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 tr ansmitted in more than one language, the desired language should be select ed. 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 hand ling, RS32 data output and mor e. 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 gene rator (LNC 22kHz) to get the correct frequency band,

polarisation or signal selection depending o n 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

, a

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

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.

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 (a nd video), teletext subtitling, a nd 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 la nguages of your choice, plea s e 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 langua ge 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 informatio n about the subtitling page and its la nguage 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 tho s 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 aud io 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 tha n one language component, the de sired 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 unde r the selected language.) If no predefined

3. TT1200 Output and connector description

3.1 1st IF

The 1st 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.

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.

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 scro lling through menus with the up/down keypad. When the desire d 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.

5.4 Setup menu

The Setup menu contains all the setup parameters for the TT1200. This menu may appear differently depending on the hardware configuration and the setting of the PSI (On or Off) parameter in the System Options menu. The menu in Figure 17 is for a TT1200 with additional audio channels. For a TT1200 without additional audio channels, the Audio2 and Audio3 manus will not be present. The submenus Demod and TV Service are mandatory when setting up a TT1200, but it is recommended to set up all the parameters in this menu, except the parameters under the Advanced submenu, which are optional. The basic setup procedure is explained in chapter 2. Some of the menus are described in more detail in the following sections. Also the options in the Advanced menu are described here.

Because of slightly different functionality between PAL/SECAM and NTSC/PAL M, the Setup menu appears slightly different depending on the video format selected in the Video format entry. If NTSC or PAL M is selected, the Teletext and Subtitling menus disappear, and the Caption menu appears.

Figure 17 shows the Setup menu and its submenus (except the submenus of the Advanced menu, which are covered in detail in section 5.4.5) in the case where PAL or SECAM is selected. This is the same as Figure 2, but is repeated here for convenience.

LNC mixing frequency [GigaHerz]. This frequenc y is given by the Low Noise Converter (LNC) in your antenna, and should be found in the documentation for the LNC. If you are in doubt, contact your LNC provider.

The LNC should mix the satellite frequency down to a frequency in the range of 950-2150MHz (L-band), which is the input frequency range accepted by TT1200. This relation is given by:

L-band freq. = Sat. Freq – LNC freq.

If the demodulator is in sync, the AFC (Automatic Frequency Control) offset between the configured L-band frequency and the actual L-band frequency will be found in the title line above the value of the LNC frequency in the LNC freq. menu. Ideally, this should be zero, but due to offset in the actual LNC frequency is may be something else. The LNC freq. parameter should be adjusted until the AFC offset is zero. This means that the demodulator is locked to the center ferquency of the satellite signal.

If this parameter is set to On, TT1200 wil generate a 22kHz signal on the demodulator input. This signal can be used to control external equipment, for example to select frequency band or polarization in the antenna.

Note that the 22kHz functionality is HW dependent. Even if the HW does not support the function, this menu may appear.

5.4.2 Selecting TV service and Audio services

This menu is used for selecting a particular service within a transport stream and is only visible when PSI/SI is enabled. The selection may be done by selecting the list of available services, or by entering the service identifier number. This description applies both for selecting T V service, and Audio2 and 3 services (if available). Please refer to Figure 17 for an overview of the menus.

A service may be selected by entering the service id. of the wanted service. This is done by editing the service id. entry. You accept the selected service by leaving the service id. field with the right arrow. If you have changed the service id. number, but do not want to accept it, you can cancel your selection by leaving the service id field with the left arrow.

5.4.2.2 Lines containing service names

A service may also be selected by choosing a service name from the list of available services. The service id field will be updated with the corresponding numeric service id. value.

5.4.3 Selecting TV language and Audio languages

The TV language, Audio2 language and Audio3 language menus are used to select language components (Audio, Teletext and subtitling) for TV, Audio2 and Audio3 channels, respectively. Please refer to Figure 17 for an overview of the menus.

This menu is only visible if PSI is set to on in the Setup ⇒ Advanced ⇒ System Options menu.

