Also called line frequency and expressed in kHz, it is the number of video lines written on the screen everysecond (from left to right). The higher the horizontal scanning frequency, the better the resolution (i.e., thehigher the resolution and/or the higher the refresh rate).RETURN TO TOP OF THE PAGEIINF FileINF file (Information File)Information (INF) files store information in a specific format. The set-up functions retrieve information fromthe INF file to use when performing installation operations. Examples of the type of information stored in anINF file include INI and registry changes, file names, and locations of the source files on source media.Interlaced/non-interlacedInterlaced.The method of writing a picture on the screen by initially writing all even lines and subsequently writing allodd lines of the picture. Result: The complete picture is composed of two interlaced half pictures (or fields).With interlacing, a vertical (or field) frequency of 50 Hz means a picture (or frame) frequency of 25 Hz.Non-interlaced.The method of writing a picture on the screen by successive video lines of the picture so that a full frame iswritten onto the screen in one vertical sweep of the beams. With a non-interlaced display, a verticalfrequency of 50 Hz means a picture (or frame) frequency of 50 Hz. At any given resolution, non-interlacedmodes are preferable to interlaced modes; however, generation of non-interlaced modes is more expensive.RETURN TO TOP OF THE PAGEGlossaryfile:///D|/rita/LF2/LF2/LFa1/multi_manual/english/GLOSSARY/GLOSSARY.HTM (7 of 18) [8/29/2001 2:55:48 PM]
