“First of all, DVB-T2 is not ready for S.A. It is too expensive.” -
Granted that some at DVB have not wanted to promote an unfinished standard and some have put forward economic arguments that was ‘not up to any acceptable standard’ – more like the talk of an uneducated salesman. But …

Who says it will be expensive in 6-12-18 months time. The same argument has been used against very many changes in this and many other technological areas. But the DVB-T2 decoders are not inherently costly – given the expected chip volumes and Moores Law. The cost of a TV without a DTT tuner and one with a DVB-T2 chip is almost the same – or it will be in a few months time.

The benefit, however, of investing in and operating only 2/3 the number of transmitters can be very large for the broadcasters. The world best SFN features of DVB-T2 can provide huge savings in covering large areas with a limited number of large TX masts.
DVB-T2 has come out with flying colours in all tests. In fact is was so robust, that the BBC and Ofcom chose the 40.2 Mbit/sec mode and not the 36 Mbit/sec mode originally planned.

“2nd, creating jobs” When broadcasters and international salespeople morph into ‘job creation experts’ – beware, The DVB-T2 standard is the closest thing to the Shannon limit and an unlikely place to expect universities to get into as new research areas.
All standards are now ‘just a chip’ on the receiver side. The chosen standard will not allow any more or less job to be created in S.A.

“3rd interest” I don’t know – But for myself I can say that I am writing here for no other reason that I truly believe that the people of S.A. will get a much better end more economical system with DVB-T2.

“4th similarities” This is 100% without any relevance. In terms of RF transmission S.A. is not even similar to itself from East to West , from South to North.
Stop such stupid arguments, you make a fool of yourself.

5th: Economies of scale …. has not….” You do not seems to understand – or do not want to understand – that 500+ million in the EU is a very significant market, Not just because there are 500 million highly paid persons, but also because most have several TV sets and many are of the more expensive models.
The DVB-T/T2 MPEG-4 is the current de-facto HW standard for TV sets in most EU countries. In some countries MPEG-4 is not broadcast, but MPEG-2 only receivers are very rare these days.

“6th: Spectrum efficiency issues are not true” – Oh YES they are. DVB-T2 has a very much better spectrum efficiency than anything else – and ISDB is not even a distant second. MPEG-4 has NO relation to the transmissions technology. It just happens currently to be the best compression standard for mainstream video.

“7th:….This is a long term decision” – Exactly – and this makes short term arguments even more irrelevant.

“10th:” S.A is not a developing country and the DVB is an not ‘for profit’ ORG, It has members and they create standards and share information.
Your arguments around deploying DVB/ISDB in South America will indicate that you know little about the different geography and economy of the countries of South America.

First of all, DVB-T2 is not ready for S.A. It is too expensive. Who understands well, knows that it is not being offered seriously for third world countries and it has not been deployed in S.A. What has been tested in S.A. is the old version of DVB.

2nd, creating jobs in Brazil is unlikely with ISDB-T (probably in China), but creating jobs in Europe (and in China) is very likely with DVB. In fact, Brazilian standard has won all battles against DVB in the third world, wherever it has competed. Main arguments are not only the technical ones, but the opportunities it opens to the local value chain, and that includes South African Universities and software industries. Have a look at what is happening in Argentina.

3rd: European DVB lobbyists have what interests? What are the chances of S.A other than just buying something if you adopt DVB? Give yourself a chance to check what Brazilian “lobbyists” are arguing.

4th: S.A is a country with similarities to whom? Spain? France? Or, Peru, Equador, Brazil, etc… All of these, countries with strong similarities with S.A, also have a great share of the population with access to the free-to-the-air TV, instead of cable TV.

5th: Economies of scale argument is bowshit planted by DVB lobbyists. DVB TV sets or SetTopBoxes do not sell more than ISDB sets. DVB has not reached all the population it claims to have. DBV+MPEG4 (the S.A proposal) has no economies of scale by now. DBV-T2 has no economies of scale at all.

6th: Spectrum efficiency issues are not true. 264QAM trades-off robustness…. too technical.. Better not comment on that but believe me… compression is the key point. ISDB-Tb first introduced MPEG-4 and it is the standard which created the economy of scale for that.

7th: DVB lobbyists are rushing African countries to adopt their standards. DECOM is acting correctly on giving themselves time to rethink what is best to S.A. This is a long term decision (for instance, Color TV was introduced 40y ago).

8th: There is no such ITU pressure. Again, that’s DVB lobby.

9th: No comparison tests were made back in 2006, when DVB “decision” took place. Isn’t it better to do it now?

10th: What kind of help DVB gave to S.A in these 4 years? Why D-TV didn’t start yet? Is DVB giving attention now, just because they realized the threat of loosing not only S.A, but also all the neighboring countries to ISDB-T? Just for the record, Peru and Argentina started transmitting D-TV only 6 months after adoption, with the help of Brazil and Japan. Colombia and Uruguay, who adopted DVB are also struggling in their roadmap.

Let´s stick with DVB-T2!!! This one is the best!!!

DVB-T2 is significantly better than anything else in terrestrial YV broadcasting. Not only is the capacity over 60-80% higher ( in the UK some 66% higher), but the signals are more robust at the same time.
Even if enough spectrum is available the cost of transmission of – say 3 muxes – will be reduce by a third as only 2 DVB-T2 muxes needs to be transmitted to enable the same capacity.

ISDB-T do not even come close.

With much new DVB-T2 equipment available on the UK market the higher prices for DVB-T2 receivers will only last a short while.

This seems to be politics at its worst.

It’s a joke, the government has now shown they don’t know what they are doing after all the investment into DVB-T that has taken place.

What is needed now, is transparency at all levels, and not rush-rush deals.

Should be interesting.

Fortunately this will not affect us as we don’t watch television.

How is that going to affect the consumer?

Brazil is no poster boy when it comes to corruption.

This 11th hour intervention stinks…

Someone has an interest in switching, someone in government will get something out of this!

Lets hope common sense prevails.
