ABSTRACT:
A receiving apparatus and a power control method that permit standby power consumption to be reduced. If a Digital Signal Processor (DSP) stores an Entitlement Management Message (EMM), which is contained in a MPEG transport stream (MPEG TS) packet, in a memory, the DSP supplies a startup signal to a human interface (HI) microcomputer. According to the startup signal from the DSP, the HI microcomputer supplies power to a back-end portion to start up a main microcomputer, which causes the main microcomputer to initiate processing.
