20110113492 | METHOD FOR CONTROLLING THE USE OF A CONDITIONAL ACCESS CONTENT AND MULTIMEDIA UNIT FOR IMPLEMENTING SAID METHOD - The present invention concerns a method for controlling the use of a conditional access content (C | 05-12-2011 |
20120023055 | System and method for multi-source semantic content exploration on a TV receiver set - The present invention refers to the field of metadata enhancement system for broadcast televisions program, in particular to provide to the customer more information about a current, past or future broadcast. It concerns a method to enhance transmitted contents, said method starting from the metadata to populate a knowledge database. This method is based on a iterative process to fetch information from open Internet using as search criteria the result of the previous search. The data in the knowledge database are organized in data triple. According to one embodiment, the iterative process is stops when the returned data are related to another content. | 01-26-2012 |
20130254843 | METHOD FOR CONTROLLING ACCESS TO VISUAL MEDIA IN A SOCIAL NETWORK - A method for controlling access to a visual medium in a social network comprising user units connected to a social network site server associated to a database and a to a distorted visual medium server storing visual media posted by users of the social network. A visual medium is selected by a posting user on a user unit and made available to at least one entitled user of said social network. The posting user defines a list of entitled users to be entitled to access the visual medium, said list of entitled users comprising at least one identifier identifying at least one entitled user, said identifier being associated to a parameter defining an access level to the selected visual medium. The selected visual medium is uploaded to the distorted visual medium server in association with the list of entitled users. The distorted visual medium server stores the visual medium in a memory and applies a distortion effect so as to obtain at least one distorted visual medium degraded according to a predefined degradation level. An entitled user iden tified on the list receives, from the distorted visual medium server, the visual medium distorted according to a degradation level corresponding to the parameter defining the access level associated to the identifier of the entitled user. The distortion effect applied on the original visual medium preferably consists of a scrambling operation performed on the original visual medium to obtain a scrambled visual medium. The access level defines the rights of a user for descrambling the scrambled visual medium into a reconstructed visual medium. Depending on the user access level, the reconstructed visual medium can be a partially descrambled visual medium or a fully descrambled visual medium according to the user access level. | 09-26-2013 |
20130322853 | METHOD TO MARK AND EXPLOIT AT LEAST ONE SEQUECE RECORD OF A VIDEO PRESENTATION - The present invention proposes a method to mark and exploit at least one sequence record of a video presentation played on a multimedia unit, said method comprising the steps of:—during the video presentation, receiving a command from a user to mark a currently displayed video sequence, said command initiating the step of:—creating a sequence record comprising a time index or frame index, allowing to locate the proper part of the video presentation, and a reference of the video presentation, At a later stage, requesting the edition of the sequence record by:—adding textual information which corresponds to the actual sequence,—storing the sequence record. | 12-05-2013 |
20130329971 | METHOD AND DEVICE TO SPEED UP FACE RECOGNITION - Method to customize an application associated with a television experience based on the recognition of users located in front of a display and in the field of view of a camera, comprising the following steps:—an initialization step during which each user is enrolled in a database of a computer system and is defined by a profile referenced by a profile ID and comprising the user name, biometric data and additional personal data,—a finding step during which a wide image, acquired by said camera is scanned to isolate at least one user's faces, to define a marking area surrounding it, to memorize the position of said marking areas,—a matching step to extract the biometric data from said marking area, to match them with the biometric data of the profiles stored in the database, and to assign the detected profile ID with the marking area. While subsequent identification is requested by the application, the following steps are executed—acquiring a wide image with the camera,—extracting the areas of said image according to the marking areas,—extracting for a particular marking area the biometric data of a face,—starting the comparison of the extracted biometric data with the biometric data of the profile ID related to this marking area, and in absence of match, continuing with the other biometric data of the database until one profile is found,—transmitting the found profile ID to the application. | 12-12-2013 |
20140020026 | SYSTEM AND METHOD FOR MANAGING A CONTENT CATALOGUE - The present invention related to the domain of audio/video content distribution, where a catalogue of available content is made available to end users. An aim of the invention is to ensure that the catalogue has a high quality in that a search within the catalogue will have a high probability of yielding a result. The invention provides a method and a system for creating useful links between elements in the catalogue whenever it is deemed that such links be useful. The links between the elements are created either by adding new content to the catalogue or new metadata which can be associated with the new content and existing content in the catalogue. | 01-16-2014 |
20150030154 | METHOD AND SYSTEM FOR SCRAMBLING AND DESCRAMBLING A DIGITAL IMAGE - The present invention refers to a method for scrambling an original digital image into a scrambled image and for descrambling the scrambled image into a reconstructed image. The method firstly comprises a scrambling operation for substituting a plurality of original coefficients by dummy coefficients, while safeguarding the coding format, and for storing the substituted original coefficients with their respective position, as original data into at least two control objects, each control object corresponding to a specific degradation level of the original image. This method secondly comprises a descrambling operation for receiving the scrambled image and at least a part of said control objects, and for using original data derived from a selection of at least one of said control objects, performed on the basis of a user access condition, to obtain the reconstructed image by putting back the original coefficients instead of said dummy coefficients thanks to their respective position. | 01-29-2015 |
