Abstract:
The inventors realized that representing HDR content using LDR content and HDR residual is not unproblematic. The invention therefore proposes representing HDR content using LDR content, LDR residual and global illumination data, instead. That is, it is proposed a method of encoding an HDR video of high dynamic range together with an LDR video, the LDR video providing a lower dynamic range depiction of the HDR video content, the method comprising using processing means for encoding one video of the LDR video and a further LDR video extracted from the HDR video independent from the other video of the LDR video and the HDR video and predictive encoding the other video using the one video as reference, and lossless encoding global illumination data further extracted from the HDR video. This has the advantage that prediction is more stable and globally optimal predictors are more easily found.

Claim (Index 1):
Method of encoding an HDR video of high dynamic range together with an LDR video, the LDR video providing a low dynamic range depiction of the HDR video content, the method comprising using processing means for\n encoding a first tone mapped version of the HDR video, called a first LDR video, and a second tone mapped version of the HDR video, called a second LDR video which is extracted from the HDR video independently of the first LDR video, predictive encoding the second LDR video using the first LDR video as reference, and lossless encoding global illumination data further extracted from the HDR video.
