    • Techniques are described that can be used to either compress or expand video. Color compression techniques are described that can be used to compress the wide color gamut content into lower color gamut for inclusion in a baseline layer. Color expansion techniques are described that convert lower color gamut data into wider color gamut format for inclusion in an enhancement layer. Both of the baseline video stream and enhancement layer video streams may be transmitted through a channel or stored in a memory device to be viewed later. Accordingly, both baseline and enhancement video layers are available so that either lower or higher quality displays can be used to display video.
    • 描述了可用于压缩或扩展视频的技术。 描述了可用于将宽色域内容压缩到较低色域以包含在基线层中的色彩压缩技术。 描述了将较低色域数据转换成更宽的色域格式以包含在增强层中的颜色展开技术。 基线视频流和增强层视频流都可以通过信道发送或存储在存储设备中,以便稍后观看。 因此,基线和增强视频层都可用,以便可以使用较低或较高质量的显示器来显示视频。
