ABSTRACT:
Coefficient data in two coding blocks which overlap on a video screen are recorded in distant regions on a recording medium, the distant regions not being directly adjacent to one another. Error detected coefficient data during reproduction are corrected with reference to the feature that the overlapped pixels between the two coding blocks are equal.
