摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
