Introduction

1.4 Guided Tour

1.4.1 Construction

The Receiver is constructed using a screened fan-ventilated chassis. All
operational inputs and outputs are via the rear panel connectors. The unit
may be operated free-standing on a horizontal flat surface, or mounted in
a 19-inch rack. 1RU rack height is required. It is important that horizontal
airflow is not obstructed, to maintain the airflow required to cool the unit.

1.4.2 Front Panel Controls

Overview

The front panel is fitted with a keypad that is used to set up and monitor
the unit. Information on the use of these controls is given in Chapter 3,
Operating the Equipment Locally. Figure 1.2 gives an overview on how to
navigate the menus. Figure 1.3 explains how to edit these values once a
menu item is selected.

3.4.4 Setting Up the Transport Stream Output

Overview

The TT1220 unit might be fitted with an optional ASI output. This output
can be configured to either output the incoming transport stream ‘as-is’,
or, depending on configuration, output the transport stream with the
selected service descrambled.

Either way, the entire transport stream is output. Null packets are not
removed, and PIDs can not be filtered or remapped. The effective bit-rate
is the same as on the input.

4.1 Remote Control

4.1.1 Introduction

The TT1220 can be remotely controlled in a variety of ways. The basic
control methods are:

• RS-232 control methods:

 NCompass Control and Monitoring
 Third-party application (using TANDBERG RS-232 control protocol)

• Over the air control methods:

 TANDBERG Director

Common for all control methods is that the TT1220 needs to be set up to
accept the remote control handling. Once in remote control mode, it
cannot be locally controlled unless the remote control is deactivated.

4.1.2 Remote Protocol Control Documentation

The protocols used for remote control are the TANDBERG RS-232 control
protocol and the TANDBERG Director Over-the-Air control protocol. Neither
of these protocols are described, or intended to be in the scope of this
manual.

For information about these protocols, please refer to the remote control
documentation, or contact TANDBERG to obtain this information.

NOTE…

The remote control protocols are not contained as a part of the product. An additional license fee, NDA
or other agreement with TANDBERG may be necessary to obtain the information required to control
the product remotely.

4.1.3 Configuring the Unit for Remote Control Via RS-232

For the unit to be controlled via RS-232, the RS-232 port has to be
configured to the same settings as the host controller system. The control
mode of the TT1220 also needs to be set to remote.

4.1.5 OAC Lockout

Overview

Once the unit is in OAC control mode, it is possible for the remote control
operator to issue a local lockout command to the Receiver. This will
effectively deny the local user access to configuring the unit.

However, if a situation occurs whereby the local user needs to regain
control over the unit, without a local lockout relinquish command being
sent from the OAC control PC, a four digit PIN may be entered through the
keypad.

The PIN is created at lockout time by the user. To obtain the PIN, please
consult the person responsible for the administration of the unit.

TANDBERG Help Desk will not be able to provide you with the Local lockout PIN, as it is uniquely

Glossary

B3ZS

Bipolar with Three Zero Substitution: A method of eliminating long zero strings in a transmission. It is used to

ensure a sufficient number of transitions to maintain system synchronisation when the user data stream contains
an insufficient number of 1s to do so. B3ZS is the North American equivalent of the European HDB3.

Backward Compatibility Refers to hardware or software that is compatible with earlier versions.
BAT

Bouquet Association Table: Part of the service information data. The BAT provides information about bouquets.

It gives the name of the bouquet and a list of associated services.

baud rate

The rate of transfer of digital data when the data comprises information symbols that may consist of a number of
possible states. Equivalent to bit-rate when the symbols only have two states (1 and 0). Measured in Baud.

BER

Bit Error Rate: A measure of transmission quality. The rate at which errors occur in the transmission of data bits

over a link. It is generally shown as a negative exponent, (e.g., 10-7 means that 1 in 10,000,000 bits are in error).

BISS Basic Interoperable Scrambling System: Non-proprietary encryption from EBU (Tech3290).

BW

Bandwidth: The transmission capacity of an electronic line such as (among others) a communications network,

computer bus, or broadcast link. It is expressed in bits per second, bytes per second or in Hertz (cycles per
second). When expressed in Hertz, the frequency may be a greater number than the actual bits per second,
because the bandwidth is the difference between the lowest and highest frequencies transmitted. High bandwidth
allows fast transmission or high-volume transmission.

