PSIP data - (Program and System Information Protocol) - This data is arranged as a table with multiple sub-tables. The data identifies the station name, what the sub-channels are, the program name, the following programs, content advisories, language options, and caption options. Some of this data is transmitted as often as 7 times per second.
HTML - HyperText Markup Language. A language used to format web pages.
DVI-HDTV - A pure, high-bandwidth digital connection between home theater components and the television. Adopted by a wide range of industries as an affordable digital interface for premium satellite and cable High Definition content.
EPOC - The operating system of the Symbian platform, which works best with low-power, compact machines and long-running applications. It was developed and licensed by Symbian. See Symbian.
Simultaneous Record and Play - Users can watch previously recorded material on a DVD recorder while recording current material at the same time.
WAP - Wireless Application Protocol; standard that describes display interface for handhelds.
Dynamic Bass Boost (DBB) - A special circuit that helps create realistic bass production. Boosting the bass as much as eight decibels (nearly three times more than normal) allows the sound to be rich at all volume levels.
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.
