摘要:
A retransmission apparatus is provided that uses a packet method for a DMB service and includes: a DMB receiver for receiving DMB data from a medium; a DMB transmission mode release unit that outputs an MPEG-2 TS by releasing a DMB transmission mode in the DMB data received from the DMB receiver; a channel information extractor that extracts channel information contained in a Fast Information Channel (FIC) of the DMB data in the DMB transmission mode release process of the DMB transmission mode release unit; a data information extractor that receives the MPEG-2 TS from the DMB transmission mode release unit and extracts data information indicating a location of an elementary stream from the received MPEG-2 TS; a channel information database (DB) that stores the channel information extracted by the channel information extractor and the data information extracted by the data information extractor as channel data; a first IP streamer that IP-streams the MPEG-2 TS output from the data information extractor; and a second IP streamer that IP-streams the channel data stored in the channel information DB.
