In a method for admitting a new data file into a channel, a request for admission of the new data file into the channel is received. It is determined as to whether at least a minimum number of bits of at least one current data file has been transferred to the receiver. The rate at which the at least one current data file is transferred is reduced below a minimum constant bit rate in response to a determination that at least a minimum number of bits of the at least one current data file has been transferred to the receiver and the new data file is admitted into the channel.
