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.

Introduction

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.

Introduction
1.4.2 What the Decoder Does
The ASI interface is 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.

1.5 Control Modes
1.5.1 Introduction
The IRD is designed for unattended operation. Once set up, the unit
requires no further attention except to ensure the fan is working. There are
up to three control modes associated with the Receiver (dependent upon
options fitted). The unit remains in the chosen control mode until another
mode is requested.
NOTE…
Local (Front Panel) Control is the factory default if TANDBERG Director is not installed.

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 Figure 1.7. Information on the use
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

(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:
• Basic Interoperable Scrambling System (BISS), Mode 1 and Mode E
only.
• Remote Authorisation System (RAS) and RAS 2
• TANDBERG Director
• DVB Common Interface
Page 3-14 Reference Guide: TT128x High Definition Professional Receiver/Decoder
ST.RE.E10141.5
Page 51
Operating the Equipment Locally
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 options fitted on the same unit.
3.8.2 Basic Interoperable Scrambling System (BISS)
(Menu 4.4)
BISS Mode 1 is similar 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.
3.8.3 Remote Authorisation System (RAS) (Menu 4.1)
RAS has two levels of operation: FIXED KEY MODE and DSNG KEY MODE.
FIXED KEY MODE has a fixed control word to encrypt the data in the
transport stream.
DSNG KEY MODE is used for fixed head-end systems. 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.
3.8.4 TANDBERG Director (Menu 4.3)
There is a single slot on the IRD pack panel to allow the insertion of a
Smart Card for the TANDBERG Director system. Director functionality
includes Conditional Access, over-air software download and over-air
control.
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.
3.8.5 DVB Common Interface (Menu 4.3)
There is a single slot on the IRD pack panel to allow the insertion of a DVB
Common Interface (CI) Conditional Access module (CAM) and related
conditional access card.
Other than the insertion of the CAM and Access card, no specific set-up is
required at the IRD for the DVB Conditional Access.

4.1 Remote Control
4.1.1 Introduction
The IRD can be remotely controlled in a variety of ways. The basic control
methods are:
• TANDBERG Device Controller (TDC)
• Third-party application using TANDBERG SNMP MIB protocol
• Third-party application using Alteia remote control protocol
(RS-232/RS-485)
• TANDBERG Director (over-air)
Common for all control methods is that the IRD 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

OAC Lockout
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 Personal Identification Number
(PIN) may be entered through the keypad.
Press the down pushbutton and select
‘DIRECTOR NCP’.
The settings should be set to match the external control host.
CAUTION…
TANDBERG Television Customer Services Help Desk will not be able to provide you with the Local

5.1 Introduction
There are two Front Panel LEDs that indicate the status of the IRD. These
are used to indicate 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.
Alarm LED
Alarms
Figure 5.1: Front Panel LEDs
5.3 ALARM LED
The IRD 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.
This LED provides 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 conditions during normal operation: (if not masked,
see Menu 6, Annex C, Menus):
• No transport stream
Lock LED
• Video not running
• Audio 1 not running
• Audio 2 not running
• Unit temperature

Error Correction code are appended to the packet before transmission, bringing the packet length to 204 bytes.
The 16 bytes are used at the receiving end to correct any errors. Up to eight corrupted bytes can be corrected.
RLC
Run Length Coding: Minimisation of the length of a bit-stream by replacing repeated characters with an
instruction of the form ‘repeat character x y times’.

STB
Set-Top Box: A box that sits on top of a television set and is the interface between the home television and the
cable TV company. New technologies evolving for set-top boxes are video-on-demand, video games, educational
services, database searches, and home shopping. The cable equivalent of the IRD.
STT System Time Table (ATSC).
SFN
Single Frequency Network: The SFN technique allows largegeographic 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.
Specified in ISO/IEC 13818[1]. (DVB)
Single Packet Burst Mode
A burst of ASI bytes (either 188 or 204, depending on packet length) is contiguously grouped into an MPEG-2
Transport Stream packet. Stuffing data is added between the packets to increase the data rate to 270 Mbit/s. See
DVB Document A010 rev. 1, Section B3.3, (ASI) Layer-2 Transport Protocol.
Smart Card
A plastic card with a built-in microprocessor and memory used for identification, financial transactions or other
authorising data transfer. When inserted into a reader, data is transferred to and from the host machine or a
central computer. It is more secure than a magnetic stripe card and it can be disabled if the wrong password is
entered too many times. As a financial transaction card, it can be loaded with digital money and used in the same
way as cash until the balance reaches zero. The file protocol is specific to its intended application.

households of a building or group of buildings, typically used to refer to an apartment block.
SMPTE Society of Motion Picture and Television Engineers.
SMS
Subscriber Management System: A system which handles the maintenance, billing, control and general
supervision of subscribers to conditional access technology viewing services provided through cable and satellite
broadcasting.
An SMS can be an automatic (e.g. Syntellect) system where subscribers order entitlements by entering
information via a telephone. Alternatively, an SMS can be a manual system, which requires subscribers to speak
with an operator who then manually enters their entitlement requests. Some systems support multiple SMSs.
Information repetition due to areas of similar luminance and/or chrominance characteristics within a single frame.
Removed using DCT and Quantisation (Intra-Frame Coding).
Data tables are used to assign fewer bits to the most commonly occurring events, thereby reducing the overall
bit-rate. Removed using Run Length Coding and Variable Length Coding.

