  When the recording end time comes (Yes in step S68), the control unit 120 instructs the command processing unit 130 to transmit a CEC command for ending the recording. The command processing unit 130 issues a CEC command <Record Off> for ending recording, and transmits it to the recorder 20 via the CEC • I / F 164 (step S69).

  When the reserved recording ends, the control unit 120 determines whether or not there is a user sensed by the human sensor 13 in order to determine whether or not the recorder 20 is used by the user. To instruct. The determination unit 170 compares the value of the human detection signal acquired from the human detection sensor 13 with a predetermined threshold value recorded in the recording unit 110. That is, the determination unit 170 determines whether or not the temperature change around the human sensor 13 (that is, the temperature change around the television 10) is larger than the reference temperature change (step S70).

  When determination unit 170 determines that the temperature change around human sensor 13 is greater than the reference temperature change (Yes in step S70), determination unit 170 determines that the user is within the detection range of human sensor 13. Recognize and notify the control unit 120 of this.

  The control unit 120 instructs the display processing unit 150 to display a dialog for inquiring whether or not to put the recorder 20 in the standby state on the display unit 11. The display processing unit 150 displays a dialog for inquiring whether or not to put the recorder 20 in the standby state on the display unit 11 in accordance with an instruction from the control unit 120 (step S71).

  In the dialog displayed on the display unit 11, for example, options “Yes” and “No” are displayed together with a message “Would you like to put the recorder in a standby state or is the recorder in use?”. The control unit 120 determines whether to enter the standby state according to an instruction from the user by selecting “Yes” or “No” by operating the remote controller 30 (step S72). Note that the messages and options displayed in the dialog are not limited to this.

  If an instruction not to put recorder 20 in the standby state is acquired (NO in step S72), this operation is terminated. When an instruction to set the recorder 20 to the standby state is acquired (Yes in step S72), or when the determination unit 170 determines that the temperature change around the human sensor 13 is smaller than the reference temperature change ( In step S70, No), the control unit 120 instructs the command processing unit 130 to transmit a CEC command for setting the recorder 20 in the standby state. The command processing unit 130 issues a <Standby> command for setting the recorder 20 in the standby state, and transmits the command to the recorder 20 via the CEC / I / F 164 (step S73).

  Also, the flow of execution of the reserved recording in the recorder 20 is the same as that in FIG.

  As described above, when the reserved recording ends, the control device 100 ′ determines whether or not there is a user around the television 10 ′. If there is no user, the control device 100 ′ can put the recorder 20 in a standby state.

  Thereby, if there is a user around the television 10 ′, the television 10 ′ can determine that the user is using the recorder 20, and if there is no user around the television 10 ′, the user uses the recorder 20. It can be determined that it is not. When the television 10 ′ determines that the user is not using the recorder 20, the recorder 20 can be automatically put into a standby state, so that the power consumption of the recorder 20 can be reduced.
