According to the present invention, a power transmission apparatus for a compressor comprises: an outer hub which is connected to a pulley, and which has a central hole formed therethrough; an inner hub spaced apart from the central hole of the outer hub and connected to a driving shaft of the compressor; and a limiter which interconnects the outer hub and the inner hub, and which has a fracture part. When axial force is applied to the limiter in the lengthwise direction of the driving shaft and a torque exceeds a preset level with the operation of the compressor disabled, the fracture part is destructed to cut off the transmission of power. The power transmission apparatus of the present invention is advantageous in that a load is applied to the limiter in the direction of the driving shaft, and thus the fatigue strength of the power transmission apparatus of the present invention is superior to those of conventional structures in that a fatigue load is applied to limiters in the rotating direction of the driving shaft by means of a frequent variation of torque, and shearing force caused by rotation is mainly applied.

The present invention is related to a method for processing signals of a super-resolution optical medium and an apparatus using the method. In one embodiment of the present invention, at the time of processing reproduced signals of a super-resolution optical disc, in addition to a general equalizer, a first limit equalizer that carries out selective amplification by using a frequency that corresponds to diffraction limit as a limit frequency and a second limit equalizer that carries out selective amplification by using a frequency that corresponds to the minimum mask as a limit frequency can be used. The present invention, therefore, effectively amplifies playback signals corresponding to short length marks/spaces and reduces distortion of reproduced signals and interference between symbols, thereby significantly improving reliability for data reproduction of a super-resolution optical disc.

Provided are an IPTV broadcast system and a channel setting method using a multi-channel streaming server. The system includes a set-top box (STB), a program guide database (DB), a transmission block storing unit, a customer management server, and the multi-channel streaming server. The STB performs a connection setting procedure for generating predetermined transmission control protocol (TCP) connection with the multi-channel streaming server when a user selects a channel and initially accesses an IPTV broadcast server system, and then requesting contents corresponding to information of the selected channel to reproduce received streaming data while buffering the same in a storage. The program guide DB stores transmission block information to be transmitted according to a time for each channel. The transmission block storing unit stores a transmission block of respective contents. The customer management server stores customer information and authentication information and processes authentication when authentication is requested. The multi-channel streaming server communicates with the customer management server to authenticate a user according to a predetermined authentication procedure when connection setting is requested by the STB, sets connection when the authentication is successful, searches for the program guide database according to the channel information to find out information regarding a transmission block corresponding to a channel number and a time band requested by the STB, fetches the transmission block from the transmission block storing unit, and transmits the transmission block to the STB.

The present invention relates to a method for actuating a vibration motor, and more particularly, to a method for saving various formats of vibration pattern data of a vibration motor by using only an initial vibration frequency, change in vibration frequency, and the total number of vibrations. The method for saving a vibration pattern data, according to the present invention, can express various vibration patterns with a small amount of data by expressing various vibration patterns of a resonance-free frequency vibration motor in terms of the initial vibration frequency, the size of change in the vibration frequency, and the total number of vibrations necessary for reaching the final vibration frequency. In addition, the method for saving vibration pattern data, according to the present invention, can allow manufacturing of a user terminal enabling a haptic function at low cost by expressing the vibration pattern of the resonance-free frequency vibration motor with little data and low data processing speed.
