1. A method for extracting and processing video content encoded in a rendered color space (RGB) to be emulated by an ambient light source, comprising:

  • (1) extracting color information from a video signal (AVS) that encodes at least some of said video content in said rendered color space;

    (2) transforming said color information to an unrendered color space (XYZ) via matrix transformations; and

    (3) transforming said color information from said unrendered color space to a second rendered color space (R′

    G′

    B′

    ) via matrix multiplication so as to allow driving said ambient light source to provide emulative ambient lighting drawn from said video content.
