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. The transmitter converts the baseband frame into a broadcasting signal and transmits the same through a broadcasting network.
