Important Notes
1. The HDT-04 transmitter is completely compatible with the DVB-T/T2
Standards, included in the European Standard ETSI EN300744 (DVB-T),
ETSI EN300755 (DVB-T2). It also complies with the ISDB-T International
technical standard (optional).
2. It is important that when the transmitter is switched on, the selected RF
output connection must have the suitable antenna or must be loaded.
3. The HDT-04 transmitter applies a MPEG-4 compression to either HDMI,
composite video or SDI input signals. An MPEG-1 layer 2 compression is
applied to the corresponding 4 analogue audio channels, the 2 stereo SDI
embedded, the HDMI embedded and the AES digital audio signals. The
resulting multiplexed signal is transmitted using COFDM modulation
system.
4. The HDT-04 transmitter is available in different frequency bands from 2
to 5 GHz, for the DVB-T2 and DVB-T RF stage. It can also perform ISDBT with interlaced (optional). The frequency band is defined on the product
P/N.
5. If the RF output is set to DVB-T2 and the bandwidth selected is 1.7 MHz,
then, the device automatically disables the Audio2 and it sets the bitrate
of the Audio1 to 128 kbps.
6. Special care should be taken with SDI cables, quality and length, these
are very important, especially when HD-SDI or 3G SDI signals are
transmitted.
7. If any audio or data channel are not used in a transmission, they should
be disabled, in order to assign that bitrate to the video and achieve a
higher quality transmitted video signal.
8. Only authorized personnel should open the product and any repair or
warranty will be invalidated if the seals are broken.

First Aid in Case of Electric Shock
DO NOT TOUCH THE VICTIM WITH YOUR BARE HANDS until the circuit is
broken. SWITCH OFF. If this is not possible, PROTECT YOURSELF with DRY
insulating material and pull the victim clear of the conductor.
If breathing has stopped, indicated by unconsciousness, lack of respiratory
movements and a ‘blue’ look to cheeks, lips, ears and nails, START
RESUSCITATION AT ONCE.
EMERGENCY RESUSCITATION – THE EXPIRED AIR METHOD
(Approved by the Royal Life Saving Society)
Chapter 1: If possible, lie the victim on his back with his head slightly higher
than his feet. Clear the mouth and throat of any obvious obstruction.
Chapter 2: Kneel on one side of the victim, level with his head. LIFT THE JAW
AND TILT THE HEAD BACK AS FAR AS POSSIBLE (Figs. 1a and 1b)
Chapter 3: One of the following may happen:
a) Breathing may begin and consciousness returns.
b) Breathing may begin but consciousness NOT
returns. Turn the victim on his side and ensure
that the airway is kept clear.
c) Breathing may return but be NOISY which
means that the airway is not fully clear. Try to
clear the airway.
Chapter 4: IF THERE NO SIGN OF BREATHING:
a) Check that the head is still tilted back.
b) Take a deep breath.
c) Pinch the victim’s nose and blow firmly into his
mouth (Fig. 2). As you do, the chest will RISE.
d) Turn your head away and take another breath,
watching for the chest to FALL (Fig. 3).
Chapter 5: Start with four quick breaths and then continue
with one breath every five seconds (i.e. 12 times a minute).
This should be continued until the victim revives or a doctor
certifies death.
Chapter 6: As consciousness returns the victim will start to
breathe on his own, and a ‘pink’ color replaces the ‘blue’ look:
this is the time to stop resuscitation. Continue to hold his chin
up and so keep the airway clear.
Chapter 7: In the case of injuries to the mouth, it may be necessary to use
mouth-to-nose resuscitation. Seal the victim’s mouth with your cheek and
blow firmly into his nose, proceeding as above.
9
HDT-04 High Power Transmitter
USER’S MANUAL V9.9
Chapter 8: In the case of severe facial injuries, it may be necessary to do a
manual method of artificial respiration (Silvester-Brosch or Holger Nielsen).
Briefly, these methods apply compression to ribcage with the victim lying on
his back (S-B) or face down (H.N.) with associated movement of his arms up
and out. The cycle of movement should take about five seconds, i.e. the
normal breathing phase.
Chapter 9: Whatever the method, it is ESSENTIAL to commence resuscitation
WITHOUT DELAY and to send for medical assistance immediately.
TREATMENT FOR BURNS
If the victim is also suffering from burns, then, without hindrance to
resuscitation, observe the following:
a) DO NOT ATTEMP TO REMOVE CLOTHING ADHERING TO THE BURN.
b) If possible, alleviate the pain from the burnt part by immersing in
cold water.
c) If help as available or as soon as resuscitation is no longer required,
the wound should be covered with a DRY clean dressing.
d) Oil or grease in any form should not be applied.
e) If severely burnt, get the victim to hospital immediately.

HDT-04 High Power Transmitter
USER’S MANUAL V9.9
Chapter 1: Introduction
The HDT-04 is the new high power transmitter developed by SVP Broadcast
Microwave which provides an output power of 10 W in the frequency ranges
of 2,010 to 2,390 MHz, 2,300 to 2,700 MHz, 4,400 to 5,000 MHz or 5,000 to
5,300 MHz and an output power of 5 W in the frequency range of 3,300 to
3,600 MHz.
Its feature H.264 encodes for 3G, high definition (HD) and standard definition
(SD) signals with ultra-low latency. H.264 transmission is possible using 40%
lower bitrate than conventional MPEG-2 systems.
This new generation transmitter accepts analogue video, 3G/HD/SD-SDI and
HDMI video input signals. Analogue, SDI embedded, HDMI embedded and
AES/EBU audio inputs are available as standard. User data or GPS data can
be transmitted over the data channel.
The ASI output enables the user to use the transmitter as a standalone
encoder.
