Description

  The present invention relates to a content reproduction apparatus such as a television receiver, a power supply control method thereof, a program for the content reproduction apparatus, and a computer-readable recording medium.

  In recent years, there are an increasing number of electronic devices surrounding us. For example, a printing machine, an imaging machine, a recording / reproducing apparatus, a personal computer, a television receiver, or the like. Most of these electronic devices generally control power on / off by operating a power key (button) to supply power to the device or stopping power supply. Is. Therefore, in order to turn off the power of the electronic device after use, it is necessary to turn off the power and turn off the electronic device every time. Therefore, the on state continues until the power of the electronic device is turned off even when the user is absent. That is, if the power is not turned off after using the electronic device due to the carelessness of the user, unnecessary power consumption may be caused, and further, the electronic device may be damaged due to heat generated by long-time driving. In particular, in recent video display devices such as television receivers (TV receivers), there is a tendency for circuits to become complicated and large-scale in order to cope with new technologies such as digital broadcasting. Therefore, a large amount of electric power is required to drive such an electronic device, and a large amount of heat is generated.

  Therefore, in order to solve such a problem, Patent Document 1 discloses a technique for automatically turning off the power of the TV receiver. Specifically, when a user leaves his / her seat without turning off the power while watching TV, the power is automatically turned off and the operation standby mode is switched after a predetermined time has passed. The TV receiver disclosed in this document is equipped with an infrared sensor that senses far-infrared rays emitted from the human body, and a certain time has elapsed since the sensor last sensed far-infrared rays emitted from the human body. After the time has passed, the TV receiver is automatically turned off. According to this, it is not necessary to turn off the power of the TV receiver one by one, it is possible to prevent unnecessary power consumption and prevent damage to equipment due to heating.

JP 6-78246 A (published March 18, 1994)

  However, in the TV receiver disclosed in Patent Document 1, since the power is automatically turned off, the power supply to all the circuits of the TV receiver is stopped, or at least the remote control light receiving unit or the like is Power is supplied to only a limited number of circuits. Therefore, when the power of the TV receiver is turned on again, it is necessary to supply power to the various circuits of the TV receiver and start each of the various circuits. Such an electronic device has a problem that it takes time until the user can use the device after the power is turned on.

  In particular, as described above, recent TV receivers tend to be complicated and large in scale. For example, in a TV receiver, it is necessary to acquire additional information such as electronic program guide (EPG: Electronic Program Guide) data, or to perform demodulation processing of a digital broadcast. From the power supply until the screen of the TV receiver is displayed. Takes a long time and the time lag is large.

  As described above, it takes time to start up an electronic device such as a TV receiver, and there is a case where the user may wait for a while until the user can actually use the device. Therefore, if the user wants to use the electronic device immediately, dissatisfaction occurs.

  Therefore, the present invention has been made in view of the above problems, and the purpose of the present invention is to start up in less time if the viewer turns on the power even when the power is turned off. It is an object of the present invention to provide a content reproducing apparatus, a power control method thereof, a program for the content reproducing apparatus, and a computer-readable recording medium.

In order to solve the above problems, a content reproduction apparatus according to the present invention includes a power supply unit that supplies power, a processing unit that processes content, and an output unit that outputs the content processed by the processing unit. A playback device that detects the presence of a viewer,
When the human power sensor detects a viewer when the power supply unit stops supplying power to the processing unit and the output unit, the power supply unit is controlled to supply power to the processing unit. And a power supply control unit.

  According to the above configuration, when the human sensor detects a viewer in a state where power is not supplied to the processing unit and the output unit, power is supplied to the processing unit. The state where power is not supplied to the processing unit and the output unit is a state where the power of the content reproduction apparatus is turned off. Therefore, according to the present invention, when the human sensor detects a viewer in a state where the power of the content reproduction apparatus is turned off, power is supplied to the processing unit. That is, power is supplied to the processing unit while power supply to the output unit is stopped. In this state, when the viewer turns on the power of the content reproduction apparatus, it is only necessary to supply power to the output unit, and thus the time required to completely start the content reproduction apparatus is very short.

  In the conventional content reproduction apparatus, after the power is turned off once, when the viewer turns on the power, the start process is started from the state where the power supply to the processing unit is also stopped. Since the said process part contains many members, in order to start, much electric power is required, and that starting will take time. Therefore, if the power supply to the processing unit is started from a state in which it is stopped, it takes time until the content playback apparatus is completely started, and the viewer waits for a while.

