PROBLEM TO BE SOLVED: To perform scalable transmission by effectively utilizing technologies being spread widely in existing video services.;SOLUTION: A scalable transmission/reception system AA includes a scalable transmission device 1 and a scalable reception device 2. The scalable transmission device 1 uses a single stream encoding method to generate an upper layer multiplexed signal SIG2 and a lower layer multiplexed signal SIG3 from an input video image SIG1 and outputs the generated signals. The scalable reception device 2 uses a single stream decoding method to generate an upper layer output video image SIG4 and a lower layer output video image SIG5 from the upper layer multiplexed signal SIG2 and the lower layer multiplexed signal SIG3 and outputs the generated video images.;COPYRIGHT: (C)2015,JPO&INPIT
