message: Would this be a good place to add some basic information that s new study group has been launched to look into the future version of DVB-T called DVB-T2? There really isn't much information at the time to justify a new article. 24.80.38.70 18:31, 26 April 2006 (UTC)

thread_title: DVB-T2

message: This article talks about MPEG-2 as the encoding used for DVB-T, however in the UK there are already DVB-T broadcasts using H.264 for HD content. Is MPEG-2 really mandatory to meet the DVB-T specifications, and if not, should references to MPEG-2 be removed from this article? Neilka 09:53, 8 June 2006 (UTC)
replies: text: Yes, you are right. It would be more correct to write that only MPEG-2 TS is mandatory, whereas the audio and video contents can be different from MPEG-2 (e.g. H.264). --Cantalamessa 15:09, 8 June 2006 (UTC)

message: This article is very technical and doesn't actually seem to tell the casual reader precisely what the heck DVB-T actually is or does. Perhaps a re-write is in order?--Commander Zulu 12:39, 27 February 2007 (UTC)
replies: text: Actually, DVB-T is a standard, thus it is inherently technical (I've provided only the technical stuff). Some more "commercial" information could be added at the beginning. or we should redirect more precisely towards digital terrestrial television. --Cantalamessa 13:28, 27 February 2007 (UTC)
replies: text: I agree as well, and there clearly needs to be a mention of resolution. Surely wikipedia is also a resource for normal people, not just technicians. --IceHunter (talk) 18:05, 19 October 2009 (UTC)

message: I think the article is missing a whole section around aerials. We here in NZ are soon to get DVB-T and I had questions around aerials and there are no answers here. Perhaps someone who understands can answer a few basic questions? Are the aerials for DVB-T directional or omnidirectional? If the signal is coming from some location as Analogue TV can you reuse the aerials? If yes is that only for VHF/UHF or both? Imcdnzl 21:33, 19 August 2007 (UTC)
replies: text: Do you already have a standard TV antennta because they are all on the same VHF/UHF frequency. There is no such thing as a 'digital' TV antenna.--Dacium 02:43, 16 November 2007 (UTC)
replies: text:  Surely this is not true, owing to the requirement to receive all multiplexes, which are spread across the spectrum, whereas existing analogue broadcasts (in the UK at least) were allocated to the high, middle or low parts of the spectrum and aerials sold for each (group A, B etc and W). If you are lucky your existing aerial will work fine, but if you have, say, a low-frequency aerial then you may not receive the high frequency multiplex (often the most difficult) at adequate level, and so some channels will be missing. Wide-band aerials generally have lower gain than those optimised for a particular group of frequencies, so you may need a more elaborate one. Also, if an installation includes distribution amps or masthead preamps these often fail to work on digital because they suffer too much intermodulation from strong adjacent analogue channels (again a big problem in the UK). Good quality preamps with low intermod can result in perfect reception where the aerial alone fails totally, but only if they have the right amount of gain so that no analogue channels clip and hence intermodulate. --Lindosland (talk) 16:19, 28 January 2008 (UTC)

message: "It is expected that by 2017 there will enough DVB-T2 equipment to switch all transmissions to DVB-T2 128QAM mode"
The 128QAM mode is speculations. What is known, is that new modulation and new FEC will be used to increase the net bitrate by 'at least 30%' under equivalent conditions.  128QAM will not be in the standard. Reslfj (talk) 21:05, 7 April 2008 (UTC)
replies: text: Can we expect all Freeview transmissions to change to DVB-T eventually, in other words is it compatible so far as existing receivers are concerned (or are they software upgradable)? If it is not, then presumably bandwidth will continue to be wasted long into the future and only new 'HD capable' boxes will receive the improved standard. --Lindosland (talk) 16:09, 28 January 2008 (UTC)

text: Hello Reslfj, ok for the Ofcom plan. I have removed the sentence with "currently", since this is not a wikinews article, but a wikipedia one and should be written in an atemporal way. Moreover, the bold emphasized numerical figures look like some sort of POVvity, thus I think it is better to put them on a lower level of attention. --Cantalamessa (talk) 19:28, 9 April 2008 (UTC)

text: What about moving the section "DVB-T2" in the relevant page DVB-T2? I think we have enough information to do that? --Cantalamessa (talk) 11:12, 10 April 2008 (UTC)

text: Agree. --Cantalamessa (talk) 20:05, 13 April 2008 (UTC)

message: Could someone expand this article about how an end user can recieve them channels and what equipment is needed? I.e. a special antena?  —Preceding unsigned comment added by 195.177.212.225 (talk) 12:21, 3 November 2008 (UTC)
replies: text: The used bands and frequencies are same as in analogue TV. When the signal is strong enough, the home user doesn't need a special antenna. He only needs a DVB-T receiver. Modern TV sets already include DVB-T capabilities, older equipment needs an external (but cheap, it's not that complex and im most countries funded during the transition phase) STB. 193.187.215.11 (talk) 11:29, 9 January 2009 (UTC)

message: Hello, if anyone knows the difrence between DVB-T2 and DVB-T ? And for example, can I watch TV program that is DVB-T2 with DVB-T TV tuner ? Adrian (talk) 22:12, 4 September 2013 (UTC)
replies: text: Of course it's incompatible. They want you to buy new receivers and once DVB-T is switched off, all the non-T2 receivers automagically turn into e-waste. Guess whats going to happen in 10+ years with DVB-T2..?! In fact, in Germany, some TV stations (four IIRC) have decided to stop broadcasting on DVB-T because it's too costly for the "few viewers" (several million!). This turned into a snowball-effect and more and more stations are getting off DVB-T ... They've already begun to make the standard useless/obsolete. Should've stayed with something that.. you know.. works.. and doesn't have any DRM crap (hint: Analog!)  --84.62.150.17 (talk) 12:05, 23 September 2013 (UTC)
thread_title:  Help? DVB-T VS DVB-T2 

message: The 8VSB article has a second talking about differences between ATSC/8VSB and DVB-T/CODFM. However, there is no corresponding article on CODFM, that points to the general article on ODFM which has no DTV-T specific information. This article does have a table with lots of data, but doesn't tell you which of the dozens of possible combinations are actually being used.
So can someone who knows add some text explaining which of the many standards are actually in use for TV broadcast purposes? I suspect its a small subset of the full list. If that's the case, perhaps those selections could be indicated somehow, maybe a different background color in the cells? I notice, for instance, that the UK DTV article has some of these listed, which what appear to be rather high bitrates, which I assume is used to broadcast multiple channels?
I also see some text about the frequency allocations which seems to suggest that DTB-T is generally using more bandwidth than ATSC. If I am reading it correctly, it seems that some are using 8 MHz, some 6, and a few 7. IIRC, PAL used a slightly wider bandwidth than NTSC, 8 MHz including the guard band and some extra space beyond the audio carrier. NTSC used 6 MHz including a similar guard, but lacks the empty space. So am I correct in thinking that the wider allocations are due to the differing bandwidths of the systems they are replacing, NTSC and PAL, respectively? If so, this should definitely be added to the article.
Thanks!
