Abstract: In a sampled data transmitting apparatus in which the sampled data to be transmitted are divided into odd-numbered samples and even-numbered samples and arranged in different rows of a two-dimensional data array, and in which error correction codes are annexed to each row and to each column of the two-dimensional data array, the row arraying sequence in one of the odd-numbered or even-numbered rows is caused to differ from the row arraying sequence in the other of the odd-numbered or even-numbered rows so that odd-numbered data and even-numbered data continuous with the odd-numbered data are not arranged in one row. In this manner, even when error correction becomes impossible by the error correcting code for one row, interpolation remains feasible because there exist no odd-numbered data or even-numbered data contiguous to each other in the row.
