10 TVBEurope News Digital switch for Turkey
IN 2011 the Turkish government launched a new TV and radio law from RTUK (Radio and Television Supreme Council), the regulatory authority. The law fixed as follows: that within one year, the digital terrestrial television frequency planning would be done by RTUK; within one year after the first year (when the frequency planning should be in hand) the tender of the digital terrestrial television licenses would be done; and that within two years after the tender and the authorisation of the terrestrial broadcasters, the installations and line up of the digital terrestrial system would be done. There was a special article in
the law saying that after the authorisation of the digital terrestrial licenses, the national terrestrial license holders should establish a single company to install and manage the new digital terrestrial systems and transmitting stations. In order to be ready for operation at sites, the present national broadcasters and the public broadcaster (TRT) established a new joint venture company called Anten AS in May 2012.
Having been accepted as a deadline to switch off terrestrial television broadcasting in analogue and line up digital terrestrial no later than 2015, Turkey is running the transition period from analogue to digital. Guest Opinion on the transition by Ibrahim Cucioglu, deputy general manager (Technical), Anten TRT was allocated one special
multiplex and five multiplexes were tendered out in April 2013 by RTUK, the regulatory authority for the national broadcasters with 11 HD channels (consisting of eight entertainment and three thematic plus 22 SD channels consisting of 11 entertainment and 11 thematic). Following the launch of the

installed and some changes were made in the present stations. The trial was lined up at the beginning of March 2013 on a 27Mbps multiplex with two HD and five SD channels. The SFN network of the trial includes three main transmitting sites. Two of the present antenna systems were used and one antenna system was newly installed — but all of the transmitting stations are the existing ones.
A total of seven multiplexes are planned nationwide: one mux for the public broadcaster, five for the national broadcasters and one for the regional and locals

RTUK launched the frequency planning parameters in December 2012 with the following considerations: system is DVB- T2; modulation is 64 QAM; FEC
2/3; guard interval of 19/256 (266 uS); FFT size 32K; pilot pattern PP4; and capacity of 27Mbps. It targeted indoor reception in the 16 biggest cities as well as portable outdoor reception for the rest. A total of seven multiplexes are planned nationwide: one mux for the public broadcaster, five for the national broadcasters and one for the regional and locals.
TriCaster sails ahead
Melanie Dayasena-Lowe visited NewTek at its EMEA HQ last month to hear about new product news, watch technology demonstrations and learn more from one of its customers
NEWTEK HOSTED an event last month at its EMEA headquarters in Windsor where the company unveiled exclusive product news. The next generation of its entry-level TriCaster 40 is an HD multi-camera video production studio that enables users to create professional streaming TV on a small budget. Carter Holland, chief marketing
officer, explained the factors behind its release: “We designed the TriCaster 40 as a low-cost, entry-level solution that would be ideal for schools, video bloggers, small businesses — even local broadcasters — who often face the challenge of figuring out how to
create video programming that looks very professional but with a very limited budget. “When talking with these customers, one of the most common requests has been more graphics and visual capabilities that enhance video footage with branded elements, making shows look and feel like something you might see on network television. We’ve responded to that request with Version 2 of TriCaster 40, incorporating a wide variety of templates to create and customise full colour graphics, animated transitions, and pristine titles — all of which are common branding attributes in a network broadcast.
“There are many other enhancements as well, but the primary focus was to empower this group of customers with more creative and visual control so they can produce content that engages their audience with the same kind of experience they get when they watch traditional TV”. At the event Sam Usher,
managing director of Red Handed TV, explained how NewTek technology has helped his business to grow. Red Handed TV’s main broadcast/digital work is in the field of sport and the company has experience in difficult terrain live and highlights packages. One of its main clients

with NewTek three years ago when the AWMRT decided it wanted live streaming and TV from every venue. “We needed to find a way to reduce weight and setup time and therefore be more cost effective. I discovered the TriCaster and decided that we would base our whole live offering around it. We have since configured a whole liverig with five cameras, talkback,
slow-motion replay, etc, cameras and cables, which weighs in at around 1,200kg,” said Usher. Up until now Usher has used a
TriCaster 850 with a 455 as a backup, but he plans to switch to the 8000. “The new 8000 will allow us to step up our production capabilities, with different output codecs, and system mirroring. We are also probably going to move to the new 3Play 4800 as well for one of our potential new clients.”

the permission of RTUK. All of the present stations were studied according to the extra capacity for the DVB-T2 broadcast in terms of energy, antenna system and also suitable antenna pattern — which has to be similar to the frequency plan parameters. As soon as the project was
formed, transmitters, new antenna systems, head-end and the other equipment were
Anten has used different brands and types of equipment in the trial. The outdoor measurements have been completed and the indoor measurements, have begun. Anten has prepared the deployment project but perhaps it will need a slight arrangement in the main project after the results of the trial, in terms of comparisons between the theoretical and the measured (practical) values.
