The method for RTPS discovery based on a DHT includes: registering, by a participant peer of participants, the participants in a distributed hash table (DHT) of an overlay network; obtaining location information on relative participants to be discovered from the DHT; sharing information on entities of the relative participants by exchanging a discovery message with the participant peer based on the location information on the obtained relative participants; and performing handshaking between the entities of the participants and the entities of the relative participants. Therefore, the exemplary embodiments of the present invention can rapidly and efficiently perform the discover of the participants based on the DHT.

Abstract: The present invention provides a lightweight multicast method and apparatus for a data distribution service. The lightweight multicast apparatus includes a network congestion detection unit for multicasting packets to a plurality of subscriber node terminals, and detecting a cause of network congestion using a negative response message transferred from a relevant subscriber node terminal that could not receive the packets among the plurality of subscriber node terminals. A network recovery control unit determines a recovery control policy depending on the cause of the congestion detected by the network congestion detection unit, and solves the cause of the congestion.

Abstract: Provided are a coded block pattern (CBP) estimating method which is performed using an average value and a dispersion value between blocks of CBPs in a moving picture encoder for IP-TVs (Internet Protocol-Televisions), and a block mode decision method, which can determine all block modes with only the first 16×16 block. Accordingly, since an additional operation for mode determination is not necessary, an amount of calculation and thus a calculation time can be remarkably reduced.

Abstract: A membrane-based electroosmotic pump, having catalyst regions on electrodes, can pump a fluid without applying an external voltage. Chemical reactions of fluid components on the catalyst regions on the electrodes can induce an electric field that generates an electroosmotic flow through channels of the membrane.

Abstract: The present invention relates to a half-pel motion estimation method. The calculation object half-pel, which is in the block of the previous or next reference frame, is not estimated additionally for each block of the current frame divided into blocks of a predetermined size. The present invention suggests an algorithm that can perform half-pel search only with a SAD value used in integer-pel search and a random variable for correcting errors. Since the present invention does not have to generate half-pel for motion estimation, the calculation amount is amazingly reduced and the calculation time is reduced.

Abstract: Disclosed is a remote input method using a fingerprint recognition sensor. A main device activates a fingerprint input mode according to a user's request, and displays a key input unit, menu images and an indicator corresponding to the fingerprint input mode. A remote input device having the fingerprint recognition sensor generates fingerprint data corresponding to the finger touching method in real time, and sends the generated fingerprint data to the main device through a short range wireless communication module. When receiving the fingerprint data, the main device analyzes the type of fingerprint included in the fingerprint data based on the previously stored fingerprint information. The main device also analyzes the user input pattern according to the type of fingerprint and the fingerprint data reception type. Consequently, the main device implements a preset function corresponding to the analyzed user input pattern.
