Abstract
Disclosed is a method for transmitting and receiving audio in a Mosaic electronic program guide (EPG) service. A digital broadcast transmitting side mixes stereo audio signals corresponding to each sub-picture within a Mosaic EPG picture and encodes mono audio signals corresponding to odd and even-numbered sub-pictures into one stereo audio signal. The digital broadcast transmitting side transmits the stereo audio signal based on a result of the encoding through the Mosaic EPG service. Therefore, the method can efficiently transmit audio of a sub-picture within the Mosaic EPG picture, and can minimize bandwidth necessary for transmitting audio of sub-pictures within the Mosaic EPG picture. A user can confirm and select a desired broadcast program while listening to audio corresponding to a sub-picture within the Mosaic EPG picture, thereby conveniently using the desired broadcast program.
