Abstract: An apparatus and method for compensating for data distortion caused by the phase slew of a frame reference signal in a User Equipment (UE) that accesses an asynchronous Wideband Code Division Multiple Access (WCDMA) communication system are provided. In the distortion compensating apparatus, an Finite Impulse Response (FIR) filter receives I channel data and Q channel data, each of the I and Q channel data having a plurality of chips, multiplies the I/Q channel data by a predetermined filtering coefficient, and outputs the product, in synchronization with the frame reference signal. A phase compensator compensates for an I-Q channel exchange occurring at an output end of the FIR filter when the phase of the frame reference signal is advanced or retarded.

Abstract: In the method for managing a variable bit rate so as to provide a streaming service and in the record medium capable of being read through a computer having a record of a program to realize the inventive method, a frame rate controlling system through a removal of a frame and a fidelity controlling system are used to change a bit rate of multimedia video data and thereby provide a multimedia streaming service based on the various bit rates according to a bandwidth change of a communication network, the fidelity controlling system being gotten by differently providing selection ranges for discrete cosine transform (DCT) coefficients in a unit of a block within a frame.

Abstract: In a cooperative computer based system for editing a web document including a plurality of clients a server, the cooperative computer based system includes means for generating editing instructions, converting editing instructions to a message related to editing and transmitting the message related to editing to the server; means for determining if the web document can be modified, based on the message related to editing; modifying contents of a copied web document stored in the server in conform to the message related to editing; and transmitting the message related to editing to the plurality of the clients; and means for modifying contents of the copied web document stored in each of the plurality of the clients in conform to the message related to editing transmitted from the server.

Abstract: In a method for performing a multipoint video conference in a video conferencing system and a computer-readable record media storing a plurality of instructions for performing the method, the floor is given to participants of a conference so that the multipoint video conference can be progressed without a necessity of an MCU, and audio/video streams of the participants who actually utter in the conference can be selectively transmitted according to a capability of a transmission system.

Abstract: There are provided a collaborative browsing method for allowing multiple users to see a web text simultaneously through transformation of URL and a recording medium for recording a program for realizing the method, which is able to be read by a computer. The collaborative browsing method applied to a collaborative browsing system, comprises: a first step of searching for a web page that a user requests, transforming the URL of the searched web page, storing it, and then transmitting the web page to the user; and a second step of sending the transformed URL of the web page to other users who participate in the same session in which the user is joining, and transmitting the stored web page to the other users if they request it.

Abstract: A multiaccess circuit for a memory, which arbitrates a multiaccess operation and suspends a pipeline operation until requested data is generated in the memory when the multiaccess operation to the memory is occurred in a certain step of the pipeline, is capable of effectively performing the pipeline operation, and the multiaccess circuit for the memory carries out the multiaccess operation to the memory in accordance with its priority, thus the pipeline operation is performed without any collision.
