What will 5G bring to broadcasting?

To be honest, I do not know the answer of the question: What will 5G bring to broadcasting? But, with the help of some documents, I will try to comment on this. It would be great if you also can share your opinions. "Broadcast", "unicast" and "multicast" are different ways of connection. Visualization is always better way of explaining: As you can see in the figure above, Unicast is point to single   point connection; Broadcast is point to all connection; Multicast is point to many points connection.  In broadcast connections, quality does not depend on the number of receiving units. So for serving same data to crowded receipents some kind of broadcast network should be used.  Mobile networks were providing unicast connections, i.e. from the base station to the receiver. Multimedia Broadcast Multicast Service ( MBMS ) is a broadcast/multicast service in mobile networks, which is available since 2009 . But it has not been common

digital radio in Sweden: what is happening?

Time to time, it becomes extremely difficult for me to follow up the progress in technology. The main reason for this is nothing but MONEY :)  I have to finance all my trips to events, at which I have the chance to meet colleagues from industry and ask my questions. But, for some events, the cost for the event is too high, like the DVB World Congress in Venice. Although I bought the tickets for the flight & booked a hotel on my own, it seems that I will not find a way to attend the event, as it is not possible for me to pay 1000 € for a two day congress. The title of this post is again on the same issue, the unability to attend the events. As you may already know, there is a hot topic in the digital radio world: Sweden. It is a country of social democrats and a heaven for some, because of this. This Nordic country, has been trying the digital radio for many years and now decided not to proceed any more. It is quite interesting as another Nordic, Norway, is preparing

Once again digital radio, an interview with Attila Ladanyi, CTO of T & C Holding and Board Member of the RDS-Forum.

Paris / January 2014 As you may noticed, I posted two interviews on digital radio, one of which is with Mr. Patrick Hannon & the second is with Ms. Ruxandra Obreja. I am pleased to say that both interviews were very informative for me & also for the Turkish market. I was working on the digital radio transition project professionally when I posted those interviews. After a change in my position, although I am not directly involved in the project any more, I keep following the progress and still try to understand the technology. This is the third interview with the same 4 questions. Mr. Attila Ladanyi is the CTO of T & C Holding and also a Board Member of the RDS - Forum. The photo in this post is from Paris. 1. There are many examples of digital radio transitions all over the world. Some are great success whereas some are total fail.  I think there is not a one-right-path to follow. What do you recommend us, I mean in Turkey, with all those experiences? I do

DAB, DAB+, DRM30, DRM+, DVB-T2 Lite or just DIGITAL RADIO?

Some love to talk with abbreviations. They think that talking with abbreviations make them look to know a lot about the subject that they are talking about. Well, looking to know and to really know is absolutely different. To really know a subject, the recipe is the same for all; hard work. It needs many nights without sleep and many hours of talk with experts.  To be honest, I am trying to keep me updated with the latest technology in radio & television, which is not always possible. To be updated one should follow some major events, which are mainly the IBC in Amsterdam, the NAB in Las  Vegas, the DVB World Congress in different cities of Europe and some other events of EBU & ABU. As an amateur blogger it is not so easy to do for me. But, any way God helps and I manage to follow most of them. With luck, the General Assembly (GA) of the Asia Pacific Broadcasting Union, ABU, was in Istanbul this year. I had a presentation on Emergency Warning System at the Technical


Finally, Turkish Radio and Television Corporation, the public broadcaster of Turkey, has officially announced the re-start of the DAB tests in Turkey. At a meeting where the 4K broadcast was announced the General Manager of TRT, Mr. Şenol GÖKA, has declared their interest in DAB.  There is also an article in a magazine of TRT Radio , in which the details of the tests are explained.  I hope that this tests will be the first steps for a digital radio in Turkey. 

post IBC 2015: Digital Radio

There has been a debate on the standard of the digital radio all over the world. WorldDAB & DRM are the two leading non profit organisation to support their solutions; DAB+ & DRM+. There is also another alternative with radio over DVB-T2 Lite profile. During IBC 2015 all three tried to convince the attendees that their solution was the ONE.   The panel of WorldDAB  Mr. Kenneth Wenzel, showing the digital radio over DVB-T2 Lite profile  Head of WorldDAB, Mr. Patrick Hannon Actually I should admit that I did not have chance to attend any DRM event. Although I promised to attend & I shared their program on this blog, I totally forgot this. I had the chance to meet with Mr. Kenneth Wenzel again, with whom I first met at the Levira's event in Tallinn in 2013. I also found chance to chat with the CEO of DVB Project, Dr. Peter Siebert & Head of DigiTAG Mr. Simon Fell & Deputy Head of DigiTAG Mr. Stan Baaijens. We had a meeting with the WorldDAB sta

Eureka! Online magazine from WorldDMB

If you are interested in digital radio, then you will love Eureka!, the e-magazine from World DMB. It is not so frequent as a blog, but it gives you a quick update from the globe. According to the latest issue of the magazine Norway, will be the first country in the world to close down the analog FM broadcast. It seems that Switzerland will be the second. If you look at the GDP per capita, you can claim that this is not a coincidence.  According to the World Bank data, the GPD per capita of Norway is 97363 USD, and Switzerland is 87.733 USD.  You can have a look at the Eureka! . 

e-Interview with Patrick Hannon, President of WorldDMB

It is my honor to post this e-Interview with Patrick Hannon, the President of WorldDMB.  There are many examples of digital radio transitions all over the world. Some are great success whereas some are total fail. I think there is not a one-right-path to follow. What do you recommend us, I mean Turkey, with all those experiences? Digital radio is established in a growing number of markets.  The earliest markets -  UK, Norway, Denmark and Switzerland - have been followed by successful launches in Australia (2009), Germany (2011), Netherlands (2013) and Italy (2014). Recently, Norway became the first country in the world to announce a firm date of Digital Switchover (2017) and Switzerland plans for DSO in 2020-24.  In all of these countries, DAB / DAB+ is the chosen standard.   Whilst every country is different, there are a number of common factors, which underpin success: A consumer proposition which is superior to FM – e.g. greatly improved sound quality, ad

It is my pleasure to announce an e-interview with President of WorldDMB

It was February 2014 when I first met with Mr. Patrick Hannon. Beside his professional carrier as a VP at Frontier Silicon , he is also the President of WorldDMB , the non-profit organization  is the global forum for digital radio, facilitating the adoption and implementation of digital broadcast radio based on DAB, DAB+. We have met in Paris, at the French Radio Days event.  I am honored to announce that Mr. Hannon accepted my e-interview offer. I will send him questions and post his answers. As you may well know, nowadays there is a digital transition in radio market. It is not as fast as television, but it progress. In some countries it is faster than others. Norway announced 2017 for the date of FM Switch Off. UK was the first to start DAB. Germany is an example of unsuccessful DAB and also restart of digital radio with DAB+. To put in a nutshell, there are different trials all over Europe.  Turkey, is an other example. Many do not know but in Turkey we also had Digital Aud

no change in DTT in Turkey

It has been quite a while since my last post. Unfortunately reason for this is not me. After three major election in two years time, I hope that some progress will happen. The only news to announce is that some changes have been made in the Act of RTUK. With these changes RTUK has the right to organise a new tender for DTT frequencies. In the digital radio side things are more complicated. FM frequencies have not tendered yet. FM broadcasters are waiting for a FM frequency tender, which will cause new problems. There are more than 100, yes hundred, FM radio stations in İstanbul. After a tender nearly half of these will loose their frequency. DAB/DRM battle is continuing in which DAB seems to be more lucky.

iTVF digital radio day

Day 2 of iTVF event hosted an important discussion: digital radio standard. There were important presentations from WorldDMB , Digital Radio Mondial e, EBU , RadioDNS and Sony . Session started with the key note speech of Mr. Taha YÜCEL, deputy chairman of Supreme Council of Radio & Television. He addressed some legal issues regarding the transition period from analogue to digital in radio broadcasting.  It may not be quite clear for some that 3G / 4 G or WiMax can not replace broadcast. Let me try to explain this a little more. Technologies of cellular phones or WiFi depends on unicast streams. Where each and every user / consumer sends a request to the server and a unique stream starts from server to the consumer. It is one - to - one type of service.  In the broadcast world however things occur differently. Service is send from the transmitter (like the server in unicast world) to the air. All consumers get the same if they are in the coverage area of the signal. This typ
