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. Idf 14:18, 20 April 2006 (UTC)
What is this and when does it broadcast? -- Surveyor13 13:37, 10 August 2006 (UTC)
Anybody know anything about future potential carriage of RSLs after DSO? —The preceding unsigned comment was added by Fursday ( talk • contribs) 07:03, 9 December 2006 (UTC).
"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)
"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) Md84419 23:44, 17 March 2007 (UTC)
"National Grid Wireless bought by Arqiva
National Grid Wireless (the owner of two Freeview multiplexes and the company responsible for the distribution of the BBC’s Freeview and radio services) has agreed to sell its business to Arqiva (the company that broadcasts multiplexes A and 2) for £2.5 billion. Arqiva bought their existing transmission sites from NTL for £1.27 billion back in 2004." - http://www.deeteetee.co.uk/, from http://www.bloomberg.com/apps/news?pid=20601087&sid=amd_Pyqg_IPw .
Question though - the article indicated Arqiva broadcasts muxes A and 2, which are noted as something else in the article. Can we get confirmation on this and then change accordingly...?
I've added a link to a petition which is against the switchoff of the analogue signal, is that okay?-GeorgeFormby1
Can someone please elaborate about the sound capabilites on DTT. I understand that channels currently include only stereo, which may occasionaly be encoded with the analogue Dolby Pro Logic (surround matrix). Do any channels have Dolby Surround II or Dolby Digital 5.1?
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)
I've marked this page for a cleanup as I believe it has a number of areas for improvement:
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)
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)
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

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)
