Abstract

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.

A digital broadcast receiving apparatus for selectively receiving a desired channel based on a user instruction from a plurality of channels included in airwaves, comprising:

a tuning unit for extracting from said airwaves first image coded data that corresponds to said desired channel;
a data storage unit for storing second image coded data corresponding to a prescribed picture, the prescribed picture being stored in the data storage unit prior to operation of the digital broadcast receiving apparatus;
a control unit for determining whether it is possible or impossible to generate an image signal based on said first image coded data;
and
an image data decoding unit for decoding said second image coded data from said data storage unit to generate an image signal for displaying said prescribed picture in response to said control unit determining that generating an image signal based on said first image coded data is impossible.
