An analog translator for the IEEE 1394 serial bus by which it is possible to use an analog device as a part of a home network when the analog device is connected to the IEEE 1394 serial bus and a translating method thereof are provided. The analog translator includes a plurality of ports to which analog devices are connected, a status register for showing which analog devices are connected, a configuration ROM for storing the information on the connected analog devices, a controller for setting the corresponding bit of a status register assigned to an analog device, reading the bit status of the set status register, and recording connection information of the analog device to the configuration ROM which refer to the bit status of the status register, when an analog device is connected to the port, a 1394 interfacing unit for receiving a packet data from the IEEE 1394 bus, checking whether the packet data corresponds to the node thereof, and disintegrating packet data and thus removing a header from the packet data when the packet data corresponds to the node thereof, a storing unit for storing payload data removed of a header from the 1394 interface, a destination unit extractor for decoding the payload data of the storing unit and extracting information on the destination analog device of the payload data, and a data translating unit for translating the payload data removed of the information on the destination analog device into analog signal. According to the present invention, it is possible to interface both analog and digital devices in realizing an IEEE 1394 home network. |
