    What Is Mastered in 4K?

    Sony Pictures Home Entertainment has released Blu-ray Disc™ movies Mastered in 4K and Optimized for 4K Ultra High Definition Televisions. These Blu-ray Disc movies include the following technologies to yield the greatest possible high definition picture quality, and will upscale to create a satisfying 4K experience:

    • Utilization of 4K movie masters created either from a film source scanned digitally with more than 4K resolution, or shot with 4K digital cameras that provides a more precise and detailed picture.
    • The utilization of x.v.YCC color gamut to the 4K movie master delivers an expanded range of rich color contained in the original source when viewed on a high definition television compatible with x.v.YCC specification.
    • We worked together with Sony Pictures to optimize the algorithms of down-converting 4K movie masters to upscale it with the 4K-Reality Pro Engine, when viewed on a 4K LED TV.
