OAR - (original aspect ratio) - Also called Letterbox format, OAR means that none of the image is clipped or squeezed. Unused parts of the screen are usually black.
SQPB (S-VHS Quasi Playback/S-VHS ET) - Allows a TV/VCR combo to play tapes recorded in S-VHS format. Although the feature does not produce S-VHS resolution, it allows playback of otherwise incompatible Super VHS tapes.
PDA - personal digital assistant. A generic term which could apply to Pocket PCs with Windows CE or Palm OS devices.
Line Art - Artwork that is only black and white, with no other tones included.
GSM - Global System for Mobile Communication: A wireless network system widely used in Europe, Asia and Australia. GSM is beginning to be used more widely in the United States.
HDCP - (High-bandwidth Digital Content Protection) - This is a DVI decryption option. It will decode encrypted programs such as first-run movies. (Its real function is to prevent unauthorized copying of programs.)
Vertical Position Adjustment - Allows you to raise or lower the image on the screen to suit you viewing preference.
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.
