ABSTRACT:
The present invention relates to a system and method for retransmitting high definition contents broadcasted on a plurality of channels to IP-supported devices such as a digital media player (DMP), a mobile phone, personal computer (PC), etc. which are connected through a DLNA network. The method for retransmitting the broadcasted high definition contents includes the steps of generating a virtual item by converting channel information for a digital TV broadcast into an Extensible Markup Language (XML) file format, transmitting the virtual item to the DMP, determining whether there is a request for a personal TV service (PTS) from the DMP, tuning to a channel corresponding to the PTS if there is the request for the PTS, storing and packetizing a digital TV broadcast stream received through the PTS channel, and transmitting the packetized digital TV broadcast stream to the DMP.
