2 is a block diagram illustrating a digital device according to an exemplary embodiment of the present invention.

The digital device described herein corresponds to the client 100 of FIG. 1 described above.

The digital device 200 includes a network interface 201, a TCP / IP manager 202, a service delivery manager 203, an SI decoder 204, A demultiplexer (demux or demultiplexer) 205, an audio decoder 206, a video decoder 207, a display A / V and OSD module 208, a service management manager 209, a service discovery manager 210, an SI & metadata DB 211, a metadata manager 212, a service manager 213, A UI manager 214, and the like.

The network interface unit 201 receives the IP packet (s) (IP packet (s)) or the IP datagram (s) ) Is transmitted / received. For example, the network interface unit 201 can receive services, applications, content, and the like from the service provider 20 of FIG. 1 through a network.

The TCP / IP manager 202 determines whether the IP packets received by the digital device 200 and the IP packets transmitted by the digital device 200 are packet delivery (i.e., packet delivery) between a source and a destination packet delivery). The service discovery manager 210, the service control manager 209, the meta data manager 212, the service discovery manager 210, the service control manager 209, and the metadata manager 212. The TCP / IP manager 202 classifies the received packet (s) ) Or the like.

The service delivery manager 203 is responsible for controlling the received service data. For example, the service delivery manager 203 may use RTP / RTCP when controlling real-time streaming data. When the real-time streaming data is transmitted using the RTP, the service delivery manager 203 parses the received data packet according to the RTP and transmits the packet to the demultiplexing unit 205 or the control of the service manager 213 In the SI & meta data database 211. [ Then, the service delivery manager 203 feedbacks the network reception information to the server providing the service using RTCP.

The demultiplexer 205 demultiplexes the received packets into audio, video, SI (System Information) data, and transmits them to the audio / video decoder 206/207 and the SI decoder 204, respectively.

The SI decoder 204 decodes the demultiplexed SI data, that is, Program Specific Information (PSI), Program and System Information Protocol (PSIP), Digital Video Broadcasting Service Information (DVB-SI), Digital Television Terrestrial Multimedia Broadcasting / Coding Mobile Multimedia Broadcasting). Also, the SI decoder 204 may store the decoded service information in the SI & meta data database 211. The stored service information can be read out and used by the corresponding configuration, for example, by a user's request.

[ In other words, the application manager can manage the overall state of the digital device 200, provide a user interface (UI), and manage other managers.

The UI manager 214 provides a GUI (Graphic User Interface) / UI for a user using an OSD (On Screen Display) or the like, and receives a key input from a user to perform a device operation according to the input. For example, the UI manager 214 receives the key input regarding the channel selection from the user, and transmits the key input signal to the service manager 213.

The service manager 213 controls the manager associated with the service such as the service delivery manager 203, the service discovery manager 210, the service control manager 209, and the metadata manager 212.

In addition, the service manager 213 generates a channel map and controls the selection of a channel using the generated channel map according to a key input received from the UI manager 214. [ The service manager 213 receives the service information from the SI decoder 204 and sets an audio / video PID (Packet Identifier) of the selected channel in the demultiplexer 205. The PID thus set can be used in the demultiplexing process described above. Accordingly, the demultiplexer 205 filters (PID or section) audio data, video data, and SI data using the PID.

The service discovery manager 210 provides information necessary for selecting a service provider providing the service. Upon receiving a signal regarding channel selection from the service manager 213, the service discovery manager 210 searches for the service using the information.

The service control manager 209 is responsible for selection and control of services. For example, the service control manager 209 uses IGMP or RTSP when a user selects a live broadcasting service such as an existing broadcasting system, and uses RTSP when selecting a service such as VOD Service selection and control. The RTSP protocol may provide a trick mode for real-time streaming. In addition, the service control manager 209 can initialize and manage a session through the IMS gateway 250 using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP). The protocols are one embodiment, and other protocols may be used, depending on the implementation.

The metadata manager 212 manages the metadata associated with the service and stores the metadata in the SI & metadata database 211.

The SI & meta data database 211 stores the service information decoded by the SI decoder 204, the meta data managed by the meta data manager 212, and the information necessary for selecting a service provider provided by the service discovery manager 210 do. In addition, the SI & meta data database 211 may store set-up data for the system and the like.

The SI & meta data database 211 may be implemented using a non-volatile RAM (NVRAM) or a flash memory.

Meanwhile, the IMS gateway 250 is a gateway that collects functions necessary for accessing the IMS-based IPTV service.
