    Abstract: In some embodiments, a method for upmixing input audio comprising N full range channels to generate 3D output audio comprising N+M full range channels, where the N+M full range channels are intended to be rendered by speakers including at least two speakers at different distances from the listener. The N channel input audio is a 2D audio program whose N full range channels are intended for rendering by N speakers nominally equidistant from the listener. The upmixing of the input audio to generate the 3D output audio is typically performed in an automated manner, in response to cues determined in automated fashion from stereoscopic 3D video corresponding to the input audio, or in response to cues determined in automated fashion from the input audio. Other aspects include a system configured to perform, and a computer readable medium which stores code for implementing any embodiment of the inventive method.

    Abstract: An existing metadata set that is specific to a color volume transformation model is transformed to a metadata set that is specific to a distinctly different color volume transformation model. For example, source content metadata for a first color volume transformation model is received. This source metadata determines a specific color volume transformation, such as a sigmoidal tone map curve. The specific color volume transformation is mapped to a color volume transformation of a second color volume transformation model, e.g., a Bézier tone map curve. Mapping can be a best fit curve, or a reasonable approximation. Mapping results in metadata values used for the second color volume transformation model (e.g., one or more Bézier curve knee points and anchors). Thus, devices configured for the second color volume transformation model can reasonably render source content according to received source content metadata of the first color volume transformation model.

    特定于色彩体积转换模型的现有元数据集合被转换为特定于明显不同的色彩体积转换模型的元数据集合。 例如,接收第一彩色体积转换模型的源内容元数据。 此源元数据确定特定颜色体积转换,如S形色调映射曲线。 该特定颜色体积变换被映射到第二颜色体积变换模型的颜色体积变换,例如B rte Zier色调映射曲线。 映射可以是最合适的曲线,也可以是合理的近似值。 将结果映射到用于第二颜色体积变换模型(例如,一个或多个基底曲线拐点和锚点)的元数据值中。 因此,为第二色彩体积转换模型配置的设备可以根据所接收的第一色彩体积转换模型的源内容元数据合理地呈现源内容。
