I believe some mention of the difference between simulcast and simulpost should be made (from Urban Dictionary: Two or more contributors to a message board post so closely together in time that the messages receive the same timestamp.)

In Portland, Oregon, theres a church called city bible church, www.citybiblechurch.org, they use simulcast to have church in 3 different locations.

The speaker will go to one location, and will be broadcast onto the screens at the other 2 churches, live how can we add that? 76.115.141.53 (talk) 03:26, 28 February 2008 (UTC)[reply]

History part

Working in TV for eons, I've never come across this method, other than a brief mention by Howard Cosell about some people turning the sound down on ABC's MNF and listening to CBS's MNF. Some citations and sources would be nice, because otherwise, I'm likely to call the whole thing phony. Apple8800 (talk) 04:54, 14 December 2010 (UTC)[reply]

omg this article sucks

This section was by far the most atrocious. It was called "Other Uses." I think it's a shaggy-dog story ending in an ad. I'm not sure, though. I'm going to blank it in a minute.

IIn America, simulcast most often refers to the practice of offering the same programming on an FM and AM station owned by the same entity, in order to cut costs. With the advent of solid state AM transmitters and computers, it has become very easy for AM stations to broadcast a different format without additional cost; therefore, simulcast between FM/AM combos is rarely heard today. Normally, AM stations broadcast some type of talk format; depending on the population, the format may be ethnic. During National Party rule in South Africa, many programs were dubbed in Afrikaans. The English soundtrack was available on Radio 2000. This could be selected using a button labeled simulcast on many televisions manufactured before 1995.

Radio programs have been simulcast on television since the invention thereof; however, as of recent, perhaps the most visible example of radio shows on television is

WCW Nitro
.

In another case, popular programs will be aired simultaneously on different services in adjacent countries, such as The Simpsons, airing Sunday evenings at 8:00 p.m. (Eastern and Pacific times) on both Fox in the United States and Global in Canada. "Simulcast" is often a colloquial term for the related Canadian practice of simultaneous substitution (simsub).

In sports, simulcasts are when a single announcer broadcasts

play-by-play
coverage both over television and radio. The practice was common in the early years of television, but since the 1980s, most teams have used a separate team for television and for radio.

As all NFL television broadcasts are done by the national networks or via cable, there are no regular TV-to-radio football simulcasts. However, NFL rules require that games airing on cable and satellite networks (ESPN, NFL Network) are simulcast on local over-air TV stations in markets serving the two local teams participating in each game.

Similarly, no current

Rod Hundley (Utah
) were the last NBA team broadcasters to simulcast.

In Major League Baseball, only Vin Scully continues the practice; however, he simulcasts only the first three innings of Los Angeles Dodgers games at Dodger Stadium and other National League Western Division parks.

The practice is most prevalent in the National Hockey League where three teams simulcast:

Simulcasts via

direct broadcast satellites
. Even though the process is not instantaneous, this is still considered a simulcast because it is not intentionally stored anywhere.

(Multiplexing -- also sometimes called "multicasting" -- is something of a reversal of this situation, where multiple program streams are combined into a single broadcast. The two terms are sometimes confused.)

In

horse racing, a simulcast is a broadcast of a horse race which allows wagering
at two or more sites; the simulcast often involves the transmission of wagering information to a central site, so that all bettors may bet in the same betting pool, as well as the broadcast of the race.

The San Francisco Giants simulcast with the Oakland Athletics while playing each other on their respective stations and commercials with a mix of broadcasters from both teams.

On

HDTV, or various other combinations) channels in its place. The primary drawback is the common problem of over-compression (quantity over quality) resulting in fuzzy pictures and pixelation
.

In

videoconferencing
equipment.

In many public safety agencies, simulcast refers to the broadcasting of the same transmission on the same frequency from multiple towers either simultaneously, or offset by a fixed number of microseconds. This allows for a larger coverage area without the need for a large number of channels, resulting in increased

multipath interference
significantly, resulting in what is called simulcast distortion.

With some of the latest Simulcast control equipment for FM radio networks, the distortion experienced is almost in-audible to the human ear. With the introduction of Line Equalisation Modules and Tone Generation Modules, the phasing advance and retard is so well calculated that the distortion is almost entirely averted.

The Tone Generation Module (or TGM) generates a pilot tone at 3300 Hz which is then sampled by the Line Equalisation Module (or LEM) which each channel on each radio high site has 2 of located back at the main control site. This then determines the phase shift in the signal and adjusts the transmission accordingly such that all the overlap areas in transmission are in phase with each other.

International vehicle auction company Manheim Auctions offers simultaneous internet broadcast of its physical auctions via its own Manheim Simulcast technology. This technology enables buyers to see and hear what is happening in the auction hall and then, with the click of a mouse, bid and buy cars, vans or trucks in real-time, competing against other online buyers as well as buyers who are actually in the auction hall.[1] 24.177.123.74 (talk) 08:17, 15 January 2011 (UTC)[reply]

I don't disagree about the quality of the article. I noticed that the mention about public safety in the "other uses" section was terribly wrong a couple of years ago when I was looking for some information about multicast interference. The entire article needed to be rewritten (and still does), but I just fixed the information that was there. I see that it's been further clarified. I guess Electrical Engineers don't like to perform major edits on wikipedia articles? In any case, I think that some of the information in this section is useful (though woefully incomplete) and should be incorporated into an improved article, not deleted entirely.
The ad, however, was a bit much.

Really?

I'm just wondering about this sentence: "Another application is the transmission of the original-language soundtrack of movies or TV series over local or Internet radio, with the television broadcast having been dubbed into a local language." Did that really ever happen? I would think getting an Internet radio stream to synchronise with a television broadcast would be nearly impossible. 86.140.32.192 (talk) 23:38, 24 March 2022 (UTC)[reply]
