For example, the service provider 20 may package the first terrestrial broadcast, the second terrestrial broadcast, the cable MSO, the satellite broadcast, various Internet broadcasts, applications, and the like to provide the package to the user.

Meanwhile, the service provider 20 can provide a service to the client 100 using a unicast or multicast method.

In the unicast method, data is transmitted between a sender and a receiver in a one-to-one manner. For example, in a case of a unicast method, when a receiver requests data from a server, Lt; / RTI >

The multicast scheme is a scheme for transmitting data to a plurality of receivers of a specific group. For example, the server can transmit data to a plurality of receivers registered in advance. An Internet Group Management Protocol (IGMP) protocol may be used for multicast registration.

The network provider 30 may provide a network for providing the above-mentioned service to the client 100 and the client 100 may establish a home network end user (HNED) It is possible.

Conditional access or content protection may be used as a means for protecting contents transmitted in the above system. As an example of the conditional access and content protection, a scheme such as a cable card (CableCARD) and a DCAS (Downloadable Conditional Access System) may be used.

In this case, the client 100 may be a content provider, and the content provider 10 may receive content from the client 100. In this case, . Accordingly, an interactive content service or a data service may be possible.

The service manager 123 receives the service information of the channel from the PSI & PSIP and / or SI decoder 114 and can set the audio / video PID (Packet Identifier) of the selected channel in the demultiplexer 115.

The service discovery manager 120 may provide information necessary for selecting a service provider that provides the service. For example, when the service discovery manager 120 receives the signal related to the channel selection from the service manager 123, the service discovery manager 120 can find the service using the received signal.

Meanwhile, the service control manager 119 is responsible for selecting and controlling services. For example, when a user selects a live broadcasting service such as an existing broadcasting system, the service control manager 119 uses IGMP or RTSP, , It is possible to select and control the service using the RTSP.

The RTSP protocol can provide a trick mode for real-time streaming. The service control manager 119 initializes a session through an IMC gateway using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP) And manage it.
