Abstract
A method provides translation of metadata related to enhancement of a video signal according to a first high dynamic range video distribution type into metadata related to enhancement of a video signal according to a second high dynamic range video distribution type. Translation is done between a value of a first metadata set corresponding to a first type of high dynamic range video and a value of a second metadata set corresponding to a second type of high dynamic range video and uses an association that may be stored in a lookup table that is determined according to differences between a test image reconstructed using the metadata of first type and the same image reconstructed using the metadata of second type. A receiver apparatus and a transmitter apparatus comprising the translation method are also disclosed.
