Abstract: A sequence of 3D VDR images and 3D SDR images are encoded using a monoscopic SDR base layer and one or more enhancement layers. A first VDR view and a first SDR view are encoded with a DVDL encoder to output first and second coded signals. A predicted 3D VDR signal is generated, which has first and second predicted VDR views. First and second VDR residuals are generated based on their respective VDR views and predicted VDR views. A DVDL encoder encodes the first and second VDR residuals to output third and fourth coded signals. A 3D VDR decoder, which has two DVDL decoders and SDR-to-VDR predictors use the four coded input signals to generate a single-view SDR, 3D SDR, single-view VDR, or 3D VDR signals. A corresponding decoder is also described, which is capable of decoding these encoded 3D VDR and SDR images.
