KSTR-DT

KSTR-DT is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand KSTR-DT rather than just read about it. In short: KSTR-DT (channel 49) is a television station licensed to Irving, Texas, United States, broadcasting the Spanish-language UniMás network to the Dallas–Fort Worth metroplex. It is owned and operated by TelevisaUnivision alongside Univision outlet KUVN-DT (channel 23).

KSTR-DT belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect KSTR-DT to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

KSTR-DT (channel 49) is a television station licensed to Irving, Texas, United States, broadcasting the Spanish-language UniMás network to the Dallas–Fort Worth metroplex. It is owned and operated by TelevisaUnivision alongside Univision outlet KUVN-DT (channel 23). The two stations share studios at the Univision Tower on Bryan Street in downtown Dallas; KSTR-DT's transmitter is located in Cedar Hill, Texas.

History

Early history The station first signed on the air on April 17, 1984, as KLTJ-TV (the call letters stood for "Keep Looking to Jesus"). Founded by Eldred Thomas, owner of radio station KVTT-FM (91.7, now KKXT), it originally maintained a religious programming format as an affiliate of the Trinity Broadcasting Network (TBN). In early 1986, Thomas sold the station to Silver King Broadcasting, the broadcasting arm of the Home Shopping Network (HSN). As a result of the sale, the station became an affiliate of HSN in September of that year; this left TBN without an outlet in the Dallas–Fort Worth metroplex for the next five months, until it launched owned-and-operated station KDTX-TV (channel 58) in February 1987. On June 1, 1987, the station changed its call letters to KHSX (standing for "Home Shopping in Texas"). On November 27, 1995, veteran television executive Barry Diller announced that he would acquire the Home Shopping Network and Silver King Communications, which owned HSN-affiliated stations in several other larger media markets. The purchase was finalized on December 19, 1996, ten months after the transaction received approval by the Federal Communications Commission (FCC) on March 11. Two years later in 1997, HSN purchased the USA Network, and renamed its broadcast television subsidiary as USA Broadcasting, as part of a corporate rebranding borrowing from the identity of its new cable channel property. That year, KHSX began carrying a one-hour block of programming from business news channel Bloomberg Information Television (now simply Bloomberg Television) at 6 a.m. daily and added a block of classic children's programs on Sunday mornings.

As an independent station In June 1998, USA Broadcasting launched a customized independent station format, "CityVision", which infused syndicated programming—including a few produced by sister production unit Studios USA that also aired nationally on USA Network—with a limited amount of local entertainment and magazine programs (reminiscent of the format used by CITY-TV in Toronto and more prominently, that station's sister broadcast television properties that became charter stations of Citytv, when CHUM Limited expanded the format to other Canadian markets as a television system in 2002).

On October 15, 1999, the station changed its call letters to KSTR-TV (which were used as part of the station's branding, phonetically pronounced as "K-Star"). Channel 49 adopted the "CityVision" format first adopted the previous fall by Miami sister station WAMI-TV on that date, converting into a general entertainment independent station; HSN programming remained part of the schedule, however it was relegated to two separate blocks, running nightly from 2 to 5:30 a.m. KSTR's initial lineup under the "CityVision" format began to primarily feature a mix of reality shows (such as America's Funniest Home Videos and Real TV), sitcoms (such as Sister, Sister, The Three Stooges, The Andy Griffith Show and NewsRadio) and talk shows during the daytime and prime time, as well as drama series (Knight Rider and The A-Team) on weekend evenings, and movies—under the Star Time Movies banner—during prime time on weekends and on Sunday late afternoons. It also aired USA's original programs (such as Tens—rebroadcast from its Miami sister station WAMI-TV—and Strip Poker), along with the regionally syndicated newscast The News of Texas. It also carried a decent lineup of children's programming on Saturday mornings, including those sourced from the BKN syndication block (such as Highlander: The Animated Series, Mighty Max, Adventures of Sonic the Hedgehog, Sonic Underground, Jumanji, Pocket Dragon Adventures, Beakman's World and Extreme Dinosaurs).

During this period, KSTR served as the official station for the Dallas Mavericks NBA franchise. KSTR also broadcast select Fort Worth Brahmas games from the defunct Western Professional Hockey League. The station also used the "City Vision" ("Your City is Our Studio") bumper cards common with USA-owned stations that had converted to general entertainment independents during this time. The local programming-infused format that was adopted by KSTR-DT and its sister stations in Atlanta and Miami, was originally planned to be expanded to the remainder of USA Broadcasting's stations, with some (such as WHOT-TV (now WUVG-DT) in Atlanta and WHUB-TV (now WUTF-DT) in Boston) having either already adopted or eventually switching to the format. Due to financial problems, in September 2000, USA eliminated half of KSTR's entertainment programming inventory, filling the newly opened time periods with an expanded block of infomercials during the morning and an additional block of HSN programming on weekday mornings from 8 a.m. to noon (later reduced to a three-hour block from 10 a.m. to 1 p.m. by September 2001). The station also reduced its children's programs inventory to a daily half-hour of educational programming (consisting of the reality-documentary series Animal Rescue).

Worked examples

Example 1 — a first encounter with KSTR-DT

Start with the simplest possible case. Write down what KSTR-DT claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to KSTR-DT before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about KSTR-DT ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of KSTR-DT

In research: KSTR-DT appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses KSTR-DT in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: KSTR-DT is common in secondary-school and first-year university syllabi. It links to neighbouring topics ATSC 3.0 television stations, Court TV affiliates, Irving, Texas, so understanding it makes those chapters shorter.
In everyday life: Look for KSTR-DT outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is KSTR-DT in simple terms?

Why does KSTR-DT matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study KSTR-DT?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
