Abstract: A method and apparatus for video enhancement by selectively reorganizing a group of pictures (GOP). The method includes counting the number of error blocks of a current frame to be decoded from among a plurality of frames included in the GOP; determining whether to display the current frame and one or more subsequent frames in accordance with the number of error blocks; and reorganizing a GOP with frames determined to be displayed and displaying the reorganized GOP.

Abstract: Photosensitive paste compositions, barrier ribs of plasma display panels (PDPs) prepared using the same, and PDPs including the barrier ribs are provided. The photosensitive paste composition includes an organic-inorganic complex sol and an inorganic material, wherein the average refractive index (N1) of the organic-inorganic complex sol and the average refractive index (N2) of the inorganic material satisfy the equation ?0.2?N1?N2?0.2. Using the photosensitive paste composition, patterned barrier ribs for PDPs having high resolution and high precision can be made by exposure to light only once. Barrier ribs having higher reflective indices than conventional barrier ribs can also be obtained.

Abstract: An error handling apparatus and method, and a computer-readable medium storing a computer program for executing the error handling method are provided. According to the method, in a case where a number of errors in object IP packets that are consecutively detected, each within a first predetermined time since a previous error detection, exceeds a maximum allowable number of errors, communication with a sending node of the erroneous IP packets during a second predetermined time is discontinued. Also, errors can be handled with reference to a cache unit including more than one entry identified by an address of a corresponding erroneous IP packet. Therefore, a network load of a receiving node can be reduced by not transmitting an internet control message protocol (ICMP) packet to a sending node where indiscriminate IP packet manipulations or denial of service (DoS) attacks are suspected during the second predetermined time.

Abstract: Disclosed relates to a structure of two-level n-gram inverted index and methods of building the same, processing queries and deriving the index that reduce the size of n-gram inverted index and improves the query performance by eliminating the redundancy of the position information that exists in the n-gram inverted index. The inverted index of the present invention comprises a back-end inverted index using subsequences extracted from documents as a term and a front-end inverted index using n-grams extracted from the subsequences as a term. The back-end inverted index uses the subsequences of a specific length extracted from the documents to be overlapped with each other by n?1 (n: the length of n-gram) as a term and stores position information of the subsequences occurring in the documents in a posting list for the respective subsequences.

Abstract: A remote control apparatus, method, and medium for enabling a server to control a plurality of clients located in remote areas is provided. The method includes: switching an environment of a server by loading display information stored in one of a plurality of backup buffers in a display processing module of the server; and transmitting the display information to one of the plurality of clients if there is a request for the display information issued by the one of the plurality of clients. Accordingly, it is possible to enable the plurality of clients to be simultaneously served by the server, regardless of which types of remote control protocols and which types of OSs the plurality of clients use, by repeatedly performing interrupt service routines for backing up display information of the plurality of clients to the respective backup buffers or loading the display information of the plurality of clients into the server.

Abstract: A method of and apparatus for securing a Mobile lpv6 packet. The method includes: confirming, by a mobile node in an external link, whether an address of the mobile node is registered at a home agent at which a home link of the mobile node is present; and discarding a packet that should be transmitted when it is confirmed that the address is registered.

Abstract: An apparatus and method for generating a checksum. The checksum generation method includes: determining whether or not an already calculated first checksum value is identical or similar to a second checksum value for which calculation is requested; if it is determined that the values are identical or similar, reading a difference value of the first checksum value and the second checksum value from a database; and by adding the read difference value to the first checksum value, generating the second checksum value.

Abstract: An Internet control message protocol packet generating system includes a field error detecting unit, which detects at least one field error upon reviewing all fields of the Internet protocol packet; and an Internet control message protocol packet generating unit, which records information for the at least one detected field error on the Internet control message protocol packet. The Internet control message protocol packet generating system may further include a field error information storing unit, which sequentially stores information on field errors detected by the field error detecting unit. The Internet control message protocol packet generating unit may generate the Internet control message protocol packet based on field error information stored in the field error information storing unit.

Abstract: An IPv6 header receiving apparatus and an IPv6 header processing method includes a register with a data size that is a multiple of an octet and modules for an IPv6 basic header or various types of IPv6 extended headers. The register receives IPv6 header data in units of an octet, stores the IPv6 header data, and transmits the stored IPv6 header data to an IPv6 processing module for that corresponds to the IPv6 header data. The modules receive the IPv6 header data from the register and process the IPv6 header data. Accordingly, IPv6 header data can be processed in real-time without wasting memory.

Abstract: A method for automatically linking index data with image data is disclosed. A first recording medium has both an index data base and first link data recorded thereon, and a second recording medium has both an image data base and second link data recorded thereon. The separate first link data which is not related to a search item, is added to each of record units of the index data base. The second link data is a label or a key chord which is connectively operated with the first link data. Accordingly, in the search system, the index list which is obtained by the search operation, is linked at a high rate with the image data which is recorded on the majority of recording media. Therefore, the minority of the first recording media having the index data base recorded thereon is linked automatically by the first and second link data with the majority of the second recording media having the image data base or a different form of data base recorded thereon so that the search operation is performed at a high rate.
