Provided is an apparatus for motion estimation of video data. The apparatus includes a sum of absolute difference (SAD) calculating unit which receives video data and calculates an SAD for each frame of the video data, a motion vector calculating unit which divides each frame of the video data into macroblocks or sub-macroblocks having a predetermined size and calculates a motion vector estimation value using motion vectors or prediction vectors of macroblocks or sub-macroblocks adjacent to each macroblock or sub-macroblock, and a motion updating unit which performs motion estimation on the video data using an SAD calculated by the SAD calculating unit for the macroblocks or the sub-macroblocks adjacent to each macroblock or sub-macroblock having the predetermined size and the motion vector estimation value of the motion vector calculating unit.

In an apparatus to measure a path loss between base-station and repeater, forward and reverse link automatic power controlled repeater of the present invention is comprising that a repeater control part means for controlling the repeater run and to process forward and reverse gain of the repeater using received information; a mobile communication modem means for transferring base-station signal information and base-station power transmission, and providing a wireless connection pathway of the repeater control part; a repeater element management system (EMS) means for transferring an information of base-station with extract to the repeater control part and to exchange of information with the repeater control part to control a repeater through the modem.
摘要:
Provided are a packet processing apparatus and method used when an output bitstream of an embedded codec is divided into a plurality of packets and transmitted accordingly, and more particularly, an efficient packet processing apparatus and method which can reduce deterioration of sound quality which may occur when a packet required for the reproduction of a voice signal is not received due to different arrival times of a plurality of packets at a receiving end if an output bitstream of an embedded codec is divided into the packets and transmitted accordingly through a path or a plurality of paths. In particular, an apparatus for processing packets of an embedded codec is provided. The apparatus includes a packet reception unit receiving packets, a layer information unit identifying layer information from received packets, a bitstream determination unit using the received packets, and a bitstream generation unit generating a new bitstream. The apparatus is used to provide a voice and multimedia service using an embedded codec in a packet network.

A method and system for supporting an XQuery trigger in XML-DBMS based on relational DBMS is provided. In an Ubiquitous environment where XML data are incessantly generated by an enormous number of objects, so as to overcome inconvenience and its resultant reduction of performance in which a user should query after checking a change of XML-DBMS one by one, in XML-DBMS based on relational DBMS, the present invention supports an XQuery trigger technique based on SQL trigger automatically executing insert, update and delete statements, and a storage or external procedure related with the change of data when a change of data is generated at a specific table in a conventional relational DBMS.

Disclosed are efficient municipal wastewater treatment apparatus and process characterized in that the nitrogen is removed by nitrification and denitrification reaction in the cyclic aeration reactor wherein Anaerobic state, Anoxic state and Oxic state are change into time concept in a single reactor, and the untreated organic materials are further removed by the 24-hour-continuous reactor.
摘要:
There is provided a speech coding/decoding apparatus and method, in which the input speech signals are classified into several classes in accordance with characteristics of the input speech signals and the input speech signals are coded using frame sizes, quantizer structures, and bit assignment methods corresponding to the determined classes, or in which the frame sizes can be adjusted in accordance with network conditions or codec type of a counter part. Therefore, by optimally adjusting the frame size, the quantizer structure, and the bit assignment method in accordance with the characteristics of input speech, it is possible to improve the performance of the speech coding apparatus, and by adjusting the frame size in accordance with the speech codec type of a counter part, it is also possible to reduce the total end-to-end delay.
