  FIG. 3 is a flowchart showing a flow of a power-off timer process for performing power-off according to time and power-off according to program information of a broadcast signal in the first embodiment of the present invention. The following description is based on the order of steps shown in the flowchart of FIG.

  The power-off timer process for setting the power-off timer according to the time and broadcast signal program information and turning off the power is started by the microcomputer 17 when the broadcast receiver is turned on and the user operates the power-off timer from the remote controller 4. The processing is sequentially performed by the microcomputer 17.

  When the off timer button 42 in FIG. 2 of the remote controller 4 is operated, the remote controller light receiving unit 20 receives the signal and notifies the microcomputer 17 of the signal. When the microcomputer 17 determines that the operation is a power-off timer, the microcomputer 17 instructs the OSD processing unit 16 to display the power-off type selection screen shown in FIG. 4, and the OSD processing unit 16 displays the power-off type selection screen on the TV monitor 3. (Step A1).

  The user checks which type of power-off is selected from the power-off type selection screen, and if it is selected, performs the process of step A7 for determining the power-off time of the selected setting type. The process of step A3 is performed to check whether the off setting button 43 for turning off the power at the end time of the program being viewed has been operated (step A2).

  It is checked whether the light receiving unit 20 receives the signal of the off setting button 43 shown in FIG. 2 for turning off the power at the end time of the program currently being viewed. When the off setting button 43 is operated, the process of step A5 for setting the power off setting type is performed, and when the off setting button 43 is not operated, the process of step A4 for waiting for a predetermined time is performed (step A3). .

  If there is no operation of the off setting button 43 of the remote controller 4, the process returns to step A2 for checking whether a setting type is selected again after waiting for a predetermined time (step A4).

  When there is an operation of the off setting button 43 of the remote controller 4, 2 is set as a setting type for turning off the power at the end time of the currently viewed program and stored in the memory (step A5).

  The end time of the currently viewed program is extracted from the TS packet program information extracted by the TS decoder 12, stored in the memory as the power-off time, and the process proceeds to step A11 (step A6).

  In step A7, the power-off setting type selected by the user from the power-off type selection screen is input from the OSD processing unit. The input setting type is checked and divided into processes for determining the power-off time of each setting type (step A7). As a result of checking the setting type, if the setting type is 1, the process of step A8 for determining the power-off time of setting type 1 is performed. If the setting type is 2, the process of determining the power-off time of setting type 2 is determined. If the setting type is 3, the process of step A10 for determining the power-off time of the setting type 3 is performed (step A7).

  Since the setting type 1 is a setting type in which the power is turned off when the power-off time selected from the current time has elapsed, the power-off time selected by the user shown in FIG. 4 is input from the OSD processing unit (step A8). . The power-off time is obtained from the input power-off time and the current time, stored in the memory as the power-off time, and the process proceeds to step A11 (step A8).

  Since the setting type 2 is a setting type in which the power is turned off at the end time of the currently viewed program, the end time of the currently viewed program is extracted from the program information of the TS packet extracted by the TS decoder 12, and the power is turned off. The time is stored in the memory, and the process proceeds to Step A11 (Step A9).

  Since the setting type 3 is a setting type in which the power is turned off at the end time of the program being viewed when the power-off time selected from the current time has elapsed, the power-off time selected by the user shown in FIG. Input from the processing unit (step A8). The power-off time is obtained from the input power-off time and the current time, and the program end time viewed at the power-off time is the power-off time. However, since the program end time cannot be obtained until the power-off time obtained from the power-off time and the current time, the power-off time obtained as a temporary power-off time is stored in the memory, and the process proceeds to step A11 (step A10). .

  The power-off time determined in step A8, step A9, and step A10 is taken out of the memory and compared with the current time. As a result of comparison, if the current time is equal to or greater than the power-off time (the current time has become the power-off time), the process of step A13 for checking whether the setting type is 3 is performed. When the time is smaller than the off time (the current time has not passed the power off time), the process of step A12 is performed to wait for a certain time (step A11).

  When the current time is smaller than the power-off time, after waiting for a fixed time, the process returns to step A11 to check again whether the current time is equal to or greater than the power-off time (step A12).

  When the current time is larger than the power-off time, it is further checked whether the setting type is 3. If the setting type is 3, the process of step A15 is performed to change the power-off time temporarily determined in step A10 to the end time of the currently viewed program. If the setting type is other than 3, the power is turned off. The process of step A14 to be performed is performed (step A13).

  If the setting type is other than 3, the power control unit 22 is notified of powering off the broadcast receiving device 1 (step A14). The power supply control unit 22 that has received the notification turns off the power supply 21, and the process ends (step A <b> 14).

  If the setting type is 3, the power is turned off at the program end time of the program being viewed when the power-off time selected from the current time has elapsed. Since the power-off time selected from the current time has already passed in the check in step A11, the end time of the program currently being viewed is extracted from the program information of the TS packet extracted by the TS decoder 12, and is set as the power-off time. Store in the memory (step A15).

