    摘要: To allow better quality rendering of video on any display, a method is proposed of encoding, in addition to video data (VID), additional data (DD) comprising at least one change time instant (TMA-1) indicating a change in time of a characteristic luminance (CHRLUM) of the video data, which characteristic luminance summarizes the set of luminances of pixels in an image of the video data, the method comprising: -generating on the basis of the video data (VID) descriptive data (DED) regarding the characteristic luminance variation of the video, the descriptive data comprising at least one change time instant (TMA-1), and-encoding and outputting the descriptive data (DED) as additional data (DD).
