Abstract: PURPOSE: A wireless network system for receiving digital broadcasting signals is provided to easily transmit video signals using a copy guard system and an interface. CONSTITUTION: A wireless network system for receiving digital broadcasting signals includes a TV broadcasting receiver, a wireless video transmission/reception module, and a display. The TV broadcasting receiver receives A/V signals, tunes and channel-decodes the A/V signals to transmit the signals to the wireless video transmission/reception module through an interface. The wireless video transmission/reception module accepts the A/V signals from the TV broadcasting receiver and processes the accepted signals to transmit the processed signals to the display through an interface. The display receives the A/V signals from the wireless video transmission/reception module to display the signals.

Abstract: PURPOSE: A method for distributing digital contents using a single CD is provided to sell the single CD storing one or two songs, a key, and an ID code, and enable a user buying the single CD to download the digital contents by using the key and the ID code stored in the single CD. CONSTITUTION: In case that a user terminal is connected to a digital contents providing server, the key and the ID code stored in the single CD installed to a CD player are read/inputted to the digital contents server(206). In the case that the key and the ID code are not stored in a database, the key and the ID code are stored in the database, and it is judged that the user terminal requests the download of the digital contents(212). In the case that the download of the digital contents is requested, the digital contents are displayed/selected by receiving the user information from the user terminal(220). In the case that the selection of the digital contents is completed, the corresponding digital contents are downloaded to the user terminal(230).

Abstract: PURPOSE: A method for efficiently processing packets in a home gateway system is provided to consider priorities of the packets in a home gateway, and to consider situations of a device connected to a home network, thereby efficiently processing home network packets. CONSTITUTION: A system confirms whether LGIs(LAN Gateway Interfaces)/WGIs(WAN Gateway Interfaces) are ready to receive packets. If so, packets having higher priorities and standing by in a packet list of a home gateway are transmitted to the LGIs/WGIs. If the LGIs/WGIs are not ready to receive the packets, the priorities of the packets are reconfirmed to insert the packets into the packet list. The system inserts the packets inputted from the LGIs/WGIs into the nearest portion of packets having higher or the same priorities.
