msymb (not on versions with DVB ASI input)

 PAL/PAL M/NTSC/SECAM Video output

 One stereo audio pair

 A low speed RS232 data/remote control port

 Alarm relay used for switching purposes

Options available upon request are

 ASI output port

 ASI input port

 Two additional stereo audio pairs

The QPSK input module is capable of receiving a 2-30.5Msymb QPSK modulated signal. It supports

all FEC codes and can supply an LNC Voltage of 13V or 18V. A 22kHz tone can be inserted on the

LNC voltage DC output.

The TV channel comprises an audio and video output pair. The balanced stereo audio output interprets

layer II compressed audio. PAL, SECAM and NTSC video formats are supported. VBI handling

include the following:

 Testlines

 Teletext (625 lines video)

 Wide Screen Signalling (WSS) (625 lines video)

 Video Programming System (VPS) (625 lines video)

 Ghost Cancelling Reference (GCR) (525 lines video)

 Closed Captioning (525 lines video)

 Didon Line

 Sin(x)/x testline

 Frequency sweep

The configurable alarm relay can be used for redundancy switching or other external handling of alarm

events.

Different conditional access systems are supported. Viaccess, Conax, Nagra, Mediaguard, Irdeto, Fixed

Key CA (BISS mode 1) and a Tandberg Television proprietary system are available today.

Control of the decoder is achieved by manoeuvring the menu system available on the front panel LCD

using the four front panel keys. The multi purpose RS232 port gives the user a full remote control

protocol, data output, and software upgrade feature.

2. Installing the unit

2.1 General

The TT1200 MPEG2-DVB is designed for installation in standard 19 inch rack. Be sure that there is

sufficient space in front of the air inlet and outlet in order to provide the fan powered ventilation of the

unit with fresh air. Do not place the unit close to heat sources

2.2 Connection of external cables

Figure 1. TT1200

Figure 1 shows the decoder with its full configuration. The shaded area is available on request. The rest

comprise the standard configuration of the decoder. Two power supply variants are available, the

common 90-264Volt AC, and the more special purpose -48Volt DC. In case of the DC variant, a

different power connector is used.

Connect the external equipment to the decoder (QPSK signal cable, monitor, Cable network feed, audio

cables, remote control, alarm relay monitor/switch etc). References to the menu system will be written

in boldface fonts e.g. Demod Status.

The TT1200 does not require any external control equipment connected to complete the installation.

Simply connect the QPSK signal cable (F-connector) and the required output signals (video, audio,

data, etc.) to the decoder and plug the 220-110V or 48V power supply on.

2.3 Basic setup

This section describes the basic setup of TT1200. It describes the setup procedure and parameters that

are neccesary in order to get picture and sound at the output when receiving a DVB/MPEG-2 compliant

transport stream with PSI/SI (signalling information).

Basic setup includes tuning the demodulator to the desired satellite frequency and selecting which TV

service to decode. If audio, teletext or subtitling is transmitted in more than one language, the desired

language should be selected. All the setup parameters and submenus are found in the Setup menu. In

addition to the basic setup parameters TT1200 allows various options, such as VBI handling, alarm

handling, PTS handling, RS32 data output and more. These options are found in the Advanced

submenu in the Setup menu.

Because of slightly different functionality between PAL/SECAM and NTSC, the Setup menu appears

slightly different depending on the video format selected in the Video format entry. The Setup menu

when PAL or SECAM is selected is shown in Figure 2. If NTSC or PAL M is selected, the Teletext

and Subtitling menus disappear, and the Caption menu appears.

2.3.1 Tune the demodulator

Note that the demodulator menus are not present in TT1200 units with DVB ASI input.

First of all, the demodulator has to be tuned to the correct satellite frequency. This is done by entering

the parameters in the Demod menu:

1. Enter the LNC frequency (LNC Freq.) of your downconverter, in Giga Hertz. Typical

values are 9.7500, 10.0000GHz, 10.6000 or 11.3000GHz.

2. Enter the satellite signal parameters given for the desired transponder. These are the

satellite frequency (Sat. Freq), symbol rate (Symbol Rate) and inner code (Inner

Code).

3. In the LNC Volt entry, enter the power feed (18 or 13 Volts) required to give the

operation power for correct polarisation, frequency band or amplification depending on

your signal cable configuration. Switch the LNC Volt to Off if this is not required.

