Woo Paik

Woo Paik is a engineering 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 Woo Paik rather than just read about it. In short: Woo Paik or Paik Woo-hyun (born November 6, 1948) is a Korean engineer and inventor. Paik's contributions to digital television have been recognized through numerous awards and honors, and for this reason, he is sometimes referred to as the "Father of HDTV." He is the author of numerous technical papers and co-inventor of more than 25 inventions earning U.S.

Key takeaways

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

Reference excerpt

Woo Paik or Paik Woo-hyun (born November 6, 1948) is a Korean engineer and inventor. Paik's contributions to digital television have been recognized through numerous awards and honors, and for this reason, he is sometimes referred to as the "Father of HDTV." He is the author of numerous technical papers and co-inventor of more than 25 inventions earning U.S. Patents in the area of digital video compression, digital transmission, and digital signal processing. Paik earned his doctorate in electrical and electronics engineering from the Massachusetts Institute of Technology, and his masters and bachelors in engineering degrees from Seoul National University. Most recently, he was president and chief technology officer (CTO) for LG Electronics. Prior to that, he was executive vice president, technology, for the General Instrument Communications Division (later the broadband division of Motorola) until 1996. There, he led the advanced development team that vaulted General Instrument to the forefront of digital television technology. His team developed the DigiCipher HDTV system in 1990, which is the world's first all-digital HDTV system. Paik was inducted into the Consumer Electronics Hall of Fame and the Academy of Digital Television Pioneers, in 2004. He received the Digital Television Pioneers Award from Broadcasting & Cable Magazine in 2000, the Arthur C. Clark Award from the Satellite Broadcasting and Communications Association in 1999, a technical Emmy Award from the Academy of Television Arts & Sciences for his outstanding digital television achievements in 1996 and the Matti S. Siukola Memorial Award from the IEEE Broadcast Technology Society in 1991.

Worked examples

Example 1 — a first encounter with Woo Paik

Start with the simplest possible case. Write down what Woo Paik claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Woo Paik 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 Woo Paik 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 Woo Paik

In research: Woo Paik appears in engineering 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 Woo Paik 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: Woo Paik is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, 20th-century South Korean businesspeople, 21st-century South Korean businesspeople, so understanding it makes those chapters shorter.
In everyday life: Look for Woo Paik 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.
