MMC - Multimedia Card: A tiny memory card that uses flash memory to make storage portable among various devices, such as mobile phones and PDAs.
Quick Set Record (QSR, QTR, XPR) - A one-touch button that allows instant recording for 30, 60 or 90 minutes. This feature eliminates the need to use the programming mode.
Scan - The process of translating a picture from artwork or transparency into digital information. Screen Angles. In half-tone printing, these are the angles at which halftone screens are placed to avoid moire patterns on the final image. The most commonly used angles are - Black = 45 degrees; Magenta = 75 degrees; Yellow = 90 degrees; Cyan = 105 degrees.
Digital-to-Analog (D/A) - Converters Changes digital data from a disc or tape into an analog signal that can be amplified and heard through headphones or speakers.
35mm equivalency - What a digital lens would be equivalent to in terms of a 35mm film SLR camera. Used as a standard for discussing the field of view and magnification power of a lens. In 35mm equivalency, lenses over 50mm are telephoto, whereas lenses below 50mm are wide-angle or fisheye lens. In a digital SLR, a mirror placed in front of the focal plane (where the image sensor sits) bounces the light that comes from the lens upward into a prism and then out the eyepiece. When you press the shutter button, the mirror flips up out of the way so the light can pass to the focal plane.
Fps - Frames per Second. To give the illusion of motion, television actually transmits a series of snapshot pictures referred to as frames. Increasing the frame rate improves motion smoothness and may reduce flicker in some displays. In Canada both analog and digital television transmits 30 Fps.
S-Video Signal - A video-only signal that separates the brightness (luminance) and color signals. Significantly reduces color detail artifacts such as dot crawl and improves performance over RF and composite connections.
16 Base - The 2048 x 3072 pixels image that is scanned and stored on a Photo CD and suitable for digital imaging and desktop publishing applications.
3:2 pull-down - This is the process of converting a 24 frames/sec image into a 30 frames/sec image. Some line-doublers will reverse this process to acquire the original, and then re-perform it.
Aspect Ratio - the ratio of image width to image height. The term may apply to the display device configuration, or the shape of the content being displayed. (See Letterboxing) HDTV uses an aspect ratio of 16 units wide by 9 units high. Conventional television programming and displays are at an aspect ratio of 4 - 3. Digital SDTV programs may aspect ratios from 4 - 3 to 16 - 9, dependant on content and its source (e.g. upconverted NTSC is likely to be 4 - 3).
Comb filter - A circuit in NTSC sets that separates the color information from the brightness information.
Descreening - A feature of some scanners that allow them to eliminate moir‚ patterns that can occur.
Franklin eBookMan - A line of eBook reader and content playing handhelds developed by Franklin.
Hertz (Hz.) - A scale used for measuring the number of cycles per second.
IEEE1394 - High-bandwidth digital connection that uses MPEG-2 compression. Requires a decoder for playback and offers networking capabilities.
Interlaced Scanning - Some HD televisions and most conventional televisions use the "interlace" method of scanning, in which the picture is transmitted and painted on the screen in two passes. In the first pass, every other line is painted and in the second, the lines in between. Some display types, such as LCD, plasma and DLP cannot display directly images transmitted as interlaced signals and must convert them to a progressive format prior to their display.
Sampling - This is the digital process by which analog information is measured, often millions of times per second, in order to convert analog to digital.
Surround Output Level - Allows adjustment of the rear speaker level relative to the front speaker level according to viewing location and individual preference.
