A first OS 200 is started, and start up of a second OS 300 is completed while a scramble key Ks is acquired and registered (step S201). The first OS 200 stores network settings information and program channel information (control information) in a state-storage buffer 103c (step S106), and the first OS 200 is shut down. The second OS 300 begins switch-to-SMP processing (step S204), and beings SMP processing (step S205). Thereafter, the control information is read from a state-storage buffer area 103a (step S206), and a first CPU 101a and a second CPU 101b share control of units of an AV decoder 101d (step S207). |
