ABSTRACT:
A cell transfer method and a cell receiving apparatus in which cells of an asynchronous transfer mode are used to transfer information for a plurality of channels regardless of the number of channels and without reduction of the utilization rate of cell in the same cell configuration and the information for the channels can be reproduced while maintaining synchronization between the channels in a receiving side. The cell has an identifier for each channel and is exclusively used for each channel. Cells to be reproduced at the same time are given the same sequence number to be transferred. On the receiving side, when a cell is inputted in a cell disassembling circuit, the cell is disassembled into a sequence number, a channel identifier and channel data and channel information is written or stored in a buffer together with the sequence number by a distributing circuit in accordance with contents of the channel identifier. Reading of data from the buffers is made simultaneously from the buffers with respect to the data having the number indicated by a sequence number counter.
