| 20090167769 | METHOD, DEVICE AND SYSTEM FOR MANAGING STRUCTURE DATA IN A GRAPHIC SCENE - A method is provided for restoring graphic animation content including the following steps: in a receiver terminal; transmitting a request for retrieving the content; and obtaining at least one graphic scene of the content describing at least the spatio-temporal arrangement between the graphic objects of the content. The content further includes at least one function for managing structured data allowing interaction with a database of structured data. The method further includes: querying the database, based on at least one command present in the graphic scene and associated with the functions(s) for managing structured data; obtaining structured data derived from the database; integrating the structured data in the graphic scene; and restoring the graphic scene. | 07-02-2009 |
| 20090305743 | PROCESS FOR RENDERING AT LEAST ONE MULTIMEDIA SCENE - A method is provided for restitution of at least one multimedia scene, having at least two objects, on a display of a radio communication terminal. The method includes: determining an orientation of the display relative to a user; reorganizing the arrangement of the objects constituting the multimedia scene, based on the orientation and on at least one arrangement data present in the scene; and restitution of the reorganized multimedia scene on the viewing device. | 12-10-2009 |
| 20100016026 | METHOD FOR COMPUTING ANIMATION PARAMETERS OF OBJECTS OF A MULTIMEDIA SCENE - A method is provided for creating a multimedia scene including at least one object animation, designed to be reproduced on at least one radio communication terminal. At least one of the animations is associated with a non-temporal animation variable, representing a state of at least one object of the scene, of at least one element of the terminal, and/or a state of at least one associated communication network. The variable provides a time-based function for the animation. A method is also provided for reproducing a multimedia scene comprising at least one object animation, on a radio communication terminal. | 01-21-2010 |

| 20110075842 | Method and System Making It Possible to Visually Encrypt the Mobile Objects Within A Compressed Video Stream - A method and system is provided of protecting at least one part of a video stream or of a compressed video sequence against a violation of the information contained in said stream, said stream being able to be broken down into at least one first type of objects and one second type of objects, the method being applied to a selection of images contained in said video sequence, characterized in that it comprises at least the following steps: analyzing the video sequence in the compressed domain so as to define for a given image N at least one first type of objects to be protected by encryption and one second type of objects, the analysis module which identifies the portions of the image belonging to the first type of objects to be protected sends the motion estimation vectors and the transformed coefficients to the encryption step; determining, according to the breakdown into portions or into groups of portions of the existing image N, those corresponding respectively to the first type of objects to be protected and to the other types; encrypting at least a part of the first type of objects; reconstructing, on the basis of the outputs of the preceding steps, a stream consisting of at least one first type of encrypted objects and other types of objects, to which is added information indicating which objects are the ones that have been encrypted. | 03-31-2011 |
| 20110194688 | Method and System Making it Possible to Protect After Compression the Confidentiality of the Data of a Video Stream During Its Transmission - A method is provided for visually encrypting at least one part of an at least partially compressed video stream or video sequence, it being possible for said stream to be decomposed into a first type of objects and a second type of objects, the method being applied on each of the images contained in a video sequence, including at least the following steps:

| 20110317066 | Interactive System and Method for Transmitting Key Images Selected from a Video Stream Over a Low Bandwidth Network - A method and interactive system for the on-line transmission of a high-resolution video sequence composed of a succession of T images includes a step of selecting relevant images comprising at least the following steps: split each image to be transmitted at the instant t into a number N of zones, for each zone n determined in the previous step, calculate a value representative of the content of said zone, for each image to be transmitted, generate a vector representative of the content of said image containing the values obtained in the previous step, calculate a normalized coefficient of correlation α between the reference vector determined for a previously selected image and that calculated for the current image, make a decision on the selection (or not) of the current image as a function of the value of the normalized correlation coefficient α. | 12-29-2011 |
