摘要： A system having an extended display surface that includes a main display surface, associated with at least one screen, and at least one peripheral display surface, associated with a peripheral display element, extending around at least part of the main display surface, and one or more backlighting units configured to illuminate these display surfaces. After receiving a plurality of digital images each represented by an image data array, the system performs an extraction from the image data array, of a main image data array of dimensions equal to the dimensions of the screen, and an extraction or generation of at least one complementary image data subarray, and a control of displaying the main image data array on the screen and controlling the backlighting units to perform a display of each complementary image data subarray on the corresponding peripheral display element.

摘要： A method implemented in an audio system including a transducer having a magnetic element suitable for generating vibrations based on the frequency of the audio signal. The method is implemented by one or more processing chains including: A) a high-pass filtering of the digital audio signal having a frequency greater than or equal to 10 Hz and less than two thirds of the specific cutoff frequency of the transducer; B) performing a first low shelf filtering with a predetermined first amplification gain; C) estimating an excursion value of the transducer for the signal obtained after applying the first low shelf filter; D) if the estimated excursion value of the transducer exceeds the maximum excursion value, calculating a second amplification gain that is less than the first gain; and E) applying a second low shelf filtering of gain equal to the second calculated gain.

摘要： An audio processing method and system for a seat headrest audio system, the audio system including at least two speakers positioned on opposite sides of the headrest, the method including detecting a position of the user's head and adjusting a first set of parameters of at least one audio processing operation as a function of that position. The method includes determining a user characteristic and/or temporary state of the user, selecting an audio settings profile related to that characteristic, the audio settings profile including a second set of prerecorded audio profile parameters, and adjusting a third set of audio parameters effectively applied to control the audio rendering of each speaker, based on the first and second sets of parameters.

摘要： An audio system for a headrest having a set of R right speaker(s), a set of L left speaker(s), and an electronic chain configured to emit a sound signal from at least a right input signal and a left input signal. The electronic chain includes a separating module configured to obtain, from the right input signal and the left input signal (LIN), at least four mono audio components, and a sound spatialization module configured to apply, to each mono audio component delivered by the separating module, a binaural filter previously selected from the plurality of binaural filters, and dedicated to the audio component, producing a sound whose source position is associated with the previously selected binaural filter.

摘要： A device for reducing crosstalk in an audio system that has first and second pairs of loudspeakers and first and second audio sources. The device is connected to each audio source and to at least the first pair of loudspeakers. The device includes a module for acquiring first audio signals from the first source and second audio signals from the second source, a module for determining crosstalk reduction filters resulting from a loudspeaker of the second pair, a module for calculating corrective signals, by applying the reduction filters to the second audio signals, and a module for generating corrected audio signals for the first pair, obtained from the first audio signals and corrective signals. Each reduction filter is obtained from transfer functions, each representing an acoustic path between a loudspeaker and a user's ear.
