Abstract:
PURPOSE: A coupon mobile system and method thereof are provided to supply an IPTV service in which an oneself is registered even if a user uses a set-top box of other user which is not oneself set-top box. CONSTITUTION: A set-top box checks whether a service authenticating information is updated to a service server(S410). Whether the service authentication information is downloaded to a mobile storing medium is checked(S415). The set-0top box can set a target in which service authentication information is stored to the service server(S420). The set-top box can set a target in which service authentication information is stored to the mobile storing medium(S425). The set-top box checks whether the mobile storing medium is combined with the set-top box(S430).
Abstract:
PURPOSE: An efficient VOD service system and method thereof which uses unicast/multicast on the internet network are provided to supply efficient video on demand by allocating a connection management method between a server and a user terminal. CONSTITUTION: An MEF(Multicast Efficency Factor) confirmation unit(620) confirms the multicast efficiency factor of the corresponding content according to the content request from a client. A content transmitter(630) transmits the content to multicast or unicast through the network. The multicast efficiency factor includes efficiency measure of multicast transmission about unicast transmission of the content.
Abstract:
PURPOSE: A magnetic field communication method of an online electric vehicle and system thereof are provided to measure the moving speed of an online electric vehicle to predict a charging segment that a moving vehicle passes in consideration of data transmission delay time, a magnetic field communication distance, and a predicted vehicle passing location error according to the moving speed. CONSTITUTION: A magnetic field communication method of an online electric vehicle comprises the following steps. A magnetic field communication module buried in a road receives speed information from a magnetic field communication module of a moving vehicle(S10). The magnetic field communication module buried in the road updates the speed information of the moving vehicle and transmits the speed information to an inverter(S30). The inverter controls the number of operating magnetic field communication modules buried in the road at a predicted vehicle passing location according to the speed information of the moving vehicle.
Abstract:
PURPOSE: A recombinant microorganism with butanol productivity by deletion or inactivation of a specific gene is provided to improve butanol productivity per hour without production of other by-products. CONSTITUTION: A method for preparing a recombinant microorganism with enhanced butnol productivity comprises a step of deleting a gene encoding an enzyme which converts acetyl CoA to acetate in a host microorganism. The enzyme is acohol dehydrogenase, aldehyde dehydrogenase, and alcohol/aldehyde dehydrogenase.
Abstract:
PURPOSE: A method for preparing a recombinant mutant microorganism is provided to enhance butanol, ethanol, and isopropanol productivity. CONSTITUTION: A method for preparing a mutant microorganism comprises a step of preparing a mutant microorganism with enhanced concentration or changed kind of metabolic products selected from the group consisting of acetone, butyric acid, acetoin, hydrogen, and straight or side alcohol of 2-10 carbon atoms. A host microorganism is Clostridium sp.
Abstract:
PURPOSE: A distinguishing method, a user identification server and a service server for an IPTV service is provided to hold one STB in common for many users by offering a user definition environment fixing to the user corresponding to a telephone number inputted to the IPTV STB. CONSTITUTION: A generating unit(11) creates a user binding information which is mapped to a STB ID based on a specific user information inputted from the STB(Set-Top Box). A binding information storage unit(12) stores the user binding information in a user ID database(20). The first identification part(13) searches the user binding information in the user identification database based on a specific user information inputted through an initial display for an IPTV(Internet Protocol TV) service. The first identification part distinguishes an STB user in which the specific user information is mapped.
Abstract:
PURPOSE: A terminal information communication device for a multimedia streaming service adaptive to a terminal and a method thereof are provided to enable a multimedia server to supply a multimedia streaming service corresponding to transmitted terminal information, thereby providing a multimedia streaming service suitable for a use environment. CONSTITUTION: A mobile phone terminal(10) includes terminal information in an SIP message when transmitting the SIP message. SIP proxy servers(21,22) transfer the SIP message to a multimedia server(30). The SIP proxy servers transmit multimedia contents transmitted from the multimedia server to the mobile phone terminal. The multimedia server analyzes the SIP message to extract the terminal information.

Abstract:
A method for providing a video on demand broadcasting service in a portable internet network is provided to map a connection management technique between a base station and a user terminal for channel assignment for broadcasting, thereby providing a more efficient video on demand broadcasting service. A client group(100) provides a wireless communication service to a subscriber. A portable internet network(102) assigns transmitted VoD contents to the client group. A VoD service server(104) transmits the VoD contents to a portable internet through multi channel multicast or unicast. A client information DB(106) stores user information of the client group.
