摘要： A set-top box, integrating a speaker having an acoustic box. At least two first loudspeakers and one second loudspeaker are integrated. The two first loudspeakers are positioned at the front and on each side of the acoustic box. A central axis (X2) of a membrane of the second loudspeaker is a vertical axis. The set-top box includes, in addition, a main electronic board having a decoding module and an audio module. The second loudspeaker and the main electronic board are positioned on either side and extending successively along a length (L′) of the set-top box which is perpendicular to a front-to-rear axis of the acoustic box.

摘要： A method including a device of an installation performing steps to determine whether an audio stream is played back in the installation by only one piece of audio playback equipment or by a group of at least two pieces of audio playback equipment (11a, 11b); if the device detects that the audio stream is played back by a single piece of audio playback equipment, then the device generates an order for said piece of equipment to apply a given set of equalization parameters; and if the device detects that the audio stream is played back by a group of at least two pieces of audio playback equipment, then the device determines the equalization parameters to be applied by each piece of audio playback equipment of said group, and generates a respective order for each piece of audio playback equipment of said group to apply a respective given set of equalization parameters.

摘要： 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.

摘要： Methods/devices for managing messages broadcast in a local area network (LAN) include nodes allowing an extension of wireless communication coverage and stations. The nodes are connected together by a backhaul subnetwork, and at least one node sends at least one wireless network to which the stations are connected. The LAN includes a primary subnetwork and a secondary subnetwork. The primary subnetwork is a subnetwork to which the links of the backhaul network and the nodes belong. The secondary subnetwork is composed of at least one station and is isolated from the rest of the LAN by a virtual network. A node able to apply the filtering rules demands an analysis of the topology of the local network, determines, from the topology of the LAN, filtering rules to be applied, and applies the filtering rules determined to the broadcast packets including at least one item of information identifying the virtual network.

摘要： A method of managing an audio stream that is read by audio playback equipment in a manner that is synchronized on a reference clock is provided. The method includes the following steps implemented in said piece of audio playback equipment: receiving the audio stream, the audio stream being in the form of packets, each packet comprising a succession of audio samples associated with identification information characteristic of a timestamp of said packet; playing the audio samples contained in each packet and storing a time given by the reference clock that is characteristic of the moment at which a predetermined sample of at least one of the packets is played; and sending a message including correspondence information concerning the correspondence between the identification information characteristic of a timestamp of said packet and the time stored in the preceding step.

摘要： A method for managing by management equipment including a first access point of a first network and a second access point of a second network, the first network having functionalities superior to the second network, each access point sending beacons, a station being able to process the beacons sent by the first and second access points or being able to process only the beacons sent by the second access point, the second access point performs the steps of: receiving an association request coming from a station, checking whether the station is able to process the beacon sent by the first access point, rejecting the association request if the station is able to process the beacons sent by the first access point, and associating the station if the station is not able to process the beacons sent by the first access point.
