ABSTRACT:
A digital satellite broadcast receiver having a simultaneous multi-channel search function is disclosed, in which the currently broadcasting programs on the respective channels are displayed onto a plurality of divided windows respectively through one transponder, thereby providing a convenience to the channel search of the users. The number of the channels is detected by utilizing the program specific information (PSI) of the transport stream which is transmitted from a satellite. The screen is divided into as many as the number of the channels so as to set windows. Then the coding type of the picture header which is contained in the transport stream is read to detect the I picture. Then the I pictures of the relevant channels are displayed onto the respective divided windows. Then if the user selects one channel from among the displayed channels, then the selected picture is displayed in the original size.
