摘要： An error concealment method and apparatus that are adaptive to characteristics of blocks adjacent to a lost block, the adaptive error concealment method including: determining one or more thresholds for selecting an error concealment method, from a plurality of error concealment methods, based on one or more of characteristics of blocks adjacent to a current block having an error; generating a temporal activity and a spatial activity of pixels adjacent to the current block; and selecting an error concealment method, from the plurality of error concealment methods, for the current block according to a result obtained by comparing the temporal activity, the one or more thresholds, and the spatial activity.

摘要： 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.

摘要： 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. Also, when the search system is introduced into a network system, a separate linking software is not required.
