ST.RE.E10100.1

Remote Control

An RJ-45 Ethernet connector connects to a PC or network switch to provide
a network connection for use with SNMP control.

Frame Synchronisation

A BNC connector accepts a composite video input to which the video
output timing can be synchronised.

1.2.3 Outputs

Transport Stream Outputs

· Two BNC connectors output ASI Transport Streams with a maximum

data rate of 160 Mbit/s.

Video Outputs

· Two analogue composite video outputs carried on BNC connectors.

· Two digital video outputs carried on BNC connectors.

Audio Outputs

· Two 9-way D-type, female connectors decode two PES streams of

audio from the Transport Stream. The audio outputs simultaneous
analogue and digital. The digital mode can be changed via the user
interface.

Introduction

Data Output

· RS-232 asynchronous low-speed data output carried on a 9-way,

D-type, female connector.

· RJ-45 high-speed data over Ethernet output (option).

· RS-422 synchronous high-speed data output carried on a 9-way

Reference Guide: TT1260 Contribution Receiver Page 1-7
ST.RE.E10100.1

Introduction

1.2.4 Conditional Access and Scrambling

The transport stream received by the IRD may be encrypted. The CA
system is used to decrypt the required components of the transport
stream so that they can be decoded.

The following Conditional Access and Scrambling options are available for
the TT1260 range of Satellite Receivers and Decoders:

· No Conditional Access

· Basic Interoperable Scrambling System, BISS Mode 1 and Mode E only.

· TANDBERG Director

· Remote Authorisation System (RAS) 1 and 2

· Signal Protection

· DVB Common Interface

BISS (as specified in EBU Tech 3292 May 2002) is standard on all
Receivers/Decoders.
The different CA options can be combined, for instance:

· TANDBERG Director, RAS and BISS (however, streams with mixed CA

are not supported)

However, it is not possible to have both DVB Common Interface and
TANDBERG Director on the same unit.

When the CA system uses a smart card or Common Interface Module,
access by the user is via the back panel of the IRD.

1.3 The Satellite Receiver

1.3.1 Typical Satellite System

The TT1260 Satellite Receiver is a component of the MPEG-2/DVB
compliant range of TANDBERG Television equipment. It is designed for use
by broadcasters and distributors of video, audio and data services over
satellite.

1.3.2 Input Connections

The Satellite Receiver interfaces directly to Low-Noise Block (LNB) and
accepts an intermediate frequency (IF) input in the band 950 - 2150 MHz

(L-band) for operation in the specified symbol-rate range (see Annex B,
Technical Specification). The unit can provide dc power and polarisation

switching to the LNB.

1.3.3 What the Satellite Receiver Does

The Receiver can be tuned to a specified satellite channel frequency and
polarisation. The input is down-converted via a Low-Noise Block (LNB) to
provide an L-band input to the Receiver. The front-end tuning is
microprocessor controlled with a frequency synthesised local oscillator. A
software tuning and acquisition algorithm resolves translation errors
(mainly due to the LNB).

The signal is then passed to a demodulator that recovers the signal using
soft-decision decoding. The resulting stream is Reed-Solomon decoded and
descrambled to provide inputs to the Decoder circuit. The received channel
may contain multiple services, therefore the Receiver’s demultiplexer is
configured to select a single video service and other audio/data
components and present them at the output.

operation.

Reference Guide: TT1260 Contribution Receiver Page 1-11
ST.RE.E10100.1

Introduction

1.4.3 What the Decoder Does

The ASI interfaces are used to present the transport stream in the format
required by the internal Decoder circuitry. At this point, the operation of
the unit is the same as the Satellite Receiver.

The Decoder can be used to receive an input signal from a Public Telecom
Network via a Network Adapter Unit (NAU). No error correction is
supported at the input of the unit so a level of Quality of Service should be
negotiated with the Telecom Network Provider.

The Decoder is configured to select a single video service and other
audio/data components from the multiple services on the incoming
transport stream and present them at the output.

