Abstract: An audio device includes a frequency component extraction module; a selection module arranged to select at least one selected audio channel and to control the extraction module so that it extracts the frequency components only from the at least one selected audio channel; a processing module arranged to carry out at least one processing operation that results in an interchannel delay on the at least one selected audio channel, from which the frequency components have been removed, and on the at least one non-selected audio channel; and an injection module arranged to add together said frequency components on each processed audio channel.

Abstract: Audio playback equipment includes a loudspeaker, a photosensitive sensor and a processing unit arranged to: acquire or estimate, by using at least one measurement produced by the photosensitive sensor, at least one light parameter representative of a light illuminating an environment of the audio playback equipment; select, according to the light parameter, current values of audio parameters; apply the current values of audio parameters on a primary audio signal (Sap) to produce a secondary audio signal (Sas); playback the secondary audio signal via the internal loudspeaker.

Abstract: A set-top box includes a setting module configured to carry out and/or control analyses in real time on at least two distinct data sources relating to the input stream, the data sources being selected among metadata associated with the input stream, a current audio signal coming from the input audio signal, and, if the input stream also comprises an input video signal, at least one target image coming from the input video signal, and define, on the basis of the results of these analyses, a genre of the input stream, the genre being associated with audio parameters; and a configuration module which dynamically adapts, using the audio parameters, a setting of an audio playback device incorporated into or connected to the set-top box and comprising at least one loudspeaker.

Abstract: A set-top box includes a setting module arranged to define a genre of the input stream, which is associated with audio parameters, a configuration module arranged to dynamically adapt, by using the audio parameters, an adjustment of an audio playback device, so as to optimise a sound rendering of said audio playback device according to the genre of the input stream, and a control module, arranged to detect an occurrence of a current event from among a set of predefined events relating to the broadcasting of the input stream, and to control the setting module according to said current event, so as to optimise a use of resources of the setting module and therefore of the set-top box.

Abstract: An accessory equipment includes a wireless communication circuit, and a routing circuit arrange to receive from a source equipment, via the input port and the first wired link, a digital audio-video signal including a video signal and audio channels, the audio channels including at least one first audio channel belonging to a multi-channel audio signal, and at least one second audio channel, transmit to the wireless communication circuit only the at least one first audio channel for the wireless communication circuit to transmit to at least one audio rendering equipment via a wireless link, and transmit to the audio-video rendering equipment only the video signal and the at least one second audio channel.

Abstract: Disclosed is video communication method implemented by a device comprising a processor and a memory comprising software code, the processor executing the software code causing the device to implement the method, the method comprising: obtaining an image generated by a camera; detecting one or more people in the image; in the event that one or more persons are detected, checking for each person a criterion indicating whether the person should or should not be part of the video communication; processing the image to erase from the image the detected person(s) who should not be part of the video communication; transmitting the processed image. Also disclosed are an implementation device, a storage medium, and a computer program product.

Abstract: A method and an audiovisual set-top box for recommending a list of at least one audiovisual programme to at least one user, the programme or programmes being categorised in genres and/or subgenres. The method has steps, performed by the audiovisual decoder, of: associating said genres and/or said subgenres with emotional states; detecting a current emotional state of said at least one user; performing a sorting of said programmes in said catalogue taking account at least of said emotional state detected and said genres and/or subgenres associated with said emotional state detected; and displaying a list of at least one audiovisual programme taking account of said sorting of said programmes in said catalogue. This makes it possible to take account of the detected current emotional state of the user in order to improve the relevance of the programmes that are recommended to them.

Abstract: A method of playing back audio/video signals by means of an audio/video system includes a decoder appliance connected to a display screen and to a wireless speaker including a buffer storing audio frames so as to allow latency between receiving encoded audio frames and supplying decoded audio frames. The method comprises the steps of: determining a filling level of the buffer; comparing the filling level of the buffer with a filling target for the buffer and deducing a filling difference therefrom; and increasing or decreasing the number of audio frames that are stored as a function of the filling difference so as to adjust latency.

Abstract: A optimization method for a sound playback performed by a set-top box including at least one speaker, and to which at least one camera is secured. The method include the steps of: acquiring an initial image produced by the camera while the set-top box is in an initial position and in an initial orientation, the set-top box thus using initial audio parameters to optimize the sound playback; then, acquiring at least one current image; analyzing the current image and the initial image to detect a change of position and/or orientation of the set-top box; performing at least one corrective action to optimize the sound playback.

Abstract: A method of grouping together pieces of equipment that are capable of emitting sound signals, the method comprising the steps of: causing each piece of equipment to emit a test sound signal; causing the test sound signal to be received by each piece of equipment that is capable of receiving sound signals, and causing each of these pieces of equipment to evaluate a recognition level for said test sound signal; or each pair of pieces of equipment Ei and Ej, evaluating a mutual recognition level representative both of a recognition level N(i, j) for the piece of equipment Ei receiving a test sound signal emitted by the piece of equipment Ej, and also of a recognition level N(j, i); on the basis of the mutual recognition level, determining whether or not the pieces of equipment Ei and Ej belong to a common sound space.
