[CABLE SIGNAL DISTRIBUTION SYSTEM]
First Claim
1. A cable signal distribution system, in combination with an existing cable network in a building, cable device input in the building connected to the existing cable network to supply at least one cable device, cable signal input from outside the building connected to the existing cable network to provide an initial cable signal into the building and a CATV digital set top box, comprising:
- a turn-around splitter including an input and at least two outputs, said input connected to the cable signal input;
a first of at least two outputs of said turn-around splitter connected to the cable device input by a first coaxial cable;
a second of at least two outputs of said turn-around splitter connected to a second coaxial cable to provide a path between said turn-around splitter and the CATV digital set top box;
said turn-around splitter including band splitting electronics to divide the initial cable signal into a high frequency band and a low frequency band as the initial cable signal enters said input of said turn-around splitter;
said band splitting electronics having the capability to transmit said low frequency band out said at least two outputs of said turn-around splitter, said band splitting electronics having the capability to terminate said high frequency band of said initial cable signal entering said turn-around splitter and prevent transmission of said high frequency band of the initial cable signal entering said turn-around splitter to said at least two outputs of said turn-around splitter, said band splitting electronics having the capability to receive a frequency in a range of said high frequency band at said second of said at least two outputs of said turn-around splitter which is transmitted on said second coaxial cable towards said second of said at least two outputs of said turn-around splitter and redirect said frequency in a range of said high frequency band to said first of said at least two outputs of said turn-around splitter;
a reverse transmitting device connected between said second coaxial cable and the CATV digital set top box, said reverse transmitting device configured to receive the output cable signal from the CATV digital set top box, said reverse transmitting device configured to convert and transmit the output cable signal from the CATV digital set top box as a converted output cable signal on a frequency in a range of said high frequency band to said second of said at least two outputs of said turn-around splitter; and
said first of said at least two outputs connected to said second of said at least two outputs of said turn-around splitter such that said converted output cable signal from said reverse transmitting device transmitted on the range of said high frequency band to said second of said at least two outputs of said turn-around splitter on said second coaxial cable is transmitted to said first of said at least two outputs of said turn-around splitter and onto the cable device input by said first coaxial cable to feed said at least one cable device in the building with said converted output cable signal from the CATV digital set top box.

Abstract
A cable signal distribution system to allow the distribution of a digital cable signal in a building using the existing cable network in the building. The cable signal distribution system is a low cost system coupled with simple functionality. The cable signal distribution system splits the initial cable signal frequency range into two separate bands, a low band for operating cable television system-related equipment, and a higher frequency band used to create a Home Band Network of cable frequencies within the cable signal frequency range. The Home Band Network is used to transmit the channel tuned by the CATV digital set top box to existing analog Televisions in the building.

7. A method of distributing a digital cable signal in a building using the existing cable network in the building, comprising:
-
receiving an initial cable signal into a building and feeding the initial cable signal into an input of a turn-around splitter, splitting the initial cable signal into a high frequency band and a low frequency band at the turn-around splitter, whereby the turn-around splitter includes band splitting electronics to divide the initial cable signal into the high frequency band and the low frequency band as the initial cable signal enters the input of said turn-around splitter;
