20110019870 | EMBEDDING INTERACTIVE DATA INTO AN AUDIOVISUAL CONTENT BY WATERMARKING - A method for referencing and interconnecting contents, applications and metadata to an audiovisual content is described, especially for iTV of for distribution on DVD, which comprises the step of inserting a digital watermark into the audiovisual content during an audiovisual content encoding step, the digital watermark being possibly used for allowing a user to reproduce or exploit additional contents supplementing those provided by the audiovisual content, wherein the digital watermark is inserted into the audiovisual content as data frame with header and body by subdividing it into a plurality of consecutive āIā frames and forcing the parity of LSBs of mid-frequency providing an auxiliary watermark channel, e.g. in an MPEG2 transport stream. | 01-27-2011 |
20120281068 | Method for Generating, Transmitting and Receiving Stereoscopic Images, and Related Devices - The present invention relates to a method for generating a stereoscopic video stream ( | 11-08-2012 |
20120307882 | METHOD FOR TRANSPORTING INFORMATION AND/OR APPLICATION DATA INSIDE A DIGITAL VIDEO STREAM, AND RELATIVE DEVICES FOR GENERATING AND PLAYING SUCH VIDEO STREAM - A method for transporting data within a digital video stream, wherein the digital video stream includes information and/or application data not intended for display and at least one frame includes an image to be displayed, and wherein the at least one frame includes a number of pixels which is greater than the number of pixels of the image. The method provides for entering the information and/or application data into pixels of the frame which are not occupied by the image. The invention also relates to a method for playing a video stream that carries information and/or application data within its frames. | 12-06-2012 |
20120320279 | Method for Automatically Programming a Receiver Able to Receive Radio Television signals in at Least Two Different Formats and Related Receiver - The invention relates to a receiver and a method for automatically programming a receiver adapted to receive radio-television signals belonging to a plurality of radio-television networks in at least two different formats, the method comprising the steps of: storing into a first table ( | 12-20-2012 |
20130083160 | METHOD FOR DECODING 2D-COMPATIBLE STEREOSCOPIC VIDEO FLOWS - A method for processing a video stream of digital images includes: receiving the video stream which includes at least one composite frame containing a pair of stereoscopic digital images according to a predetermined packing format; receiving metadata which describes the format of the composite frame; generating an output video stream which can be reproduced on a visualization device, wherein the method further includes the steps of determining the area in the composite frame which is occupied by one image of the stereoscopic pair within the composite frame based on the metadata; extracting the image contained in the area from the composite frame, and generating an output frame containing the extracted image. | 04-04-2013 |
20130135435 | METHOD FOR COMBINING 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. | 05-30-2013 |
20130201282 | METHOD FOR GENERATING AND REBUILDING A STEREOSCOPIC-COMPATIBLE VIDEO STREAM AND RELATED CODING AND DECODING DEVICES - A method for generating a digital stereoscopic video stream ( | 08-08-2013 |
20130229487 | METHOD AND DEVICE FOR MULTIPLEXING AND DEMULTIPLEXING COMPOSITE IMAGES RELATING TO A THREE-DIMENSIONAL CONTENT - 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. | 09-05-2013 |
20130315474 | METHOD FOR GENERATING, TRANSMITTING AND RECEIVING STEREOSCOPIC IMAGES, AND RELATED DEVICES - 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. | 11-28-2013 |
