A stream transmitting section outputs encoded stream data. A division instructing section generates dividing point information that designates a dividing point of the encoded stream data. A parallel stream transmitting section divides stream data that is output by the stream transmitting section and side information necessary for decoding from halfway along the stream that is extracted based on the stream data into a predetermined number of parts at dividing points designated by the dividing point information, performs parallelization thereof, and transmits data obtained as a result thereof to a stream decoding section on a receiving side.
