Abstract: A device for transmitting a media service in a hybrid network, which is a combination of a broadcasting network and a communication network, includes a streaming server, a streaming client, a multiplexer, and a transmitter. The streaming server generates media segments including media data and a metadata file including temporal order information and downloading and reproduction information of the media segments corresponding to a plurality of profiles. The streaming client selects a profile according to a transmission bit ratio appropriate for a broadcasting resource allocation state, requests a media segment with quality that is suitable for the broadcasting resource allocation state from the streaming server, and downloads the same. The multiplexer multiplexes part of information of the metadata file on the profile selected from among the media segment and the metadata file of the plurality of profiles to generate a baseband frame.

Abstract: Disclosed is a method and device for transmitting media data in a digital broadcasting system for allocating media data to a superframe, and transmitting a superframe in which a time length of media data corresponds to a time length of the superframe.

Abstract: Disclosed is a method and device for providing a broadcasting service, including: acquiring signaling information from a broadcasting signal received from a broadcasting network; acquiring information on a hybrid broadcasting service based upon the signaling information; and determining whether a component to be received through a communication network exists based upon information on the hybrid broadcasting service.

Abstract: A hybrid broadcasting transmitting apparatus generates signaling information including a stream type of a plurality of broadcasting programs and a transmitting network type of the plurality of broadcasting programs, transmits signaling information and a broadcasting stream corresponding to a portion of a plurality of broadcasting programs through the communication network, and transmits signaling information and a broadcasting stream corresponding to the remaining portions of a plurality of broadcasting programs through the broadcasting network.

Abstract: A terminal device for broadcasting and communication creates a virtual network interface, connects the virtual network interface and a communicating unit of the terminal device for broadcasting and communication to each other, connects the virtual network interface and a broadcasting receiver of the terminal device for broadcasting and communication to each other, activates the virtual network interface, and processes transmitted and received packets via a broadcasting network and a communication network through the virtual network interface.

Abstract: A content provider provides content by receiving a request for streaming content from a user, determining whether a streaming file corresponding to the streaming content is stored in the content provider, and if the streaming file is stored in the content provider, providing the internal protocol (IP) address of the content provider to a web browser.

Abstract: A DMB/mobile communication network linkage platform for interactive service, a DMB/mobile communication network integrated receiving terminal using the same and a method thereof are disclosed. The DMB/mobile communication network linkage platform includes: a DMB basic software module for providing DMB basic functions corresponding to a handset basic software of the wireless internet standard platform; a DMB HAL engine as a lower abstract layer for providing a function of controlling DMB and a function for interactive communication; a DMB runtime engine for providing an environment for DMB APIs; and a DMB API module for providing DMB basic APIs corresponding to basic APIs of the wireless Internet standard platform.