Byte-mode

Each byte is delivered separately in the ASI Transport Stream, with stuffing data added between the Bytes to
increase the data rate to 270 Mbit/s. See DVB Document A010 rev. 1, Section B3.3, (ASI) Layer-2 Transport

Protocol.

CA

Conditional Access: The technology used to control the access to viewing services to authorised subscribers

through the transmission of encrypted signals and the programmable regulation of their decryption by a system
such as viewing cards.

CAT

Conditional Access Table: Part of the MPEG-2 Program Specific Information (PSI) data. Mandatory for MPEG-2

compliance if CA is in use.

C-Band

The portion of the electromagnetic spectrum, which spans the frequency range of approximately 4 GHz to 6 GHz.
Used by communications satellites. Preferred in tropical climates because it is not susceptible to fading.

CCIR See: ITU-R.
CCITT See: ITU-T.
Channel

A narrow range of frequencies, part of a frequency band, for the transmission of radio and television signals
without interference from other channels.
In the case of OFDM, a large number of carriers spaced apart at precise frequencies are allocated to a channel.

Channel Coding

A way of encoding data in a communications channel that adds patterns of redundancy into the transmission path
in order to improve the error rate. Such methods are widely used in wireless communications.

Chrominance

The colour part of a TV picture signal, relating to the hue and saturation but not to the luminance (brightness) of

the signal. In a composite-coded colour system, the colour information (chrominance, often referred to as

chroma) is modulated onto a high frequency carrier and added to the monochrome-format video signal carrying

the luminance (Y). In a component-coded colour system, the two colour-difference signals (R-Y)(B-Y) usually

referred to as C
added to the luminance

(digital) or PRPB (analogue), are used to convey colour information. When CRCB (PRPB) is

RCB

(Y), the complete picture information is conveyed as YCRCB (YPRPB).

Closed Captioning A TV picture subtitling system used with 525-line analogue transmissions.
CODE Create Once Distribute Everywhere.
Codec

The combination of an Enco

der and a complementary Decoder located respectively at the input and output of a

transmission path.

COFDM

Coded OFDM: COFDM adds forward error correction to the OFDM transmission consisting of Reed-Solomon

(RS) coding followed by convolutional coding to add extra bits to the transmitted signal. This allows a large number
of errors at the receive end to be corrected by convolutional (Viterbi) decoding followed by RS decoding.

Glossary

Compression

Reduction in the number of bits used to represent the same information. For the purposes of a broadcast system,
it is the process of reducing digital picture information by discarding redundant portions of information that are not
required when reconstituting the picture to produce viewing clarity. Compression allows a higher bite-rate to be
transmitted through a given bandwidth.

Compression System

Responsible for compressing and multiplexing the video / audio / data bit-streams, together with the authorisation
stream. The multiplexed data stream is then ready for transmission.

CRCB

Digital Colour difference signals. These signals, in combination with the luminance signal (Y), define the colour

and brightness of each picture element (pixel) on a TV line. See: Chrominance

CRC

Cyclic Redundancy Check: A mathematical algorithm that computes a numerical value based on the bits in a

block of data. This number is transmitted with the data and the receiver uses this information and the same
algorithm to ensure the accurate delivery of data by comparing the results of algorithm and the number received. If
a mismatch occurs, an error in transmission is presumed.

dB

Decibels: A ratio of one quantity to another using logarithmic scales to give results related to human aural or

visual perception. dB is a ratio whereas dBm, for example, is an absolute value, quoted as a ratio to a fixed point
of 0 dBm. 0 dBm is 1 mW at 1 kHz terminated in 600Ω. 0 dBmV is 1 mV terminated in 75Ω.

DCE

Data Communications Equipment: Typically a modem. It establishes, maintains and terminates a session on a

network but in itself is not the source (originator) or destination (end receiving unit) of signals (e.g. a computer, see

DTE). A DCE device may also convert signals to comply with the transmission path (network) format.

DCT

Discrete Cosine Transform: A technique for expressing a waveform as a weighted sum of cosines. Raw video

data is not readily compressible. DCT is not in itself a compression technique but is used to process the video data
so that it is compressible by an encoder. DCT processes the picture on an 8x8-pixel block basis, converting the
data from an uncompressible X Y form (as displayed by an oscilloscope) to a compressible frequency domain form
(as displayed by a spectrum analyser). Can be forward DCT or inverse DCT.

