Abstract: An apparatus and method for providing an interactive service to devices using different digital broadcast middleware standards are provided. The apparatus includes an execution information providing module which provides execution information regarding an application that has been executed in a first device using a first middleware standard so that the application can be executed in a second device using a second middleware standard; and a request execution module which receives a request issued by the second device during the execution of the application in the second device, and performs an operation corresponding to the received request.

Abstract: An access device and method for preventing transmission of copyrighted contents to an external network and a method for the same. The access device includes a packet-header analyzer analyzing a header of a packet received from a home network device, a copyrighted-content sensor detecting whether the packet includes copyrighted content as a result of the analysis, an address converter for converting a packet source IP address into an IP address supported by the external network if a packet destination address is an external network address as a result of the analysis, a mapping-table generator generating a mapping table for managing a mapping a relationship between the packet source IP address and the converted IP address, and a packet transmitter transmitting the packet to the IP address supported by the external network and discarding the packet to block transmission of the copyrighted content to the external network if the copyrighted-content sensor detects that the packet includes the copyrighted content.

Abstract: A fast adaptive channel converting method and apparatus, and a computer readable recording medium having recorded thereon a program to execute the fast adaptive channel converting method. The fast adaptive channel converting method includes generating adjacent channel data by pre-signal processing an adjacent channel signal of a reference channel, receiving a channel change request from a user, searching for channel data corresponding to a changed channel in the adjacent channel data, and reproducing the searched channel data. Unlike a conventional technology, the fast adaptive channel changing apparatus and method prevents a screen blank time that may occur while changing a channel in a digital broadcast receiving apparatus, and thus boredom or inconvenience of a user can be removed. Also, when a channel is changed by using a preferred channel list, a channel search time can be remarkably reduced, and the user can easily watch a program of a preferred channel.

Abstract: A data-broadcast-receiving apparatus and a display apparatus are disclosed. The data-broadcast-receiving apparatus includes an application-classifying module that classifies a predetermined broadcast-service application into an execution application and a presentation application, an application-executing module that executes the execution application, and a communication module that transmits the presentation module. The display apparatus includes an OpenCable Application Platform (OCAP) browser that browses a predetermined broadcasting service using OCAP-HTML, a communication module that receives a predetermined application corresponding to the browsing operation, and an application-presenting module that executes the received application.

Abstract: A streaming service providing method adaptive to dynamic network changes is provided. The streaming service providing method includes requesting a quality of service (QoS) adapter to provide adaptive services if a QoS manager, which allocates network resources among QoS devices processing media streams, does not accept a request to provide the adaptive services, wherein the QoS adapter determines a level of the adaptive services supportable by a network; and providing the adaptive services to the network.

Abstract: A method and apparatus are disclosed for providing content services in an A/V network supporting web service techniques. An A/V gateway includes a content information requesting unit which requests information about contents to be provided by web services on a distributed network when a predetermined condition is satisfied; a TCP/IP transceiver which receives an ML document including the information about the contents as a response to the request from a service providing device providing the web services; a web service content managing unit which analyzes the ML document including the information about the contents, and generates a reconstructed ML document on the basis of the analysis result; a SOAP server transceiver which transmits the reconstructed ML document; and an A/V network transceiver which transmits a content stream corresponding to the information about the contents.

Abstract: A data transmission method and a data transmission system using an improved network address translation method. The data transmission method includes requesting a real-time service from a multimedia device to a home gateway within a home network; inputting a binary code corresponding to the multimedia device to a service type field indicating priority information of data when the home gateway forms a mapping table used for conversion of addresses; the home gateway requesting setting of an IP address of the multimedia device from a service provider; setting the IP address including the binary code corresponding to the multimedia device according to the request of setting the IP address; and the service provider transmitting a data packet including the binary code corresponding to the multimedia device. The method is applied to the selective IP packet, thereby shortening the transmission time of real-time data packets for multimedia.

Abstract: A system where a home server can recognize a location of a home device in a home network. The home device includes a Radio Frequency Identification (RFID) tag which stores information about the home device, and each plug receptacle constituting the home network has an RFID reader. Accordingly, the RFID reader checks the location of the RFID tag in real time and transfers the information about the RFID tag and a receptacle identifier to a home server, so that the home server recognizes the location of the home device in real time using the information transferred. Therefore, using the transferred information, the home server can recognize in real-time the location of the home device, and also transfer necessary information to the home device.
