Abstract: 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).

Abstract: This invention provides a process which allows better quality rendering of video on any display. The process proposes encoding, video data and additional data. The additional data includes a change time instant. The change time instant can be used to indicate a change in time of a characteristic luminance. The characteristic luminance summarizes the set of luminances of pixels in an image of the video data. The process includes generating on descriptive data based on the video data and encoding and outputting the descriptive data as additional data.

Abstract: A method is proposed of encoding a change time The change time indicates a change in time of a characteristic luminance of the video data. The characteristic luminance summarizes the set of luminances of pixels the video data. The encoding of the time variation of the characteristic luminance provides a more compact and accurate storage and transmission of content.

Abstract: A system and method of processing video data: produce, on the basis of the video data, descriptive data regarding a variation in a characteristic luminance of the video data, wherein the characteristic luminance summarizes the set of luminances of pixels in an image of the video data, wherein the descriptive data identifies the at least one change time instant, wherein the change time instant indicates a time at which a change of the characteristic luminance occurs; and encode and output the descriptive data.