DDS Direct Digital Synthesiser.
Decoder

The unit containing the electronic circuitry necessary to decode encrypted signals. Some Decoders are separate
from the receiver but in satellite TV broadcasting, the term is often used interchangeably as a name for an
Integrated Receiver Decoder (IRD). The term IRD, or IRD / Decoder, is usually associated with satellite TV
broadcasting while Cable systems are based on Converters or on Set-Top Boxes / Converters.

Decoding Time-stamp

the system target Decoder.

DID Data Identifier.
Differential Coding Method of coding using the difference between the value of a sample and a predicted value.

that is, no intermediary cable or terrestrial network utilised.

DVB

Digital Video Broadcasting: A European project which has defined transmission standards for digital

broadcasting systems using satellite (DVB-S), cable (DVB-C) and terrestrial (DVB-T) medium, created by the

EP-DVB group and approved by the ITU. Specifies modulation, error correction, etc. (see EN 300 421 for satellite,

EN 300 429 for cable and EN 300 744 for terrestrial).

Glossary

Interframe Coding

Compression coding involving consecutive frames. When consecutive frames are compared, temporal redundancy

is used to remove common elements (information) and arrive at difference information. MPEG-2 uses B and P

frames, but since they are individually incomplete and relate to other adjacent frames, they cannot be edited

independently.

Intraframe Coding

Compression coding involving a single frame. Redundant information is removed on a per frame basis. All other

frames are ignored. Coding of a macroblock or picture that uses information only from that macroblock or picture.

Exploits spatial redundancy by using DCT to produce I frames; these are independent frames and can be edited.

IP

Internet Protocol: The IP part of TCP/IP. IP implements the network layer (layer 3) of the protocol, which contains

a network address and is used to route a message to a different network or sub-network. IP accepts packets from

the layer 4 transport protocol (TCP or UDP), adds its own header to it and delivers a datagram to the layer 2 data

link protocol. It may also break the packet into fragments to support the Maximum Transmission / Transfer Unit

(MTU) of the network.

I-picture; I-frame

Intracoded Picture/Frame: A picture / frame, which is coded using purely intracoding with reference to no other

field or frame information. The I frame is used as a reference for other compression methods.

IPPV Impulse Pay Per View: One-time events, purchased at home (on impulse) using a prearranged SMS credit line.
IRD

Integrated Receiver Decoder: The Receiver with an internal MPEG Decoder, which is connected to the

subscriber’s TV. The IRD is responsible for receiving and de-multiplexing all signals. The unit receives the

incoming signal and if CA is active, decodes the signal when provided with a control word by the viewing card.

Domestic IRDs are also known as Set-Top Units or Set-Top Boxes.

IRE

Institute of Radio Engineers: No longer in existence but the name lives on as a unit of video amplitude

measurement. This unit is 1% of the range between blanking a peak white for a standard amplitude signal.

ISDN

Integrated Services Digital Network: The basic ISDN service is BRI (Basic Rate Interface), which is made up of

two 64 kbit/s B channels and one 16 kbit/s D channel (2B+D). If both channels are combined into one, called

bonding, the total data rate becomes 128 kbit/s and is four and a half times the bandwidth of a V.34 modem

(28.8 kbit/s).

The ISDN high-speed service is PRI (Primary Rate Interface). It provides 23 B channels and one 64 kbit/s D

channel (23B+D), which is equivalent to the 24 channels of a T1 line. When several channels are bonded together,

high data rates can be achieved. For example, it is common to bond six channels for quality videoconferencing at

384 kbit/s. In Europe, PRI includes 30 B channels and one D channel, equivalent to an E1 line.

their information when power is removed. Stores the default configuration parameters set by the user.

OFDM

Orthogonal FDM: A modulation technique used for digital TV transmission in Europe, Japan and Australia; more

spectrally efficient than FDM. In OFDM, data is distributed over a large number of carriers spaced apart at precise

frequencies. The carriers are arranged with overlapping sidebands in such a way that the signals can be received

without adjacent channel interference.

OPPV Order ahead Pay Per View: An advance purchase of encrypted one-time events with an expiry date.
OSD

On-screen display: Messages and graphics, typically originating from the SMS, and displayed on the subscriber’s

TV screen by the IRD, to inform the subscriber of problems or instruct the subscriber to contact the SMS.