The HDT-04 transmitter performs DVB-T2, DVB-T and ISDB-T (optional),
modulations.
Moreover, it expands the possibilities of COFDM digital links on the market
using linearization technology to minimize distortion and to provide superior
signal quality for complex multicarrier modulations.
Control, operation and monitoring of the HDT-04 transmitter are very
friendly. All the parameters can be configured in field. A wide range of
accessories allow using this equipment in many different applications.
An excellent design, mechanical and electronic assembly make the HDT-04 a
robust and reliable solution.
For applications of high security, the HDT-04 transmitter has the option of
AES-128 and AES-256 encryption.
13
HDT-04 High Power Transmitter
USER’S MANUAL V9.9
Features
Input video signals, composite video, 3G–SDI, HD-SDI, SD-SDI or HDMI are
MPEG-4 encoded, together with 4 analogue audios, 2 stereo AES/EBU
channels, HDMI embedded or 4 digital audios embedded on the SDI signal.
The video formats can be 1080p, 1080i, 720p, 576i or 480i. This transmitter
also has a test pattern and a test tone generator available.
This device has a data channel available that allows transmitting user data or
GPS data as well as a Transport Stream ASI input so it can be used as a
repeater.
The encoder uses a H.264/MPEG-4 Part 10 video compression that provides
output bitrates from 1 Mbps to 100 Mbps and a MPEG-1 Layer II audio
compression which supplies different audio bit rates (128, 192, 256 or 384
Kbps).
Encoded signals can be encrypted using BISS-1, BISS-E, AES-128 and AES256 (optionally) scrambling system. The encrypted signal will only be
received by the receivers that have a valid descrambling key.
The transmitter system operation is very easy. It has a display and a
keyboard which make possible the configuration and monitoring of every
parameter of the equipment.
The equipment is fed with DC power supply from 12 to 36V. It has good
harmonic rejection and isolator for protection against high VSWR.
It also has a waterproof radiator that dissipates heat through a fan. The fan
is activated when the temperature exceeds 40ºC.
DVB-T2 features
This transmitter uses COFDM (Coded Orthogonal Frequency Division
Multiplexing) modulation system (1K, 2K) which provides superior signal
robustness and a higher link performance. This technology provides the
operators efficient means to overcome the challenges of NLOS propagation
and mobile channel propagation.
COFDM spread spectrum modulation system distributes the data over a large
number of closely-spaced carriers, for example, 1705 carriers in 2K mode.
The data is divided into several parallel data streams, one for each carrier, so
that each carrier transports a lower data rate and the symbol duration is
longer. Each carrier is then modulated with a QPSK, 16QAM, 64QAM or
256QAM scheme with a constellation rotation.
14
HDT-04 High Power Transmitter
USER’S MANUAL V9.9
COFDM modulated signal, since it uses a low symbol rate modulation scheme
(i.e. the symbols are relatively long compared to the channel time
characteristics), suffers less from inter symbol interference caused by
multipath propagation. As the duration of each symbol is long, it is feasible
to insert a guard interval between the COFDM symbols, thus eliminating the
inter symbol and co-channel interference. So, if one carrier’s information is
lost, only a small part of the whole information will be lost.
Besides, in COFDM the sub-carrier frequencies are chosen so that the subcarriers are orthogonal to each other, thus cross-talk, the interference
between the sub-channels, is eliminated. Furthermore, the orthogonality
allows high spectral efficiency.
On the other hand, COFDM system is invariably used in conjunction with
channel coding (forward error correction). The error correction code used in
this equipment is Reed-Solomon coding, which is concatenated with LDPC,
and there is an additional interleaving between the two layers of coding. Error
correcting codes build redundancy into the transmitted data stream. This
redundancy allows bits that are in error or even missing to be corrected at
the receiver.
The European ETSI EN 300755 standard defines the following LDPC coding
rates: 1/2, 3/5, 2/3, 3/4, 4/5, 5/6. There is a compromise between the coding
rate (signal robustness) and the transmitted bit rate. If the coding rate is
higher the signal transmission is more robust (1/2 is the most robust) but the
bit rate that the system is able to transmit is lower.
The modulation scheme used on each COFDM sub-carrier (QPSK, 16QAM,
64QAM and 256 QAM) is also thus related to the signal robustness and the
transmitted bit rate. QPSK is the most robust and 256QAM is able to transport
the highest bit rate.
Besides, the system can define 3 guard intervals: 1/8, 1/16 and 1/32. The
guard interval is used to reduce inter symbol interferences due to the
multipath propagation.
In addition, it also provides several bandwidths: 1.7, 6, 7 and 8 MHz, for
different applications.
The maximum bit rate achieved is 46 Mbps.
15
HDT-04 High Power Transmitter
USER’S MANUAL V9.9
DVB-T features
The RF stage of the HDT-04 transmitter for DVB-T is the same as the one
described for DVB-T2. The only differences are found in the modulation part,
as it is commented below.
The HDT-04 transmitter uses COFDM (Coded Orthogonal Frequency Division
Multiplexing) modulation system (2K mode).
The available modulations are: QPSK, 16QAM or 64QAM. Of them, the most
robust one is QPSK and the one with the maximum bit rate is 64 QAM.
The European ETSI EN 300744 standard defines the following convolutional
coding rates: 1/2, 2/3, 3/4, 5/6, 7/8.
The modulation scheme used on each OFDM sub-carrier (QPSK, 16QAM and
64QAM) is also thus related to the signal robustness and the transmitted bit
rate. QPSK is the most robust and 64QAM is able to transport the highest bit
rate.
Besides, the system can define 3 guard intervals: 1/8, 1/16 and 1/32.
Finally, the maximum bit rate achieved is 31.67 Mbps.
