A compression-coded high definition television signal is decoded and converted to a standard NTSC signal without loss of interlacing so that the resulting picture exhibits smooth motion. The compression-coding of the HDTV signal includes DCT processing to produce an 8.times.8 block of coefficient data. Upon decoding, the upper left quadrant of the coefficient data array is used to form a 4.times.4 subblock of coefficient data but the last row of elements of the subblock is replaced by corresponding elements of the eighth row of the 8.times.8 block of coefficient data.
