20090098843 | Method for selecting audio contents received from an audio or audio-visual receiver and receiver selecting the contents in accordance with the method - The present invention relates to a method of selecting sound contents transmitted by transmission channels and received by an audio or audiovisual receiver. A user first selects a received content and starts playback. Then, the receiver automatically searches among the contents transmitted by the transmission channels for a content whose audio parameters have values close to the values of a previously selected content and plays it back at the end of the current content. The operation is renewed each time the current content ends. According to a refinement, the receiver has a memory that makes it possible to offset the playback of the content in time and thus best synchronize the playback of the various selected contents. The invention also relates to an appliance capable of selecting audio contents originating from several channels and having similar audio characteristics, and playing them back automatically. | 04-16-2009 |
20090119591 | Method of Creating a Summary of a Document Based On User-Defined Criteria, and Related Audio-Visual Device - The invention describes a creation method of a summary of an audiovisual document respecting both the criteria defined by the user and criteria helping in the understanding of said summary. The document is first split into sequences, each sequence associated with attribute values and a dependence parameter. The user first selects the first sequences either manually, or according to attribute values. Then second sequences are added according to the value of the dependence parameters. These added sequences enable a better understanding of the summary thus created. According to an improvement, the user introduces a maximum duration for the summary, first and/or second sequences are withdrawn from the summary if the duration of the summary thus created exceeds the introduced duration. The invention also relates to an audiovisual device for the creation and viewing of the summary. | 05-07-2009 |
20090142033 | Device and Method for Time-Shifted Playback of Multimedia Data - The invention relates to a method and a device for time-shifted playback of audio/video data. The device comprises:

20100046909 | Method for Identifying a Document Recorded by a Display, Selection of Key Images and an Associated Receptor - The present invention relates to a method for identifying an audiovisual document. Initially, the user programs the recording in an audiovisual content device with the aim of recording a determined document. Once the recording has been performed, the device detects and displays identifiers associated with shots extracted from the recorded content, each associated shot having at least one determined characteristic. An indication of the probability associated with each shot so that said shot is indeed the shot identifying the start or the end of said document is also displayed. Then, the user introduces a selection command for a displayed identifier, the start or the end of said document being identified by the shot associated with the selected identifier. The invention also relates to a receiver featuring a user interface implementing the method. | 02-25-2010 |
20100085491 | PROJECTION SYSTEM BASED ON METAMERISM - The invention relates to a projection system for displaying at least one visual image based on three primary colours, comprising a signal processing unit for converting said visual image into at least a visual image based on four primary colours, a frequency band being associated to each colour primary, first display means for displaying three first primary colours of said visual image on a screen and second display means for displaying at least the fourth primary colour of said visual image on said screen. According to the invention, the system further comprises optical filtering means that are adapted to enhance the separation between the frequency spectrum of the first three primary colours of the first display means and the frequency spectrum of the at least fourth primary colour of the second display means. Application to anti-camcorder systems. | 04-08-2010 |
20100321512 | METHOD FOR CREATING AND REPRODUCTION OF PANORAIMC SOUND IMAGE, AND DEVICE FOR REPRODUCTION OF SUCH AN IMAGE - The present invention relates to a method to create and reproduce a panoramic sound image. Initially, there is a plurality of images associated with sound sequences, these images are for example taken using a camera, this camera having recorded the ambient sound at the time of taking the photograph. The ambient sound is then filtered to keep only the stationary component. Then, the images are concatenated to form a unique image called “panoramic”, each sound sequence being associated with a part of the panoramic image containing the image associated with this sequence. Finally, the commands are introduced to display the parts of the panoramic image. The command also enables to reproduce continually the stationary component of at least a sound content associated with at least a displayed part of the panoramic image. According to an improvement, the sound sequence is reproduced continually until the introduction of a new command. | 12-23-2010 |

20140143669 | METHOD AND APPARATUS FOR RETRIEVING A MEDIA FILE OF INTEREST - A method for retrieving a media file from a media rendering device with an initial set of media files stored in the device. Each media file has attributed feature values stored in the device and is associated to a graphical element displayed on a display. The position of each graphical element on the display depends on a multitude of the feature values of the associated media file. | 05-22-2014 |
