ITU-R BT.709

ITU-R BT.709 is a set of international standards that define how high-definition TV images should look. It specifies aspects like color space, brightness, contrast, and resolution to ensure consistent and high-quality picture quality across different devices and broadcasts. Essentially, it creates a common "language" so TVs, cameras, and video systems produce and display images that are visually accurate and uniform, facilitating a seamless viewing experience. BT.709 is the foundation for most HD video content and helps maintain color fidelity and image clarity from production to playback.