The power-off time determined in step A15 is taken out of the memory and compared with the current time. As a result of the comparison, when the current time is equal to or greater than the power-off time, the process of step A18 is performed to turn off the power. When the current time is smaller than the power-off time, the process of step A17 to wait for a certain time is performed ( Step A16).

  When the current time is smaller than the power-off time, after waiting for a fixed time, the process returns to step A16 to check again whether the current time is equal to or greater than the power-off time (step A17).

  When the current time is greater than the power-off time, the power control unit 22 is notified of power-off of the broadcast receiving device 1 (step A18). The power supply control unit 22 that has received the notification turns off the power supply 21, and the process ends (step A 18).

  According to the first embodiment, it is possible to provide a user-friendly power-off timer by setting the power-off timer based on time and the power-off timer based on broadcast signal program information in combination. Thus, it is possible to provide a broadcast receiving apparatus and a power-off method in the broadcast receiving apparatus that can improve the energy saving effect by forgetting to turn off the power of the broadcast receiving apparatus by using a more convenient power off timer by the user. it can.

  In the first embodiment, when the program end time of the program that the user is viewing is set as the power-off time, and the program that the user is viewing before the power-off time elapses is changed. FIG. 5 shows another example of the first embodiment in which the power-off time can be changed to the end time of the program that the user is viewing. In FIG. 5, after step A12 shown in FIG. 4 of the first embodiment, step A12 * 1 for checking whether the setting type is 2, and if the setting type is 2, the end time of the currently viewed program is displayed. Step A12 * 2 is extracted from the program information of the TS packet extracted by the TS decoder 12 and set as the power-off time. Further, in FIG. 5, after step A17 shown in FIG. 4 of the first embodiment, a process of step A17 * for changing the power-off time to the end time of the currently viewed program is added. By adding a step in this way, even when the user is changing the program that the user is viewing before the initially determined power-off time elapses, the power can be turned off at the end time of the changed program. .

(Second Embodiment)

The no-operation power-off timer processing for setting the power-off timer based on the no-operation time and the program information of the broadcast signal to turn off the power sets the no-operation time from the no-operation time setting screen displayed on the TV monitor 3 until the user turns off the power. Then, processing is started from the microcomputer 17 and processing is sequentially performed by the microcomputer 17. The no-operation time setting screen for setting the no-operation time displays the menu screen on the TV monitor 3 when the broadcast receiver is turned on and the user operates the menu button 44 of FIG. 4 are displayed on the TV monitor 3 by operating the cursor movement buttons 46a, 46b, 46c, 46d and the determination button 47 in FIG.

  FIG. 6 is a flowchart showing the flow of the no-operation power-off timer process after the no-operation time is counted by the no-operation time counter that counts the no-operation time in the second embodiment of the present invention. The following description is based on the order of steps shown in the flowchart of FIG.

  It is checked whether the time counted by the no-operation time counter has passed the no-operation time set by the user (step B1). As a result of the check, if the no-operation time set by the user has not elapsed, the process of step B2 for waiting for a fixed time is performed, and if it has elapsed, the no-operation power-off type selection screen shown in FIG. 7 is displayed. Step B3 is performed (Step B1).

  If the time counted by the no-operation time counter has not exceeded the no-operation time set by the user, the process returns to step B1 for checking whether the no-operation time has passed again after waiting for a fixed time ( Step B2).

  When the time counted by the no-operation time counter exceeds the no-operation time set by the user, the OSD processing unit 16 is instructed to display the no-operation power-off type selection screen, and the OSD processing unit 16 Displays a no-operation power-off type selection screen on the TV monitor 3 (step B3).

  Since the setting type 2 is a setting type in which the power is turned off at the end time of the currently viewed program, the end time of the currently viewed program is extracted from the program information of the TS packet extracted by the TS decoder 12, and the power is turned off. The time is stored in the memory 18 (step B10).

  The power-off time determined in step B10 is taken out of the memory and compared with the current time. As a result of comparison, when the current time is equal to or greater than the power-off time (the current time has become the power-off time), the process of step B13 for turning off the power is performed, and the current time is smaller than the power-off time (current When the time has not passed the power-off time), the process of step B12 is performed to wait for a certain time (step B11).

  When the current time is smaller than the power-off time, after waiting for a fixed time, the process returns to step B11 for checking again whether the current time is equal to or greater than the power-off time (step B12).

  When the current time is greater than the power-off time, the power control unit 22 is notified of powering off the broadcast receiving device 1 (step B13). Receiving the notification, the power supply control unit 22 turns off the power supply 21, and this process ends (step B <b> 13).

  According to the second embodiment, it is possible to provide a user-friendly power-off timer by combining and setting the power-off timer based on the no-operation time and the power-off timer based on the broadcast signal program information. Thus, it is possible to provide a broadcast receiving apparatus and a power-off method in the broadcast receiving apparatus that can improve the energy saving effect by forgetting to turn off the power of the broadcast receiving apparatus by using a more convenient power off timer by the user. it can.
