Abstract: PURPOSE: A quality measuring apparatus of a VoIP(Voice of Internet Protocol) based voice terminal is provided to offer stable VoIP services and to extract an objective quality index by using wideband codec. CONSTITUTION: An MOS(Mean Opinion Score) processing unit(330) extracts MOS values of signals. A wideband voice codec compensator(340) creates a voice codec compensation coefficient. When the extracted MOS value is an environment where a terminal is connected, a result output unit(350) adds the voice codec compensation coefficient to the MOS value of the signal which uses the extracted wideband codec. The result output unit outputs the calculated value as the quality index of voice quality.

Abstract: A codec bit rate control method for guaranteeing QoS of voice in a wireless LAN VoIP system is provided to adjust the amount of voice data through a variable bit rate characteristic of G.729.1 in a channel deterioration situation of a wireless LAN, thereby guaranteeing QoS of voice. An AP(Access Point) collects channel state information to grasp channel occupation time of terminals connected to the AP(S230). Each terminal adjusts a codec bit rate based on a channel occupation rate of the terminals about total channel capacity(S255,S260). The adjusted codec bit rate is transmitted.

Abstract: An improved layer encoding/decoding method is provided allocate addition mantissa information to each sample in order to reduce quantization error of 711 codec. Characteristic indexes of addition mantissa information of each sample are calculated based on characteristic information of each sample of a frame(S510). A process of performing each bit allocation to samples including current characteristic index is repeatedly performed until total number of bits allocated to the samples is consistent with total number of bits available in the frame(S520). The current characteristic index is set to be smaller from the maximum value as much as one whenever repeatedly performing the above step(S530). Most significant bits corresponding to the number of bits allocated to each sample among bits of the addition mantissa information of each sample of the frame are outputted.

Abstract: A method and an apparatus for matching measurement interval of speech quality of variable band multi-codec are provided to match a measurement interval between a reference sound and a codec sound and reduce a measurement result distortion phenomenon. A measurement interval setting unit(110) sets an interval of speech quality desired to be measured by time intervals, and the first conversion unit(120) converts the measurement interval by sample units. An information synthesizing unit(130) synthesizes information about the measurement interval which has been converted by sample units and a digital original sound, and outputs the same.

Abstract: A method and an apparatus for direct memory access control are provided to minimize frequency of a process accessing an external memory for processing interrupt by minimizing frequency of interrupt in a direct memory access controller regardless of size of a storage medium of a voice output device, thereby improving performance of a system. If DMAC(Direct Memory Access Control) operation is requested, data to transmit is acquired and stored inside(S201-S203). The data is acquired as much as initial burst size to transmit the data to a storage medium for output(S204-S206). Size of burst is reset in accordance with a state of a data destination and the data is acquired as much as the reset burst size to transmit the data to the data destination(S208-S210). If all data are transmitted, interrupt is generated(S211). If not, it is judged whether a retransmission step is operated.
