SK Telecom Co., Ltd. is a South Korean wireless telecommunications operator, controlled by the SK Group, one of the country's largest chaebols.SK Telecom is a provider of mobile service, with 50.5% share of the South Korean market as of 2008. Since its establishment on March 29, 1984, the company has evolved from a first generation analog cellular system, to second generation CDMA, then to the world's first third-generation synchronized IMT-2000 cellular system. SK Telecom also became the world’s first carrier to commercialize HSDPA in May 2006.The company’s current services include NATE, a wired and wireless integrated multi-Internet service, June, a multimedia service, MONETA, a financial service, Telematic service such as NATE Drive and even Digital Home service. In 2004, SK Telecom launched Hanbyul, the world’s first DMB satellite. SK Telecom's subsidiary TU Media provides satellite DMB. SK Telecom also offers a variety of internet services, many through its subsidiary SK Communications. Cyworld is one of the most popular blogging services in South Korea and NateOn is one of the most popular instant messengers. Wikipedia.

A method performed by an apparatus for intra-predicting a current block in the unit of subblocks, comprises: determining an intra prediction mode of the current block among a plurality of intra prediction modes; identifying the subblocks split from the current block; and sequentially reconstructing the identified subblocks using an intra prediction mode identical to the determined intra prediction mode of the current block, wherein a subblock to be reconstructed is predicted using at least one pre-reconstructed neighboring subblock in the current block.

A video decoding method performed by a video decoding apparatus includes: generating a quantized frequency transform block by decoding a bitstream; reconstructing a residual block by inversely quantizing and inversely transforming the quantized frequency transform block; generating a prediction block corresponding to a current block; reconstructing the current block by adding the generated prediction block to the reconstructed residual block; and performing a deblocking filtering with respect to a boundary between subblocks within a frame including the reconstructed current block, by allowing numbers of filtered pixels in a first block of the subblocks and a second block of the subblocks that engage in the filtering to be different depending on one or more predetermined criterion.

A video encoding apparatus includes an inter predictor to check for whether predetermined candidate adding conditions are satisfied, add into a merge candidate set including merge candidates corresponding to neighboring blocks of a current block, a combined bi-predictive motion parameter, the combined bi-predictive motion parameter generated by combining a list 0 motion parameter of a first available candidate block and a list 1 motion parameter of a second available candidate block, when the predetermined candidate adding conditions are satisfied, and predict the current block by using a motion parameter corresponding to a merge candidate selected from the merge candidate set, to thereby generate a predicted block for the current block. Herein, the merge candidate set corresponds to a maximum number of the merge candidates, the maximum number of the merge candidates corresponding to information on the number of the merge candidates included in a bistream.

Provided is a method and apparatus for discontinuously transmitting/receiving packets for low-power consumption of a terminal in a cellular system for packet transmission. The present research provides a method and apparatus that can perform a low-power consuming operation when a terminal is in active state in a cellular system. The method for discontinuously transmitting/receiving packet data to reduce power consumption of a terminal in a cellular system, including the steps of: a) establishing discontinuous reception/transmission (DRX/DTX) parameters including discontinuous DRX/DTX cycle information for terminals operating in a transmission suspension mode, which is a sub-state of an active state; and b) performing DRX/DTX based on the DRX/DTX parameters in the terminals operating in the transmission suspension mode.
