A method for concealing effects of errors in a decoded visual dynamic range combination stream, the method comprising: receiving a decoded VDR combination stream, the decoded VDR combination stream comprising a reference picture unit stream in correspondence of a plurality of RPU frames and one or more video content streams (102, 106) in correspondence of a plurality of video content frames, wherein an RPU frame contains frame by frame composing parameters used by a codec to reconstruct an original VDR signal; receiving a reliability flag (112, 114, 116) in correspondence of an erroneous or missing current RPU frame, or content frame; determining, via the reliability flag, an erroneous or missing current RPU frame; when an erroneous or missing RPU frame is determined, obtaining a lookup table for a nearby previous correct RPU frame and for a nearby next correct RPU frame by passing through all possible codeword values and the corresponding reconstructed VDR output values, under consideration of the bit-depth of the corresponding reconstructed VDR image, characterized in calculating a lookup table similarity metric to measure the similarity between the LUT of the nearby previous correct RPU frame and the nearby next correct RPU frame, wherein a metric value of zero corresponds to a maximum similarity and a higher metric value corresponds to less similarity; based on the calculated lookup table similarity, assigning (202a, 204a, 204b, 202b) a replacement LUT to the current erroneous or missing RPU frame, wherein the replacement LUT is one of: a) a LUT (202a, 204a) of the nearby previous correct RPU frame, b) a LUT of the nearby next correct RPU frame, and c) a bi-weighted interpolated version of a) and b), and if the calculated LUT similarity metric is zero, then assigning the replacement LUT of a); if the calculated LUT similarity metric is smaller than a threshold value, then assigning the replacement LUT of c), if the calculated LUT similarity metric is larger than or equal to the threshold value, then based on calculating a content similarity of a current content frame with a nearby previous correct content frame and a nearby next correct content frame, assigning the LUT of a) or b) according to the content similarity of the current content frame and the nearby previous correct content frame and the nearby next correct content frame, and reconstructing a current VDR image using the replacement LUT. receiving a decoded VDR combination stream, the decoded VDR combination stream comprising a reference picture unit stream in correspondence of a plurality of RPU frames and one or more video content streams (102, 106) in correspondence of a plurality of video content frames, wherein an RPU frame contains frame by frame composing parameters used by a codec to reconstruct an original VDR signal; receiving a reliability flag (112, 114, 116) in correspondence of an erroneous or missing current RPU frame, or content frame; determining, via the reliability flag, an erroneous or missing current RPU frame; when an erroneous or missing RPU frame is determined, obtaining a lookup table for a nearby previous correct RPU frame and for a nearby next correct RPU frame by passing through all possible codeword values and the corresponding reconstructed VDR output values, under consideration of the bit-depth of the corresponding reconstructed VDR image, characterized in calculating a lookup table similarity metric to measure the similarity between the LUT of the nearby previous correct RPU frame and the nearby next correct RPU frame, wherein a metric value of zero corresponds to a maximum similarity and a higher metric value corresponds to less similarity; based on the calculated lookup table similarity, assigning (202a, 204a, 204b, 202b) a replacement LUT to the current erroneous or missing RPU frame, wherein the replacement LUT is one of: a) a LUT (202a, 204a) of the nearby previous correct RPU frame, b) a LUT of the nearby next correct RPU frame, and c) a bi-weighted interpolated version of a) and b), and if the calculated LUT similarity metric is zero, then assigning the replacement LUT of a); if the calculated LUT similarity metric is smaller than a threshold value, then assigning the replacement LUT of c), if the calculated LUT similarity metric is larger than or equal to the threshold value, then based on calculating a content similarity of a current content frame with a nearby previous correct content frame and a nearby next correct content frame, assigning the LUT of a) or b) according to the content similarity of the current content frame and the nearby previous correct content frame and the nearby next correct content frame, and reconstructing a current VDR image using the replacement LUT.