Packet

A unit of data transmitted over a packet-switching network. A packet consists of a header followed by a number of

contiguous bytes from an elementary data stream.

PAL

Phase Alternating Line: A colour TV broadcasting system where the phase of the R-Y colour-difference signal is

inverted on every alternate line to average out errors providing consistent colour reproduction.

PAT

Program Association Table: Part of the MPEG-2 Program Specific Information (PSI) data and is mandatory for

MPEG-2 compliance. The PAT points (maps) to the PMT.

PCM

Pulse Code Modulation: A process in which a signal is sampled, each sample is quantised independently of

other samples, and the resulting succession of quantised values is encoded into a digital signal.

PCR Program Clock Reference: A time-stamp in the transport stream from which the Decoder timing is derived.
PDC

Program Delivery Control: A Teletext service allowing simple programming (i.e. VideoPlus) of VCR recording

times. If the desired program is rescheduled, PDC updates the programming information in the VCR.

Pel

Picture Element: Also known as a pixel. The smallest resolvable rectangular area of an image either on a screen

or stored in memory. On screen, pixels are made up of one or more dots of colour. Monochrome and grey-scale

systems use one dot per pixel. For grey-scale, the pixel is energised with different intensities, creating a range

from dark to light (a scale of 0-255 for an eight-bit pixel). Colour systems use a red, green and blue dot per pixel,

each of which is energised to different intensities, creating a range of colours perceived as the mixture of these

dots. If all three dots are dark, the result is black. If all three dots are bright, the result is white.

PES

Packetised Elementary Stream: A sequential stream of data bytes that has been converted from original

elementary streams of audio and video access units and transported as packets. Each PES packet consists of a

header and a payload of variable length and subject to a maximum of 64 kbytes. A time-stamp is provided by the

MPEG-2 systems layer to ensure correct synchronisation between related elementary streams at the Decoder.

comparing its rotational position (phase) with another rotating object as in the case of a sine wave or other

repeating signal. This type of control system can synchronise not only the speed, but also the angular position of

two waveforms that are not derived from the same source.

PMT

Program Map Table: Part of the MPEG-2 Program Specific Information (PSI) data and is mandatory for MPEG-2

compliance. Each service has a PMT, which lists the component parts (elementary streams of video, audio, etc.)

for the various services being transmitted.

P-picture/P-frame

A picture / frame produced using forward prediction. It contains predictions from either previous I frames or

previous P frames. The P frame is used as a reference for future P or B frames.

ppm Parts per million.
PPV

Pay Per View: A system of payment for viewing services based on a usage / event basis rather than on on-going

subscription. Subscribers must purchase viewing rights for each PPV event that they wish to view. PPV events

may be purchased as IPPV or OPPV.

Program

PC - A sequence of instructions for a computer.

TV - A concept having a precise definition within ISO 13818-1 (MPEG-2). For a transport stream, the timebase is

defined by the PCR. The use of the PCR for timing information creates a virtual channel within the stream.

SFN

Single Frequency Network: The SFN technique allows large geographic areas to be served with a common

transmission multiplex. All transmitters in the network are synchronously modulated with the same signal and they

all radiate on the same frequency. Due to the multi-path capability of the multi-carrier transmission system

(COFDM), signals from several transmitters arriving at a receiving antenna may contribute constructively to the

total wanted signal. The SFN technique is not only frequency efficient but also power efficient because fades in the

field strength of one transmitter may be filled by another transmitter.

SI

Service Information: Digital information describing the delivery system, content and scheduling (timing) of

broadcast data streams. DVB-SI data provides information to enable the IRD to automatically demultiplex and

decode the various streams of programmes within the multiplex.

C.1 LCD Menus

C.1.1 Using the Menus

Detailed description of the use of menus is given in Chapter 3, Operating
the Equipment Locally.

C.1.2 Menu Descriptions

This annex describes the front panel LCD menus.
When the unit is first powered up, it progresses through a series of

start-up pages on the LCD display.
The menu is created in a tree structure, where each branch may contain

items, new branches, or both.
An item is viewed as an information string on the left side of the LCD, with

an editable or selectable item on the right side, or an information string.
A path to a new sub branch is viewed as an information string on the left

side of the LCD, where the string ends with a “>” character. The “>”
symbolises the arrow key you have to press, to enter the submenu.

