Abstract: A method and apparatus for providing a trick play service in a hypertext transfer protocol (HTTP) adaptive streaming (HAS) architecture for adaptively streaming media data according to fluctuation of a streaming environment are provided. The method at a server includes: generating a media presentation description (MPD) file including information about at least one piece of trick play data; transmitting the MPD file to a client; and transmitting the at least one piece of trick play data to the client in response to a request by the client based on the MPD file. The method at a client includes: receiving a media presentation description (MPD) file including information about at least one piece of trick play data; and receiving the at least one piece of trick play data from a server based on the MPD file.

Abstract: A peer-to-peer (P2P) network system is provided. The P2P network system includes a server which groups transmission unit packets constituting a data stream into a group according to a predetermined time unit and provides the group of the transmission unit packets, and a plurality of peer devices which transmit and receive the group of the transmission unit packets.

Abstract: A method and apparatus for recommending information is provided. When a client accesses a server and requests information, the server determines whether the client is included in a meaningful set (MS) and generates first preference information of the client based on an access history of the client, or based on additional information directly input by the client. Then, the server selects a number of neighborhood groups including clients having preferences similar to a preference of the client, and generates and transmits first item information on a number of items preferred by the clients of the neighborhood group to the client. The client extracts second item information to be recommended to a user by filtering the first item information with second preference information. Information is filtered respectively by the server and the client by using different algorithms. Accordingly, it is possible to improve the accuracy and speed of recommending information.

Abstract: Provided are content reproduction and content publication methods and apparatus therefor. The content reproduction method selects an advertisement to be inserted in a media content by referring to information about advertisements which are insertable into the media content, inserts the selected advertisement into the media content received from a media server, and reproduces the media content having the selected advertisement inserted therein, thereby enabling a client reproducing the media content to dynamically configure the advertisements being inserted to the media content, according to a user selection. Thus, a content user can actively select advertisements to be watched.

Abstract: Provided are an apparatus and method for sharing a broadcasting program, and more particularly, an apparatus and method for sharing a broadcasting program via the Internet. The apparatus includes a list manager which manages a list of devices storing a broadcasting program and a device information transmitter which transmits information, to a first device, about a second device storing a broadcasting program requested by the first device, wherein the second device divides the requested broadcasting program into time slots and transmits each time slot to the first device.

Abstract: An apparatus for reducing PAPR (Peack to Average Power Ratio) in an OFDM (Orthogonal Frequency Division Multiplexing) system includes: an IFFT (Inverse Fast Fourier Transform) unit for performing an IFFT on an input data stream modulated using a specific constellation to generate time-domain signals; a time-domain clipping unit for performing a time-domain clipping on the time-domain signals at a clipping level determined by characteristics of the time-domain signals; an FFT (Fast Fourier Transform) unit for performing an FFT on the clipped time-domain signals to generate frequency-domain signals; and a frequency-domain clipping unit for performing a frequency-domain clipping on the frequency-domain signals. The time-domain clipping reduces in the OFDM system, and the frequency-domain clipping reduces distortions generated by the time-domain clipping.

Abstract: Method and apparatus for receiving data by using a plurality of pieces of information managed by a server that manages information about data that can be received via one or more peer-to-peer (P2P) networks and information about peers respectively connected to each P2P network.

Abstract: Provided are a method and apparatus for transmitting/receiving broadcast data via a peer-to-peer (P2P) network, in which information regarding a list of a plurality of pieces of broadcast content that are broadcast via one broadcast channel is provided to a server in the P2P network, and the broadcast data is transmitted/received according to the provided list.

Abstract: A message management service server includes a messaging group information storage unit for storing messaging group information, a VM environment setting information storage unit for storing user-set environment information, a group special service code management unit for managing group special service code information, a group message history storage unit for storing messages transmitted or received between users of each messaging group, a VM application creation unit for creating the VM application, a VM application download unit for downloading the created VM application to the mobile communication terminal of the user, a SMS message transmission unit for transmitting a short message to the mobile communication terminals of the users of a messaging group of a specific special service code, and a message posting unit for storing transmitted or received messages via the group history storage unit and posting the messages according to a message posting environment of a corresponding group.

Abstract: A method and apparatus for a credit card and debit card transaction terminal including a processor, a display and a memory. A card reader is configured to read data stored on a portable memory medium. An operator interface is produced by an operator interface program and executable by the processor. The operator interface being displayable on the display in an operator language. A customer interface is produced by a customer interface program and executable by the processor. The customer interface being displayable in a customer language. A language identification module is stored in the memory and executable on the processor. The language identification module is configured to select the operator language and to select a customer language in which displayable for the operator and customer, respectively. The operator and customer languages are selected from a plurality of languages stored in the module. The operator and customer languages are different.

Abstract: Disclosed herein are a system and method for providing advertisement messages. The system includes a message transmission condition setting unit, a Virtual Machine (VM) application provision unit, a message transmission target extraction unit, and a message transmission unit. The message transmission condition setting unit classifies message transmission conditions according to a user and stores the classified message transmission conditions in the DB, based on a preset message transmission condition menu. The VM application provision unit extracts the VM application and transmits the extracted VM application to the mobile communication terminal. The message transmission target extraction unit extracts an advertisement message transmission target based on message transmission conditions for the respective users.
