Independent Broadcasting Authority

Independent Broadcasting Authority is a computer 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 Independent Broadcasting Authority rather than just read about it.

Key takeaways

  • Independent Broadcasting Authority belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Independent Broadcasting Authority to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Independent Broadcasting Authority from memory before moving on to harder problems.

Reference excerpt

The Independent Broadcasting Authority (IBA) was the regulatory body in the United Kingdom for commercial television (ITV and Channel 4 and limited satellite television regulation – cable television was the responsibility of the Cable Authority) – and commercial and independent radio broadcasts. The IBA came into being when the Sound Broadcasting Act 1972 gave the Independent Television Authority responsibility for organising the new Independent Local Radio (ILR) stations. The Independent Television Commission formally replaced the IBA on 1 January 1991 in regulatory terms; however, the authority itself was not officially dissolved until 2003. The IBA appointed and regulated a number of regional programme TV contractors and local radio contractors, and built and operated the network of transmitters distributing these programmes through its Engineering Division. It established and part-funded a National Broadcasting School to train on-air and engineering staff.

Approach

The IBA's approach to regulation was more robust than that of its successors, and it assumed the ultimate role of the broadcaster (whereas today, TV licensees are termed "broadcasters in their own right"). The IBA took a very "hands-on" approach and placed the interests of the viewer before anything else. For example, if two ITV licensees wanted to merge, or another wanted to change its broadcast name, this would require approval by the IBA. This direct approach also extended to programmes; the IBA could (and did) place limits on how many soap episodes could be shown per week, if they believed programme quality would be compromised. As well as setting guidelines on advertising content (some guidelines only, the remainder being the responsibility of the ASA), quantity and timings, the IBA also operated monitoring systems for the quality of programme content and the technical quality of programme play-out. On 19 January 1972, the British government announced the lifting of all restrictions and limits on the number of broadcasting hours per day that both the BBC and ITV could air. Until 1972, both the BBC and ITV were limited to how many normal programming hours they could air during the course of each day – by 1971 it was limited to 8 hours per day, with exemptions for schools, adult educational, religious programming, state occasions and outdoor sporting coverage. For ITV this meant they could start a proper daytime television schedule, allowing the smaller ITV companies to produce and sell programming to the network. The IBA ensured that along with the new daytime schedules which launched on Monday 16 October 1972 that their public service remit programming would continue after the restrictions were lifted. Schools programming were now placed in a new 2.5 hour slot each weekday from 9.30am along with the continued production of religious programming and adult education. There were also limits on the value of prizes that could be given away – this dated from the broadcast of the UK version of Twenty-One in 1958 in which a contestant won enough money to buy both a car and a house. In 1960, two years after the quiz show scandals in America, the Independent Television Authority (predecessor of the IBA) imposed a £1,000 cap on the value of prizes which increased to £1,250 during the late 1970s with an occasional limit of £2,000 which rose to £2,500 by 1981. From 1981 to 1988, weekly winnings could average no more than £1,750. On occasion, said limit could increase to £3,500 over a course of four weeks. From 1989 to 1992, weekly winnings could not average more than £5,000 per individual contestant or £6,000 in total winnings per week. British versions of popular American quiz shows had to be adjusted – The $64,000 Question having a maximum prize initially of 64,000 sixpences (£1,600) in the late 1950s, and in the early 1990s of just £6,400. "The Six Thousand Four Hundred Pound Question" was only asked every other week, so as not to break the regulatory £6,000/week maximum. The Independent Television Commission abolished such limits in 1993. Throughout its history until just before its demise, the IBA put out a short weekly programme under the title Engineering Announcements, transmitted outside normal programme hours, and not otherwise advertised. These provided valuable technical information for members of the radio and television trade. These broadcasts were shown on ITV until May 1983 after which they were shown on Channel 4 and S4C, with the final broadcast taking place on 31 July 1990.

1980 franchise round

Regional programming on ITV was a major concern for the IBA, particularly in the 1980 franchise round. The IBA was determined each franchise provided the best possible local service, so the South of England transmission region was split in two, with the successful applicant required to provide separate news services for the South and South East, while in the Midlands ATV's commitment to regional output in the Midlands had been a long-running issue for the IBA; in 1980, they were allowed to keep their franchise, but with several tough conditions.

Worked examples

Example 1 — a first encounter with Independent Broadcasting Authority

Start with the simplest possible case. Write down what Independent Broadcasting Authority claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Independent Broadcasting Authority 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 Independent Broadcasting Authority 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 Independent Broadcasting Authority

In research
Independent Broadcasting Authority appears in computer 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 Independent Broadcasting Authority 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
Independent Broadcasting Authority is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990 disestablishments in the United Kingdom, British organisations established in 1972, Broadcasting authorities, so understanding it makes those chapters shorter.
In everyday life
Look for Independent Broadcasting Authority 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.
