摘要:
Apparatus and methods for establishing half-duplex communication between a first unit and a second unit over a telephone line. The first unit may transmit a first matching signal stream, the first matching signal stream including a first conditioning segment and a first unmodulated carrier signal having a first characteristic carrier frequency, the first characteristic carrier frequency representing a given transmission mode, the given transmission mode being in half-duplex. The second unit may analyze the first characteristic carrier frequency to recognize the given transmission mode.
摘要:
The invention relates to a control unit for an electrical generation/consumption system including generation sources (200) and consumption units (300) connected by a distribution network (100), including a control center (400) which transmits, to controllable consumption units (310) and to controllable generation sources (210), modulation orders based on warning information received from an external operator (500), on information relating to the potential of the respective suppression of units (310), and on information relating to the respective potential of generation or of a decrease in generation of sources (210), or of the suppression of the latter, at each unit (310), a module (312) which transmits, to the center (400), data updated in real time representing the potential modulation suppression of the unit (310), and at the sources (210), a module (212) which transmits, to the control center (400), data which is updated in real time and which is representative of the potential of generation or of the decrease in the generation of the source (210), or of the suppression of the latter.

摘要:
A method is provided for controlling, via a mobile terminal, a multimedia device for playing back and/or storing multimedia contents, the mobile terminal and the multimedia device being connected to a communications network. The method includes the following steps: the mobile terminal sends to a remote server, via the communications network, at least one request for activating a functionality on the multimedia device; the remote server translates this at least one request made by the mobile terminal into at least one query and transmits this at least one query to the multimedia device via the communications network, and; the multimedia device receives and executes this at least one query.
摘要:
A system for supplying digital multimedia documents via a telecommunications network. The system includes document server means (10) adapted to stream digital multimedia documents to user terminals (30) connected to the network (20) and each comprising a playback interface (32) adapted to play digital multimedia documents in real time. The document server means (10) include a multimedia content server (11) containing digital multimedia documents each associated with a playback index having values that identify predetermined portions of the document, index determination means (12) for determining at a given time during transmission of any document from the content server to a user terminal the current playback index value corresponding to the portion of the document being transmitted at that time, and transmission initiating means (12) for initiating transmission of any document from the content server to a user terminal starting from a portion of said document identified by a playback index value determined beforehand by said index determination means.
