Important Notes
The HDT-70_H.264 High Definition transmitter is completely
compatible with the DVB-T/T2/S2/S Standards, included in the
European Standard ETSI EN300744 (DVB-T), ETSI EN300755 (DVBT2), ETSI EN302307 (DVB-S2) and ETSI EN300421 (DVB-S). It also
complies with the ISDB-T International technical standard (optional).
1. The control unit has available a 70 MHz output connection through which
it is possible to transmit the signal to the RF head via a triax cable in
DVB-T2, DVB-T, ISDB-T, DVB-S2 or DVB-S mode. Besides, this control
unit has another optional output connector in which the signal is
generated in the L band for DVB-S and DVB-S2.
2. This device has the ASI and IP (optional) output available when the input
is ASI. Besides, it has also the ASI output available when the input is IP
(optional).
3. It is important that when the transmitter is switched on, the selected RF
output connection must have the suitable antenna or must be loaded.
4. The HDT-70 transmitter applies an 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.
5. In 1080p Video Format, it can only be performed the Standard Delay,
not the Low Delay, Super Low Delay or Ultra Low Delay.
6. 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.
7. In case it is selected SDI input with 1080p format, the delay will be
automatically Standard.
8. Equipment’s maximum output power for the DVB-T2/T is 3 W (selectable
from 0.3 to 3 W) and for the DVB-S2/S is from -20 to + 5 dBm.
9. 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.

10.If any audio or data channel are not to be 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.
11. 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)
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.
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)
3. One of the following may happen:
a) Breathing may begin and consciousness
returns.
b) Breathing may begin but consciousness NOT
return. 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.
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).
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.
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.
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-70_H.264 High Definition Camera Transmitter
MANUAL V9.0
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.
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-70_H.264 High Definition Camera Transmitter
MANUAL V9.0
Chapter 1: Introduction
The new HDT-70 is a split box portable microwave transmitter, which
consists of a control unit and a RF head connected by triax cable. The
control unit has a 70 MHz output connection available through which it is
possible to transmit the signal to the RF head via a triax cable in DVB-T2,
DVB-T and optionally in ISDB-T, DVB-S2 or DVB-S mode. Besides, this
control unit has other optional output connectors, in one of them the signal
is generated in the L band for DVB-S and DVB-S2 and in the other you have
a multiband RF output.
Its feature H.264 encodes for 3G, high definition (HD) and standard
definition (SD) signals. Based on NEL encoding technology, the new HDT-70
offers the highest video quality with minimum latency, 33 ms. H.264
transmission is possible using 40% lower bitrate than conventional MPEG-2
systems. For added security, transmitted signal can be encrypted using
BISS encryption.
This new generation transmitter accepts 3G/HD/SD-SDI, HDMI and
analogue video input signals. SDI embedded, HDMI embedded, AES audio
and analogue inputs are available as standard. User or GPS data can be
transmitted over the data channel.
ASI input and Transport Stream over IP input make possible to use this
transmitter as a modulator. Besides, the ASI output and the Transport
Stream over IP output (optional) enables the user to use the transmitter as
a standalone encoder.
The HDT-70 transmitter performs DVB-T2, DVB-T and optionally ISDB-T,
DVB-S and DVB-S2 modulations. DVB-T enables compatibility with neatly all
types of COFDM receivers. DVB-T2 modulation outperforms DVB-T
modulation, and offers much higher data rate, which renders in a higher
signal quality or much more robust signal than DVB-T, making possible
longer and more difficult links. This transmitter also can perform DVB-S2
and DVB-S modulations. An L band optional output is available which
enables the user to handle the transmitter control unit as satellite encoder &
modulator unit.

