20090282984 | System of Treating Odor and Hazardous Gas With Rotary Regenerative Heat Exchanger and Its Apparatus - Disclosed is a harmful material treatment system for recovering the energy and removing the harmful material in the process of treating the gas containing the harmful material generated in the multiplex utilization facility, in the display mall, in diverse manufacturing processes and in the vehicle painting process, more particularly, to a harmful material treatment system which can recover the energy contained in the air conditioning facility or in the exhaust gas of the process with an efficiency of more than 90%, for exhausting the inside air to the outside so as to treat the contaminating material such as odor and volatile organic chemicals, and to remove the harmful material with a removal efficiency of more than 90% by adsorbing and concentrating the harmful material with a rotary-type adsorbent. | 11-19-2009 |
20100135198 | APPARATUS FOR MOBILE SATELLITE COMMUNICATIONS AND METHOD OF CONTROLLING COMMUNICATIONS ROUTE - A mobile satellite transmission/reception apparatus and a communications route control method using the same are disclosed. The mobile satellite transmission/reception apparatus comprises: a first antenna unit configured to receive a signal along a first communications route; a second antenna unit configured to receive a signal along a second communications route; and a data processor configured to compare cyclic redundancy check (CRC) values with respect to packet streams of signals respectively received by the first and second antenna units, and change communications route to one of the first and second communications routes if packets having the same CRC value are detected. | 06-03-2010 |
20100135327 | APPARATUS AND METHOD FOR GENERATING FRAME FOR MPE-FEC DECODING - An apparatus and method for generating frames for MPE-FEC decoding are disclosed. The apparatus for generating frames for MPE-FEC decoding includes: a packet reception unit configured to receive a packet; a packet attribute inspection unit configured to inspect whether or not the received packet forms a header part of a section; and a frame generation unit configured to generate a frame according to different methods depending on whether or not the packet forms a header part of a section. | 06-03-2010 |
20110149906 | METHOD FOR REDUCING PACKET ORDERING TIME OF LAYER 3 HANDOVER AND MOBILE SATELLITE TERMINAL USING THE SAME - There are provided a method for reducing a packet ordering time of layer 3 handover and a mobile satellite terminal using the same. The method for reducing a packet ordering time of layer 3 handover of a mobile router in a home agent of a satellite network connected with the mobile router includes: transmitting a first packet and a second packet to the mobile router through a satellite link of the mobile router; transmitting a sequence control packet to the mobile router through the satellite link; and transmitting a third packet to the mobile router via a wireless link of the mobile router. The sequence control packet provides a reference time for rapidly reordering the second and third packets which reach the mobile router in a reverse sequence. | 06-23-2011 |
20140064118 | APPARATUS AND METHOD FOR CONTROLLING SATELLITE TERMINAL - Provided is a satellite terminal controlling apparatus and method that may measure a packet loss rate of a return link at a central station, may determine a modulation and coding (MODCOD) value of the return link using the packet loss rate, and may control MODCOD of a satellite terminal with respect to the return link. | 03-06-2014 |
20140082674 | APPARATUS, SYSTEM, AND METHOD FOR PROCESSING DATA - Provided is a data processing apparatus and method that may initialize baseband frame data that is newly input, and may randomize the baseband frame data based on a byte unit. Also, provided is a data processing system and method that may configure baseband frame data by randomizing the baseband frame data based on the byte unit in performing mode adaptation and stream adaptation with respect to a received transport stream (TS) packet, and may perform channel encoding of the baseband frame data. | 03-20-2014 |
20140150035 | APPARATUS AND METHOD FOR RECEIVING SATELLITE BROADCAST - Provided is an apparatus and a method for receiving a satellite broadcast. The method may include estimating a channel using signal-to-noise ratio (SNR) information being received, determining a video signal to be received among at least two video signals based on the estimated channel, and controlling selective reception of the determined video signal. | 05-29-2014 |
20140245361 | MULTILEVEL SATELLITE BROADCASTING SYSTEM FOR PROVIDING HIERARCHICAL SATELLITE BROADCASTING AND OPERATION METHOD OF THE SAME - Provided is a multilevel satellite broadcasting system for providing a hierarchical satellite broadcasting, including a demodulator to demodulate a transmitted multilevel compression stream based on a modulation parameter, a hierarchical video decoder to receive the demodulated multilevel compression stream, and a channel predicting and controlling unit to process at least one of channel prediction and channel control with respect to the demodulated multilevel compression stream based on channel information of the demodulator. | 08-28-2014 |
