Hiroshi Yasuda

Hiroshi Yasuda is a astronomy 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 Hiroshi Yasuda rather than just read about it. In short: Hiroshi Yasuda (born 1944) is an Emeritus Professor at the University of Tokyo and works as a Consultant for Nippon Telegraph and Telephone. In the sphere of international standardization, together with Leonardo Chiariglione he founded the Moving Picture Experts Group which standardized MPEG-1 Audio Layer 3, better known as MP3.

Key takeaways

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

Reference excerpt

Hiroshi Yasuda (born 1944) is an Emeritus Professor at the University of Tokyo and works as a Consultant for Nippon Telegraph and Telephone. In the sphere of international standardization, together with Leonardo Chiariglione he founded the Moving Picture Experts Group which standardized MPEG-1 Audio Layer 3, better known as MP3. Prof. Hiroshi Yasuda received his B.E., M.E. and Dr.E. degrees from the University of Tokyo, Japan in 1967, 1969, and 1972 respectively. Thereafter, he joined the Electrical Communication Laboratories of NTT in 1972 where he has been involved in works on Video Coding, Facsimile Network, Image Processing, Telepresence, B-ISDN Network and Services, Internet and Computer Communication Applications. He worked four years (1988–1992) as the Executive Manager of Visual Media Lab. of NTT Human Interface Labs., and served three years (1992–1995) as the Executive Manager of System Services Department of NTT Business Communications Systems Headquarters and became vice president, Director of NTT Information and Communication Systems Laboratories at Yokosuka since July 1995. After serving twenty-five years for NTT (1972–1997) he left NTT to work at The University of Tokyo. From 2003 until 2005 he was acting director of The Center for Collaborative Research (CCR) and is now a Professor at Tokyo Denki University. He is a member of the IT Strategic Headquarters (Japan). Professor Yasuda also served as the International Organization for Standardization's chairperson of ISO/IEC JTC 1/SC 29 (JPEG/MPEG Standardization) from 1991 - 1999. He has served as a guest editor of IEEE Journal on SAC several times, such as Vol.11, No.1. and has served as The Exhibition Chair of 1996 Multimedia Systems Conference sponsored by Computer Society. He also served as the president of DAVIC (Digital Audio Video Council) from 1996 -1998. He has received numerous awards, including the Takayanagi Award in 1987, the Achievement Award of EICEJ in 1995, The EMMY from The National Academy of Television Arts and Science in 1995, the IEEE fellowship grade in 1998 for contributions to the international standardization activities on video coding technologies and the research and development of visual communications and multimedia communications systems, the Charles Proteus Steinmetz Award from IEEE in 2000, the Takayanagi Award in 2005 and The Medal with Purple Ribbon from The Emperor of Japan in 2009. He is a Life Fellow of IEEE, Fellow of EICEJ and IPSJ, and a member of Television Institute. He wrote International Standardization of Multimedia Coding in 1991, MPEG/International Standardization of Multimedia Coding in 1994, The Base for the Digital Image Coding in 1995, The Text for Internet in 1996, The Text for MPEG" in 2002 and The Text for Content Distribution in 2003.

Worked examples

Example 1 — a first encounter with Hiroshi Yasuda

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

In research: Hiroshi Yasuda appears in astronomy 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 Hiroshi Yasuda 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: Hiroshi Yasuda is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, Academic staff of the University of Tokyo, Japanese engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Hiroshi Yasuda 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.