RS-232/RS-485 Port

The unit enters this state when the RS232/RS485 REMOTE port receives
a configuration change command or the Remote control mode is selected
in the System Menu (#6); see Section C.9, Sy stem Menu. The baud-rate

of the network control is dependent upon the selected protocol. Local
commands are ignored when the unit is in Remote Control mode.

Network

The unit will operate in a similar manner when the Network port is enabled

to receive SNMP commands. The TT1260 must have its IP Address and
Subnet Mask configured to conform to the controlling network.

NAVIGATE

1.5.4 TANDBERG Director NCP Control Mode

With the VideoGuard Conditional Access software installed and a valid
Smart Card inserted, a TT1260 Satellite Receiver can be put into Director
NCP control mode.

NOTE…

Front Panel mode is the factory default for Receivers used in a TANDBERG Director system. To switch

to Director NCP mode refer to Section 3.9, Setting Up System Parameters.

All Front Panel and Serial Remote commands are ignored except the
operating mode. The TT1260 can be put into a local lockout condition.
When in this condition, there are two ways to recover control:

· Cancelling the local lockout using an over-air command.

· Entering a PIN number via the Conditional Access menu in

Menu #4.3.6 (see Section C.7.4, Director Menu).

Either of these actions will put the Receiver out of local lockout mode.

Introduction

1.6 Guided Tour

1.6.1 Construction

The IRD is constructed using a screened self-ventilated modular system.
All operational inputs and outputs are via rear-panel connectors. The unit
may be operated freestanding or mounted in a 19-inch rack.

1.6.2 Front Panel Controls

The physical interface for the Front Panel consists of an alphanumeric LCD
display, pushbuttons, and status LEDs that are used to set up and monitor
the unit. The general layout is shown in

of these controls is given in Chapter 3, Operating the Equipment Locally.
User input is via six pushbuttons comprising four cursor pushbuttons: Left,

Right, Up, and Down; and two edit control pushbuttons: Edit and Save.
Each pushbutton has an integral green LED except Save, which has an

integral red LED. When lit these LEDs indicate to the user which
pushbutton is currently active.

Automatic repeat following an initial delay period is implemented for the

Left, Right, Up, and Down pushbuttons in software.

Figure 1.8. Information on the use

Figure 1.8: Front Panel Controls

1.6.3 Front Panel LEDs

Figure 1.8 shows the location of the LEDs on the front panel. The LEDs

indicate the equipment status as follows:

The red ALARM LED is used to indicate an IRD fault condition, e.g. a

missing or faulty input signal. It should be off for correct operation,
although it may be lit briefly during power-up.

The green LOCK LED is used to indicate that the IRD is locked to a

transport stream when lit, and indicates correct conditions and correct
system functioning.

2.8.1 General

It is strongly recommended that the terminal marked

to a site Technical Earth before any external connections are made and the equipment is powered. This

limits the migration of stray charges.

CAUTION...

at the rear panel of the equipment is connected

All signal connections are made vi a the rear panel. A typical rear panel is
shown in

Figure 2.4. The connections are also shown schematically in

Figure 2.5, and a full technical specification is given in Annex B.

The Receiver provides a flexible transport stream input interface. It is not a
requirement for the equipment to support more than one optional input
type in any one configuration.

The status information appropriate to each input type is avai lable to the
user via the User Interface, and also via the remote control interfaces.

2.8.5 Frame Synchronisation

A BNC socket is used by the Decoder to frame lock to an
external video source (NTSC or PAL). The frame
information is input as a composite signal, with or
without active video. The user can offset the
synchronisation to the video output by ±8 lines of the
reference signal, with a resoluti on of 1 p ixel of the
reference signal. Lip sync error introduced by the
Receiver is in the range -10 ms to +30 ms. This implies
audio frame skip and repeat may occur.

The video and audio can be synchronised to an analogue
studio reference signal. This supports both 625 and 525
frame locking.