The language priority list is used for selecting video, sound, sub titling and Teletext streams. For each stream type, the stream corresponding to the language with the highest priority is preferred. If none of the languages in the list are present in the input stream(s), the input stream transmitted first in the PSI list is used. For subtitling, additional rules is checked to exclude displaying:

if the received languages are not in the priority list if the subtitling language has lower priority than the sound language

If the language is set to User d ef. the select language menu changes and the user may set the following: Video id: number of video stream Audio : three letters giving language (programmable by the user) DVB subt. : three lette rs giving requested language (pr ogrammable by the user) for DVB subtitling. TTX overl. : three letters giving requested language (programmable by the user) for DVB subtitling. TTX VBI : three letters giving requested language (programmable by the user) for DVB teletext. If there are more than one video stream in the service the user may select which of them that should be used by setting the video id. Numbering star ts on 0.

CA-mode Standard

Fixed Key

Aux module

This mode is used in the Viaccess, Conax, Nagravision and Mediaguard versions of TT1200. In this mode, the services are

descrambled in accordance with the CA system implemended in the software of the unit. If the received service is scrambled, a valid smart card is neccesary. Descrambling status and smart card information (if available) can be viewed in the Status ⇒ CA module menu. Note that it is not possible to select this mode for an Irdeto version of TT1200.

This mode is used when the received signal is scrambled with a fixed control word. When CA mode is set to Fixed Key, the Smart Card menu is replaced by a Fixed Key CA Setup menu, where the control words are manually entered. Please see section 5.4.5.1.2 for further information about this menu.

Note that this mode should is only used in Irdeto versions (software version number ending with ID)

This mode is used when an external module is needed for descrambling. Currently the Irdeto PCMCIA module is supported, for TT1200 Irdeto version. Note that it is not possible to select this mode for Viaccess, Conax, Nagravision or Mediaguard versions of TT1200.

Select input source. Is set to DVB or Demod (depending on the actual input interface), except for Irdeto versions, for which it is set to AUX. See also section 5.4.5.1.1

PSI on/off:

The TT1200 can be set up to select services in two ways:

• PSI = on: The service to be decoded is selected in the TV Channel ⇒ Select Service Menu.

The names of the services contained in the transport stream is displayed, and the user can select

service from the menu. The TT1200 will extract the corresponding service components (PID’s), based on the PSI/SI information in the transport stream. See 5.4.2 Selecting TV service.

• PSI = Off: If PSI is switched off, the TT1200 does not read the PSI/SI in the transport stream (if

present), and the user has to specify manually which PID’s to be decoded. In this case the TV Service, TV Language, Audio 2/3 Service, Audio 2/3 Language and PID info menus disappear (as they all are based on the contents of PSI/SI tables). Instead, the TV PIDs, Audio2 PIDs and Audio3 PIDs menues appear in the Setup menu. By selecting one of these menus the operator may set Video PID, Audio PID, PCR PID (usually equal to Video PID), teletext PID and Subtitling page manually. Figure 18 shows the Setup menu when PSI is set to Off. See section

5.4.4 for furt her explanation of manual configuration of PSI/SI.

Note also that the Favourites and CA-module menus will disappear when PSI = Off.

5.4.5.1.1 Configuration of conditional access

There are two parameters in the System Options menu that affects the conditional access; the CA- mode entry and the Input source entry. These parameters are preset from the factory, according to

the CA-version of the unit.

All TT1200 versions with Viaccess, Conax, Mediaguard or Nagravision CA, CA-mode is set to Standard. These CA systems are implemented in the TT1200 software, and do not require any additional modules. Note however, that a special software version (version number ending with MG) must be used in order to use Mediaguard CA.

In TT1200 versions with Irdeto CA an additional CAM interface module is used, on which an Irdeto CAM module may be inserted. The Irdeto descrambling is done in this module. In this case CA-mode is set to AUX module. Furthermore, since the descrambled signal from the CA-module is the input to the demux/decoding chips, Input source is set to AUX.

These parameters are preset from the factory, and should not be changed.

5.4.5.1.2 Fixed Key Descrambling

If CA Mode is set to Fixed Key in the Advanced ⇒ System Options menu, Fixed Key CA Setup menu appears in the Advanced ⇒ System Options menu.

