Connector generally used with computers. DB or D have 2 rows of pins (see also HD connector).


Term used to define the computer or display monitors that cannot display TV/Video signals (15 kHz). A Data monitor's starting frequency is of about 31 kHz or more (VGA, SVGA, SXGA, UXGA...).


The Display Data Channel or DDC is a collection of digital communication protocols between a computer display and a graphics adapter that enables the display to communicate its supported display modes to the adapter and to enable the computer host to adjust monitor parameters, such as brightness and contrast.


Logarithmic ratio of two "powers" or "voltage" in term of losses or gains (1/10 of a Bel). It is commonly used in Audio systems: OdB is a gain of unity and -3dB is a gain of 0.7.


Video (TV scan) device that transforms a Composite or Y/C signal into an YUV or RGB baseband, with no change in Horizontal and Vertical frequencies.


see balanced.


Way of coding an analog signal. A Digital signal uses sampledamplitude and Discrete Time Coding manners for example of arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. A DLP or LCD projector uses digital coding for displaying an image (Compare to ANALOG).


Deutsche Industrie Norm. Connector that exists in different versions: 4, 5, 8, etc. pins. The S.Video signal generally uses a 4 pins mini DIN (Y/C) connector. Some computer keyboards use DIN or Mini DIN connectors.


DisplayPort is a digital display interface standard produced by the Video Electronics Standards Association (VESA). DisplayPort is designed to replace Digital Visual Interface (DVI) and Video Graphics Array (VGA). DisplayPort can also provide the same functionality as HDMI but is not expected to displace HDMI in high-definition consumer electronics devices. The DisplayPort signal is not directly compatible with DVI, HDMI, or VGA. It is backwards compatible only one Single Link and never with the Dual Link (For example: DisplayPort to Dual DVI on a Radeon© HD Card). Some graphic cards don’t include few chips for the management of the DisplayPort to HDMI Port or as well the problems in the Multi-Mode management for the resolutions. (DP++ Signal). In this case, an active adaptor is always necessary.


Device enabling the signal connected to its input to be multiplied and amplified. Also enables several display devices to be connected to the same source. Also called BOOSTER or SPLITTER.


see Line Doubler.


Device that converts Hi-Resolution computer graphics into a lower (down) computer format, by changing the Horizontal and vertical Scan rate to then be easily displayed.


Direct Touch Control™. Concept for touch controls with direct access, for fast, easy adjustments. Designed by Analog Way® for some of their products such as Scan Converters, Seamless Switchers,…


High-End Digital Audio encoding for Home Theater applications (compressed Multi-Channel). Designed by Digital Theater Systems®.


Digital Visual Interface; connector & SERIAL data Computer interface which transport 3 separate serial channels @ 8 Bits each (R,G,B)+ 1 separate Clock to sample them; electronic transmission is "differential" mode. - DVI-D: Digital ONLY connector - DVI-I: Digital + Analog RGB(HV) on the SAME connector (additional CROSS shape) - DVI-A: Analog ONLY connector.


A specific feature from Analog Way. Dynamic Fit® is an automatic adjustment of the PIP to fit the image borders (Without black stripes). It’s also an automatic adjustment of the PIP (Aspect ratio) to fit the source image borders during a transition.


Extended display identification data (EDID) is a data structure provided by a digital display to describe its capabilities to a video source (e.g. graphics card, Set-top box. It is what enables a modern personal computer to know what kinds of monitors are connected to it. EDID is defined by a standard published by the Video Electronics Standards Association (VESA). The EDID includes manufacturer name and serial number, product type, phosphor or filter type, timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping data.


European Broadcasting Union, which sets European TV Standards.


Enhanced Definition TV, improved consumer compatible TV.


Enhanced Graphics Adaptor. Standard computer format consisting of 640 x 350 pixels.


Electronics Industries Association, which sets certain communication protocols (RS232).


SDI, HD-SDI, HDMI, DisplayPort or other Digital Technologies can carry variety of data along with the video data, including audio, control, or other information. These data are said to be embedded, as they travel with the primary signal from the source device to the destination.




Electro-Magnetic Interference, noise.


Video (TVScan) interface that converts YUV or RGB signals into encoded modulated Composite or Y/C, with no changes in the Horizontal and the vertical frequencies.


Equalization. Selective amplification (signal restoration) applied to a signal to compensate for high frequency attenuation and other distortions encountered in long lengths of cable.


Method of soft switching between 2 sources. When the first source disappears and the second one appears simultaneously on the screen, it is called the dissolve function.


A gradual fade (dissolve) to another source with an all black transition.


: Federal Communication Commission. U.S governmental agency that manages the EMI/RFI policy.


An optical fiber cable is a cable containing one or more optical fibers. Each end of the cable may be terminated with a specialized optical fiber connector to allow it to be easily connected and disconnected from transmitting and receiving equipment. The fiber optic cable allows very long distances in data communication.


An interlaced TV screen is made up of two fields, each one containing half of the scan lines needed to make one standard video frame (picture). See also FRAME (DV). Used on the Institutional and Hi-Tech Consumer markets.


Visual effect of a picture when the frame refresh rate is too slow (it also looks like a horizontal blinking line).


Video image. In an Interlaced system, 1 video picture frame is made up of 2 fields. In PAL/SECAM standard, a frame is made up of 625 horizontal lines, so 2 x 312.5 lines per field. In NTSC, a frame is made up of 525 horizontal lines, so 2 x 262.5 lines per field.


Full screen image still store / background frame. A full screen still image that can be displayed from memory in conjunction with other LAYERs.


The frame rate is how fast the video generator "rebuilds" the entire screen with a new frame. For PAL/SECAM, the frame rate is 25 Hz and the field rate is 50 Hz. For NTSC signal, it is 29,97 and 59,94 Hz. For computer signals, it is often 50 or 60 Hz. See INTERLACED.


Function for pausing on a specific frame from the live image.


Symbol: Hz. Number of cycles per second in a signal. A cycle is when a periodic signal starts with a certain value and reaches the same value the next time.


File Transfer Protocol. A protocol used to transfer files over a TCP/IP network.
