PCT No. PCT/JP97/01234 Sec. 371 Date Dec. 12, 1997 Sec. 102(e) Date Dec. 12, 1997 PCT Filed Apr. 10, 1997 PCT Pub. No. WO97/39578 PCT Pub. Date Oct. 23, 1997Bit stream data that contains a digital video signal and character data is input to a decoding apparatus. Bit map character data is extracted by a demultiplexer 1 and supplied to a data decoder 7. A word detecting portion 20 of the data decoder 7 detects a line that has error data. A line processor 40 detects a line that has error data and stores an address of the end of the line to a register. Thus, when data is displayed, while it is being read from a buffer memory 22 and decoded, the buffer memory is randomly accessed. Consequently, a particular line can be displayed a plurality of times. Alternatively, a particular line can be skipped. Instead of reading data of a line that has an error, by accessing lines that immediately precede or immediately follow the line that has the error in the memory, character data can be interpolated for each line.
