Ah ok, From what I read and understand so far is that this cable is to connect home theater systems and it includes an Ethernet connectivity which means you surround sound big screen HD Smart TV can connect directly to your PC for Audio, Visual and Internet with one cable.
The average price for such cables is hovering around $800.
There are a few of them around.
There is also one that connects Iphones to USB but has the same features, Audio, Visual and Ethernet connectivity like a HDMI and Ethernet cable combined but for Iphone to connect to your PC or TV.
So you can plug your phone into your home theater and watch youtube and browse web directly from your Phone connection.
Ok the Dielectric Bias system attached to them is basically a charged cable that runs the length of the cable which produces a field that somehow helps the signal. Not too sure about it saying it aligns the electrons in the insulating wire. something like that..
The cheapest I found was around $700 for this cable.
Personally I would buy an Ethernet cable, A HDMI Cable and and New HD TV which I dont have for $700.
