Abstract
A digital broadcast receiving apparatus receives a digital broadcast signal, which consists of layers each obtained by dividing a transmission bandwidth into a plurality of segments and combining some of the segments, and outputs images and/or sound from one of the layers constituting the received digital signal. This apparatus is characterized by comprising broadcasting format retention means (channel to broadcasting format correspondence table database) for retaining the broadcasting format, for each layer, of each broadcast station and switching means (layer switching means) for switching the output layer based on the broadcasting format, for each layer, of each broadcast station retained in the broadcasting retention means. Thus, this apparatus can output images and sound without interruption.
