135 SDTV SDTV is an acronym for "Standard Definition Television" that identifies lower resolution systems when compared to High Definition Television (HDTV) systems. SDTV systems use the same 4:3 aspect ratio and 480 scan lines to produce a picture as regular analog television sets, but digital decoding enhanced of the signal, displaying a sharper and crisper picture. SDTV broadcasts are either interlaced (480i) or use progressive scan (480p), the latter method providing the best overall image quality. SECAM An analog color video signal that originated in France, and is used in many other countries, including (but not limited to) much of Eastern Europe, parts of the Middle East and Asia. Like the PAL video standard, SECAM also draws a total of 625 vertical interlaced frames of video at a refresh rate of 25Hz, but uses a fundamentally different way of encoding its colors. The name is an acronym for "Séquential Couleur avec Mémoire," which is French for "sequential color with memory." Shadow Mask In CRT monitors, the shadow mask is a metal plate full of tiny holes that is attached to the inside of the glass screen. It focuses the beams from the electron guns at the back of the CRT. The distance between these holes is called the dot pitch. SmoothVision™ HD SmoothVision™ HD incorporates improved anti-aliasing, anisotropic filtering and 3Dc™ compression features designed to further enhance image quality. Anti-aliasing performance is improved, providing better overall detail and image quality. The enhanced anisotropic filtering ensures sharper and clearer pictures at higher frame rates, and the new 3Dc™ compression technology makes it possible to display higher polygon counts for 3D rendered objects. Specular Highlight The bright, usually small, intense light reflected from a 3D surface with a high refraction value. From the intensity and spread of this highlight users can differentiate between a "hard," smooth surface, such as metal or porcelain, or a "soft," textured surface, such as fabric or skin.
