Abstract: PURPOSE: A method of controlling a telephone system having jamming prevention and secret call functions is provided to transceive data instead of a voice calling by the secret call function, and to transceive data through encoder/decoder only between callers by an encoding algorithm for voice data, then to inform on a jamming and a wiretapping by checking an impedance and data errors, so as to maintain secret calls. CONSTITUTION: A CODEC(10) converts analog voice signals into digital signals or converts digital signals into analog voice signals. A micro controller(20) randomly modulates data through an encoding key transceived between callers, or demodulates the modulated data, and controls signals of a keypad(30) or a display device(40). The keypad(30) transmits signals to the micro controller(20) by pressing a telephone number of the other party. The display device(40) receives a signal for displaying a telephone number of a caller from the micro controller(20). A modem(50) transmits a modulated signal of the micro controller(20) to a DAA(Data Access Arrangement)(60), or receives a signal of the DAA(60) to transmit the signal to the micro controller(20). The DAA(60) transmits the signal received from the modem(50) to a PSTN.

Abstract: PURPOSE: A PC/TV unified remote controller system having multi-functional wireless telephone and wireless mouse functions is provided to perform multi-functional TV remote controller, wireless keyboard, wireless mouse functions using one remote controller and add a wireless telephone function to prove wireless telephone, wireless microphone and wireless Internet phone functions. CONSTITUTION: If a pushed key is a key for using a wireless telephone, an Internet phone, and a wireless microphone, the content is informed to a microcomputer of a wireless telephone handy unit(131) through a communication line(121). An infrared data process microcomputer(111) converts an electric signal varied from a wireless mouse position detecting circuit(112) into an infrared ray, generates a digital code, and transmits the digital code to an infrared data receiving device of a fixing device(200). An infrared data receiving microcomputer(211) analyzes a signal received from a transmission circuit(212) of an infrared data receiving unit(210) and judges whether the analyzed signal is keyboard and mouse data. If the analyzed signal is a keyboard control code, the keyboard data are transmitted to a keyboard port of an Internet TV/general computer(300) through an interface unit(213). If the analyzed signal is the mouse data, the mouse data are transmitted to a mouse port of the Internet TV/general computer(300) through a mouse interface unit(214).