4. Use the 22KHz-signal generator (LNC 22kHz) to get the correct frequency band,

polarisation or signal selection depending on your signal cable configuration. If this is not

required leave in Off mode. Note that the 22kHz functionality is HW dependent. Even if

the HW does not support the function, this menu may appear.

5. Set Spectr inv to On if the QPSK signal you want to receive is the inverted spectrum.

Note that this must be done manually i.e. there is no automatic spectrum inversion sensor

implemented.

Note that the demodulator is capable of tuning to a signal that is offset from the LNC frequency by

950MHz to 2150MHz. The symbol rate limitations require the width of a signal to be within 2 Msymb

to 30Msymb. When all parameters are entered, allow the demodulator to search for some seconds. The

result is shown at the top right corner of the display, e.g:

M: 2.4dB.

The M: stands for Margin, and displays the margin, or difference in dB, between the actual input signal

level and a signal level giving Bit Error Ratio (BER) of 2×10

-4

in the viterbi decoder in the

demodulator. In other words, M: 0dB means that the signal level corresponds to a BER of 2×10

4

, a

negative margin value means that the signal level is below the level corresponding to a BER of 2×10

4

.

Correspondingly, a positive value means that the signal level is above this level. If there is No Sync

displayed here after waiting a few seconds, please check the parameters again. If this does not help,

check signal levels and the external cables etc.

Tel: +47 67 11 62 00, Fax: +47 67 11 62 01

2.3.2 Setting up the TV service:

When the demodulator is receiving OK as explained in the previous section, the TV service parameters

should be set up. Please refer to the menu in Figure 2.

2.3.2.1 Selecting which TV service to be decoded

First you must select which TV service you want to decode. Enter the TV Service menu and find a list

of services that can be seen by using the up and down arrow keys. Select the service you want to see by

pressing the right arrow key. Note that the demodulator must be working OK for you to find this list. If

there is no list of services, check the demodulator status and setup again. Also the service ID can be

typed in manually if this is known, and can thus be configured without the signal being present.

If you have connected a TV monitor to the composite output and speakers to the audio outputs (see

sections 3.3 and 3.4 for detailed description of the video and audio connectors, respectively), you

should now have sound and picture.

For a more detailed description of the TV service menu, please see section 5.4.2.

2.3.2.2 Selecting Language

If more than one language is sent in audio (and video), teletext subtitling, and teletext, the desired

language may be selected in the TV language menu. Please select the preferred language from the

existing predefined priority lists (the priority list can be viewed by scrolling the menu under the selected

language.) If no predefined list applies to the languages of your choice, please select the User def.

entry which gives you the option of manually selecting the language codes for all the components. This

is done by entering the three-letter language code (e.g. nor for norwegian).

You should now have picture and sound with the correct language components.

For a more detailed description of the TV language menu, please see section 5.4.3.

2.3.2.3 Selecting video format

The TT1200 supports PAL, PAL M, SECAM and NTSC composite video. Please enter the Video

format entry and select the video format that is appropriate for your configuration.

The TT1200 automatically detects whether the input signal is 525 lines (NTSC) or 625 lines (PAL or

SECAM) video and outputs the composite video according to this. For example, if the original signal is

625 lines, but Video format is set to NTSC (525 lines), the actual output is 625 lines PAL. But if

there is no appropriate input signal, there will be a black NTSC signal at the composite output in this

case. This means that the Video format entry is used for the following two purposes:

1. Select between PAL and SECAM output for a 625 lines video signal (the menu also includes a

PAL CN option, for future use), and between NTSC and PAL M for 525 lines video.

2. Select between 525 lines and 625 lines video format for black video output when no appropriate

input signal is available.

2.3.2.4 Enable or disable subtitling – PAL or SECAM

The Subtitling entry is used to enable or disable subtitling. Note that subtitling is only available for

PAL or SECAM video, and that this menu entry is only active if PAL or SECAM is selected in the

Video format menu. TT1200 supports two types of subtitling:

Tel: +47 67 11 62 00, Fax: +47 67 11 62 01

• Teletext Subtitling. Based on subtitling information carried in a specified teletext page. If present,

the decoder will find information about the subtitling page and its language in descriptors in the

transport stream signalling. If Subtitling is set to TTX.sub, the text in the specified subtitling

page is keyed into the video picture.

