Techniques for HDR/WCR video coding
Systems and methods are provided for processing high quality video data, such as data having a higher than standard bit depth, a high dynamic range, or a wide or custom color gamut, to be compatible with conventional encoders and decoders without significant loss of quality. High quality data is encoded into a plurality of layers with a base layer having the standard quality data and one or more higher quality layers. Decoding systems and methods may map the base layer to the dynamic range or color gamut of the enhancement layer, combine the layers, and map the combined layers to a dynamic range or color gamut appropriate for the target display. Each of the standard quality and the high quality data may be encoded as a plurality of tiers of increasing quality and reference lower level tiers as sources of prediction during predictive coding.
