Reflective - Refers to print material that is viewed with the light on the same side of the image as the viewer.
Chasing Playback™ (Panasonic) - Users can begin watching a program, even while it is still recording that same program.
C-band / Ku-band. - 1. a range of RF spectrum. C-band is app. 4 GHz. Ku-band is app. 12 GHz. 2. Geo-stationary satellites the networks use to acquire and distribute programming to affiliates and cable TV companies. These satellites use C-band and Ku-band frequencies. 3. a consumer service that uses the satellites the networks originally set up for themselves. An 8-foot steerable dish is required. Some channels are free. Others are available by subscription. The digital channel subscription service is called 4DTV.
Simulcast - The broadcast of the same program simultaneously over two or more different systems or channels, such as in HDTV and in NTSC. CRTC regulations require today that broadcasters simulcast much of their schedules.
VSB - " Vestigial side band." VSB is an analog modulation technique used to reduce the amount of spectrum needed to transmit information through cable TV, or over-the-air broadcasts.
Composite Video Inputs - A video signal in which brightness (luminance) and colour (chrominance) are combined into one signal. Composite video inputs and outputs use RCA jacks.
Negative - Film containing a reversal of an image, such that the values of the original are reversed with light becoming dark, and vice versa.
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.
