Abstract
A system for controlling the rate of flow of data generated by a variable rate data source and fed to a buffer which outputs the data at a constant bit rate. The operating mode, which sets the bit rate of the variable rate data source, is determined not only by the degree to which the buffer is filled, but also by the immediately preceding operating mode. The feedback of the operating mode results in an hysteresis effect on the mode, thus reducing the number of changes of the rate of data generation and thereby increasing the transmission quality of the data generated and output from the system.
