Abstract: The invention relates to a device and a method for recording data on a recording medium. The invention relates to the implementation of the timeshift function in a part of said recording medium called the timeshift buffer memory having a size defined in terms of recording capacity. For the timeshift buffer memory, a first threshold defines a capacity limit, a second threshold defines a recording time limit. The device records the data in the timeshift buffer memory as long as the second threshold is not reached and when the second threshold is reached before the first threshold, the processor truncates the start of the timeshift buffer memory when the data being read are not located at the start of the buffer memory or moves to reading the data of the timeshift buffer memory when the data being read are located at the start of the timeshift buffer memory.

Abstract: A method is provided for transmitting a digital signal via n transmit antennas, wherein n is strictly greater than 2. The method includes combining with a source data vector n vectors to be transmitted respectively by each of the transmit antennas by a coding matrix <I>M</I> with a yield equal to 1, using reference symbols known to at least one receiver whereby it is able to estimate at least three transmission channels corresponding respectively to each of the transmit antennas. The coding matrix <I>M</I> applies a mathematical transformation to the reference symbols prior to the transmission thereof.

Abstract: A cordless telephony device includes a base station for radio communication with a handset on an operating frequency selected from a set of frequencies. The base station and handset include a scanning element for receiving and analyzing a connection request transmitted on a transmit frequency between the base station and handset. The receiving one of the base station or handset detects the transmit frequency and selects the transmit frequency as the operating frequency for radio communication between the base station and handset.

Abstract: A cordless telephony device is disclosed which includes a base module and at least one handset module. Each of the modules includes a transmitting and a receiving circuit with scanning means for analyzing the various channels (N) in turns so as to examine whether a request for a connection has been emitted on a channel. A definition (L) of the channel used is indicated in the data of a request for a connection emitted by a transmitter. Each module includes means for searching for the channel number (L) in the received data during a scanning operation in the receive mode, and for immediately settling on the channel that carries this number (L) if this channel number L is different from that (N) of the analyzed channel.

Abstract: An wireless communication system has a master station and a slave station. The master and slave stations exchange identification signals and call signals, and include a cut-off unit for cutting off the call signals during reception of the identification signals. The cut-off unit of the master station generates a master cut-off signal after transmission of a master identification signal to the slave station. The slave station transmits to the master station a slave identification signal in response to reception of the master identification signal so that the master cut-off signal is aligned with the slave identification signal received by the master station. The cut-off unit of the slave station generates a slave cut-off signal for alignment with the reception of the master identification signal. The slave station includes a differential circuit and a correction circuit.