HDT-70_H.264 High Definition Camera Transmitter
MANUAL V9.0
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 or 4 digital audios embedded on the SDI signal. The video
formats can be 1080p (only in Standard Delay mode), 1080i, 720p, 576i or
480i. This transmitter also has a test pattern and 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 216 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 or BISS-E scrambling
system. Encrypted signal will only be received by the receivers that have a
valid descrambling key.
Transmitter system operation is very easy. It has a display and a keyboard
which make possible the configuration and monitorization of every
parameter of the equipment.
The equipment is fed with AC power supply from 90 to 240 V.
Its excellent design, mechanical and electronic assembly make the HDT-70
a robust and reliable solution.
DVB-T2 features
Its maximum output power is 3 Watt. High quality components have been
used to achieve the best output signal quality.
The HDT-70 digital camera transmitter uses COFDM (Coded Orthogonal
Frequency Division Multiplexing) modulation system (1K, 2K, 4K, 8K and
8K.ext) which provides superior signal robustness and a higher link
performance. This technology provides operators with efficient means to
overcome the challenges of NLOS propagation and mobile channels
propagation.
OFDM spread spectrum modulation system distributes the data over a large
number of closely-spaced carriers, for example, 1.705 carriers in 2K mode.
The data are divided into several parallel data streams, one for each carrier,
so, 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.
16
HDT-70_H.264 High Definition Camera Transmitter
MANUAL V9.0
An OFDM modulated signal, since uses a low symbol rate modulation
scheme (i.e. where the symbols are relatively long compared to the channel
time characteristics) suffer less from intersymbol interference caused by
multipath propagation. As the duration of each symbol is long, it is feasible
to insert a guard interval between the OFDM symbols, thus eliminating the
intersymbol and co-channel interference. So, if one carrier’s information is
lost, it would only be lost a small part of the whole information.
Besides, in OFDM, the sub-carrier frequencies are chosen so that the subcarriers are orthogonal to each other, meaning that cross-talk, interference,
between the sub-channels is eliminated. The orthogonality allows high
spectral efficiency.
On the other hand, OFDM 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
in 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 capable to transmit is lower.
Used modulation scheme of each OFDM sub-carrier, QPSK, 16QAM, 64QAM
and 256 QAM is also connected with signal robustness and transmitted bit
rate. QPSK is the most robust and 256QAM is able to transport a higher bit
rate.
Besides, the system can define 7 guard intervals: 1/4, 19/128, 1/8, 19/256,
1/16, 1/32 and 1/128. The guard interval is used to reduce intersymbol
interferences due to the multipath propagation.
In addition, it also provides several bandwidths: 1.7, 5, 6, 7 and 8 MHz in
case there are needed for different applications.
To summarize, with all of these characteristics, the maximum bit rate
achieved is 44.6 Mbps.

DVB-T features
The RF stage of the HDT-70 transmitter is the same as the DVB-T2 one. The
difference is found in the modulation part as it is commented bellow.
The HDT-70 digital camera transmitter uses COFDM (Coded Orthogonal
Frequency Division Multiplexing) modulation system (2K mode).
The available modulations are QPSK, 16QAM or 64QAM where the most
robust is the QPSK one and the one with the bigger bit rate is the 64QAM.
The European ETSI EN 300744 standard defines the following convolutional
coding rates: 1/2, 2/3, 3/4, 5/6, 7/8.
Used modulation scheme of each OFDM sub-carrier, QPSK, 16QAM and
64QAM, is also connected with signal robustness and transmitted bit rate.
QPSK is the most robust and 64QAM is able to transport a higher bit rate.
Besides, the system can define 4 guard intervals: 1/4, 1/8, 1/16 and 1/32.
In conclusion, with all of these characteristics, the maximum bit rate
achieved is 31.67 Mbps.
DVB-S2 features (optional)
In case the HDT-70 transmitter is needed to be used as a satellite
transmitter, it features an optional IF stage in the L band , that L band
output that provides a 10 MHz reference oscillator.
The HDT-70 digital camera transmitter uses single carrier or one modulation
from the next available: QPSK, 8PSK, 16APSK or 32APSK where the most
robust is the QPSK one and the one with the bigger bit rate is the 32APSK.
In addition, the European ETSI EN 302307 standard defines the following
LDPC coding rates: 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10.
In the modulation step it is also included a roll off factor (0.20, 0.25, 0.35)
which is used to reduce intersymbol interference where the value that most
reduces interference but with less bandwidth is 0.20.
To sum up, with all of these characteristics, the maximum bit rate achieved
is 31 Msym/s.

static then it means presence of that signal. If the character is
blinking then it means absence of that signal.
Audios status indication: If audio 1 or 2 is not darkened then it is
enabled. On the other hand, if audio 1 or 2 is darkened then it is
disabled.
Data status indication: If this field is not darkened then it means that
data is enabled. On the other hand, if this value is darkened it means
that data is disabled. Moreover, in case this field is static, its meaning is
presence of the data whereas if this field is blinking, it means absence of
the data.
