Data transfer rate control method and data transfer rate controller
 A data transfer rate control method inserts a stuff packet in real time to resolve the problem present in an ATM transmission for MPEG data. The method, for controlling a data transfer rate at which coded data are transferred in an asynchronous transfer mode may include the steps of: forming the coded data for an AAL layer (ATM Adaptation Layer); calculating an insertion timing for insertion of a NULL packet; inserting the NULL packet into the coded data of the AAL layer in consonance with the insertion timing, obtained by the calculation, for the NULL packet; and transferring, in the asynchronous transfer mode, the coded data of the AAL layer into which the NULL packet is inserted.
