Talk:Digital terrestrial television in the United Kingdom

message: I have removed the part that said some people wont be able to receive Terrestrial TV after DSO.  This is technically correct - after DSO DTT will only cover 98% of the population.  However, this is exactly the same coverage level as ATT, so having this point doesnt really serve any purpose.

thread_title:  Reception of DTT After Switchover 

message: What is this and when does it broadcast? --Surveyor13 13:37, 10 August 2006 (UTC)
replies: text: Carries software updates, and over night. The DTG site shows what its carrying and when. --Kiand 13:44, 10 August 2006 (UTC)
replies: text: But it isn't a channel - you can't watch it. It is also carried on MUX 1 and B. Therefore I don't think it should be included as a "channel" --Surveyor13 20:06, 10 August 2006 (UTC)
replies: text: I think it should, but maybe a note could be made at the bottom of the article telling people that it does not appear on the EPG? --tgheretford (talk) 20:32, 10 August 2006 (UTC)
replies: text: I think the Engineering Channel should be kept in. The multiplexes are used for more than "standard" channels. Keeping these services in gives specific information of what each multiplex is used for. Also, I think the note mentioned by tghe-retford should be expanded to include a small description of the purpose of this service. RobWill80 23:45, 10 August 2006 (UTC)
thread_title: The Engineering Channel

message: "Five, S4C and S4C2 will move to a public service multiplex at the start of digital switchover, using the bandwidth created by switching from 16QAM to 64QAM mode, so will be transmitted from all 1,154[7] UK transmitters. Multiplexes A, C and D will only be transmitted from the current 80 transmitters after switchover but with higher powered signals (and in 64QAM mode"
After DSO, S4C and S4C will NOT be broadcasting from all 1,154 transmitters in the UK. At the moment, these two channels will only be broadcast inside Wales. Pennywisepeter 15:00, 29 December 2006 (UTC)
thread_title:  S4C 

message: "At each transmitter, three of the analogue transmission channels will be reallocated to a digital multiplex, but at a power level about 10dB less than the current analogue signals." - I removed this sentance as it is not universally true that three analogue channels are reallocated - it varies from transmitter to transmitter.  The 10dB statement while technically correct is misleading in that the received coverage area will typically be as good as or better than analogue even though DTT transmitters are using less electricity (http://www.digitaltelevision.gov.uk/pdf_documents/publications/Digital_SwitchoverTrial_Report.pdf)

thread_title:  Reallocation of analogue channels 

message: I've added a link to a petition which is against the switchoff of the analogue signal, is that okay?-GeorgeFormby1
:I have removed it on the basis of precedent.  If this link is allowed we will end up with links for every other petition on any topic imaginable, including but not limited to provision of space for HD on DTT, turning off analogue early to allow for HD/everyone to receive Freeview, keeping Sky's proposed pay service off DTT, allowing Sky's proposed pay service, taking Mux B off the BBC, moving Film4 to mux 2 so that everyone can receive it post DSO, Reduced licence fees for those with Sky, increased licence fees for those with digital, reinstatement of no pay requirement on Muxes B,C and D, removal of shopping channels, forcing ITV to reinstate the ITV News channel, stripping SDN of its mux licence etc., etc., etc. Pit-yacker 16:23, 7 May 2007 (UTC)
thread_title:  I've added a link 

message: The statements on the page saying that current channels could be converted to Hi-Def without increase in bandwidth is flat out wrong.  For the Hi-Def freeview trial (and for the Hi-Def satellite transmission) a Hi-Def channel at 1080i or 720p was/is taking between 16-24mbps, that's a whole Mux of SD channels at the moment.  Even with new compression technologies a Hi-Def channel would take the space of at least three (and more likely four) existing SD channels.
The chart on this page http://en.wikipedia.org/wiki/H264 will give you an idea of bandwidth requirements for HD, the BBC and C4 have stated they will use H264 level 3.1 - level 4 for their transmissions.  —Preceding unsigned comment added by 86.26.250.158 (talk) 16:26, 28 January 2008 (UTC)
thread_title:  Compression Technologies. 

message: I've marked this page for a cleanup as I believe it has a number of areas for improvement:
*The channel list dominates the article and makes it quite long so I propose splitting into a separate article
*Some of the content strays off-topic and into the topic of another article, eg Top Up TV, statistical multiplexing
*Some of the technical details are out of date (eg the plans for HD)
*There are some dead images that need fixing
*The overall style and tone could be improved
I lack knowledge on the subject to rewrite the whole article, but I am willing to help rewrite the technical section as this is the area I know most about. I agree with the comments above that this section contains some dubious technical claims about HD and is missing key information such as the video, audio and text standards currently being used.
I've never done any major edits to a Wikipedia article before so I will wait for the input from others before doing anything. Woonix (talk) 17:27, 3 September 2008 (UTC)
replies: text: Support Agreed it needs cleaned up and split, it also lacks references. Give me a bit to think the best way forward an i will purpose my idea then see how it goes down with yourself and others--Andrewcrawford (talk) 17:39, 3 September 2008 (UTC)
thread_title:  Clean up / page split 

message: Does anyone have any references for this section, or have previous editors just made the information up? ZanderSchubert (talk) 10:13, 25 December 2008 (UTC)
replies: text: It is all verifiable with references, its just that adding references is something people rarely, if ever do (that's something for the whole Wikipedia community to discuss). It's easy to edit an article but much harder to find and enter references into an article. I may do it later, add references where needed and remove unverifiable text. --tgheretford (talk) 11:20, 25 December 2008 (UTC)
replies: text: I referenced the whole section. I did remove some rumours about the bid TV slot not being renewed which has allowed Discovery to gain a 24 hour slot. All I can find about bid TV's slot not being renewed are discussions on the Digital Spy forums, which would not meet reliable sources to meet verifiability, therefore until sources which are acceptable can be found, I removed that rumour from the article. --tgheretford (talk) 14:27, 26 December 2008 (UTC)
thread_title:  "Future channels" section 

message: The broadcast hours (Not TV programmes) CBBC & CBeebies are (aproximately) 0530 - 1858
The broadcast hours (Not TV programmes) BBC3 & BBC4 are (aproximately) 1858 - 0530
This is taken from the EPG as fresh "This is ..." programme titles as well as the text image for each channel switching on/off at these times

thread_title:  CBBC/BBC3 & CBeebies/BBC4 

message: This is a often incorrectly used and misleading term for a H.222 TS.  I recommend using Transport or TS in place of it in the article.  Multiplexing in tech speak normally refers to the combining of multiple electrical or optical signal pulses into single multiplex pulses by either offsetting by time or interleaving.  Certain tech specs commonly and incorrectly use the word when referring packet data interleaving.  Just as Hz has become inappropriately used for anything relative to a second when it's a measure of electrical pulses in a second.Helmboy (talk) 13:52, 20 November 2013 (UTC)
replies: text: The term 'Multiplex' is that which is quite specifically used by the multiplex operators, the broadcast regulators, and other relevant broadcast authorities in the United Kingdom. Although you may personally disagree, its widespread usage by the official authorities themselves really would seem to make it the correct term to use. Bonusballs (talk) 15:55, 20 November 2013 (UTC)

I have just added archive links to  on Digital terrestrial television in the United Kingdom. Please take a moment to review my edit. You may add  after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add  to keep me off the page altogether, but should be used as a last resort. I made the following changes:
