Method and system for mastering and distributing enhanced color space content

摘要

A method and system for mastering and distributing enhanced color space content for different display devices (target color space) having display capabilities beyond that of CRT color space. The content creator(s) establishes base or reference color space and enhanced color space data for each target color space. The enhanced color space data is stored as metadata and transmitted over an enhanced color channel separately from the base/reference color space. Both the base/reference data and metadata are encoded before transmission and decoded on the consumer side either by a separate decoder or a display device having an integrated decoder. In other aspects of the invention, auxiliary data relating to the target color space, such as, for example, brightness, luminance, contrast and other display settings can be transmitted over the enhanced color channel and decoded to control the target color space settings (i.e., display settings). The color adjustment metadata could be included in the auxiliary data or maintained separate from the same depending on the desired implementation.

主权项

1. A system for modifying standard system content that is compatible with a standard display device to obtain content with an enhanced color rendition suitable for an enhanced display device, the system comprising:
a receiver for receiving the standard system content and metadata, wherein the metadata is derived from color space difference between the enhanced display device and the standard display device; a decoder for decoding the standard system content and metadata to obtain decoded standard system content and color space difference; means for receiving and decoding auxiliary data representing colors that are outside of the enhanced display device's gamut; means for converting the decoded auxiliary data into a format compatible with the enhanced display device; and means for combining the converted auxiliary data with the decoded standard system content and color space difference for producing the content with the enhanced color rendition in the enhanced color space; and means for providing the enhanced color rendition content for display on the enhanced display device.
