Introduction to the Basic Encoder
E5714
The satellite modulator within the E5714 supports QPSK modulation in
accordance with EN 300 421 (DVB-S). It provides a main and monitoring
IF Output. The IF frequency can be tuned between 50 MHz and 90 MHz, or
950 – 1750 MHz on the E5714 L-band.
E5740/E5760
The satellite modulator fitted within the E5740 is capable of QPSK
modulation in accordance with EN 300 421 (DVB-S), and is also capable of
8PSK and 16QAM modulation in accordance with EN 301 210 (DVB-DSNG).
It is available in two variants. One provides an IF output tuneable in the
range 50 MHz to 180 MHz. The other provides an L-band output tuneable
in the range 950 MHz to 1750 MHz.

Equipment
Figure 1.4: Typical DENG System Configuration
The OFDM modulator fitted in the E5750 takes the Encoder’s output
transport stream, and uses Coded Orthogonal Frequency Division
Multiplexing (COFDM) to spread the data over 1705 carriers (2k mode) or
6817 carriers (8k mode). This means that relatively low data rates can be
used on each carrier frequency, and any multipath effects (ghosting) which
occur affects only a small amount of data.
The carriers are closely spaced so that their sidebands overlap, but due to
the orthogonal relationship between carrier frequencies they do not
interfere with each other. This makes the system spectrally efficient.
Noise, multipath effects, co-channel interference and other impairments
can cause some bits to be received in error. Therefore, Forward Error
Correction (FEC) consisting of Reed-Solomon (RS) coding followed by
convolution coding is used 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.
2
Five convolutional rates are available: ½,
/3, ¾, 5/6 and 7/8. These provide
different compromises between bit-rate and ruggedness.
The modulation scheme used on each carrier can either be QPSK, 16QAM,
or 64QAM. These also provide different compromises between bit-rate and
ruggedness, QPSK being the most rugged.
Four guard intervals are available
1
/32, 1/16, 1/8, and ¼. These are used to
reduce the effects of intersymbol interference at the receive end caused by
multipath propagation.
The output of the modulator is 70 MHz IF for connection to a suitable radio
transmitter.

Motion Estimation
Fully Exhaustive motion estimation is used. It takes a macro block of
16 pixels x 16 pixels and then performs an exhaustive search without
subsampling.
Variable Video Bit-rate
The MPEG-2 compression algorithm uses adaptive field/frame coding,
forward and backward predictive processing with motion estimation and
compensation to reduce the bit-rate to the range shown in Table 1.3.

NOTE…
Minimum bit-rate is 0.25 Mbit/s when software option M2/ESO2/PU is purchased.
12
Coding Resolutions
To provide optimum picture quality over the full range of supported
bit-rates, the encoded picture resolution is controlled automatically
according to the video bit-rate. Alternatively, the user can override this
and select manual control, if desired. Coding resolutions are shown in
Annex B, Technical Specification.
Internal Frame Synchroniser
An internal frame synchroniser is provided to accommodate slight
differences between the incoming frame rate and that generated by the
stable reference
14
used by the Encoder.
11
Noise reduction is only available when software option M2/ESO2/NR is purchased.
12
The video bit-rate depends on the Multiplexer bit-rate which is set.

