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.

An object-based 3-D audio system. An audio input unit receives object-based sound sources. An audio editing/producing unit converts the sound sources into 3-D audio scene information. An audio encoding unit encodes 3-D information and object signals of the 3-D audio scene to transmit them through a medium. An audio decoding unit receives the encoded data through the medium, and decodes the same. An audio scene-synthesizing unit selectively synthesizes the object signals and 3-D information into a 3-D audio scene. A user control unit outputs a control signal according to the user's selection so as to selectively synthesize the audio scene by the audio scene synthesizing unit. An audio reproducing unit reproduces the audio scene synthesized by the audio scene-synthesizing unit.