Temporal Redundancy
Information repetition due to areas of little or no movement between successive frames. Removed using motion
estimation and compensation (Inter-Frame Coding).
Time-stamp
A term that indicates the time of a specific action such as the arrival of a byte or the presentation of a presentation
unit.
TOT
Time Offset Table: This optional SI table supports the use of local offsets as well as the UTC time/date
combination.
The purpose of the table is to list by country the current offset from UTC and the next expected change to that
offset (to track when daylight saving occurs).
The offset resolution is to within 1 minute over a range of ±12 hours from UTC.

Technical Specification
B.1.4 HD SDI
HD SDI output supports:
• Embedded Decoded Audios
• Closed Captioning (EIA 708B)
• VITC
B.2 Audio Decoding and Output Stage
B.2.1 General
The IRD is capable of simultaneously decoding two PES streams of audio
from the transport stream. Each of the decoders is identical in operation,
but act completely independently of the other, with the following
exceptions:
• Both decoders must be decoding channels that have the same
sampling rate
• Both decoders are not required to simultaneously decode the same PES
stream
Each channel supports extraction of four types of coded audio from the
Transport Stream as follows:
Audio component selection is automatic or may be specified from the User
Interface or remote interfaces. The IRD automatically detects the audio
type of the selected audio component and applies the appropriate
algorithm. Audio component selection is based on the position of the
component descriptor in the PMT. Audio 1 takes the first component,
Audio 2 the second. These may be overridden by selecting User-specified
component PIDs.
B.2.2 MPEG Audio
The IRD supports decoding of MPEG audio as follows:
• Compression layers: MPEG-1 layers I and II
• Sampling rates (kHz): 32, 44.1, 48
• Maximum compressed data rate: 384 kbit/s (layer II)
B.2.3 Dolby Digital AC-3 Audio
The IRD is able to decode and output the primary stereo pair of a Dolby
Digital AC-3 encoded audio stream. When there is data encoded on the
audio surround channels, the Decoder applies downmixing, so that either a
surround encoded stereo pair (LtRt downmix) or a conventional stereo pair
(LoRo downmix) is available at the output.
The IRD is not able to decode and output all 5.1 channels individually as
separate channels.
Page B-4 Reference Guide: TT128x High Definition Professional Receiver/Decoder
ST.RE.E10141.5
Page 97
It is possible to output the compressed Dolby Digital stream from the
digital audio output, allowing it to be decoded to 5.1 channels by an
external Decoder.
Sampling rates (kHz): 32, 44.1, 48
Maximum compressed data rate: 640 kbit/s
NOTE…
Support for Dolby Digital decoding requires approval and licensing from Dolby. The compressed Dolby
Digital stream is not embedded on the SDI output.
B.2.4 Linear Audio
The IRD is able to receive audio data in the form of linear PCM digital audio
data, up to 20 bits in resolution, and makes it available for output as either
analogue or digital audio.
B.2.5 DTS Audio
The IRD is able to detect DTS audio Modes 1, 2 or 3. DTS audio is
presented in AES format at the digital audio output.
Technical Specification
B.3 Audio Output Format
B.3.1 General
The IRD provides an independent stereo pair output for each audio
channel. Analogue audio is always output and the following digital audio
formats can be chosen from the User Interface and remote control
interfaces:
• AES3 format
• Dolby Digital (AC-3) compressed format
Digital Audio embedded into the HD Serial Digital Video Output is always
output using the DIDs for channel mapping specified at the user interface.
B.3.2 Analogue Audio
The IRD supports level control of the audio outputs. Independent control of
each output of each stereo pair is provided via the User Interface and
remote interfaces.
Audio output connector type: 2 x 9 way female D-type
Output level: +18 dBm nominal clipping level. Selectable in range +12 to
+24 dBm.
Output impedance: 50 Ω (nominal).

Noise RMS -65 dB
Phase 40 Hz to 15 kHz ±2°
Lip sync delay Depends on synchroniser configuration ±5 ms
B.3.3 Audio Routing
The IRD supports the following routing of audio signal:
• STEREO (Channel 1 left, Channel 2 right)
• MIXED TO BOTH (Channel 1 and 2 on left and right)
• LEFT TO BOTH (Channel 1 on left and right)
• RIGHT TO BOTH (Channel 2 on left and right)
When the input signal is STEREO, the Audio digital output format will
always be STEREO.
Where a dual mono service is available, it is possible to configure the
output as MIXED TO BOTH, LEFT TO BOTH and RIGHT TO BOTH.
B.3.4 Lip Sync
The audio at the output remains synchronous to the decoded video by
default (i.e. where both video and audio streams are available from the
same service). In such circumstances the video and audio streams share
the same PCR.
The lip sync error (delay from presentation of video until presentation of
audio) introduced by the Receiver is in the range of ±5 ms.
The lip sync delay between stereo pair 1 and 2 is ±2 ms because the PTS
will be presented independently for each pair.
When using frame sync the lip sync error is up to 40 ms due to audio
frame skip and repeats.