The Fixed Key CA Setup menu allows the user to view a fixed keyword, with an even (E) and an odd (O) part. The fixed keyword is displayed as a 12-digit hexadecimal number (48 bits). Fixed Key descrambling is implemented according to BISS mode 1.

Testlines can be switched off if they are not required as a measure of cable network quality. Use the cut sides 16/9 on/off switch to handle 16/9 coded video.

Use the menu entry Vid. setup 525-ln when configuring the VBI handling re the VBI handling and picture format for your NTSC and PAL M video output. Test-lines can be inserted on line 17 odd and even field in the VBI. Testlines can be switched off if they are not required as a measure of cable network quality. Use the cut sides 16/9 on/off switch to handle 16/9 coded video. Use the GCR on/off entry to switch Ghost Cancelling Reference (GCR) on or off, and the Caption entry to control the closed caption insertion.

The PTS setup menu should not be changed unless there are specific continuity problems with a particular encoder or that the encoder has a known lip sync offset. The resolution of the hexadecimal number is 1/45kHz i.e. round 0.22µs. To for example add 40ms on the audio PTS the hexadecimal number 708 must be typed in. Remember that the original configuration is correct in terms of DVB compliant systems and should not be changed unless absolutely necessary.

5.4.5.2.1 Video Setup Menu – 625 lines and 525 lines video

In these menus the video functions available in 625 and 525 lines video formats are configured. The 625 lines menu is used for PAL and SECAM signals, and the 525 lines menu is used for NTSC and PAL M. In the 625 video entry, the user may select between PAL or SECAM output. VBI functions are testlines, information or signalling that is transmitted in the Vertical Blanking Interval (VBI) between video fields. The following VBI functions are available:

• Teletext. Only for 625 lines signals (configured in the Setup menu, see section 2.3.2.5).

• Video Programming System (VPS): The transport stream carries encoded VPS information about

each program, from which the decoder will generate VPS signalling in VBI. This signalling can be used for triggering a video recorder to record a program specified by the user. Only for 625 lines signals.

• Wide Screen Signalling (WSS): WSS can be used for automatic selection of aspect ratio (16:9 og

4:3) on the TV set. The transport stream carries information from which the decoder will generate WSS signalling in VBI. Only for 625 lines signals.

• sin(x)/x testline. This is a testline which is generated locally and inserted in line 335. Only for 625

lines signal.

• Sweep. Frequency sweep from 0.25MHz to 5.75MHz, on line 335. Only for 625 lines signal.

• Ghost Cancelling Reference (GCR): This function generates a special testline in VBI on the NTSC

or PAL M video output. This testline can be used by the TV set to detect and correct reflections in the received NTSC or PAL M signal. Only for 525 lines signal.

• Closed Captioning. Only for 525 lines signal (configured in the Setup menu, see section

2.3.2.5).

• Testlines

• Didon line: This is a testline that carries information about the current TV service. The

information is Service ID, Network ID and Transport stream ID. This line is generated by the TT1200 after selection of the program and is inserted in the video signal as a VBI line.The program information can then be extracted at the terminal (tv or video player) by specific equipment. The information can then be used by service providers for viewer statistics purposes.

The VPS and WSS info may be sent on a separate PID according to SI-DAT 486. In addition, the Video setup menus include the following parameters, which are explained later in this

section:

• Cut sides 16/9. If set to On, this parameter converts 16/9 video to 4:3 by cutting off the left and

right sides of the picture.

VBI Priority: In some cases, there may be a conflict when different VBI-data are assigned to the same VBI line. This

may be the case in lines 12, 14, 16, 17, 18, 19 and 2 0. Priorities to the different VBI data are assigned according to the table below (with priority 1 as the highest). The table applies for both fields, except for VPS, which is only present in the first (the VBI line number in the second field is given by adding 313 to the VBI line in the first field).

2 Teletext x x x x x x x

Legend:

(x) The default placing of the VPS- and VITS-data.

x Alternative or supplemental placing of the different VBI-data

For example, it can be seen from the table that both VPS and VITS (test lines) can override both

teletext in lines 16 to 20. The decoder vill attempt to insert suppr essed teletext lines if there are available lines in the VBI, if not the teletext lines will be discarded.

