Data transmission/reception apparatus according to the present invention MPEG-2 based transmits/receives input data including; at least MPEG-2 based video data and audio data in a low bit rate and in a low error occurrence rate. The data transmission apparatus is comprised of: a division circuit (30) which separates the input data into video, audio, and user data; FIFO circuits (31 to 33); a combination circuit (35); a PES private data attachment circuit 36; a PTS generation/attachment circuit (37); a PES header attachment circuit (39); and a transport header attachment circuit (40). On the other hand, the data reception apparatus is comprised of: a transport header separation circuit (51); a PES header separation circuit (52); a PTS detection circuit (53); a PES private data separation circuit, a distribution circuit (55); FIFO circuits (56 to 58); a FIFO control circuit; and a combination circuit (60).
