The network interface unit 602 receives packets received from the network and transmits the packets to the network. That is, the network interface unit 602 receives an IP packet for transmitting broadcast data from the service providing server through the network. Here, the broadcast data includes content, an update message indicating whether content is updated, metadata, service information data, and software code.

The IP manager 604 is involved in delivering packets from a source to a destination with respect to packets received in the digital broadcast receiver 600 and packets transmitted from the digital broadcast receiver 600. [ The IP manager 604 classifies the received packets so as to correspond to the appropriate protocols and transmits the packets classified as the service delivery manager 606, the service discovery manager 624, the service control manager 626, and the metadata manager 628 . For example, when the IP manager 604 receives the update message, the IP manager 604 may output the received update message to the service control manager 626. The IP manager 604 may also forward a message requesting the update message output by the service control manager 626 to the service provider.

The service delivery manager 606 is responsible for controlling the received service data. For example, RTP / RTCP (Real-Time Transport Protocol / RTP Control Protocol) can be used to control real-time streaming data. When the real-time streaming data is transmitted using the RTP, the service delivery manager 606 parses the received data packet according to the RTP and transmits it to the demultiplexer 608 or to the service manager 620 And stores it in the content channel database unit 630. And feedbacks the network reception information to the server providing the service using the RTCP.