The parameters for 625 lines and 525 lines video, respectively, are as follows: 625 ln video format (PAL and SECAM)

Enable or disable Wide Screen Signalling {Off; MPEG-video; On (DVB)}. The

different settings may be interpreted as follows: Off: WSS is disabled, and the first half of line 23 will be blanked (i.e. set to black level) MPEG-video: Line 23 will be treated as MPEG video. This is useful in cases where WSS is encoded as video. On (DVB): If present in the transport stream (DRAFT prETS 300 294), WSS- data will be inserted in the first half of line 23. If the signalled aspect ratio differs from the actual aspect ratio, the WSS signalling is changed to reflect the actual aspect ratio of the video output. In the special case where no WSS data stream is present and the MPEG-video

aspect is 16:9, the decoder will locally insert code for “16:9-full format (anamorphic)”. Except for the four bits describing the aspect ratio, all other bits in the WSS will be set to zero. If no WSS data stream is present, and the MPEG-video aspect is 4:3, half of line 23 will be set to black level.

5.4.5.2.2 Audio setup menus

The audio output of the TV channel is configured in the TV audio setup menu. If the TT1200 is equipped with additional audio channels, the Audio2 and Audio3 are configured in the Audio2 setup and Audio3 setup menus, respectively. Here the user can enter the output level and the output connector you are using. The external equipment also often dictates the format of the output. In the modulator menu you can choose the type of modulation either mono or stereo. If you do not want to change the input audio format but let it p a ss through unchanged, use the transparent option. This option is particularly useful when sending two audio channels in one audio stream. This is called dual mono and will be output as two independent mono audio channels.

The parameters in the Audio setup menus are as follows:

Output level The output level from the decoder may be adjusted in steps of 1 dBu from -8

dBu to +3 dBu when balanced sound connectors are used, and by -14 dBu to -3 dBu when unbalanced sound connectors are used.

Modulator {Mono, Stereo, Transparent} The setting here should be according to the type of

equipment connected to the analogue audio output. In Mono mode, mono audio will be presented unaltered, while the two channels in a stereo audio will be mixed together in the decoder and presented as mono audio on the output. The same audio will then be found on both audio connectors. This will suit any external audio equipment that only expects mono audio as input. In Stereo mode, stereo audio will be presented unaltered as left and right channel,while mono audio will be presented on both connectors. The third mode, Transparent, is only significant if the selected audio is of the dual mono type; i.e. two mono audios sent as one stream in the MPEG transport

stream. If the external audio equipment expects the full dual mono audio, the correct setting is Transparent mode. In this case the decoder will present both the two mono audios on the output, one on each connector. In the case that the external audio equipment does not handle dual mono audio, Mono or Stereo mode should be selected. The decoder will then only present one of the two mono audios on the output, which one depends on the setting in the Select Component menu or the Dual mono setting. For any other type of audio than dual mono (i.e. mono or stereo audio), the

Transparent mode behaves as the Stereo mode. See Error! Reference source not found. below for further explanation.

Connector {Bal, Unbal.} Selects balanced or unbalanced audio output. See section 3.4.

The table below summarises what signals are present at the analogue audio outputs for different audio sources and menu settings. The

Left output and Right output columns refer to the output at the right and

left audio connector, respectively. “L” and “R” refer to the content of the left and right audio signal present in the transport stream. “1” and “2” refers to the audio signals in channel 1 and 2 respectively (the two mono signals present in the Dual Channel audio PID).

VIDEO PTS PROCESSING

2 different methods of processing video PTS values may be selected:

Standard mode:

The first line of the first field is aligned to the correct PCR value, +/- 1 ms. If neccesary, the PAL/NTSC sync signal is made non-continuous (broken) to obtain this. Breaks will (most likely) happen when a new service is selected. If PCR is non-continous or the video PTS phase is non-conitnuous, a sync break will also happen. If the incoming signal is fully DVB-compliant, this method will give the best lip sync and no PAL/NTSC sync signal br eak.

