Patent ID: 8220015

Claim:
An addressing device for transmitting satellite TV signal and being electrically connected with a satellite down-converter and at least one STB installed at a satellite TV subscriber, the addressing device comprising: a GPS processing zone having a GPS chip, the GPS chip having a power terminal set and a first transmission terminal set, the power terminal set being adapted for receiving a DC operation voltage required by the GPS chip, whereby the GPS chip is operative for addressing the position where the addressing device installed and then carrying out digital security processing to output an address data via the first transmission terminal set; a control circuit zone having a transmission control chip and a power regulator, the transmission control chip having a second transmission terminal set electrically connected with the first transmission terminal set of the GPS chip and an integrated transmission terminal set adapted for receiving a DC operation voltage required by the transmission control chip, whereby the transmission control chip can convert the address data outputted by the GPS chip into an address signal having the same transmission frequency as that of the aforesaid satellite TV signal and then the address signal is outputted via the integrated transmission terminal set, the power regulator being electrically connected with the power terminal set of the GPS chip and the integrated terminal set for converting the DC operation voltage of the transmission control chip into that of the GPS chip; and a baseband transmission zone having two connection terminal sets electrically connected with the satellite down-converter and the STB respectively, the two connection terminal sets being electrically connected to the integrated transmission terminal set with the same transmission characteristics.
