YIQ to xvYCC Converter - Color Space Converter

YIQ color space introduction

Also known as the YIQ color space.There are 3 channels in total, Y,range from 0 to 1.I,range from -0.5957 to 0.5957.Q,range from -0.5226 to 0.5226.
Origin: The YIQ color space was specifically designed for the North American NTSC color television standard to accommodate compatibility between color and monochrome television broadcasts.
Primary Names: YIQ color space, where 'Y' represents the luminance component, 'I' represents the in-phase component, and 'Q' represents the quadrature component.
Typically expressed as a triplet, for example: YIQ(0.5, 0.2, 0.3) represents a color with specific luminance and chromaticity.
Usage Scope: Mainly used in the North American NTSC (National Television System Committee) color television broadcasting system. Although less used in modern digital technology, it played a significant role during the era of analog television.
Additionally, the YIQ color space allows old black and white television receivers to receive and correctly display the luminance signal from color broadcasts without interference from the color information.

xvYCC color space introduction

Also known as the xvYCC color space.There are 3 channels in total,Y,range from 0 to 255.Cb,range from 0 to 255.Cr,range from 0 to 255.
xvYCC was developed by Sony and standardized by the International Electrotechnical Commission (IEC) in 2005. It is an expansion over the standard YCbCr color space, designed to support a wider range of colors for high-definition video.
The main name is xvYCC, also known as IEC 61966-2-4 or extended-gamut YCC.
Similar to YCbCr, xvYCC is typically expressed as three component values (Y, Cb, Cr). However, xvYCC uses a signaling method that enables it to represent a broader range of colors. This includes values for Cb and Cr that, unlike YCbCr, can exceed the nominal range of video levels, going below 16 or above 235 in 8-bit terms.
xvYCC is used primarily in high-definition video formats and devices such as Blu-ray players, digital cameras, and HDTVs that support HDMI 1.3 or higher. It allows for more vivid and accurate color representation on capable devices.
xvYCC can display a wider range of color values than sRGB by allowing values that fall outside the typical RGB gamut. It achieves this by using the same color encoding method as YCbCr but permits values in the signaling that exceed the range of the BT.601 or BT.709 color spaces.
