Abstract:
The present invention relates to a method and apparatus for supporting location registration and mobility for each service flow in relation to a Mobile Node (MN) having a plurality of wired/wireless network interfaces in a wired/wireless integrated network environment. A method includes receiving a location registration message from a specific Handover Control Agent (HCA) connected to an MN, determining a movement of a flow, configured in another HCA to which the MN is connected, based on predetermined static flow binding information or a network status, sending a location registration Ack. message, comprising information on a HCA in which the flow is configured and to which a Corresponding Node (CN) is connected, to the specific HCA, and sending a location notification message, comprising information on the specific HCA to which the flow will be moved and to which the CN is connected, to the HCA.
Abstract:
An apparatus of estimating a position of a moving object creates a global map for a space over which the moving object is moving, on the basis of environment information on moving distance, measured distance, captured image and GIS data, and attribute and position of obstacles within the space. The method also creates a local map on the basis of the environment information obtained from around the moving object, and estimates a position of the moving object on the global map through matching of the local map and the global map.

Abstract:
A system and method for analyzing an online game packet are disclosed. The system for analyzing the online game packet includes a capturing unit that captures a packet transmitted between a client terminal and a game server, and an analysis unit that analyzes the packet captured by the capturing unit, and defines, according to an analyzed result, a data field included in the packet as a static field having the same field structure or a dynamic field having a field structure according to a reference field defining an arrangement rule of a field or a field structure according to a user's request. According to the present invention, the data field of the captured packet may be defined for each type according to structural characteristics, thereby automatically analyzing the packet.
Abstract:
Provided is a system and method for front wave field synthesis (WFS) to provide a surround sound with a reduced number of loudspeakers. An apparatus for encoding a front WFS signal in the front WFS system may include a content receiving unit to receive WFS content including the first channels corresponding to a front array speaker and the second channels corresponding to a rear surround sound speaker, and an encoding unit to encode the first channels and the second channels using a multichannel encoder corresponding to the number of the channels included in the WFS content.
Abstract:
Disclosed are a system and a method for performing buoyance of a 3D hologram image on a hologram display screen in a projection mode. A system of displaying a digital hologram includes: a composite hologram unit configured to generate a hologram array by receiving hologram data of a fringe pattern and by compositing background image and a foreground image using the received fringe pattern; a hologram projection unit configured to project a hologram image through a wide-angle lens by applying a light to the hologram array; and a hologram display unit configured to perform space buoyance of the hologram image projected by the hologram projection unit on a 3D hologram display screen. The digital hologram content is managed in real time by using the present disclosure, and transmission of the digital hologram content to a remote place and site adaptive display of hologram image media may be achieved.
Abstract:
The present invention relates to an apparatus and method for simultaneous channel estimation in a digital broadcast system based on a single frequency networkThe present specification encloses a receiver simultaneously acquiring channel responses for each subchannels including a certain number of pilot subcarriers in the frequency and time domain direction from frames transmitted with at least one signalIn the present invention, a receiving apparatus in the single frequency broadcast network may simultaneously estimate the channels of adjacent transmitters, and receiving CNR is enhanced by detecting MIMO signal by the estimated channel.
Abstract:
Disclosed is a technology for storing snapshot images capable of maximizing the reading performance of an SD/MMC card at the time of recovering the snapshot images and minimizing the booting time of a system. A method for storing snapshot images includes: preparing the snapshot images, attempting to allocate continuous reference blocks, in which a number of blocks corresponding to the predetermined number of reference blocks is continuous in a non-volatile memory unit, storing the snapshot images in the allocated continuous reference blocks when the allocation of the continuous reference blocks succeeds, and preparing the snapshot image storage information as a swap table and storing the prepared swap table in the non-volatile memory unit.
Abstract:
Disclosed are an apparatus and a method for normally receiving data by accurately estimating and compensating for a frequency offset for a wireless frequency channel through which data are transmitted in a communication system under wireless frequency environment. In the present invention, data transmitted through the wireless frequency channel are received, the frequency offset in the wireless frequency channel from the receive data is estimated based on an interpolation scheme using the periodogram, and the frequency offset is compensated to receive the data by frequency-synchronizing with the wireless frequency channel.
