Patent ID: 7784075

Claim:
System for the distribution of television (TV) type video signals with a frequency band of up to about 5 to 900 MHz, the said system comprising: an input coaxial cable ( 41 ) adapted for connection to a TV antenna ( 4 ) or to a cable television network, an output coaxial cable ( 53 ) adapted for connection to a television set ( 5 ), characterised in that it also comprises: a first input processing unit ( 1 ) comprising a coaxial input terminal ( 10 ), at least one low current terminal ( 11 ) for twisted wire pairs and processing means ( 14 ) for processing TV signals output from the input coaxial cable so as to transform them into signals with substantially the same transmission characteristics on the same frequency band on a twisted wires pair, at least one second output processing unit ( 3 ) comprising a low current input port ( 33 ) for twisted wire pairs, a coaxial output terminal ( 31 ) and processing means ( 34 ) for processing signals output from a twisted wires pair ( 12 ) connected to the first input processing unit ( 1 ) so as to transform them into signals substantially identical to the signals output from the said input coaxial cable ( 41 ), and at least one connecting cable ( 12 , 23 ) consisting of twisted wire pairs connecting the first processing unit ( 1 ) to the second processing unit ( 3 ), wherein the first input processing unit ( 1 ) comprises means of cutting off ( 16 ) the signal transmission in the case in which a coaxial cable ( 53 ) is not connected to the coaxial output terminal ( 31 ) of the second output processing unit ( 3 ).
