primary and secondary color calibration (including hue/saturation/luminance controls independently for each)
These can either be in chip form, or as a stand alone unit to be placed between a source device (like a DVD player or set-top-box) and a display with less-capable processing. The most widely recognized video processor companies in the market are:
Genesis Microchip (with the FLI chipset – was Genesis Microchip, STMicroelectronics completes acquisition of Genesis Microchip on January 25, 2008)
Sigma Designs (with the VXP chipset – was Gennum, Sigma Designs purchased the Image Processing group from Gennum on February 8, 2008)
Integrated Device Technology (with the HQV chipset and Teranex system products – was Silicon Optix, IDT purchased SO on October 21, 2008)
Silicon Image (with the VRS chipset and DVDO system products - was Anchor Bay Technologies, Silicon Image purchased ABT on February 10, 2011)
All of these companies' chips are in devices ranging from DVD upconverting players (for Standard Definition) to HD DVD/Blu-ray Disc players and set-top boxes, to displays like plasmas, DLP (both front and rear projection), LCD (both flat-panels and projectors), and LCOS/"SXRD". Their chips are also becoming more available in stand alone devices (see "External links" below for links to a few of these).
