Abstract

The present disclosure relates to a method and apparatus for adapting video content decoded from an elementary stream to characteristics of a display from at least one type of metadata giving information about said elementary stream. Such a method includes: obtaining (102) additional information (HDR DESCR) indicating the presence of a particular type of metadata; determining from the additional information (HDR DESCR) and the characteristics of the display (EDID) whether said video content of said display (11) is displayable on said display (11); and if said video content decoded from an elementary stream is determined to be displayable, then select (105) processing from said additional information and characteristics of a display , and adapt (106) the video content according to the selected processing.

Description

technical field [0001] This disclosure generally relates to picture / video encoding and decoding. In particular, but not exclusively, the technical field of the present disclosure relates to delivering high dynamic range (HDR) content on displays with different capabilities. Background technique [0002] This section is intended to introduce the reader to various aspects of art, which may be related to various aspects of the present principles that are described and / or claimed below. It is believed that this discussion helps to provide the reader with background information for a better understanding of various aspects of this principle. Accordingly, it should be understood that these statements are to be read in this fashion, and not as admissions of prior art. [0003] Whether still pictures or videos, the capture and display of image content with a dynamic range close to the real scene has been a long-standing challenge. [0004] In fact, human vision has a large degree...
