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,...http://www.google.com/patents/US5862410?utm_source=gb-gplus-sharePatent US5862410 - System for controlling a variable source by the feedback of the running mode, and relevant circuit
