ATSC - "Advanced Television Systems Committee." Formed to establish technical standards for U.S. advanced television systems. ATSC is now used as the catch-all nomenclature for DTV broadcast standards.
High Quality (HQ) - Includes comb filter plus white clipping circuit and detail enhancer to give sharper picture.
Flat Picture Tube - Incredibly strong, flat glass screen minimizes distortion for pictures with advanced clarity and detail. Edges of the screen are flattened out giving the impression of a larger, better picture.
Component Video Switching - Component inputs on a receiver let you switch between multiple component video sources and is compatible with Progressive Scan Video.
TDMA - Time Division/Demand Multiple Access: A 2G wireless technology allowing wireless channels to be divided into time slots, allowing for more access.
Aperture - The opening within a camera lens system that controls the brightness of the image striking the film. The size of the opening is indicated by the f/number.
Blend - In computer graphics software, the intermediate steps between two objects that are created when the objects are merged together via a specified number of intermediate transformations.
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.