• DVB Subtitling. A bitmap based subtitling system. Due to the bitmaps, the system can easily

display letters in various fonts and colors. One of the key advantage is the ease by which “special

characters” such as thos found in the Asian languges can be displayed. The subtiling information is

carried by a single PID. The DVB Subtitling SW is based on ETS 300 743. For DVB subtitling the

Subtitling parameter should be set to DVB.

2.3.2.5 Enable or disable teletext – PAL or SECAM

The Teletext entry is used to enable or disable teletext in the composite video signal. Note that teletext

is only available for PAL or SECAM video, and that this menu entry is only active if PAL or SECAM

is selected in the Video format menu. If the transport stream contains teletext for the current TV

service and Teletext is set to On, the teletext information will be inserted in the Vertical Blanking

Interval (VBI) of the video signal, and may be viewed on a TV set with teletext capabilities.

2.3.2.6 Enable or disable closed captioning – NTSC or PAL M

The Captioning entry is used to enable or disable closed captioning. Note that closed captioning is only

available for NTSC and PAL M video, and that this menu entry is only active if NTSC or PAL M is

selected in the Video format menu. If the transport stream contains closed captioning information, this

will be inserted in line 21 in odd fields, if enabled. The inserted closed captioning information may be

in one of the following formats; ATSC, C-Cube or DiviCom.

2.3.3 Setting up the Audio 2 and Audio 3 services

TT1200 may optionally be delivered with two additional audio channels, called Audio 2 and Audio 3.

The shaded area in Figure 1 shows the additional connectors on units with Audio 2 and Audio 3. This

section describes how to set up these audio channels. If you do not have additional audio channels, you

may skip this section.

The explanation below is given for Audio 2. The exact same procedure applies for Audio 3.

2.3.3.1 Selecting Audio 2 service

In the same manner as for the TV service, you must first select which audio service you want to decode.

Enter the Audio2 Service menu and find a list of services that can be seen by using the up and down

arrow keys. Select the service you want to see by pressing the right arrow key. Note that the

demodulator must be working OK for you to find this list. If there is no list of services, check the

demodulator status and setup again. Also the service ID can be typed in manually if this is known, and

can thus be configured without the signal being present.

If you have connected speakers to the audio outputs (see section 3.4 for detailed description of the

audio connectors), you should now have sound on the Audio 2 outputs.

2.3.3.2 Setting up the Audio 2 language

If the service contains more than one language component, the desired language may be selected in the

Audio2 language menu. Please select the preferred language from the existing predefined priority

lists (the priority list can be viewed by scrolling the menu under the selected language.) If no predefined

3.1 1

st

IF

The 1

st

IF input is a 75 Ohm F connector. The demodulator takes both Ku-band and C-band, and has an

input frequency range from 950MHz to 2150MHz (true or inverted spectrum). The symbol rate range is

from 2Mbaud to 30.5Mbaud.

3.2 Conditional Access Smart Card Interface

In order to support different encryptions of MPEG streams, conditional access is implemented to be

able to decrypt the streams in the decoder. However, the implementation and solution varies between

the different Conditional Access vendors.

Generally, in order to support Conditional Access in any system, the PSI option in the decoder have to

be enabled. This makes the decoder able to receive the data streams which carries the information that

makes the decryption possible.

On T1200 hardware version B1 and higher, there are two slots for smart card readers. Which one to use

depends on what CA system is used, please refer to Figure 4. Note that in the case of Irdeto CA, an

additional CAM interface module and Irdeto PCMCIA CAM module must be installed.

3.2.1 Viaccess, Conax, Madiaguard and Nagravision CA versions

The system is based on using a smart card in the

smart card reader at the bottom right. The smart

card is to be inserted with the “micro-chip-side”

pointing upwards in the smart card slot, as shown

in Figure 5.

In these versions of TT1200, there is a blind plate

over the Irdeto CA smart card reader.

3.2.2 Irdeto CA system

The Irdeto CA system requires an additional CAM interface module and Irdeto PCMCIA CAM module

to be installed. When this is the case, the upper smart card reader is used, with the chip side of the

Irdeto smart card pointing downwards.

The CA module from IRDETO is inserted by first removing the top lid of the decoder by unscrewing

the phillips screws. The CA interface is present on the card located above the main circuit board. The

CA module is inserted into the CA interface by simply sliding it gently into the slot. Reassemble the

unit by screwing the top lid back on. In order to be able to descramble a IRDETO CA signal, a smart

card can now be inserted face down in the upper smart card reader, as indicated by the arrow below the

smart card slot.

