Abstract: A specification defining allowable luma and chroma code-values is applied in a region-of-interest encoding method of a mezzanine compression process. The method may include analyzing an input image to determine regions or areas within each image frame that contain code-values that are near allowable limits as specified by the specification. In addition, the region-of-interest method may comprise then compressing those regions with higher precision than the other regions of the image that do not have code-values that are close to the legal limits.

Abstract translation: 定义允许亮度和色度代码值的规范被应用在夹层压缩过程的兴趣区编码方法中。 该方法可以包括分析输入图像以确定每个图像帧内的区域或区域，其包含如本说明书所指定的接近可允许极限的代码值。 此外，感兴趣区域方法可以包括以比没有接近法定限制的代码值的图像的其他区域更高的精度来压缩那些区域。
