Patent ID: 8634026

Claim:
A digital broadcast receiving apparatus configured to receive terrestrial digital television broadcasting and satellite digital broadcasting, comprising: a terrestrial digital tuner configured to receive terrestrial digital television broadcasting; a satellite digital tuner configured to receive satellite digital broadcasting; a demodulating block configured to demodulate a reception signal of said terrestrial digital television broadcasting with an output supplied from said terrestrial digital tuner, and, at the same time, demodulate a reception signal of said satellite digital broadcasting with an output supplied from said satellite digital tuner, said demodulating block including a first terminal connected to said terrestrial digital tuner establishing at least communication from said demodulating block to said terrestrial digital tuner and a second terminal connected to said satellite digital tuner establishing at least communication from said demodulating block to said satellite digital tuner; a terrestrial digital tuner control block, included in said demodulating block, configured to control said terrestrial digital tuner via a control signal supplied from said terrestrial digital tuner control block and applied to one of said first or second terminals of said demodulating block; a satellite digital tuner control block, included in said demodulating block, configured to control said satellite digital tuner via a control signal supplied from said satellite digital tuner control block and applied to a remaining one of said first or second terminals of said demodulating block; a switching block configured to switch application of, inside said demodulating block, said control signal supplied from said terrestrial digital tuner control block and said control signal supplied from said satellite digital tuner control block between said first and second terminals of said demodulating block in accordance with a positional arrangement of said terrestrial digital tuner and said satellite digital tuner relative to said demodulating block; and an additional switching block, wherein said demodulating block further includes a third terminal connected to said terrestrial digital tuner establishing at least communication from said demodulating block to said terrestrial digital tuner and a fourth terminal connected to said satellite digital tuner establishing at least communication from said demodulating block to said satellite digital tuner, and said additional switching block is configured to switch application of, inside said demodulating block, a second control signal supplied from said terrestrial digital tuner control block and a second control signal supplied from said satellite digital tuner control block between said third and fourth terminals of said demodulating block in accordance with said positional arrangement of said terrestrial digital tuner and said satellite digital tuner relative to said demodulating block.