Ghost Cancelling Reference (GCR) in VBI

There is a 15Mbit video rate constraint that apply. The decoding is performed on Main Profile Main

Level (MP@ML), which is the standard for cable headend feeds of today.

When the decoder is not receiving any MPEG information, the video output is black (i.e black signal)

with test-lines in VBI (if enabled). The video output can also be DC when alarm mode is set to DC.

3.4 Audio Connectors

Analogue stereo sound output, balanced (mini XLR):

 Stereo, mono or dual tone

The Audio output decodes Layer 2 coded streams with rates from 32Kbits to 384Kbit.

The operator can tailor the audio output to suit the external equipment present. This is done by

configuring the modulator and sound level controls. The modulator control allows the operator to

output the appropriate format to the external equipment regardless of the coding (stereo, mono, dual).

The connectors are of type Mini-XLR. Depending on the external equipment, the outputs can be used as

balanced or unbalanced. Figure 6. Pinout for the audio connectors shows the different connections to

achieve the different outputs.

The AUDIO connector pair is related to the video output of the TV-channel.

Advanced menu. When the output is configured to LSData, the decoder will still be able to receive

software upgrades and remote control port configuration messages. For further information see Sections

3.5.1.1 Remote Control and 5.4.5.4.2 Low Speed Data Menu. The pin configuration is shown in Figure

7 Pin configuration.

3.5.1.1 Remote Control

The TT1200 may be controlled remotely. Remote control configuration is done in the Remote

Control menu in the Advanced setup menu. The Remote Control feature enables the user to

control all parameters and features of the TT1200 from a PC through a RS232 Communication cable.

There are two remote control protocols available:

3.6.1 ALARM Connector

If an alarm condition occurs, the alarm relay will be activated after a delay specified in the System

options ⇒ Alarm delay menu entry. The pinning of the connector is given in

Figure 8. If an alarm occours, pin no. 8 will be activated.

The TT1200 handles various status messages from different parts of the system. The current overall

status of the decoder can be directly read from the ‘sleep display’. A more detailed list of possible

alarm conditions can be found in the Advanced ⇒ Status Setup menu. The different status

messages are configurable to represent an alarm condition, a warning or a no-condition, see section

5.4.5.3. If one of the currently present status messages represent an Alarm condition, the alarm relay

will be set.

Figure 9 Menu layout

The two arrows at the rightmost position of the LCD display indicate that the current menu has more

than one item. If the

arrow is visible, the list of items continues above the visible item, and if the

arrow is visible, the list of items continues below the visible item. Menu entries containing submenus

end with

>. The TT1200 menu tree is dynamic, and some menus are present only if certain hardware is

installed or if certain menus are configured a specific way. These menus are marked with a *.

The (sub)menus are made up of a sensible combination of types of items which may differ. The

TT1200 has 3 types of menu items. These are:

Sub-menu entries

An item that point to an available sub-menu in the menu hierarchy.

Non-editable items

Provides the user with information about the configuration and status of the TT1200.

Editable items

Allows the user to control a specific functionality of the TT1200.

In general, an item is found by scrolling through menus with the up/down keypad. When the desired

item appears on the display below the title bar, the item can simply be selected by pressing the right

keypad.

• If the item is a sub-menu entry, a new list of items will immediately be available. With the cursor

positioned to the left of any item in the current menu, the previous menu can be accessed at any time

by pressing the left key.

• If the item is a non-editable item, no action will be taken when selected.

• If the item is editable, the menu system enters the edit mode and a parameter can be set by selecting

a predefined value or entering a value/text in a numeric/alphanumeric field. The value of this field is

displayed at the rightmost position of the item’s menu line as shown in Figure 10. A detailed

description of how to navigate in the edit mode is given in Section 4.1.1.

character. If the current digit is the leftmost character then the menu system leaves the edit

mode.

Í

If the selected item is a editable field, the cursor moves to the digit right of the current

character. If the current character is the rightmost character then the menu system leaves the

edit mode and the new entry is accepted.

Î

If the selected item is a numeric field, the digit under the cursor is incremented by one. For text

fields the next valid alphanumeric value is displayed.

Ï

If the selected item is a numeric field, the digit under the cursor is decrement by one. For text

fields the previous valid alphanumeric value is displayed.