The TV audio setup menu allows the user to configure the output level and modulation of the first audio
channel.

Stereo, mono, transp(arent) or ProLog selectable.
The modulation of the audio depends both on the modulation used on the encoder
side, and on the decoder side. Table C.12 describes, in more detail, the modulator
option shown in Table C.11 under TV audio setup.

Table C.12 lists what is output on the decoder, in correlation to the modulator
setting, and what is sent from the Encoder.

Enables digital audio output. “Off”, ”AC-3” or “Linear” selectable.
(2 stereo chnl models only)

The Audio2 setup menu is virtually the same menu as the TV audio setup menu, only that it affects the
secondary audio output of the Decoder, not the primary. For information on how the parameters affect
the output, refer to TV audio setup above.

The PTS setup menu, allows the user to configure a offset for the audio, in relation to the PTS
(Presentation Time Stamp). This is useful for correcting lipsync generated on the encoder (or earlier)
stage in the transmission process.

The factory adjustment menu contains parameters (video gain, chroma gain, audio level fine tuning),
that is preset to the correct level when shipped from TANDBERG Television.

However, should there be a need to change these values, you may call TANDBERG Television
support, at the number shown in the Preliminary pages of this manual, to obtain the necessary PIN to
access these menus.

Table C.12 describes, in more detail, the modulator option shown in Table
C.11 under TV audio setup.

Table C.12: Audio Modulation Res ults

Audio source Modulator output

Stereo Mono Transparent
Left Right Left Right Left Right
Stereo (or joint stereo) L R L+R L+R L R
Dual Channel No.1 (L)

No. 2 (R)
Single Channel (mono) 1 1 1 1 1 1

The Left output and Right output columns refer to the output at the left
and right audio connector, respectively. “L” and “R” refer to the content of
the left and right audio signal present in a stereo 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), or 1 for a mono PID.

As seen from the table, Dual Channel PIDs will only provide both channels
to the user if modulation is set to “transparent”. This could for instance be
very useful for a two language service, where each language is sent as a
mono component in a dual channel PID. In both the stereo and mono
configurations, a dual channel PID will only provide one of the audio
channels to the users.

1 1 1 1 1 2
2 2 2 2 2 1

This channel is selected to match the “Aud Lang” setting set up in the TV
Components Menu (see Table C.6). If the language setting does not match
any of the two audio components in the dual channel stream, the first one
will be selected and decoded.

Alarm Setup Menu

The alarm setup menu, is a hub-menu, where the submenus contain all
the configurable alarm parameters, sorted into groups. The alarm
parameters may be configured into three levels of severity; alarm (A),
warning (W), or ignore (-).

device. 1200, 2400, 4800, 9600, 19200, 38400, 57600 and
115200 baud selectable.

The LS data menu configures the parameters for the output of RS-232 data,
fetched from the transport stream.

Off, manual or diagnostic selectable. In off mode, no data is
output on the port. In manual, the selected PID is output on the
port. In diagnostic, the diagnostic information from the TT1220
is output on the port.

Selects the PID that is output on the port if “mode” is set to
manual.

Shows the filling of the RS-232 buffer. If this buffer cycles up to
100% constantly, it is likely that you are not getting all the data
on the output, due to buffer overruns.

NOTE…

TANDBERG Television’s remote control or software upgrade software requires the use of a
null-modem (crossed) RS-232 cable, not a straight cable.

CAUTION…

When software upgrading the TT1220 via RS-232 and the TANDBERG Television software upgrader

(UPGRADE.EXE), it is important that the baud rate is set to 38400, the data bits to 8, the stop bits to 1,

the parity to none, and the flow control to none. If this is not the case, the UPGRADE software might fail

to work.

The RS-232 data output cannot exceed the data rate configured in the
communication menu. If the outgoing data rate is higher, information will
be dropped in an unpredictable fashion.

The transmitted PID’s contents should have a lower rate than 115200
bit/s, since this is the maximum output rate. If the rate is higher, burst
mode can be used, as explained in the Output Menu Section.

Port Settings Menu

The port settings menu contains the controls for the physical output of the
LS data, including baud-rate etc.

The settings configured here, need to match the settings on the device set
