  At 18:00, as the operation a611, the server unit power ON 311 is processed by the reservation management unit 132f or SW_S123, and the server state time chart 601 should be changed from “OFF” to “ON”. However, first, the server function unit 150 is activated (S901), and the server a function unit 150 is requested to be activated by the operation a611.

Further, a process of continuing the operation of the server function unit 150 (S902) is performed, and the process proceeds to a process of selecting a process MODE (S903).
When MODEa is selected in the process (S903) for selecting the process MODE, a process (S904) for confirming whether the television unit is operating is performed. At this time, the television state time chart 602 is “OFF”. Therefore, in the process of confirming whether the television unit is operating (S904), it is determined that the television unit is not operating (No in S904), and the presence of the client device connected to the network is confirmed by the client confirming unit 132c. A confirmation process (S905) is performed. If MODEb is selected in the process (S903) for selecting the process MODE, a process (S905) for confirming the existence of a client device connected to the network is performed.

  In other words, in the process of selecting the process MODE (S903), regardless of which MODE is selected, if the TV state time chart 602 is “OFF”, the process of confirming the existence of the client device connected to the network (S905). ) Is performed.

  At this time, since the client state time chart 603 is “OFF”, it is determined that the client apparatus does not exist (No in S905) in the process of confirming the existence of the client apparatus connected to the network (S905), and the server A signal for changing the power output from the power supply unit 120 from “ON” to “OFF” is output from the power control unit 132e, and the server function unit 150 is stopped (S906). In other words, this processing is the processing of the server unit power OFF 312 in FIG.

  Further, a process for determining whether or not the server operation function unit 150 is requested to start (S907) is performed, but as described above, the start is requested (Yes in S907). In the fifth embodiment, after the above process is performed, a predetermined time such as 3 minutes is measured by the timer means 132d, and the server function unit 150 is activated after the measured predetermined time has elapsed. The processing of the server unit power ON 311 that is the processing to be performed (S901) is performed. Thereafter, the plurality of processes described above are repeated.

  That is, the server function unit 150 is stopped for a period of time from the process of determining whether the server operation function unit 150 is requested to start (S907) to the process of restarting the server function unit 150 (S901). Therefore, at this time, the server state time chart 601 is in the “OFF” state, and therefore the apparatus state time chart 604 is also in the power OFF 301 state at that time.

  Next, at 19:00, as operation b612, the client apparatus starts and starts operating, and the client state time chart 603 is changed from “OFF” to “ON”. Further, a process (S901) for starting the server function unit 150, a process for continuing the operation of the server function unit 150 (S902), a process for selecting a process MODE (S903), which are performed after 18:00, When MODEa is selected, the process of confirming whether the television unit is operating (S904) and the process of confirming the presence of the client device connected to the network (S905) are continuously performed.

  At this time, since the television state time chart 602 is still “OFF”, the television unit is in operation regardless of which MODE of MODEa and MODEb is selected in the processing MODE selection processing (S903). In the process of confirming (S904), it is determined that the television unit is not in operation (No in S904), and the process of confirming the existence of the client device connected to the network (S905) is performed.

  Furthermore, since the client state time chart 603 is “ON” at this time, it is determined that the client device exists (Yes in S905) in the process of confirming the presence of the client device connected to the network (S905), and the server The processing shifts to processing (S902) for continuing the operation of the function unit 150. Thereafter, the plurality of processes are repeated.

  Accordingly, since the server function unit 150 continues to operate, the server state time chart 601 changes from “OFF” to “ON”, and the apparatus state time chart 604 changes from the power OFF 301 to the standby 302 state.

  Next, at 20:00, as the operation c613, the TV section power ON 315 is processed by SW_T124, and the television state time chart 602 is changed from “OFF” to “ON”. Further, after 19:00, the processing for continuing the operation of the server function unit 150 (S902), the processing for selecting the processing MODE (S903), and if MODEa is selected, confirms whether the television unit is operating.

The television unit is determined to be operating (Yes in S904), and the process proceeds to the process of continuing the operation of the server function unit 150 (S902).

That is, when MODEa is selected, the process for confirming the existence of a client device connected to the network (S905) is not performed thereafter.
In addition, when MODEb is selected in the process MODE selection process (S903), the server function unit 150 continues to operate (S902), the process MODE selection process (S903), and connected to the network. The processing for confirming the existence of the client device (S905) is performed. At this time, since the client state time chart 603 is “ON”, the processing for confirming the existence of the client device connected to the network (S905). In step S905, it is determined that the client device exists (Yes in step S905), and the process proceeds to processing (S902) for continuing the operation of the server function unit 150.

  In other words, when MODEb is selected, the processing for continuing the operation of the server function unit 150 (S902), the processing for selecting the processing MODE (S903), and the presence of the client device connected to the network are thereafter performed. The confirmation process (S905) is performed.

  That is, only when MODEb is selected, the process of confirming the existence of a client device connected to the network is performed (S905). The server function unit 150 operates regardless of either MODEa or MODEb. The process of continuing (S902) is performed.

  That is, in the fifth embodiment, when MODEa is selected, the TV unit is operating, so the server function unit 150 continues to operate, and when MODEb is selected, there is a client device. Therefore, the server function unit 150 continues to operate.

  Accordingly, the server state time chart 601 continues to be in the “ON” state, and the apparatus state time chart 604 transitions from the standby 302 to the power ON 303 state. Thereafter, the plurality of processes described above are performed, and the respective states are continued.
