ABSTRACT:
A digital TV and a method of switching a channel automatically thereof provides a viewer with advance notice of an automatic channel switch using linkage descriptor information on HD broadcasting. Providing the viewer with notice of the switched channel reduces viewer confusion. The method includes the steps of determining whether a linkage descriptor is included in additional information regarding a broadcast program whether the broadcast program regardless of whether the broadcast program is selected by a viewer, checking the remaining time of the broadcast program if the linkage descriptor is included in the additional information, displaying a channel switch notice message on a screen, determining whether or not the broadcast program has ended, switching a channel of the broadcast program to a designated channel when the broadcast program ends, and displaying a channel switch confirmation message on the screen.
