<p>Bit stream data including digital image signals and character data are inputted to a decoder. Bit map type character data are extracted by a multiplexer (1) and supplied to a data decoder (7). The word detecting unit (20) of the data decoder (7) detects lines containing error data. A line processor (40) detects lines in which errors exist and stores the addresses of the delimiters of the lines before and after the lines in which errors exist in a register. In displaying the data while the lines in a buffer memory (22) are read and the data are decoded, an arbitrary line can be displayed a plurality of times by the random jump on the buffer memory (22) and specific lines can be skipped. Instead of reading the lines in which errors exist, the lines before and after the lines containing errors on the memory are accessed to interpolate the character data line by line. <IMAGE></p> |
