in the U.S.?[edit]

Why they know it in the U.S.? As logical channel number (as in Europe) or as a "virtual channel"?

Huh? --CFIF (talk to me) 17:47, 5 August 2006 (UTC)[reply]

Question[edit]

Does anyone know if there are any regulations (in the U.S.) on which virtual channels a station can occupy? I know virtually (no pun intended) all stations in the U.S. are mapping virtual channels to their analog equivalents right now, even when they're UHF positions that aren't particularly well liked... just doesn't make sense to me.

add examples[edit]

Please add examples of actual Virtual Channel Tables. Please tell us how to find the VCTs for various locations. Do new tuners allow selection of real channels, virtual channels only, or both? -69.87.203.112 (talk) 01:22, 22 September 2008 (UTC)[reply]

In the UK the LCNs vary according to your provider. For Digital Terrestrial they are the EPG numbers shown at http://en.wikipedia.org/wiki/List_of_digital_terrestrial_television_channels_(UK) . For cable (usually Virgin) and satellite (Sky) some of the numbers differ. French DTT LCNs are at http://en.wikipedia.org/wiki/List_of_television_stations_in_France and Irish DTT's LCNs are at http://en.wikipedia.org/wiki/List_of_channels_on_Saorview . NZ http://en.wikipedia.org/wiki/Freeview_(New_Zealand) . Australia http://en.wikipedia.org/wiki/List_of_digital_television_channels_in_Australia . I don't know about VCTs for the US and Canada, I've often wondered the same myself. 86.160.149.131 (talk) —Preceding undated comment added 15:19, 19 October 2012 (UTC)[reply]

Confusing![edit]

The most common reason for a television station using a virtual channel is to minimize viewer confusion when a digital transmission is airing on a different channel than the one the station used in analog mode

If it weren't for the wikipedia, this would still be confusing me. I got a list of channels and it said CBC HD was on channel 20. Try as I might, I couldn't tune in 20.1, I kept getting channel 5.1. Now I know why.

So while this might indeed reduce confusion in the reverse case, I find this re-mapping to be extremely confusing. DTV channels are listed by their DTV channel number, not their virtual channel. So you type in one thing, get another, and then wonder why.

Non-explanation[edit]

"In Europe, Africa and the Middle East, there is no special numbering system for subchannels, as two related channels may have completely unrelated numbers (for example, in the UK, ITV1 is channel 3 and ITV2 channel 6)." The clause following "as" seems to be the effect rather than the cause. It's certainly not much an explanation. The obvious question is, why does ITV choose to broadcast its channels as 3 and 6 rather than as 3.1 and 3.2? Or is it not a choice but something enforced by the particular system that regulators or technology have imposed on the UK? In which case the "as" should be a "so". 86.177.125.185 (talk)

I can fix that simply by deleting the "as", but note that you're using "channel" in two entirely different senses here, one technical and the other colloquial. Channels 3 and 6 are true channels in the technical sense: ranges of frequencies given the official designations "3" and "6". ITV1 and ITV2 are trademarks or names traditionally associated with channels, but not any more, except in the colloquial sense of the word. You might think of them as "program streams" with names. Unfree (talk) 12:39, 5 December 2009 (UTC)[reply]

It may well be the case that the ITV1 and ITV2 channel numbers are unrelated - that is, that the fact that 6 equals 2 * 3 is mere coincidence. But often the LCNs chosen do have a certain mnemonic quality. ITV4 is 24. More4 is 14. E4 is 28. 86.160.149.131 (talk) 15:10, 19 October 2012 (UTC)[reply]

In Europe there was never any connection between the name of a station and the channel (as in frequency) it is transmitting on. On a European TV or set-top box, pressing the '1' button on your remote does not get you channel 1, but the station *you* set up to be on the '1' button (there is usually some semi standard way of arranging the stations). The transmitting channel (as in frequency) could be anything. Generally, if people in Europe say "The first channel", they refer to the station you have set up to be the '1' on your remote. This reflects historic usage, with "the first channel" being the first TV station to come on air in a given country or area. In Germany, the flagship station of the ARD network calls itself "The first one". That's because it was the first TV station to come on air. It was never transmitted on RF channel 1, plus there isn't even a RF channel 1 (VHF channels in Europe are 2 to 12, and UHF is 21 to 69). — Preceding unsigned comment added by KyleJeevas (talk • contribs) 14:21, 1 September 2019 (UTC)[reply]

"actual radio channel"[edit]

If I'm not mistaken, this is the ordinary meaning of "channel", and can be thought of as "an officially defined and designated range of frequencies", a concept which ought to be introduced very early in the article. Unfree (talk) 12:29, 5 December 2009 (UTC)[reply]

Jargon-fest[edit]

The article starts off with a blast of jargon or acronyms or abbreviations which need to be explained in English or at least Wikilinked in their first usage in the article or even in a section. The following is not at all helpful to the average reader or even to someone with a background in electronics: " DVB extensions such as NorDig or NDS."

Mixed numbered/bulleted lists[edit]

In the section Virtual channel#Usage Examples, there are three lists. Each of them begins with a number, then switches to bullets, like this:

The order for cable provider TimeWarner:

  1. Reserved for subscriber on-demand services
  • Basic subscriber channels are from 30 to 120
  • Extra subscriber channels are from 121 to 199
  • Informational subscriber channels are from 200 to 244

Is this intentional? It looks really bad, but I can't fix it because I don't know what it was intended to mean. (I also can't figure out how "Reserved for subscriber on-demand services" has to do with the rest. Does it mean channel one?) — Lawrence King (talk) 05:56, 4 May 2018 (UTC)[reply]

I cannot help with the first problem. However, "Reserved for subscriber on-demand services" refers to pay-per-view content. This is a service offered by pay-TV and cable operators. You have one or more channels which are normally encrypted. By paying a fee, they get decrypted for you personally, for a short amount of time, allowing you to watch a movie or some other content.
