  • Patent number: 11924622
    Abstract: A processor device for processing an incoming audio stream, the device including: a configuration element arranged to acquire input parameters having both first characteristics of the incoming audio stream and also second characteristics of the audio playback devices, and to produce configuration parameters on the basis of the input parameters; a master element arranged to define processing sequences from the configuration parameters, each processing sequence being associated with and adapted to a respective playback channel, to apply the processing sequences to the incoming audio stream so as to produce processed audio streams, each adapted to a respective one of the playback channels, and to transmit to each piece of equipment including an audio playback device the processed audio stream is adapted to the playback channel associated with the audio playback device.

  • Patent number: 11910168
    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.

  • Patent number: 11756590
    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 (?t_a, ?t_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.

  • Publication number: 20220013131
    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.

  • Patent number: 10375435
    Abstract: A method for programming a recording of a program by a digital television decoder. The decoder has a service plan including a plurality of services. The program to be recorded is broadcast on a first service. The decoder is aware of the first service, an identifier of the program to be recorded, and a theoretical start time of the program to be recorded. When the decoder receives a first standardized table from the first service, the decoder is put in a first operational mode in which the decoder starts recording the program based on the detection of an identifier of the program in the first standardized table, and, when the decoder detects no reception of the first standardized table, the decoder is put in a second operational mode in which the decoder starts recording the program based on the theoretical start time of the program.

  • Publication number: 20180198834
    Abstract: Method for transmitting a data stream between a server and a client using the streaming protocol based on HTTP including the following steps implemented by the server following a reception of at least one item of information representing a capacity of said client: adapting an initial data stream to each capacity received in order to obtain an adapted data stream; decomposing the adapted data stream into segments; transmitting to the client an item of descriptive information making it possible to obtain, for each segment, a loading address of said segment, said descriptive information enabling the client to request from the server a transmission of the segments in order to obtain the adapted data stream.