This Frame Sync is activated through the Service menu
(Menu 3).

3.8 Setting Up the Conditional Access/Scrambling (Menu #4)

3.8.1 Introduction

Menu #4 allows the status and configuration of the Conditional Access
(CA) module to be checked. The structure and content of this group
depends on the CA system. The available CA options are as follows:

· No Conditional Access

· Basic Interoperable Scrambling System (BISS), Mode 1 and Mode E

only.

· Remote Authorisation System (RAS 1 and RAS 2)

· TANDBERG Director

· DVB Common Interface

BISS (as specified in EBU Tech 3292 May 2002) is standard on all units. It
is not possible to have both DVB Common Interface and TANDBERG
Director on the same unit.

3.8.2 Remote Authorisation System (RAS) (Menu #4.1)

RAS has two levels of operation: FIXED KEY MO DE and DSNG KEY MO DE.
FIXED KEY MODE has a fixed control word to encrypt the data in the

transport stream.
DSNG KEY MODE allows the user to specify the current session word so

that it can be matched with a live DSNG transm ission. In a RAS 2 system,
each receiver needs to be enabled to decrypt the Transport Stream via the
RAS II headend control system. Its main functionality is:

· Over-air addressing of Receivers for authorisation/de-authorisation to

decrypt the transmission.

· Group operation for authorisation/de-authorisation.

· Periodic control word changes during transmission.

Menu #4.1 allows fixed/dsng selection and allows entry of the dsng key.

3.8.3 TANDBERG Signal Protection (Menu #4.2)

The TT1260 can be enabled with TANDBERG Signal Protection, which is a
non-smart card based signal protection system. Contact TANDBERG
Television sales desk for more details.

Menu #4.2 allows this protection system to be enabled/disabled.

3.8.4 TANDBERG Director (Menu #4.3)

There is a single slot on the TT1260 rear panel to allow the insertion of a
Smart Card for the TANDBERG Director system. The TANDBERG Director
system offers premium functionality including Conditional Access, Over-Air
software download and Over-Air Control. Please refer to the TANDBERG
Director user manual for more details.

Other than the insertion of the Smart Card, no specific set-up is required
at the IRD for the Conditional Access or software download. For over-air
control (NCP) see Chapter 4, Operating the Equipment Remotely.

ST.RE.E10100.1

Operating the Equipment Locally

3.8.5 Basic Interoperable Scrambling System (BISS) (Menu #4.4)

BISS Mode 1 is simil ar to RAS in that it uses a fixed control word to
encrypt the data in the transport stream. Unlike RAS, the scrambling
algorithm is non-proprietary, using the DVB Common Scrambling
Algorithm to allow interoperability with other manufacturers’
encoding/scrambling equipment.

Menu #4.4 allows selection of BISS Mode 1 or Mode E operation and allows
the fixed key to be entered. Menus #4.4.1 and #4.4.2 allow user injected
box ids to be entered.

3.8.6 DVB Common Interface (Menu #4)

There is one slot on the rear of the unit, to allow the insertion of a DVB
common interface (CI) conditional access module (CAM). This CAM module
will host the Conditional Access (CA) card for the CA system. The CAM and
the CA card needs to be manufactured to host the same CA system. Please

· Third-party application using Alteia remote control protocol

(RS-232/RS-485)

· TANDBERG Director (over-air)

· Web Browser

Common for all control methods is that the TT1260 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 in the TT1260 Remote Control
Specification ST.TS.E10100. This protocol is not described, or intended to
be in the scope of this manual.

5.1 Introduction

There are two Front Panel LEDs that indicate the status of the TT1260.
There is also one summary alarm relay and six additional alarm relays
(optional). These are used to ind icate abnormal performance of the unit.

5.2 Location of the Alarm and Lock LEDs

The red ALARM LED is used to indicate an equipment fault condition, for
example a missing or faulty input signal. It should be off during correct
operation, although it may be lit briefly during power-up.

