    Abstract: L'invention concerne un dispositif de reproduction (21), un dispositif (20) agissant comme une source de services numériques. Elle concerne également une méthode de synchronisation de deux parties d'un service numérique dans un système comprenant un dispositif source selon l'invention et au moins un dispositif de reproduction selon l'invention.
    Selon l'invention, le dispositif de reproduction (21) comprend des moyens pour recevoir des données constituant au moins une partie d'un service numérique provenant d'un dispositif source de services numériques (20), des moyens pour traiter (210) au moins une partie des données reçues, des moyens (211) pour reproduire une sortie d'au moins une partie du service numérique, le temps de traitement et de reproduction des données introduisant un retard dans la sortie des données reproduites. Ce dispositif comprend en outre des moyens de communication (213) pour informer le dispositif source du retard introduit.

    Abstract: According to the invention, the mapping operations are subdivided into two main steps : first, a content-dependent mapping of colors from a source content color gamut into an intermediate color gamut which is common to all images to map, and second, a device-dependent mapping of colors from this intermediate color gamut into the target color gamut.

    Abstract: The method comprises:
    - either a first step of color gamut mapping applied directly to the incoming RGB color coordinates resulting into mapped source coordinates R"G"B" and a second step where these source coordinates are transformed into target coordinates R'G'B',
    - or, a first step where the incoming source coordinates RGB are transformed into target coordinates R"G"B" and a second step of color gamut mapping applied directly to the target coordinates R"G"B" resulting into mapped target coordinates R'G'B'.

    Abstract: Method comprising the steps of:
    - choosing a set of calibration colors within said scene,
    - measuring each calibration color of said set such as to get a set of XYZ to represent each calibration color in the given colorimetric color space,
    - by using said image capture device, capturing calibration colors such as to get a set of Raw RGB values to represent each calibration color,
    - estimating a parametric color transform such that any set of Raw RGB values corresponding to a calibration color is transformed into a set of XYZ values corresponding to the same calibration color,
    - building a color calibration transform by the concatenation of the parametric color transform with an output color transform.

    Abstract: Preferably, seven classes of observers are defined, according to different sets of Colour Matching Functions. By displaying specific colour patches of a classification chart using image display devices (CRT,LCD) having different sets of primaries, and by asking an actual observer to compare his perception of the same colour as displayed on each image display devices, the method according to the invention allows assigning said observer his specific class.

    Abstract: The present invention relates to a method and a device for displaying a sequence of images that makes it possible to prevent any unauthorized copying of the latter. It applies to any type of digital display device comprising a matrix of light cells comprising a number of rows and/or columns of cells greater than the number of rows and/or of columns of pixels of the images to be displayed. According to the invention, to disrupt the illegal copying of sequences of images in cinema auditoria, it is proposed to modify the frame frequency of the displayed images by varying the number of rows and/or columns of cells addressed with a black level for at least two images of the sequence.
