Abstract: PURPOSE: A service management system for supplying a differential service on the Internet and a service method therefor are provided to supply a priority service to a user wanting to have more than basic service, and to enable the user to receive a differentiated service on the Internet, thereby supplying a commercialization model of the differentiated service. CONSTITUTION: A host and communication module(31) authenticates user information inputted from a host, and transmits an assigned service IP address to the host. A service assignment deciding module(32) guides service kinds to the host, and receives a response from the host. A DHCP server module(33) assigns one of IP addresses according to a decided service kind, transmits the address to the host, and records service usage time, the assigned IP address, and user identifier information of the host in a DB(34). A router and communication module(35) communicates with a router. If the assigned IP address is not assigned to receive a service, the DHCP server module(33) assigns a specific IP address to the router as a specific service.

Abstract: PURPOSE: An apparatus and a method for allocating resources according to path colors for a differentiated service is provided so that an ISP(Internet Service Provider) can provide a differentiated service to Internet users. CONSTITUTION: A bandwidth broker(300) comprises a user interface part(310), a determination part(320), a GUI part(330), a router interface part(340), a database(350), a routing protocol part(360), and an SNMP management part(370). The bandwidth broker(300) receives user requirements from a user terminal(380) through the user interface part(310), and delivers a resource allocation result to the user terminal(380) through the user interface part(310). The determination part(320) checks the user's contract observance items, based on the user requirements transferred from the user interface part(310), and determines whether the user's request is acceptable. In this case, the bandwidth broker(300) executes acceptance control, based on a path color. The database(350) stores user requirements, router setup conditions, network resource usage policy, router information, network configuration information, etc. The routing protocol part(360) collects network configuration information, stores it in the database(350), and uses stored information in setting up each path between edge routers. The SNMP management part(370) collects information from routers through an SNMP and stores it in the database(350).

Abstract: PURPOSE: An intra prediction encoding and decoding method and an intra prediction encoding and decoding apparatus implementing the method are provided to reduce overhead related to mode bit with the selection of a prediction mode through peripheral blocks. CONSTITUTION: A first intra prediction unit(111) respectively calculates the degree of pixel correlation by intra prediction direction between a macroblock and the peripheral blocks of the macroblock. A second intra prediction unit(113) performs the intra prediction of the macroblock with the mode information of the peripheral block in the upper part of the macro block. A third intra prediction unit(115) performs the intra prediction of the brightness component of a current picture. A mode selection unit(117) selects an optimal intra prediction mode.