.
Audio Inputs
The standard audio input is:
• AUDIO IN – 15-way male D-type - software selectable balanced
analogue or digital AES/EBU, with AES/EBU on left only. A break-out
cable is supplied which plugs into this connector and provides a more
convenient means of connecting the audio inputs via five connectors.
There are four XLR female connectors, with the fifth cable being a BNC
which provides an AES/EBU 75 Ω digital reference output.
• Alternatively, audio can be input embedded as AES/EBU on the serial
digital interface (SDI). In this mode a maximum of four stereo pairs
can be extracted from any two Data Identifiers (DIDs). Audio may be
converted to either of the standard output sampling frequencies,
32 kHz or 48 kHz, by use of the built-in asynchronous sample rate
converters. This applies only to audio which is not pre-encoded.
15
Dolby Digital (AC-3) is only available when software option M2/ESO2/AC3 is purchased.
16
To achieve lip sync in all modes the audio option M2/EOM2/AUDLIN2 must be used.
Reference Guide: E57xx DSNG and DENG Voyager Encoder Page 1-9
ST.RE.E10076.3
Introduction to the Basic Encoder
Audio Channels
The Encoder Base Board is capable of processing two stereo pairs, from
any of the following
17
:
• SDI Embedded source
• Digital source AES/EBU
• Analogue source, termination impedance 600 Ω or 20 kΩ
These signals may be processed using the encoding modes in the following
section.
Output on Digital Audio Loss
The Encoder can be software-configured, in the event of loss of digital
audio input lock loss, to either:
• Code an audio stream of silence
• Drop the audio PID
• Turn off the ASI output of the Encoder
MPEG Encoding Modes
The two stereo pairs may be configured in various encoding modes:
• Single mono: either the left or the right channel is encoded - the
signal is output to both XLR connectors at the receiving end. Not
available in Linear PCM.
• Dual mono: the left and right signals are encoded and carried in the
transport stream as a single Packetised Elementary Stream (PES) data
stream. The way that the left and right signals are output from the
Receiver is dependent on how the routing is set up on the Receiver.
Both the left and the right may be output, or the left only, or the right
only. This is typically used for multilingual services. Available in
MPEG-1 (layer 2) and Linear PCM.
• Stereo: A stereo pair is coded as two mono signals - the two signals
are output as stereo at the receiving end.
• Joint stereo: A stereo pair is coded taking advantage of the stereo
nature of the channels - the two signals are output as stereo at the
receiving end. Available in MPEG-1 (layer 2) only.
• Audio Description Service
Dolby Digital (AC-3) Encoding Modes
• 1/0: centre
• 2/0: left and right
Test Tones
The equipment can be configured to generate a test tone for alignment
purposes. Refer to Annex B, Technical Specification for level and
frequency.
Audio Variable Bit-rate
MPEG-1 audio output bit-rate (see Annex B, Technical Specification) is
selectable in the range 32 kbit/s -384 kbit/s (dependent on configuration).
17
See Annex F, Audio Modes for details of setting up the audio.
Page 1-10 Reference Guide: E57xx DSNG and DENG Voyager Encoder
ST.RE.E10076.3
Introduction to the Basic Encoder
Dolby Digital (AC-3)
Dolby Digital (AC-3) audio encoding incorporates digital normalisation,
preprocessing (filtering), dynamic range compression and the addition of
bit-stream information.
Dolby Pro Logic audio can be carried as stereo audio through the Encoder
as long as a suitably high bit-rate is selected (see Annex B, Technical
Specification).
1.3.3 Vertical Blanking Interval (VBI) Line Processing Modes
Introduction
The Encoder has three modes for processing VBI lines.
NOTE…
A maximum of eight VBI lines per field may be extracted. This limit does not apply to Teletext.
VBI in Picture
By selecting the VBI in Picture extended active picture format available in
the MPEG 4:2:2 specification the Encoder compresses and transmits the
VBI data as part of the active picture. This mode requires up to 3 Mbit/s of
extra bit-rate, depending on the amount and complexity of the VBI
present.
NOTES…
1. VBI in Picture transmits the VBI waveform as part of the picture and as such will be subject to
some distortion. Most analogue VBI types are robust against this type of distortion but others,
e.g. video index, are intended for SDI transmission and will not survive MPEG coding/decoding
in VBI in Picture mode. VITS test signal and ghost cancellation signal will become corrupted.
2. VBI in Picture is not supported when 3:2 Pulldown is active.
VBI User Data
Closed Caption data, together with other formats such as VITC and AFD,
can be transmitted in the user data field of the video or relevant part of
the video stream.
VBI in PID
The Encoder has the ability to extract and transmit a wide variety of VBI
line formats. Circuitry on the front end of the equipment incorporates a
number of general purpose line grabbers so that known formats of VBI
data can be extracted.
The following VBI data formats are supported:
• Line 21 (field 1 and field 2) data Services EIA-608 (Closed Caption and
V-chip)
• Neilson AMOL 1, Neilson AMOL 11
Reference Guide: E57xx DSNG and DENG Voyager Encoder Page 1-11
ST.RE.E10076.3
Introduction to the Basic Encoder
• VITC
18
(EBU and SMPTE)
VITC extraction from line 16 or 22 for 625-line systems (EBU
definitions), or line 14 for 525-line systems is supported.
• Programme Delivery Control (PDC), via ITU-R System B Teletext
extension data packets of type 8/30, format 2 and Line 16 Video
Programme System (VPS). Video Programming Teletext (VPT) and VPS
are trade names
• Wide Screen Signalling (WSS) (line 23) ETS 300 294
• Gemstar2x
• EIA516 (NABTS)
• Video Index (for Pan Scan, Aspect Ratio and Active Format Descriptor)
• The supported VBI line number range is 10-22 and 272-285 for 525
lines and 6-22 and 318-334 for 625 lines
Teletext Extraction
The Encoder supports internal Teletext data extraction (Teletext drop)
from the VBI of a video input and formats this data into a transport packet,
as specified in the DVB specification EN300-472. The Encoder can extract
up to 18 lines of Teletext from each field of the video frame.
Line filters can be invoked to selectively disable any individual lines in this
range. The filters are provided to allow the user to ensure that
non-Teletext lines (e.g. ITS lines) are not erroneously extracted. The
extracted Teletext lines are formatted into PES packets according to the
DVB specification. The Teletext PES packets are time-stamped to allow
correct alignment of subtitling captions with decoded video.
The following Teletext services are extractable:
• Sytem B (WST) Teletext
• Video Programming Teletext (VPT), PDC (Packet 8/30 format 2)
• Inverted Teletext
• EIA516 (NABTS)
1.3.4 Data Channels
The basic Encoder supports two data channels, an asynchronous RS-232
and a synchronous RS-442. These are provided as data pipes only, they
are not time-stamped.
1.3.5 Outputs
Three ASI-C (copper) outputs supplying a DVB and ATSC19 MPEG-2
transport stream are supplied as standard.
18
VITC: Only timecode is extracted.
19
ATSC internal PSIP generation is not supported in Build versions 2.1.0 and 2.2.0.

