<p>PURPOSE: To change a data length and to perform data reproduction without causing instantaneous interruption or the like by informing a reception side about the change information of the data length in the transmission of a fixed length packet. CONSTITUTION: Original data 11 are continued at the data length A21, decomposed into packets, multiplexed and transmitted to the reception side. A pointer 13 constituted of offset information 19 and an offset 20 sets the boundary position of the head of the original data 11. On the reception side, by recognizing the boundary position of the original data 11, the original data 11 can be reproduced. When the data length A21 of the original data 11 is increased to (the data length A21 + the data length B22), by the offset information 19 and the offset 20 in the area of the pointer 13 for indicating the boundary position of the data, the reception side is informed of information how the data length. Changed. Thus, the change of the data length of the original data 11 is recognized by a change point on the reception side and the original data 11 are reproduced without causing the instantaneous interruption of communication data.</p> |
