ISO/IEC MPEG-4 High-Definition Scalable Advanced Audio Coding*

Recently the MPEG Audio standardization group has successfully concluded the standardization process on technology for lossless coding of audio signals. A summary of the scalable lossless coding (SLS) technology as one of the results of this standardization work is given. MPEG-4 scalable lossless coding provides a fine-grain scalable lossless extension of the well-known MPEG-4 AAC perceptual au...

High-definition television and telemetry.

In March 1998, WFAA-TV in Dallas became the first television station in the United States to venture into the future of digital broadcasting. But as the broadcast signal went into the airwaves, medical telemetry units on the 13th floor at nearby Webb Roberts Hospital at Baylor University Medical Center went blank. It was 24 hours before engineers at the television station and Baylor put 2 and 2...

Subjective Assessment for Image Quality in High-definition Television

a) that a number of administrations and organizations throughout the world are currently evaluating high-definition television (HDTV) systems, and that in many parts of the world HDTV broadcasting is likely to become the primary medium of the next century; b) that subjective assessments are a vital element in HDTV system design and selection; c) that Recommendation ITU-R BT.500 outlines general...

Recent Progress and Prospects in Organic Electronics

有機材料は,軽量かつ軟らかく曲げやすいといった 特徴に加え,塗布法や印刷などの低温・簡易プロセス による低価格化への期待が寄せられている.特に,有 機材料を用いた有機電子デバイスの性能向上に伴い, 国内外の研究機関から太陽電池やフレキシブルディス プレイ,電子ペーパー,情報タグ,各種センサなどの研 究が盛んに行われている [1]~[3].例えば,有機エレク トロニクス研究分野では,有機 EL(Electroluminescence)と有機 TFT(Thin-Film Transistor)を用い たフレキシブルディスプレイの実現化をターゲットと して産学連携のもとで研究が推進されている.一方, 実用的有機デバイスの実現のためには,材料,デバイ ス構造,プロセスなどに関して検討を重ねた上で研究 を推進する必要がある.すなわち,有機材料を実用レ ベルのデバイスに応用するには,材料物性の改...
