DVD-R - Camcorder write-once record/playback format that records motion video linearly to DVD discs. The ultimate in convenience, a DVD-R disc (once finalized) can be directly inserted and played back on most home DVD players.
DTS - Digital Theatre Sound System. A Dolby proprietary discrete 5.1 channel surround system similar to, but not the same as Dolby Digital AC-3, the DTV standard. DTS is used in cinema presentations and in DVD's.
EPG - Electronic program guide. An on-screen display of channels and program data.
A/V Integrated Amplifier - An audio/video receiver that doesn't have a tuner. This type of receiver is an option when radio access isn't desired.
JAD - Java Archive Descriptor: Provides a condensed version of a J2ME application including information on where the installation file is located. Both JAD and JAR files are needed to install J2ME applications.
IEEE1394 - High-bandwidth digital connection that uses MPEG-2 compression. Requires a decoder for playback and offers networking capabilities.
Focus Free - Camera lenses can be categorized by the way they deliver the focused image to the film. If the lens is carefully formulated and positioned it will be able to produce sharp images of subjects from about five feet away to the horizon with no manual adjustment.
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.
