Abstract: 본 발명은 CELP 음성 부호화기를 이용한 패킷교환망이나 공중교환망을 통한 멀티미디어 서비스에서 패킷 손실 발생시 수신단에서 손실 패킷을 복구하는 방법에 관한 것이다. 손실 패킷 복구를 위해 선형예측 계수와 잔여 신호를 각각 보간하며, 미래 패킷을 사용할 수 없는 경우와 사용할 수 있는 경우로 구분하여 보간한다. 미래 패킷이 손실이면, 과거 데이터만을 가지고 복구하고, 미래 패킷이 정상적으로 수신되면 미래 데이터와 과거 데이터를 이용하여 손실 패킷을 보간한다. CELP 부호화기의 선형 예측 계수와 잔여 신호를 각각 보간한 뒤 합성하여 손실 프레임의 오디오 데이터를 복구 한다. CELP 부호화기의 비트스트림 정보를 이용하므로 많은 연산과정이 필요하지 않으며, CELP 부호화기에 보다 적합하게 구현할 수 있다. 또한, 손실 패킷 전과 후 프레임을 이용하므로 보다 정확하게 복구할 수 있으며, 선형예측 계수를 보간함으로써 연속손실 발생시 음질을 향상시킬 수 있다.

Abstract: PURPOSE: A low-delay formant FEC(Forward Error Correction) method is provided to use formant components of a future frame as surplus information used for restoring voice packet loss, thereby reducing delay and improving sound quality. CONSTITUTION: An input voice frame is compressed after a frame delay and a look-ahead delay, and a voice packet is generated after a compressive processing delay(310). A formant preparing for loss of the input voice frame is extracted(312). Packets are transmitted after the compressive delay(314). When the packets are transmitted from a transmission terminal, the packets arrive at a receiving terminal after a transmission delay(316). A certain packet is lost among the receiving packets inputted to a CODEC of the receiving terminal(318). When the packet is lost, the lost packet is restored by using surplus information(320).

Abstract: PURPOSE: An FFT(Fast Fourier Transform) scrambling and descrambling method is provided to firstly scale an amplitude of an FFT signal in a transmitter, and to scramble a position of a frequency component, in order to modulate an amplitude of the frequency component, thereby reducing residual intelligibility for an original signal. CONSTITUTION: A scrambling process(20) is performed as follows. An analog signal(201) is sampled to a sampling frequency, and is converted into a digital signal(202). An FFT processor binds digitally converted data in certain blocks, performs an N-point FFT process, and converts the data into a frequency region signal(203). A scaling table(220) is multiplied by a frequency component, and an amplitude scaling operation(204) is carried out to generate an amplitude-modulated signal. A position component of the frequency region signal is replaced(205), and an N-point inverse FFT process is performed(206). The signal becomes a real number sequence signal, and is converted into the analog signal(207), then is transmitted(208).

Abstract: PURPOSE: A tamper resistance device and a method for operating the same are provided to prevent data stored in a memory of an electronic device from being flowed out by an attack from an exterior or an illegal treatment. CONSTITUTION: An electronic device has a processor(114) which stores data in a memory(115) or reads/processes stored data. The electronic device is covered by an instrument(101). A luminous element(103) for emitting a light to an internal surface is included in the instrument(101). A light(109) emitted from the luminous element(103) is contacted with an internal surface(102) of the instrument(101) and the electronic device and dispersed to two-dimensional space or three-dimensional space. A partial portion of the dispersed light is collected in a light receiving element(111). An amount of a light collected to the light receiving element(111) is measured by a measuring device(112) and compared with a critical value in a comparator(113). In the case that the measured light amount is beyond tolerance, the comparator(113) outputs a predetermined signal to the processor(114). The processor(114) deletes data stored in the memory(115) in accordance with a signal from the comparator(113). The luminous element(103) is operated by a voltage being applied from an external power(107) or an internal power(106). If a level of the voltage become low or the power is stopped, a voltage comparison circuit(108) senses the variation and supplies a power from the internal power(106). A variable resistor(104) applies a power being supplied from the external power(107) or the internal power(106) to the luminous element(103) fixedly. The variable resistor(104) is controlled by a signal generated from a variable generator(105).
