Organizations such as the Society for Motion Picture and Television Engineers (SMPTE), the Commission Internationale de l'Eclairage (CIE), the Advanced Television Systems Committee (ATSC), and the International Telecommunication Union (ITU) have established standards for the proper transmission and display of video signals.
Commercially available televisions do not generally conform to those standards, but often possess controls that allow those with the proper training and equipment to greatly improve the quality of image reproduction.
The Imaging Science Foundation (ISF) has promoted the value of good video reproduction and certifies candidates as ISF-trained calibrators in the techniques necessary to bring video displays in line with established broadcast, DVD, and Blu-ray standards.
In 2007 it was redesigned as a standalone Windows program based around a new Calibration Optimization and Reporting Environment (CORE) engine.
Written exclusively using 64-bit double-precision floating point math, the CORE engine outperforms even popular spreadsheet applications for calculation accuracy because it never has to drop to single-precision or integer operations for convenience or speed purposes.
