Abstract: 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.

Abstract: 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.

Abstract: 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.
