NHK Science & Technology Research Laboratories

NHK Science & Technology Research Laboratories 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 NHK Science & Technology Research Laboratories rather than just read about it. In short: NHK Science & Technology Research Laboratories (STRL, Japanese: NHK放送技術研究所, romanized: NHK Hōsō Gijutsu Kenkyūjo), headquartered in Setagaya, Tokyo, Japan, is responsible for technical research at NHK, Japan's public broadcaster. Work done by the STRL includes research on direct-broadcast satellite (BS), Integrated Services Digital Broadcasting, high-definition television, and ultra-high-definition television.

Key takeaways

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

Reference excerpt

NHK Science & Technology Research Laboratories (STRL, Japanese: NHK放送技術研究所, romanized: NHK Hōsō Gijutsu Kenkyūjo), headquartered in Setagaya, Tokyo, Japan, is responsible for technical research at NHK, Japan's public broadcaster. Work done by the STRL includes research on direct-broadcast satellite (BS), Integrated Services Digital Broadcasting, high-definition television, and ultra-high-definition television. On May 9, 2013, NHK and Mitsubishi Electric announced that they had jointly developed the first High Efficiency Video Coding (HEVC) encoder for 8K Ultra HD TV, which is also called Super Hi-Vision (SHV). The HEVC encoder supports the Main 10 profile at Level 6.1 allowing it to encode 10-bit video with a resolution of 7680 × 4320 at 60 fps. The HEVC encoder has 17 3G-SDI inputs and uses 17 boards for parallel processing with each board encoding a row of 7680 × 256 pixels to allow for real time video encoding. The HEVC encoder was shown at the NHK Science & Technology Research Laboratories Open House 2013 that took place from May 30 to June 2.

Worked examples

Example 1 — a first encounter with NHK Science & Technology Research Laboratories

Start with the simplest possible case. Write down what NHK Science & Technology Research Laboratories 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 NHK Science & Technology Research Laboratories 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 NHK Science & Technology Research Laboratories 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 NHK Science & Technology Research Laboratories

In research: NHK Science & Technology Research Laboratories 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 NHK Science & Technology Research Laboratories 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: NHK Science & Technology Research Laboratories is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930 establishments in Japan, Audio engineering, Engineering research institutes, so understanding it makes those chapters shorter.
In everyday life: Look for NHK Science & Technology Research Laboratories 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.
