<p>A cell transfer apparatus and method using a variable rate codec wherein a sequence number of each cell is determined by adding a weight corresponding to an encoding time of information. In a transmitting side (101, 102, 103, 104, 105) each of encoded pieces of information is cellulated to a predetermined length cell for each information having a length of integer times a predetermined unit length of information. A sequence number of a next cell is determined by adding as a weight the number of pieces of information having a unit length included in the last cell to a sequence number of a last cell, and is sent as being added to each cell. In a receiving side (105, 106, 107) reproduction timing numbers comprising serial numbers are sequentially generated at timings synchronous with the unit length of the pieces of information and compared with the sequence number added to each cell. When the both coincide, the information of that cell is decoded.</p> |
