Abstract: A method for generating a stereoscopic video stream (101) including composite images (C), the composite images (C) including information about a right image (R) and a left image (L), wherein pixels of the right image (R) and pixels of the left image (L) are selected, and the selected pixels are entered into a composite image (C) of the stereoscopic video stream. All the pixels of the right image (R) and all the pixels of the left image (L) are entered into different positions in the composite image (C), by leaving one of the two images unchanged and breaking up the other one into two regions (R1, R2) including a plurality of pixels and entering the regions into the composite image (C).

Abstract: A method for generating a stereoscopic video stream includes composite images having pixels related to a right and a left image of a tridimensional video content; the pixels of the right and left images are inserted into a composite image of the stereoscopic video stream, all the pixels of the right and left images are inserted in the composite image by leaving one of said two images unaltered and breaking up the other one into regions including a plurality of pixels and entering the regions into the composite image; the composite image has larger dimensions than those necessary to allow the insertion of all pixels of the left and right images, and in the pixels of the composite image left after such insertion a depth map is inserted, whose elements correspond to the pixel depth of the tridimensional content.
Abstract: A method for superimposing images on three-dimensional content, wherein a video stream is received which includes the three-dimensional content and a depth map for superimposing images on the three-dimensional content. Once the video stream has been received, images are superimposed on the three-dimensional content in a position in depth dependent on the superimposition depth map (DM). The superimposition depth map contains information about the depth of the three-dimensional content and is inserted as an image contained in a frame (C) of the video stream. The depth map has a smaller number of pixels than that of a two-dimensional image associated with the three-dimensional content. The invention also relates to devices enabling the implementation of the methods.
Abstract: A method for the recognition of stereoscopic glasses, wherein two images of an environment in front of a screen are acquired from the same point of view. A differential image is then calculated by subtracting one of the two images from the other one, and the presence of two lenses is detected within the differential image. A method is also provided for controlling the display of stereoscopic images by using the method for the recognition of glasses. Also described are the devices allowing the methods to be implemented.
Abstract: A system (1) for displaying a stereoscopic video stream includes a display device (3) for displaying the video stream in a stereoscopic or monoscopic mode. The system also includes stereoscopic glasses (2) for watching in stereoscopic mode the video stream displayed by the display device. The stereoscopic glasses (2) include a sensor (20) which detects the presence of a head when the glasses (2) are being worn, and a transmitter (21) which transmits to the display device (3) a piece of information indicating that the glasses are being worn. The display device (3) receives the piece of information transmitted by the stereoscopic glasses (2) and displays the stereoscopic video stream in monoscopic or stereoscopic mode as a function of the piece of information received.
Abstract: A system and a method for encoding and decoding stereoscopic images are described. A stereoscopic image comprises at least two sub-images arranged according to a first configuration and intended for a user's right eye and left eye, respectively. During the video signal post-production stage, a chromatic code is embedded which in adapted to provide information about said configuration. At receiver level, decoding means (14) are used which are adapted to receive said stereoscopic image, recognise the configuration of said at least two sub-images based on information embedded into said stereoscopic image, and arrange said at least two sub-images according to a second predetermined configuration.
