アプリケーション例
光ファイバー機器の伝送距離を計算する(英）
One of the many advantages of fiber optic transmission is that it can transmit video, audio, and data over much farther distances than traditional coax cable and twisted pair wire. The exact distance that can be supported by any given system is a...
短距離の光ケーブルを使う上での注意すべき事柄(英）
It is occasionally desirable to connect very short lengths of optical cable between fiber optic transmission modules for specific applications such as high voltage isolation systems, when traversing secure or hazardous environments or for simple...
光ファイバーでデータ伝送ループを構築する(英）
In many data transmission applications it is often desirable to configure a loop, ring-type or drop-and-repeat data bus in order to allow a master or host controller to talk and/or listen to various local slave units. When these units are located...
オーディオ信号のバランスドとアンバランスドを理解する(英）
When designing a distribution system for audio, one of the first determinations that an installer must make is whether the system needs to support balanced or unbalanced audio. While, in theory, all audio signals may be transmitted in either a...
システム損失の"dB"の概念を理解する。（英）
One of the specifications used when describing a fiber optic transmission system is the allowable system loss, measurable in a unit called dB (decibels). In simple terms, this specification describes the maximum percentage of signal strength...
VGA用4チャンネルスイッチをアクセスコントロールに使う (英）
Access control technology is one of the key segments withing the security market. Typically, a standard PC serves as the engine for these types of systems. In many cases, a single property will have more than one access control system installed,...
プロトコール変換にユニバーサル・データトランシーバーを使う。 (英）
In a fiber optic data transmission system, it is sometimes necessary to convert from one protocol into another so that different types of equipment may talk to each other. When converting from RS-232 into RS-422 or RS-485, for example, external...
セキュリティーにおけるコンピュータービデオとビデオスプリッター (英）
Computer video splitters (sometimes called distribution amplifiers) can play a valuable role in expanding the use of computers in security and surveillance operations. Increasingly, PCs of all types are being used for monitoring purposes and to...
コンピューター映像をビデオに変換するスキャンコンバーターをセキュリティーに使う (英）
Security and surveillance environments today often make use of personal computers (PCs) for monitoring and displaying the status of access control systems and alarm conditions. Often times, these PCs are located in remote locations, such as equipment...
Deuce® Proビデオスケーラーをシステムスイッチャーに使う (英）
A common requirement for many professional A/V installations is the ability to use a single display device to show a variety of normal, standard definition TV signals (SDTV) and computer sources. The ability to easily control the switching between...
Deuce® ビデオスケーラーをディスプレーのネイティブ解像度に合わに使う (英）
Unlike CRT-based displays, all LCD/DLP/Plasma (PDP) type projectors and displays have a set number of pixels that comprise the display area. This number of pixels, displayed in either in a 4:3 or 16:9 widescreen aspect ratio, is known as the displays...
Deuce® ビデオスケーラーをビデオキューブとビデオウォールに使う (英）
The Video Wall, an increasingly popular form of large-screen display, is actually a collection of smaller, rear screen video projection cubes, typically configured in a grid pattern (2x2, 3x4, 4x5, 6x8 etc.). These cubes feature either CRT, LCD or...
Deuce® ビデオスケーラーをテレビ会議に使う (英）
Over the past several years, videoconferencing has increasingly replaced face-to-face meetings as an effective means for businesses, municipalities, schools and medical facilities to hold conferences between several facilities located in distant...
Deuce® ビデオスケーラーをホームシアターでCRTプロジェクターのスイートスポット合わせに使う (英）
Despite advances in LCD / DMD type technologies, CRT projectors remain the preferred technology for home theater video displays due to their ability to produce a smooth, natural image. A major problem with home theater installations is that the large...
Fiberlink® 10チャンネル・ビデオマルチプレクサーを使う (英）
In Intelligent Transportation environments, there is often a need to transmit multiple video signals from one location to another distant location in a reliable and cost-effective manner. For example, clusters of cameras may be located at...
Fiberlink® の SDI信号を放送設備で使う (英）
Serial Digital Video (SMPTE 259, CCIR 601) signals are being used with increasing frequency within broadcast facilities as this format maintains signal quality through multiple video processors and multiple generations of recording. For broadcasters,...
VGA用4チャンネルスイッチQuadSwitch®を科学検査コントロールに使う (英）
Many of the new cameras used in todays scientific and inspection control applications have VGA (progressive scan) outputs. These cameras allow the user to capture much finer detail than a typical video camera would. This TECHnique describes how...
Scan Do® スキャンコンバーターをユーザビリティラボで使う (英）
Usability labs are designed to evaluate the ease of use, effectiveness and ergonomics of computer software and hardware. When studying software usability, researchers typically examine issues such as whether a programs human interface is intuitive by...
Scan Do® スキャンコンバーターをテレビ会議に使う (英）
The videoconferencing market has grown exponentially over the past 5 years, allowing more and more face-to-face meetings to be held across long distances without the expense and hassle of travel. One reason videoconferencing has proven to be such an...
Scan Do® Select を公共情報メッセージシステムに使う (英）
Multimedia software has had a dramatic effect on the way in which information is communicated via public messaging systems. Affordable and relatively easy-to-use programs, such as PowerPoint, Scala and Macromedia Director, allow for text,...
