A high-efficient heat cycle device formed by combining a heat engine with a refrigerating machine, wherein steam generated in a boiler is cooled by a condenser after driving turbine, built up by a pump, and circulated into the boiler in the form of high-pressure condensate. Depending upon the technology available, the location information may be supplied in-band or on a parallel datapath. In addition, one or more playback controls are configured to control the stream during simulation.
