<p>The invention concerns a multimedia system for distributing high frequency signals in a cabled network in twisted pairs. Said system comprises: first impedance adapting means for receiving through a coaxial cable a high frequency signal (HF) and transmitting over a twisted pair of category 5, 6 or 7 said HF signal; second impedance adapting means for receiving the HF signal coming from the twisted pair of category 5, 6 or 7 and transmitting the HF signal to a specific terminal through a coaxial cable. The first impedance adapting means is a passive balanced converter. The second impedance adapting means is a passive unbalanced converter with HF signal amplification and automatic gain control.</p> |