The green LOCK LED is used to indicate that the equipment is locked to a
transport stream when lit, and indicates correct conditions and correct
system functioning.

Figure 5.1: Front Panel LEDs

5.3 ALARM LED and Summary Relay

The TT1260 supports a summary alarm signal that is active when one or
more of the individual monitored alarm conditions are active. It allows
masking of unwanted alarm conditions so that they do not contribute to
the summary alarm. Configuration of alarms is via the Front Panel and
remote control interfaces. The state of the summary alarm is reflected by
the ALARM LED on the front panel where red represents an alarm, and off
represents no alarm. The summary alarm relay is active when the al arm
LED is active.

These indicators provide a high-level indication of an alarm within the unit.
The alarm list depends on the unit model. The unit continuously monitors
for the following alarm conditi ons during normal operation: (if not masked,
see Menu #5, Annex C, Menus):

· No transport stream

· Video not running

· Audio 1 not running

· Audio 2 not running

Reference Guide: TT1260 Contribution Receiver Page 5-3
ST.RE.E10100.1

Alarms

It is possible to signal additional alarms depending on the
Transport Stream input type and optional functionalit y in the unit.

Satellite inputs:

· Bit Error Rate (BER) above (programmable) threshold.

· Modulation Error Ratio (MER) above (programmable) threshold.

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.

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

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.

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.

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).

Basic Interoperable Scrambling System: Non-proprietary encryption from EBU (Tech3290).
Basic Interoperable Scrambling System: with Encrypted keys.

The rate of transfer of digital data when the data comprises two logic states, 1 and 0. Measured in bit/s.

An 8-row by 8-column matrix of luminance sample values, or 64 DCT coefficients (source, quantised, or
dequantised).

A collection of services (TV, radio, and data, or any combination of the three) grouped and sold together, and
identified in the SI as a group. A single service may be in several bouquets.

Bi-directionally Predictive Coded Picture/Frame: A picture that is coded using motion-compensated prediction

from previous I or P frames (forward prediction) and/or future I or P frames (backward prediction). B frames are not
used in any prediction.

Binary Phase Shift Keying: A data modulation technique.
A memory store used to provide a consistent rate of data flow.
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.

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.

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.

compliance if CA is in use.

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.

See: ITU-R.
See: ITU-T.

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.

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.

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

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

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.

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.

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.

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
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.

Cable Virtual Channel Table (ATSC).
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.

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.

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.

Direct Digital Synthesiser.

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.

A field that may be present in a PES packet header that indicates the time that an access unit is to be decoded in
the system target Decoder.

Data Identifier.

Method of coding using the difference between the value of a sample and a predicted value.
Dual In Line: The most common type of package for small and medium scale integrated circuits. The pins hang

vertically from the two long sides of the rectangular package, spaced at intervals of 0.1 inch.
Deutsches Institut für Normung: German Standards Institute.
Formerly AC-3. An audio coding system based on transform coding techniques and psychoacoustic principles.
The part of the satellite communications circuit that extends from the satellite to an Earth station.
The process by which the frequency of a broadcast transport stream is shifted to a lower frequency range.
Differential Pulse Code Modulation: An audio digitisation technique that codes the difference between samples

rather than coding an absolute measurement at each sample point.

Digital Satellite News-Gathering.
Digital Signal Processor.
Data circuit Terminating Equipment: A communications device that originates (is the source) or is the end

receiving unit (destination) of signals on a network. It is typically a terminal or computer.

Direct To Home. The term used to describe uninterrupted transmission from the satellite directly to the subscriber,

that is, no intermediary cable or terrestrial network utilised.

Digital Theater Systems: A motion picture digital sound system.
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,

International Electrotechnical Committee.
Intermediate Frequency: Usually refers to the 70 MHz or 140 MHz output of the Modulator in cable, satellite and

terrestrial transmission applications.

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.

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.

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.

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.

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

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.
