Abstract

A reception display apparatus for receiving data blocks repeatedly transmitted from a broadcasting station at regular intervals and displaying a screen image based on the received data blocks. Each of the data blocks including a data section. Data to be displayed as the screen image is divided into a plurality of data sections. The reception display apparatus comprises: a reception means for receiving the data blocks; a data judgment means for judging whether the data section in each received data block is normal; a storage means for storing every data section judged as normal by the data judgment means without storing data sections judged as abnormal; a condition judgment means for judging, before all data sections to be displayed as the screen image are stored in the storage means, whether a condition for displaying the screen image is satisfied; and a display means for displaying, when the condition judgment means judges that the condition is satisfied, a part of the screen image using data sections currently stored in the storage means.
