An artifact common to fixed-pixel displays
that produces splotchy, distinct sections in what should be gradual gradations of color or shadows. Also referred to as solarization
- Bidirectional high-speed digital video/audio and data interface technology adopted by the Institute of Electrical and Electronics Engineers (IEEE). Unlike other video connectivity standards, FireWire requires software programming to ensure compatibility between devices; the FireWire jack on most DVD recorders, for instance, is programmed to be compatible only when connected to a digital camcorder. FireWire connections between HDTV devices, such as a digital cable box and an HDTV recorder, are controlled by 5C DTCP
copy-protection technology. FireWire is Apple Computer's version of the IEEE 1394 interface and is now administered by a consortium that includes Apple and several other companies; sometimes referred to as i.Link (Sony's name), DISH Wire (by Echostar), and EIA-775.
- Digital televisions that use discrete pixels
to create a picture image, such as plasma, LCD, DLP, LCoS, or any non-CRT display device. In the case of DLP
, for instance, each pixel is represented by one of the hundreds of thousands of tiny mirrors mounted on a DLP chip.
- Video display typically using gas plasma
technology and that measures only a few inches thick. More info
- Measurement of light emitted or reflected from a perfectly diffused surface; used to rate brightness in projection TV sets; the higher the rating, the brighter the picture. One footlambert is equal to the relative reflected light radiated by one candle over a one-square-foot area. This measurement is often misleading and misused on projector spec sheets.
- Frames per second. The number of individual still pictures that pass by every second to create a moving image. Film runs at 24fps, while video, including DVD, runs at 30fps. To compensate for the difference, 2:3 pull-down detection
- Type of TV system in which the picture is projected onto a reflective screen or even a wall. The larger the picture, the more visible the pixels or scan lines and the darker the image. CRT systems use three tubes (red, blue, and green), whereas LCD
uses a single projection lens. More info
