摘要： Provided are a packet processing apparatus for realizing a wire-speed, and a method thereof. The packet processing apparatus realizes a wire-speed by making an inputted packet be processed in another packet processing apparatus instead of processing the inputted packet for itself. The packet processing apparatus for realizing a wire-speed by having an inputted packet processed in a packet processor of another packet processing apparatus by making an inputted packet detour a packet processor into a detour path, includes: a packet classifier for classifying and storing the inputted packet in a multi-queue based on a priority; a queue manager for including the multi-queue, determining a detour packet among packets stored in the multi-queue and marking the packet as a detour packet; and a packet scheduler for transmitting the packet designated as the detour packet to the detour path. The apparatus is used for a packet communication system.

摘要： Provided is an audio coding apparatus and method that can selectively apply a operation mode of a coding module for stereo or multi-channel representation according to input signal characteristics of each channel, when voice or music signals are transmitted using an audio codec in portable terminals capable of stereo or multi-channel input and output. The audio coding apparatus includes a down-mixer for down-mixing multi-channel audio signals into mono signals; a coder for coding the mono signals; an input channel correlation analyzer for deciding whether to give them stereo effect based on their signal distribution characteristics, and outputting a control signal indicating whether to perform stereo representation process; and a stereo representation unit for performing stereo representation process onto the multi-channel audio signals when the control signal indicating to perform stereo representation process.

摘要： A method for transferring data frame end-to-end in a local area network is provided. In the method, a virtual synch frame shaper is loaded on a frame transmission layer structure provided in end stations in transmitting and receiving sides, which transmits data frame passing through a plurality of Ethernet switches in the LAN. Then, slot counters, which are counted through the virtual synch frame shaper, are exchanged between the end stations, and the slot counters are synchronized. Afterward, the transmit time slot is allocated based on the synchronized slot counters for transmitting data frames between the end stations. Finally, data frames are transmitted based on the synchronized slot counters and the allocated transmit time slot.
