A signal processing apparatus, performing modular multiplication in an electronic device, includes a first logic for outputting a signed multiplicand by selectively performing a one's complementary operation on a multiplicand according to a Booth conversion result of a multiplier in modular multiplication; a second logic for outputting a modulus which is signed in the modular multiplication based on a carry input value Carry-in of a current clock, determined from a carry value cin for correction of a previous clock, and on a sign bit of the multiplicand; and a third logic for receiving the signed multiplicand and the signed modulus, and calculating a result value of the modular multiplication by iteratively performing a full addition operation on a carry value C and a sum value S of the full addition operation, found at the previous clock.

Abstract: An information storage medium including graphic data and presentation information, and an apparatus and method of processing the graphic data are provided. The information storage medium includes the graphic data, page composition information which defines page composition of the graphic data, and the presentation information indicating when graphic screen data, which is composed with reference to the page composition information of the graphic data, is output to a display screen. Therefore, a graphic object is reusable in graphic data processing, and accordingly, a time taken to process the graphic data is reducible and memory area may be saved.

Abstract: Disclosed is a data transmission system that transmits data using a relay. During a first time slot, a base station may transmit base station data to the relay, and a mobile station may transmit mobile station data to the relay. During a second time slot, the relay may transmit the mobile station data to the base station, and transmit the base station data to the mobile station.

Abstract: An apparatus and a method for controlling a wiper position are provided. The apparatus to control a wiper position includes a controller to receive a wiper operation control signal output from a user input unit to control a wiper to be stopped at a desired position, a wiper motor to drive the wiper, a wiper relay switched to drive the wiper motor under a control of the controller, and a wipe sensor to sense a position of the wiper motor to transfer a position signal to the controller.

Abstract: An information storage medium storing subtitle text-based information, and a method and apparatus utilizing same, process a subtitle The information storage medium includes: dialog information which contains script text information of the subtitle and information specifying an output type of the script text; and presentation information which contains style information used to convert the script text into a bitmap format through rendering. With this structure, the amount of data required for a subtitle and the amount of data that should be processed when a subtitle is output may be greatly reduced.

Abstract: A graphics processing method and apparatus described herein is capable of converting graphics processing of a window system into a vector-based application program interface (API) format usable in the GPU and performing the converted graphics processing in the GPU. For example, the vector-based API may be based on an OpenVG standard or an EGL standard.

Abstract: A video encoding apparatus and method to distribute one or more macroblocks, classified into the same slice group, over an entire frame, according to the H.264 standard.

Abstract: A media access control (MAC) apparatus and corresponding methods for guaranteeing quality-of-service in a wireless local area network (LAN) are presented. The MAC method includes the steps of extracting, performing, determining, a first transmitting step, and a second transmitting step. The extracting step includes extracting a user priority from a frame received from an upper layer and separately storing a voice frame and a non-voice frame according to an access category (AC). The performing step includes independently performing backoff operations for the voice frame and the non-voice frame. The determining step includes determining whether the backoff operations for the voice frame and the non-voice frame have simultaneously ended. The first transmitting step includes transmitting the voice frame having a higher priority first and performing the backoff operation for the non-voice frame if the backoff operations have simultaneously ended.

Abstract: In a system for sharing hybrid resources in an independent network, each one of a plurality of stations preferably employs a sharing authority transferring protocol that allows the network control function to be moved from station to station depending on the network traffic. Although a distributed coordination method is normally used in the network, when an individual station determines that a real-time data stream is intended for the station, an apparatus having a method and data format for the use thereof allows control to be transferred to the targeted station. This allows the targeted station to control the sharing of the wireless hybrid resources using a centralized control method in a direct mode for the duration of the real-time service transmission, thereby optimizing network efficiency. As a result of using the distributed control authority of the present invention, a station may be freely subscribe/withdraw to/from the network.