Other modes:

The first line of the first field is aligned to the correct PCR value, +40/-5 ms (PAL); +34/-5 ms (NTSC). The PAL/NTSC sync is never broken. This is for use with input signals that are not DVB-compliant with respect to video-PTS use.

AUDIO PTS PROCESSING

The audio frames are aligned to the correct PCR value, +5/-2 ms. Different selections in this menu results in adding a time offset to this presentation time.

MENU SELECTIONS

Standard : PTS is handled according to DVB specifications, both for video and audio.

PCR: Used to lock the local 27 MHz oscillator Video PTS: Max. +/- 1 ms incorrect. Sync breaks if needed. Lip sync: Max (sound after video) +6 / -3 ms incorrect Audio PTS: Max. +5 / -2 ms incorrect.

PCR: Used to lock the local 27 MHz oscillator Video PTS: Max. +40 / -5 (+34 / -5) ms incorrect. No sync breaks. Audio PTS: Max. +5 / -2 ms incorrect, with a fixed offset of 20 ms added. Lip sync: PAL Max (sound after video) +30 / -22 ms incorrect.

NTSC Max (sound after video) +30 / -16 ms incorrect.

Locked: Audio PTS is locked for the video PTS. PCR: Used to lock the local 27 MHz oscillator

Video PTS: Max. +40 / -5 (+34 / -5) ms incorrect. No sync breaks. Audio PTS: Max. +5 / -2 ms incorrect, with the offset calculated from the

video PTS processing added.

Lip sync: Max (sound after video) +6 / -3 ms incorrect.

Local: As for locked mode, but the local 27Mhz oscillator runs freely. PCR: Not used to lock local 27 MHz oscillator

Video PTS: Max. +40 / -5 (+34 / -5) ms incorrect. No sync breaks. Audio PTS: Max. +5 / -2 ms incorrect, with the offset calculated from the

video PTS processing added.

Lip sync: Max (sound after video) +6 / -3 ms incorrect. NOTE: Since the 27 MHz is not locked, the presentation erro r will change slowly towards higher

(lower) values when the local 27 MHz is too slow (fast). When the video presentation error crosses a max value, a frame skip or frame repeat is done. As a result, the audio is "moved" the same amount of time (40 or 34 ms) in the same direction.

Off: Incoming PCR and PTS values are not used at all.

5.4.5.3 Alarm Setup menu

Whenever an alarm condition occours, the alarm relay is activated (see section 3.6 Alarm connectors), and the System Status display will display Status: ALARM. The possible alarm conditions are given by a number of Status messages. Each of the status messages can be configured to activate one of three alarm levels:

ALARM

WARNING



DISABLED

The ‘-’ means that the error message is considered unimportant and should be ignored if it occurs. ‘W’ means that a warning messages is generated on the status display if the error message occurs. ‘A’ means that this error message is considered to be a serious fault, an alarm message is generated and the alarm relay on the TT1200 will be switched to ALARM.

Entering the Alarm Setup menu, the different status messages can b e edited by first selecting type of message.

Note that this menu is present only if RS232 Comm is set to LSData.

The following section describes the procedure for setting up the Low Speed (LS) data service on the RS232 port. The sections after that describes the LS Data menus in more detail.

5.4.5.4.1 Setting up the data service:

In the Advanced ⇒ RS232 menu: enter the LS Data menu.

1. The data service provided with the TT1200 must be configured in a purely manual way. The data

PID must be known to the operator. This PID is manually typed in as the Aux PID and the Mode can be either Manual or Format II which is an encoder specific format that you will have to contact Tandberg Television to be able to use.

2. The Output⇒Communication menu allows for the physical communication interface to be

configured. The baud rates supported go from 1200 to 115.2kbaud. Parity is either not used or even or odd. The number of data bits available is 5 to 8, and stop bits are 1, 1.5 or 2.

