In this case, the control unit 150 functions as a recording processing unit.

  Furthermore, the broadcast receiving apparatus 100 can dub (copy or move) a stream stored in another storage device to the storage 170. Furthermore, the broadcast receiving apparatus 100 can dubb the stream stored in the storage 170 to another storage apparatus.

  The power supply unit 180 controls power supply to each unit of the broadcast receiving apparatus 100. The power supply unit 180 receives power from a commercial power supply through a power plug, for example. The power supply unit 180 receives AC power from a commercial power source, converts the received AC power into DC, and supplies the DC power to each unit of the broadcast receiving apparatus 100.

  Further, the power supply unit 180 includes a power switch 181 for switching the power supply state of the broadcast receiving apparatus 100. As described above, the power switch 181 is provided on the broadcast receiving apparatus 100 so as to be operable from the outside. The power supply unit 180 switches the power supply state of the broadcast receiving apparatus 100 according to an operation signal from the power switch 181 or the remote controller 163.

  The power supply state of the broadcast receiving apparatus 100 includes a normal operation state, a standby state, a power supply OFF state, and the like. When the broadcast receiving apparatus 100 is in an operating state, the power supply unit 180 includes a signal processing system such as a tuner 111, a demodulation unit 112, and a signal processing unit 113 of the broadcast receiving apparatus 100, an audio processing unit 121, a speaker 122, and video processing. Power is supplied to output systems such as the unit 131, display processing unit 133, and display 134, and control systems such as the control unit 150.

In this case, the broadcast receiving apparatus 100 does not display video and reproduce audio. In this case, since power is not supplied to the light receiving unit 162, the broadcast receiving apparatus 100 cannot receive the operation signal transmitted from the remote controller 163. Therefore, for example, even when a power ON operation signal is input from the remote controller 163 in this state, the power is not turned ON.

  When the broadcast receiving apparatus 100 is in a standby state or a power-off state, the control unit 150 can execute a recording process by a function such as reserved recording. The control unit 150 can realize a reserved recording function by causing the CPU 151 to execute a program stored in the ROM 152 or the EEPROM 154. That is, the control unit 150 may start the recording process when receiving content corresponding to the reserved recording setting such as a preset time and channel, a preset broadcast code, or a preset keyword. it can. In this case, the control unit 150 functions as a reservation recording unit.

  For example, when recording processing is started from a standby state or a power-off state, the control unit 150 controls the power supply unit 180 to supply power to the signal processing system and the storage 170. Thereby, the control unit 150 can cause the broadcast receiving apparatus 100 to execute the recording process even in the standby state or the power-off state.

  Further, when the recording process is started from the power-off state, the control unit 150 controls the power supply unit 180 to supply power to the light receiving unit 162. Thereby, the control unit 150 can receive an operation signal from the remote controller 163.
