Abstract

The present disclosure generally relates to a bitstream relative to a video signal characterized in that it carries an information data which identifies an electro-optical-transfer-function intended to be applied on the video signal before rendering the video signal on a video display. The disclosure further relates to a method for generating such a bitstream and a method for obtaining an electro-optical-transfer-function intended to be applied on a video signal before rendering the video signal on a video display.

Description

technical field [0001] The present disclosure generally relates to gamma correction in video signals. 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 disclosure, which are described and / or claimed below. It is believed that this discussion helps to provide the reader with background information to facilitate a better understanding of the various aspects of the invention. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. [0003] figure 1 A block diagram illustrating a complete video processing scheme from the capture of a video signal to its presentation on a display is shown. [0004] In general, the processing scheme comprises: capture means CAPA, by which the video signal VID is captured; display means DISA, which comprise a module RM configured to calculate and display the presentati...