 Baud rates: 1200 to 115.2k  Parity: off, even or odd  Data bits: 5, 6, 7 or 8  Stop bits: 1, 1.5 or 2

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

3. The protocol used can be selected in the Output⇒TS-Parse menu. The options ar e All, TP

payload and PES Payload. These are typical ways of looking at transportstream contents. Option All transmits the whole transport packet which contains the programmed PID. Option TP payload output the complete transport packet just omitting the 4 byte header information and the adaptation field.

4. The output can be either bin (binary) or hex (hexadecimal). Binary is the natural unformatted

output. Hexadecimal output is formatted and especially useful together with a terminal program because the characters transmitted are printable characters. The buffering mechanism can either be programmed to be in flow or burst mode. In flow mode, the buffer size is 16kbyte and must not be filled more than this. It would result in loss of information. The other mode allows the user to buffer up 16kbyte of information and output this while the input is halted and the buffer is completely emptied. This is useful when the input rate is higher than the output rate of the data, and you want to inspect partitions of the data rather than the time continuos signal.

NB, Reserved PID’s: PID’s that are used by the PSI/SI engine: 0(PAT), 1(CAT), 16(NIT), 17(SDT) and 20(TDT) cannot directly extracted by the aux. data port. In order to output these PID’s you need to disable PSI SI handling by setting the System Setup⇒Setup⇒PSI menu parameter to off. All

these PID’s then becomes available to the user of the data port.

5.4.5.4.2 Low Speed Data Menu

The LS Data menu is present at the bottom of the RS232 setup menu when the RS232 Comm. is set to LSData . The LSData menu is used for configuration of the Low Speed (LS) data functions. The LSData menu has the following entries.

0RGH

The data mode has the following options: {Manual, Format #2}. When in manual mode the aux data menu has two sub menus, Output and Communication. Format #2 should only be used after consultation with Tandberg Television.

$X[3,'

The auxiliary PID may be set to an arbitrary value (0 to 8191). Operating the display allows for turning off the auxiliary output by setting the PID value one below 0 or one above 8191. The display values wraps around from the lowest

value (0) via a «not used» display to the highest allowed value (8191).

Flow mode where whatever received on the selected PID is transmitted directly. Burst mode can be used for analysing the input sequence of a PID which has higher

transfer rate than the UART can handle (Max 38.4k). The buffer will fill up and dump the contents out on the serial line. The buffer size is in both cases 16kBytes.

5.4.5.5 Remote control menu

This menu enables remote control and selects between the Tandberg Television protocol and a customer specific protocol. Note that if the Tandberg Television protocol is selected, the RS232

5.5.1 Alarm status

The Alarm Status menu is then used to investigate the status of the decoder and to check if any of the preset conditions have occurred. The Alarm Status menu will show the condition of the decoder with respect to the conditions selected in the Alarm Setup menu. Selecting one of the entries of the Alarm Status menu will show the status messages describing the current condition of the decoder. Each status message has assigned an alarm level, which may be one of three:

ALARM

WARNING



DISABLED

The ‘-’ means that the e rror message is considered unimpor t ant and should be ignored if it occurs. ‘W’ means that a warning messages is generated on the status display if the error message occurs. ‘A’ means that this error message is considered to be a serious fault, an alarm message is generated and the alarm relay on the TT1200 will be switched to ALARM.

Note that if the Alarm Hold parameter has been set in the Setup ⇒ Advanced menu, the alarm condition that caused an alarm, will be displayed some time after the alarm itself has disappeared. This delay is specified by the user in the Alarm Hold menu. The advantage of this is that it is possible to go back and review the alarm even after it has gone.

5.5.2 Demodulator Status Menu

This menu displays the status of the demodulator, and includes the following information:

Offset from the center value of the voltage controlling the internal

27MHz VCXO (Voltage Controlled Crystal Oscillator). The internal 27MHs VCXO is fed from a 16 bit D/A-converter. The

center value of this voltage is displayed as 0. The range is –9999 to 9999 (peak to peak controlling voltage). Dependent on temperature, age and other factors, this voltage is shifted from the center value. This is done by the internal PLL (Phase Locked Loop), which compare the internal 27MHz clock to the encoder’s 27MHz clock found by observing the incoming PCR values. Hence, any difference between the encoder and decoder clocks can be corrected.
