20090052728 | Method and device for displaying images - The present invention relates to a method and a device for displaying images aimed at combating the copying of images by filming during their display, for example by a camcorder in a cinema hall. It is known to modulate the luminance of the pixels of a pattern around the value to be displayed at a high frequency which renders the pattern invisible to the human eye but which generates artefacts on the sequence shot by the camcorder. This pattern is commonly called an anti-copy pattern. According to the invention, it is proposed to increase the hindrance generated by this modulation by varying the amplitude of the modulation of the pixels of the anti-copy pattern as a function of their membership or non-membership in a zone of interest of the sequence. | 02-26-2009 |

20120150849 | METHOD FOR SELECTING VERSIONS OF A DOCUMENT FROM A PLURALITY OF VERSIONS RECEIVED AFTER A SEARCH, AND RELATED RECEIVER - The present invention pertains to a method for selecting a version of a document. The user inputs an identifier of a document at the level of his receiver connected to at least one communication network, and initiates a search request to receive versions of at least one part of this document. The receiver then receives a plurality of versions of the said document. Each version received is analysed by a plurality of evaluation modules so as to calculate an evaluation value for each version received according to a predetermined criterion. The receiver selects for each of the evaluation modules a version of the document having the best evaluation in respect of this criterion, and displays the identifiers of versions having the best evaluations according to each criterion. The user can then easily select the version for reproduction thereof which best meets a criterion. The invention also relates to a receiver implementing the said method. | 06-14-2012 |
