Video can be input to the unit in seri al digital component (SDI) format or
composite analogue (PAL/NTSC). There is also a logo overlay facility
allowing broadcasters to trademark material.
The audio functionality supports multiple sampling frequencies, bit-rates
and coding modes. Audio can be input in balanced analogue, digital
AES/EBU input as a discrete channel or embedded on serial digital video.
Various coding standards are supported, including Linear PCM. Additional
audio channels can be accommodated by purchasing the option module

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.
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.

Figure 1.6: Typical DENG System Configuration
The OFDM modulator fitted in the E5715 and 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 mak es the sy stem 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-Sol omon (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 b y
convolutional (Viterbi) decoding followed by RS decoding.
Five convolutional rates are available: ½,
2
/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 provid e d ifferent 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.

Introduction to the Bas ic Enc o der
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 W 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.
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 W or 20 kW
These signals may be processed using the encoding modes in the following
section.
MPEG Encoding Modes
The two stereo pairs may be configured in various encoding modes:
·Single mono: the left 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 si gnals
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.

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 Table 1.5) is selectable in the range
32 kbit/s -384 kbit/s (dependent on configuration).
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 audi o through the Encoder
as long as a suitably high bit-rate is selected.

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 transm its 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.
Instruction Manual: evolution 50 00 E57xx DSNG and DENG Voyager Encode rPage 1-13
ST.TM.E10076.3
Introduction to the Bas ic Enc o der
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. Circui try on the f ront 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
· VITC (EBU and SMPTE)
· 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
· 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 7-24 and 319-336 for 625 lines
Teletext Extraction
The Encoder supports internal Teletext data extraction (Tel etex t d rop )
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 provid ed 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
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.
