CChrominanceThe colorpart of a television signal, relating to the hue and saturation but not to the brightnessor luminance of the signal. Thus pure black, gray and white have no chrominance, but anycolored signal has both chrominance and luminance. Although imaging equipment registersred, blue and green television pictures are handled and transmitted as U and V, Cr and Cb,or (R-Y) and (B-Y), which all represent the chrominance information of a signal, and the pureluminance (Y).See also: YUV, Y,Cr,Cb, CompositeCIEInternational Commission on Illumination (Commission Internationale de l’Eclairage)is devoted to international cooperation and exchange of information among its membercountries on all matters relating to the science and art of lighting. It is a technical,scientific and cultural, non-profit autonomous organization that has grown out of theinterests of individuals working in illumination. It is recognized by ISO as an internationalstandardization body.See also: X´Y´Z´Website: www.cie.co.at/cieCIFSee Common Image FormatCIFSCommon Internet File System – is a platform-independent file sharing system that supportsrich, collaborative applications over the internet which could be useful for collaborativepost workflows. It defines a standard remote file-system access protocol, enabling groupsof users to work together and share documents via the Internet or within intranets. CIFSis an open, cross-platform technology based on native file-sharing protocols in Windowsand other popular PC operating systems, and is supported on other platforms, so users canopen and share remote files on the Internet without installing new software or changingwork methods.CIFS allows multiple clients to access and update the same file, while preventing conflictswith sophisticated file-sharing and locking semantics. These mechanisms also permitaggressive caching and read-ahead/write-behind without loss of cache coherency.CIFS also supports fault tolerance in the face of network and server failures.In Quantel’s Genetic Engineering teamworking infrastructure, the Sam data server virtualizesmedia on-the-fly to give third-party applications instant access to all stored media usingthe CIFS protocol for no-API, out-of-the-box connectivity.Website: www.microsoft.com/mind/1196/cifs.asp38