2.3.2 Cable Routing
Power supply cables should be routed so that they are not likely to be
walked on or pinched by items placed upon or against them. Pay particular
attention to cables at plugs, convenience receptacles, and the point where
they exit from the appliance.
Installing the Equipment
Do not run ac power cables in the same duct as signal leads.
2.3.3 Equipment Access
BERYLLIUM COPPER FINGER STRIPS ARE USED IN THIS EQUIPMENT TO SEAL THE
ENCLOSURE FOR EMI PROTECTION. THIS ARRANGEMENT IS PERFECTLY SAFE DURING
NORMAL OPERATION. DO NOT FILE THE STRIPS OR OTHERWISE CAUSE THEM TO PRODUCE
DUST OR PARTICLES. ANY CUTS CAUSED BY THE STRIP SHOULD BE TREATED
Ensure that the Encoder is installed in such a way as to allow access to the
rear of the unit and the connectors.
2.3.4 Ventilation
NEVER PUSH OBJECTS OF ANY KIND INTO THIS EQUIPMENT THROUGH OPENINGS AS THEY
MAY TOUCH DANGEROUS VOLTAGE POINTS OR SHORT-OUT PARTS THAT COULD RESULT IN
A FIRE OR ELECTRIC SHOCK. NEVER SPILL LIQUID OF ANY KIND ON THE PRODUCT.
1. Openings in the cabinet are provided for ventilation and to ensure reliable operation of the product
and to protect it from overheating, and these openings must not be blocked or covered. This product
should never be placed near or over a radiator or heat register. This product should not be placed in
a built-in installation such as a rack unless proper ventilation is provided or the instructions have
been adhered to.
2. Do not install equipment so that the air intake of one aligns with the outlet on another. Provide
baffles and adequate spacing.
3. The fans contained within this unit are not fitted with a dust/insect filter. Pay particular attention to the
environment in which it is to be used.

Installing the Equipment
The unit is designed for stationary or fixed use only. Ensure it is firmly and
safely located and has an adequate through-flow of air. Allow at least
50 mm free air-space at each side of the equipment. Units in racks can be
stacked without ventilation panels between. Racks containing stacked
equipment may need to be forced-air cooled to reduce the operating
ambient temperature. For stacking constraints contact Customer Services.
The 1U Encoder uses a similar air-flow path, with three fans on each side
of the unit. With both 1U and 2U units it is important not to block the front
air intake on the bottom-left corner of the front panel (see Figure 2.2).
