  • Patent number: 6498866
    Abstract: According to the invention, the method of primary processing of a first set of primary data (IM,f) representing physical quantities includes: a set division step (200A to 202) during which the first set of data is divided into sub-sets of first data, and for each first sub-set of data: a step (205 to 207) of “constructing” a global contractive mapping of the first type, for the said first sub-set of data, whose fixed point constitutes an approximation of all or part of this sub-set. The set of parameters (ai, b) thus determined constitutes a primary representation of the said first set of data.

  • Publication number: 20020006175
    Abstract: The present invention concerns a method of transmitting blocks of data, in which, for at least one of said blocks of data, at least one parameter associated with this block of data is transmitted, said parameter representing the relative importance of the block of data associated with this parameter within the message transmitted by all the blocks of data, characterised in that the data are coded by means of a channel coding method which does not take into account said parameter. Correlatively, the invention also concerns a decoding method associated with this transmission method.

  • Patent number: 6333705
    Abstract: In order to code a digital signal, it is decomposed (20) into several subsignals; each subsignal is coded (38) by means of a coding technique taken from amongst M coding techniques Ci; and the stream of coded bits thus produced is entered (40) in a first part of a file intended to receive the coded digital signal. Then the application, successively to each coded subsignal, of each decoding technique Di associated with the coding technique Ci is simulated (48); and if and only if at least two different decoding techniques are acceptable, within the meaning of a predetermined likelihood criterion, for decoding the same coded subsignal, there is entered (52) in a second part of the file information making it possible to select, during decoding, the decoding technique associated with the coding technique used for coding this subsignal.

  • Patent number: 6266451
    Abstract: The method for primary processing according to the invention takes into account a minimum dimension and a partition of a set of data into so-called “initial elementary” subsets (Ki). It includes: a) for each elementary subset which size is larger than the minimum dimension, one iteration of: a division suitability estimation step, and when appropriate, a step of “supplementary partitioning” of the said subset, b) a “construction” step of a global multidimensional mapping and non-linear mapping, the restrictions of the global mapping to the elementary subsets (Ki) being composed of elementary mappings, the fixed point of the global mapping constituting an approximation of all or part of this set, the set of parameters (ai, b) determined by the restrictions constituting an approximation of the said set of data.

  • Patent number: 6215422
    Abstract: The invention proposes a digital signal coding method including a step of analysing (E1) the digital signal (IM) into a plurality of frequency sub-band signals distributed according to at least two different frequency bands, at least one first sub-band signal having a lower frequency and at least one second sub-band signal having a higher frequency, characterised in that it includes, for each second sub-band signal, the steps of: dividing (E4) the second sub-band signals into blocks (Bi,n), selecting (E9) blocks to be coded by setting to a predetermined value, according to a selection criterion, coding the blocks selected by setting to the predetermined value.

  • Patent number: 6122267
    Abstract: The methods for transmission of sequences or frames of data provide for retransmitting, with a central device (21), frames of data which reach it, to destination devices, by transmission of downlink frames when the destination device is a peripheral device (24), each downlink frame having systematically a service message activating a protocol controlling access to the transmission medium shared by the central device (21) and the peripheral devices (24), and possibly a frame of data. The central device (21) and at least one peripheral device (24) form a system which is particularly well suited to a local area network, notably with a wireless transmission medium.

  • Patent number: 5991275
    Abstract: A digital communication converter includes: a connection unit with a communication unit from which it receives or to which it delivers data frames; and a unit for sending/receiving over a transmission medium in order to transmit, by means of the medium, data frames which are delivered to it and/or to deliver information frames which it receives by means of the medium. A transmission control unit delivers, respectively to the connection unit and the sending/receiving unit, frames which have been delivered to it respectively by the sending/receiving unit and by means of the connection unit. A memory stores an address relating to the communication unit, this address being used for operating a protocol for controlling access to the transmission medium.
