New CHIRplus_BC v. 5.6.0 Release includes DVB-T2 and ISDB-T Planning Functions<br />
The new CHIRplus_BC version 5.6.0<br />
for broadcast planning and coordination<br />
now covers DVB-T2 as well as<br />
ISDB-T planning functions, whereas<br />
the last major release 5.4.0 concerned<br />
multi-core calculations.<br />
The new version has already been<br />
delivered to customers under<br />
maintenance.<br />
DVB-T2, which is also subject to ITU’s<br />
Recommendation BT.1877, “Error-correction,<br />
data framing, modulation and<br />
emission methods for second generation<br />
of digital terrestrial television<br />
broadcasting systems”, offers enhanced<br />
fl exibility to broadcasters,<br />
ranging from physical layer pipes<br />
(PLPs) to MISO (Multiple-Input Single<br />
Output). The advantage of MISO is that<br />
two variants of the signal can be transmitted<br />
from different sites, offering<br />
more network gain than the SFN operation<br />
known from DVB-T.<br />
Many countries – especially developing<br />
countries – are considering adopting<br />
this second-generation system<br />
immediately after their future analogue<br />
switch-off (ASO). South Africa<br />
and Mozambique in Africa and Serbia<br />
in Europe have decided to take a short<br />
cut and change directly from analogue<br />
technology to DVB-T2.<br />
CHIRplus_BC takes into consideration<br />
the higher complexity which comes<br />
with the DVB-T2 system, with more<br />
parameters than the classical DVB-T,<br />
and offers enhanced confi guration<br />
possibilities and pre-sets for the various<br />
T2-constellations and reception<br />
modes.<br />
As not all combinations of pilot pattern,<br />
constellation and guard interval,<br />
etc, are possible<br />
according to the<br />
DVB-T2 specifi cation,<br />
the user is<br />
only able to select<br />
valid combinations<br />
in CHIRplus_BC.<br />
The “pilot pattern”<br />
selection shows<br />
only those in green<br />
that result in a valid<br />
combination.<br />

CHIRplus_BC also<br />

Nationwide Hybrid TV DVB-T2 Network Study in Asian Country<br />
A private broadcasting<br />
company in an Asian country<br />
asked <strong>LS</strong> <strong>telcom</strong> to carry<br />
out a nationwide DVB-T2<br />
study in order to offer<br />
hybrid TV to its customers.<br />
<strong>LS</strong> <strong>telcom</strong> designed several nationwide<br />
single frequency networks (SFN)<br />
based on the required data capacity<br />
and reception mode. The objective<br />
was to optimise the system in terms<br />
of the number of sites used and the<br />
targeted coverage area and population.<br />
The study included the selection<br />
of the most suitable DVB-T2 system<br />
technology.<br />
<strong>LS</strong> <strong>telcom</strong> also carried out interference<br />
analyses with respect to analogue<br />
TV in the country, analogue and<br />
digital TV on borders and with respect<br />
to non-broadcasting services.<br />
This went along with measures to<br />
reduce or avoid interference.<br />
At the end of the study <strong>LS</strong> <strong>telcom</strong> set<br />
up the Request for Information (RFI)<br />
DVB-T/T2 countrywide network design for Montenegro<br />
On behalf of the public broadcaster<br />
RDC an initial planning<br />

• technology cost<br />
• operational expenditure<br />
• or any other parameter that you<br />
would like us to check<br />
including all the engineering and system<br />
details necessary to build the<br />
system. The RFI was sent to the<br />
potential suppliers. Finally the submitted<br />
DVB-T2 proposals were analysed<br />
and evaluated based on several<br />
criteria like equipment, price quote,<br />
schedule, customer service plan and<br />
reputation. �

UHF Television Spectrum Audit - Nigeria<br />
<strong>LS</strong> of South Africa recently performed<br />
a spectrum audit of UHF television<br />
frequency usage in Nigeria.<br />
The idea behind this was to create an<br />
accurate frequency database to<br />
determine which frequencies will be<br />
avail-able for DTT implementation.<br />
The sources of information used<br />
during the investigation included the<br />
Geneva 06 analogue and digital frequency<br />
lists, the National Broadcasting<br />
Commission (NBC) list of<br />
frequency assignments and the information<br />
obtained during our national<br />
frequency meas-urements.<br />
The measurements were done using a<br />
Rohde & Schwarz EB200 receiver<br />
In parallel to recent innovations in the<br />
area of fl ight control and embedded<br />
electronics of UAV, there has been<br />
important progress in data transmission<br />
and storage of measurement<br />
devices. We have identifi ed that combining<br />
the two; there are numerous<br />
new market opportunities.<br />

During the past three years <strong>LS</strong> of<br />
South Africa has increased its staff so<br />
that four installation teams are available<br />
for installation projects at all times.<br />
The containers, which are pre-manufactured<br />
or modifi ed to house telecommunication<br />
equipment, are<br />
delivered to the new assembly facility<br />
in Johannesburg.<br />
There, the <strong>LS</strong> team fi ts out the container<br />
units with transmission equipment<br />
and all electrical wiring, RF cabling<br />
and control wiring. Once all equipment<br />
is installed and interconnected, it is<br />
exposed to a range of tests as part of<br />
A study using the broadcast planning<br />
tool CHIRplus_BC illustrates<br />
the feasibility of large scale SFNs<br />
(Single Frequency Networks). Based<br />
on the DVB-T network in Southern<br />
Germany the coverage for a fixed<br />
reception scenario and for a portable<br />
reception scenario is evaluated.<br />

High Demand for<br />
CHIRplus_BC<br />
The digitisation of broadcasting is<br />
keeping the demand for broadcast<br />
planning and coordination tools at a<br />
high level. Recent implementations at<br />
customers in Vietnam, Oman, Bahrain<br />
and Russia prove CHIRplus_BC’s<br />
leading role in its market. �<br />
Wave Propagation<br />
Model Calibration -<br />
Zambia<br />
<strong>LS</strong> of South Africa was recently<br />
requested by a client to perform wave<br />
propagation model calibration for a<br />
client in Zambia.<br />
The calibration was done for CHIRplus_BC<br />
and more specifi cally for<br />
DVB-T2 coverage predictions.<br />
A FSH6 Spectrum Analyser from<br />
Rohde & Schwarz with a GP600<br />
antenna was used together with a GPS<br />
and a laptop for the data logging. The<br />
antenna pattern and gain were analysed,<br />
cable losses were measured<br />
and the complete measuring system<br />
was calibrated. The measurements<br />
included all morpho classes over a<br />
large coverage area.<br />
The results were analysed with<br />
CHIRplus_BC v560 and all the<br />
measurements were then divided<br />
into the different morpho classes.<br />
Our wave propagation prediction<br />
model was then calibrated against<br />
the measured values. A sample of<br />
such results is included below. �<br />
