The digital broadcast receiving apparatus according to the present invention
includes a tuning unit for outputting normal image data for performing a normal
reproduction operation corresponding to a user selected channel, a memory unit
for outputting background image data for performing a background reproduction operation
when the normal reproduction operation cannot be performed, a data selector for
receiving the normal image data and the background image data and outputting one
of the normal image data and the background image data, and an MPEG video decode
unit for decoding image data output by the data selector to generate an image signal.
The tuning unit successively receives the respective channel selected in the background
independently of the user selection, and stores the background image data corresponding
to the respective channels in the memory unit.
