Abstract: Provided is an error correcting encoder and, more particularly, to an error correcting encoder used for an improved transmission method of the Advanced Television System Committee (ATSC), and a method thereof. The error correcting encoder for digital television broadcasting, which is suggested in the present research, includes a robust encoder for encoding a one-bit input into robust encoded data; a pre-coding block for receiving the robust encoded data and performing pre-coding to thereby produce a pre-coded signal; and a trellis encoding block for performing trellis encoding on the robust encoded data and the pre-coded signal.

Abstract: Disclosed are an apparatus and method for providing an offloading service. A method of providing an offloading service according to an example embodiment includes streaming, to a user terminal including a cellular network receiver and a broadcast network receiver, media content data through a cellular network, transmitting, to the user terminal, an offloading service providing signal for activating the broadcast network receiver of the user terminal through the cellular network, transmitting, to the user terminal, a broadcast signal including connection information of a broadcast network to which the user terminal is to be connected so as to receive the media content data, through the cellular network, and broadcasting the media content data through the broadcast network.
