Emission / reception of satellite-broadcast hyperfrequency signals with an interactive return path, using a protocol with spectrum measurement.

摘要

Patent Emission: "Transmitting / Receiving Interactivated Return Path Satellite Broadcast Hyperfrequency Signals Using a Spectrum Measurement Protocol". The present invention relates to a transmission / receiving facility (1) of radio frequency signals containing a transmission / receiving unit (2) comprising means (4) capable of receiving electrical signals from the transformation of radio signals received by terrestrial or satellite, these one-way electrical signals, a demodulator (21) capable of demodulating electrical signals according to a first modulation / demodulation protocol, a electrical signal modulator (5) according to a second modulation / demodulation protocol Unlike this first protocol, this second protocol being a protocol with spectrum measurement, this modulator (5) modulating the demodulated signals by this demodulator (21) and means (23) to transform these modulated electrical signals, according to the spectrum in radio signals capable of being transmitted by satellite. This installation also comprises one or more enclosures (11), including a modulator (14) capable of modulating electrical signals according to this first modulation / demodulation protocol and a coaxial cable (10) connecting the sending / receiving unit and enclosures.
