A method is described for generating a color image composed of a plurality of components (Y, U, V) by starting from at least one depth or disparity map (DM, DM), wherein a first set of pixels of said at least one depth or disparity map (DM, DM) is entered into the luminance component (Y) of said color image, and wherein a second and a third sets of pixels of said at least one depth or disparity map (DM, DM) are entered into the two chrominance components (U, V) of said color image.

Method and device for generating, storing, transmitting, receiving and reproducing depth maps by using the color components of an image belonging to a three-dimensional video stream

A video stream composed of combined video frames having a first resolution and include in their entirety two contents usable through extraction from the aforesaid video frame: a first content belonging to a video stream (F) at a second resolution lower than the first resolution of the frame; and, in the area of the frame formed by the remaining pixels, at least a second content belonging to an information stream (F) having, in the case where it is also a video stream, a resolution equal to or less than the second resolution, where during the fruition of one of the two video streams it is shown full-screen in its entirety, or in the case of a data information stream, data encoded via a set of pixels, the number of which is less than or equal to the number of pixels left free by the first video stream.

A method for generating a stereoscopic video stream () having composite images (C) that include information about a right image (R) and a left image (L), as well as at least one depth map includes pixels from the right image (R) and from the left image (L), and then entering the selected pixels into a composite image (C) of the stereoscopic video stream. The method also provides for entering all the pixels of the right image (R) and all the pixels of the left image (L) into the composite image (C) by leaving one of said two images unchanged and breaking up the other one into regions (R, R, R) having a plurality of pixels. The pixels of the depth map(s) are then entered into that region of the composite image which is not occupied by pixels of the right and left images.

Method for generating, transmitting and receiving stereoscopic images and relating devices

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.

Method and device for multiplexing and demultiplexing composite images relating to a three-dimensional content

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.

Method for combining images relating to a three-dimensional content

A method for generating a digital stereoscopic video stream () includes container frames (C), having information about a right image (R) and a left image (L), wherein, when coding the digital stereoscopic video stream (), at least one metadatum (M) is entered which is adapted to identify a region of a container frame (C) containing only one of the two images (L,R).

Method for generating and rebuilding a stereoscopic-compatible video stream and related coding and decoding devices

A device for receiving and transmitting information in a mobile communication network includes apparatus for making a voice call to a telephone number, a memory area for storing the telephone number and at least one identifier of the mobile network operator to which the telephone number belongs. The device further includes the ability to retrieve the identifier through the mobile communication network. The device can extract the network operator identifier of the called number from a message sent automatically when setting up the voice call. The invention also relates to a communication method for a mobile communication network.

Communication device and method for a mobile communication network

A process for transmitting at least one alarm signal from an alarmed apparatus to a PSAP (Public Safety Answering Point,), through a system composed of a plurality of cooperating apparatuses () includes at least one such alarmed apparatus () and at least one responding apparatus, the apparatuses being equipped at least with memory, a processor and a first radio system for direct reception/transmission, from apparatus to apparatus, of signals and data, and the plurality of cooperating apparatus including at least one apparatus () equipped with components adapted to transmit the alarm signal to the PSAP (). An apparatus is also described which is adapted to implement the above process.

A method for generating a composite image of a stereoscopic video stream includes a pair of a right image and a left image of a scene, the right image and the left image being such that, when viewed by a spectator's right eye and left eye, respectively, they cause the spectator to perceive the scene as being three-dimensional, the method includes the steps of: generating a composite image including all the pixels of the pair of right and left images, defining a grid of macroblocks of the composite image, each macroblock of the grid including a plurality of adjacent pixels, decomposing one image of the pair of right and left images into a plurality of component regions including a plurality of contiguous pixels, processing the component regions in a manner such as to generate corresponding derived regions, the derived regions including at least all the pixels of a corresponding component region and being such that they can be decomposed into an integer number of macroblocks, arranging the non-decomposed image of the pair and the plurality of derived regions in the composite image in a manner such that all the edges of the non-decomposed image and of the derived regions coincide with edges of macroblocks of the grid.
