A network service platform apparatus employing an IEEE 1394 protocol is disclosed. The network service platform apparatus includes a first optical transceiver connected to an external service gateway to receive downstream data from the external service gateway and transfer upstream data to the external service gateway, a first IEEE 1394 physical unit connected to the first optical transceiver to perform a physical layer operation of an IEEE 1394 protocol with respect to the downstream data, and to transfer the upstream data to the first optical transceiver, and an IEEE 1394 link unit connected to the first IEEE 1394 physical unit to deliver isochronous data of the downstream data by performing a link layer operation of the IEEE 1394 protocol, and to send asynchronous data to be delivered to the service gate to the first IEEE 1394 physical unit as upstream data by performing the link layer operation of the IEEE 1394 protocol with respect to the asynchronous data. In addition, the home network service platform apparatus includes an Application Protocol Interface connected to the IEEE 1394 link unit to output IEEE 1394 isochronous data, an IEEE 1394 bridge unit having a first bus connected to the first IEEE 1394 physical unit and a second bus connected to the first IEEE 1394 physical unit in order to transmit/receive data between the first bus and the second bus, and a second IEEE 1394 physical unit which is connected to the IEEE 1394 bridge unit through the second bus and connected to an IEEE 1394 unit using a bus independent of the IEEE 1394 apparatus.
