Patent ID: 8310598

Claim:
An apparatus for splitting a signal, comprising: a first splitting unit to split an inputted broadcast signal into a first broadcast signal and a second broadcast signal, and to supply the first broadcast signal to a first broadcast signal processing element; a second splitting unit to split the second broadcast signal into a third broadcast signal and a fourth broadcast signal, and to supply the third broadcast signal to a second broadcast signal processing element; and a third splitting unit to split the fourth broadcast signal into a fifth broadcast signal and a sixth broadcast signal, and to supply the fifth broadcast signal to a third broadcast signal processing element and supply the sixth broadcast signal to a fourth broadcast signal processing element, an isolating element disposed between the second splitting unit and the third splitting unit to isolate between input ends of the first and the second broadcast signal processing elements and input ends of the third and the fourth broadcast signal processing elements, wherein the second splitting unit supplies the fourth broadcast signal to the third broadcast signal processing element and wherein the first broadcast signal processing element comprises a broadcast signal processing element to require a broadcast signal having a noise figure lower than that of the second and the third broadcast signal processing elements.
