Abstract:
An Internet protocol (IP)-based integrated customized broadcast service system and method are provided. The IP-based integrated customized broadcast service system includes: a subscriber schedule table providing server generating a subscriber schedule table matching with a time when a user desires to be provided with a broadcast program or IP-based content; and a broadcast server transmitting the broadcast program to the user who desires to be provided with the broadcast program or converting the IP-based content to a broadcast service format that can be watched by the user and transmitting the converted IP-based content to the user who desires to be provided with the IP-based content according to the subscriber schedule table. Accordingly, video on demand (VoD) content, user created content (UCC), and proteur created content (PCC) can be used for broadcasting, so that a variety of broadcast programs can be configured.
Abstract:
Provided is a system and method for providing vehicle parking information using a navigation satellite. The system includes: a monitoring unit for photographing an image of a vehicle parking space and transmitting the image to a parking space checking unit; the parking space checking unit for checking a vacant parking space based on the transmitted vehicle parking space image and transmitting vacant parking space acquisition information to a location information computing unit; and the location information computing unit for creating and transmitting location information of the vacant parking space, which is vehicle parking information, to a navigation satellite based on own location information acquired based on navigation information transmitted from an external navigation satellite and the transmitted vacant parking space acquisition information.
Abstract:
A method for a hybrid service discovery adapting between push-based and pull-based schemes in a mobile ad-hoc network and a system thereof. The method includes periodically transmitting a first control packet for providing service information from a service provider that is capable of providing a service to nodes located in a specified advertisement zone, transmitting a second control packet requesting the service from a service demander to one or more nodes in a network, and transmitting a third control packet including path information of the service provider if at least one of the nodes located within the advertisement zone and the service provider receives the second control packet. The method and the system can reduce the amount of control packet transmission and minimize an end-to-end delay.
Abstract:
An internal voltage generator includes a control section and a switchable internal voltage generating circuit. The control section generates a control signal in response to a bank activation command and a bank activation signal for enabling memory banks. The internal voltage generating circuit receives a reference voltage, and responds to the control signal to output an internal voltage equal to the reference voltage. The control signal is enabled when the bank activation command and the bank activation signal are concurrently enabled. The bank activation signal is generated in response to a partial array self refresh (PASR) signal. The internal voltage may be supplied to banks selected by the bank PASR signal, thereby enabling refresh operations in the entire bank, or an internal voltage adequate to partially enable refresh operations in all the banks may be supplied. Thus, unnecessary power consumption may be effectively controlled.
Abstract:
A channel search method for a vertical handoff in a wireless network environment is provided, the channel search method including: collecting channel information from a first terminal which is provided with a wireless local area network (WLAN) service via a channel connection with a WLAN node; and determining a channel search order for a channel connection between a second terminal and the WLAN node by using the collected channel information. A channel search system for a vertical handoff in a wireless network environment is also provided, the channel search system including: a channel information collection unit for collecting channel information from a first terminal which is provided with a WLAN service via a channel connection with a WLAN node and a search order determination unit for determining a channel search order for a channel connection between a second terminal and the WLAN node by using the collected channel information.
Abstract:
An apparatus and method of saving power using location information, which can control power consumption of a mobile terminal in a sparse cell environment is provided. The power saving apparatus using location information comprises a transceiver for receiving a location information set from a base station having the stored location information set, a controller for receiving the location information set from the transceiver, and activating any one of a plurality of modes by using the location information set, where each of the plurality of modes utilizes a different power consumption level.
Abstract:
In a display apparatus, a spacer maintaining a cell gap between a first substrate and a second substrate is integrally formed to extend from the first substrate, and an adhesive is formed on an upper face of the spacer. The upper face of the spacer is attached to the second substrate by means of the adhesive. An excess adhesive receiving space is defined in and/or above the upper face of the spacer to receive excess amounts of the adhesive that are extruded from between the spacer and the second substrate when the first and second substrates are press joined to each other.
Abstract:
A method and system for eliminating inefficiency caused by active-sleep mode switching in power saving through a sleep mode in a wireless mesh network are provided. The sleep mode is controlled using a virtual Transmission Opportunity (vTXOP) according to TXOP information of a one-hop neighbor node. The sleep mode control takes into account a wireless mesh network environment and leads to power saving.
Abstract:
The present invention relates to an evaporator for an air conditioner of a vehicle, and the major object of the present invention is to provide the evaporator which is capable of decreasing the whole dimension of an evaporator and enhancing a heat exchange performance. To achieve the above objects, an evaporator includes an upper and lower header units comprising a tank member, a partition member, a header plate, an intermediate baffle, a finishing baffle; and a plurality of tubes comprising a front tube portion, a rear tube portion, a connection tube portion; and a wrinkle fin.
Abstract:
An apparatus, method and system are provided for routing a broadcast data frame in a mesh network with multiple mesh portals. In the mesh network, every mesh point selects and registers its default mesh portal. A mesh portal enters its address in a destination address field of a broadcast data frame received from outside of the mesh network and broadcasts the data frame to inside of the mesh network. The mesh point processes a received broadcast data frame relating to its registered mesh portal, thereby preventing the broadcast data frame from being redundantly transmitted in the mesh network.
