Abstract: A reception apparatus and reception method receive sub streaming concurrently with receiving main streaming. A streaming apparatus transmits sub streaming concurrently with transmitting main streaming. An operating room system includes cameras that acquire image data and an audiovisual controller that receives sub streaming from the cameras concurrently with receiving main streaming from one of the cameras. A vehicle control system includes cameras mounted onto a vehicle and an integrated unit that receives sub streaming from the cameras concurrently with receiving main streaming from one of the cameras.

Abstract: Disclosed herein is an audio signal encoding method for dividing an audio signal into a plurality of subband signals, allocating bits to the subband signals on a basis of psychoacoustic analysis, and encoding the audio signal, in which the audio signal encoding method may include an evaluation criterion calculating step, a sorting step and a repetitive process step.

Abstract: A method and apparatus for magnetohydrodynamic (MHD) generation of a combined-closed-cycle type using an MHD generator and a gas turbine-generator unit. A heater heats ooperative fluid to introduce the heated operative fluid into an MHD generator for power generation. The operative fluid is passed from the MHD generator to a compressor through a first portion of a heat exchanger. The compressed operative fluid is introduced from the compressor to a gas tubine-generator unit through a second portion of the heat exchanger, so that the gas turbine-generator unit generates power by the compressed operative fluid. The heat exchanger recovers heat energy of the operative fluid between the first and second portions thereof. After power generation, the operative fluid is returned to the heater form the turbine-generator unit to complete a combined-closed-cycle of the operative fluid.
