16.1. About the Color Space Converter IP
You can configure this IP to change conversion values at run time using an Avalon memory-mapped interface.
A color space precisely specifies the display of color using a three-dimensional coordinate system. Different color spaces are best for different devices, such as R'G'B' (red-green-blue) for computer monitors or Y'CbCr (luminance chrominance) for digital television.
Color space conversion is often necessary when transferring data between devices that use different color space models. For example, to transfer a television image to a computer monitor, you must convert the image from the Y'CbCr color space to the R'G'B' color space. Conversely, transferring an image from a computer display to a television may require a transformation from the R'G'B' color space to Y'CbCr.
Different conversions may be required for standard definition television (SDTV) and high-definition television (HDTV). You may also want to convert to or from the Y'IQ (luminance-color) color model for National Television System Committee (NTSC) systems or the Y'UV (luminance-bandwidth-chrominance) color model for Phase Alternation Line (PAL) systems.
