Recommendation ITU-R SM.575-3 – “Protection of fixed monitoring stations against
interference from nearby or strong transmitters”
Source: Brief description:
WP 1C
Strong RF signals may reduce the ability of a monitoring station to receive weak signals and
measure them correctly. The protection of radio monitoring stations against strong RF
signals is of particular importance in view of the increasing number of antenna sites for
mobile and other radio services. Since monitoring stations are often located in urban areas
and exposed spots, it becomes more and more difficult to identify suitable new sites and to
protect the existing ones.
This Recommendation specifies maximum field-strength levels at monitoring stations to
ensure their interference-free operation. Its annex describes procedures and calculations
for the establishment of protection zones around radio monitoring stations

why there has been inconsistent interest among administrations or demand from listeners to make a complete
WP 6A transition to digital sound broadcasting. Some administrations have strongly supported a transition, others
have taken a cautious approach and some have expressed little interest.
This Report seeks to highlight the benefits of digital sound broadcasting and reports on some successful
implementations This Report also seeks to address some of the negative comments made during public
consultations, particular by consumer groups, expressed on ceasing analogue sound broadcasting and goes on
to address the technical and economic factors involved in bringing the advantages of digital sound broadcasting
to all listeners around the world.
The traditional model of sound broadcasting faces challenges that make it essential to pursue the goal of
moving to digital modulation techniques. For administrations and broadcasters, the analogue modulation
techniques of amplitude modulation (AM) and frequency modulation (FM) used around the world for sound
broadcasting do not provide the optimum use of spectrum. For listeners, audio quality is often compromised
by adverse propagation conditions or interference, from a combination of man-made noise sources and over-
use of the available frequency bands. However, in order to command the interest and support of listeners in

Quotes from existing text in ITU-R are highlighted through the use of Italics.
It should be noted that for Band I, II, III, IV and V systems broadcasters quote antenna gains and
effective radiated power (ERP) relative to a dipole. So, for example, a DTT receiving antenna
with a quoted gain of 7 dB has a gain of 9.15 dBi when referenced to an isotropic source. Also, a
broadcast station with a quoted ERP of 20 kW (43 dBW) has an e.i.r.p. of 75.15 dBm.

The objective of this Report is to introduce methods that have been used for evaluating the quality of

Recommendation ITU-R BT.1735 provides two methods for digital objective reception quality
assessment for DVB-T, one for multi-frequency networks (MFN) and one for single frequency
networks (SFN).
This Report gives some details about the relevant parameters for DVB-T2 and the results of some
measurements, in order to identify a possible method for objective reception quality assessment for
this DTTB system.
The final goal would be to obtain criteria that, even without knowing exactly all the useful signals and
the interferences but looking only at a limited number of parameters, could indicate if a requested
level of C/I is satisfied and quantify the available “margin” with respect to the QEF threshold.
Measurements in the field should be performed in a known controlled order to validate the proposed

Report ITU-R BT.2446-1 – “Methods for conversion of high dynamic range content to standard
dynamic range content and vice-versa”
Source:
Brief description:
WP 6C
High dynamic range (HDR) content may be converted to a significantly lower dynamic range so
that it may be displayed on a standard dynamic range (SDR) display device. As the dynamic
range mismatch between content and display capabilities can be significant, the manner in
which the dynamic range is reduced impacts the visual quality that can be achieved. Likewise,
SDR content, such as for instance legacy content, may be converted to HDR content to enable
display on a HDR display device, or to bring such content into a HDR video workflow. This
Report provides guidance toward the design of methods that achieve such conversions, which
are referred to as tone mapping and inverse tone mapping, and it presents example methods
along with their evaluation.

This Report contains a summary of the frequency sharing characteristics of digital terrestrial
television broadcasting (DTTB) broadcast systems, operating in the frequency range 470-862
MHz, required for relevant compatibility studies.
It should be noted that for Band I, II, III, IV and V systems broadcasters quote antenna gains
and effective radiated power (ERP) relative to a dipole. So, for example, a DTT receiving
antenna with a quoted gain of 7 dB has a gain of 9.15 dBi when referenced to an isotropic
source. Also, a broadcast station with a quoted ERP of 200 kW (53 dBW) has an e.i.r.p. of
85.15 dBm.

Report ITU-R BT.2470-1 – “Use of Monte Carlo simulation to model interference into DTTB”
Brief description:
SG 6
Monte Carlo simulation is a statistical method widely used to solve complex mathematical problems, to model physical
phenomena or to understand complex real-life problems that cannot be easily modelled by analytical methods. For
example, Monte Carlo simulation is used to study collision of atoms, polymer dynamics as well as financial risks.
Source: Monte Carlo simulation is based on random sampling to generate a large number of events (experiments), according to the
WP 6A model implemented to describe a physical phenomenon. Each generated event, output of the simulation, can be
considered as a snapshot in time.
Monte Carlo simulation is increasingly being used to assess the compatibility between radio systems. The simulation
typically considers randomly distributed sources of interference and randomly distributed or fixed victim receivers.
Different system parameters can also be modelled as random variables defined by given probability distributions. Most
often, the output of the simulation is processed to calculate the probability of interference to the victim receiver or the loss
of data throughput in a network.
A deterministic method is used to assess the compatibility between radio systems with a fixed interference configuration.
However, it is unable to predict the probability of interference if the interference configuration is not fixed and
consequently the risk of interference to the victim system. The merit of Monte Carlo simulation is its ability to create a very
high number of possible interference configurations, covering the variability in a system, when assessing the compatibility
between radio systems and by doing so assess the risk of interference in a more realistic way compared to a deterministic
assessment.
This Report expands on Report ITU-R SM.2028 providing further information on how to model interference into DTTB
Approval date: services using Monte Carlo simulation. The description and examples presented in this report are based on SEAMCAT, but
