Abstract: A method and a device for controlling the state of a device including means for transferring an audiovisual source and means for reproducing an audio signal, the device being connected to a television set by means of an HDMI connection in accordance with an HDMI specification version 2.0 or higher. The device is in an operating mode as an audiovisual source or for reproducing an audio signal coming from the HDMI connection. The device: receives a change command, goes into the mode of reproducing an audio signal coming from the HDMI connection if it is in the audiovisual source mode, checks whether an audio signal coming from the HDMI connection is present and, if so, reproduces the audio signal coming from the HDMI connection by the means for reproducing an audio signal.

Abstract: A method and a device for managing the operating mode of a device includes transferring an audiovisual source and reproducing an audio signal, the device being connected to a television set of an HDMI connection. A device: attributes to itself an audiovisual source logic address, sends a request for obtaining the version of the HDMI specification of the television set, operates in an adapted operating mode if the version of the HDMI specification implemented by the television set is lower than a version of the HDMI 2.0 specification, attributes to itself an audio system logic address, sends a request for obtaining the version of the HDMI specification of the television set, operates in an operating mode according to the HDMI specification version HDMI 2.0 if the television set has responded to each request, and operates in the adapted operating mode if the television set has not responded to each request.

Abstract: 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.

Abstract: A method of decoding an incoming audio/video stream received by a decoder box that is connected to audio playback equipment and to video playback equipment, the method comprising the steps of evaluating an audio latency and a video latency; if the audio (or respectively video) latency is greater than the video (or resp. audio) latency, testing a first condition to ensure that the time difference (Δt_a, Δt_v) between the presentation time stamp of the audio (or resp. video) samples and the reference clock signal is sufficient, and if the first condition is satisfied, acting, when decoding the audio (or resp. video), to decrease the presentation time stamp of the audio (or resp. video) samples in order to advance playback of the audio (or resp. video) samples, thereby compensating at least in part the latency difference between the audio (or resp. video) latency and the video (or resp. audio) latency.
