Which statement correctly defines Rec.709?

• A. Rec.709 defines the standard color space for HD/SD video.
• B. Rec.2020 defines the standard color space for HD video.
• C. DCI-P3 defines the standard color space for cinema.
• D. sRGB defines the standard color space for web images.

Answer: (A)

Rec.709 defines the color space and encoding used for high-definition television. It specifies the exact RGB primaries, the white point, and the transfer function used to convert between a scene and the video signal, which together establish how colors are represented in HD video. This makes it the baseline standard for HD content. Wider color spaces like Rec.2020 are for UHDTV, DCI-P3 is for cinema, and sRGB is used mainly for web images and computer displays. So this statement correctly identifies Rec.709 as the standard color space for HD video.