  On the other hand, in the content playback apparatus of the present invention, when the viewer turns on the power after the power is turned off, the content playback apparatus starts immediately, so that the content playback apparatus does not wait for actual viewing. Absent. That is, when the viewer wants to view the content playback device immediately, the viewer can view the content playback device without dissatisfaction.

  The content playback apparatus according to the present invention further includes an optical sensor that detects ambient brightness, and when the power supply unit stops supplying power to the processing unit and the output unit, When the brightness detected by the light sensor exceeds a predetermined standard, the power control unit controls the power supply unit to supply power to the human sensor, and the light sensor detects When the brightness does not exceed a predetermined standard, the power supply control unit controls the power supply unit so as to stop the supply of power to the human sensor.

  According to the above configuration, the optical sensor that detects the brightness around the content reproduction apparatus is provided. If the brightness detected by the optical sensor exceeds a predetermined standard, that is, if the surroundings are bright, the viewer is likely to use the content reproduction apparatus. Therefore, when the light sensor determines that the surroundings are bright while the power supply to the processing unit and the output unit is stopped, power is supplied to the human sensor. Thus, when the human sensor detects the viewer, power is supplied to the processing unit, and when the viewer turns on the power of the content reproduction apparatus, the processing unit can be started immediately.

Conversely, if the brightness detected by the light sensor does not exceed a predetermined standard, that is, if the surroundings are dark, the viewer is unlikely to use the content reproduction device. Therefore, when the optical sensor determines that the surroundings are dark while the power supply to the processing unit and the output unit is stopped, no power is supplied to the human sensor. As a result, since the motion sensor does not operate, it is possible to prevent the motion sensor from being erroneously detected as a viewer and supplying power to the processing unit. Therefore, wasteful power supply to the processing unit can be suppressed, so that power consumption can be reduced.
As described above, the content reproduction apparatus according to the present invention can further improve the accuracy of the human sensor by further including the optical sensor.

  The content playback apparatus according to the present invention further includes a timer for measuring an elapsed time from the time when the presence sensor last detected the presence of the viewer, and the power control unit is measured by the timer. When the elapsed time reaches a predetermined time, it is preferable to control the power supply unit so that the supply of power to the processing unit is stopped.

  According to the above configuration, the power supply to the processing unit stops when a predetermined time elapses from the time when the human sensor detects the presence of the viewer last time. Therefore, even if power is supplied to the processing unit, if the viewer leaves the seat for a while and the state where the human sensor does not detect the viewer continues, the power to the processing unit is automatically Stop supplying.

  That is, according to the present invention, the power supply to the processing unit automatically stops when the viewer leaves the vicinity of the content reproduction apparatus for a while, such as by removing his / her seat. Thereafter, when the viewer returns to the vicinity of the content reproduction device, the power supply to the processing unit is automatically started. As described above, the content reproduction apparatus according to the present invention detects whether or not there are viewers in the vicinity, and appropriately supplies power to the processing unit accordingly. According to this, since the power supply to the processing unit is stopped when the viewer is away from the vicinity of the content reproduction apparatus, it is possible to prevent wasteful power consumption.

  Moreover, in the content reproduction apparatus according to the present invention, the human sensor includes an optical sensor that detects ambient brightness, an image sensor that images an object, a heat sensor that measures heat, a sound sensor that detects sound, It is preferable to include at least one sensor among a vibration sensor that detects vibration and a temperature sensor that measures temperature.

  According to the above configuration, the human sensor and the image sensor can detect the viewer with high accuracy.

  In the content reproduction apparatus according to the present invention, the processing unit includes a receiving unit that receives a broadcast signal, and a generation unit that processes the broadcast signal received by the receiving unit and generates a program. Is preferred.

  According to the above configuration, it is possible to obtain a television receiver that can be started up and viewed immediately after the power is turned off.

  Further, in the power control method for the content reproduction apparatus according to the present invention, in order to solve the above-described problem, a power supply unit that supplies power, a processing unit that processes content, and a content processed by the processing unit are output. A power supply control method for a content reproduction apparatus including an output unit and a human sensor for detecting the presence of a viewer, wherein the power supply unit stops supplying power to the processing unit and the output unit When the presence sensor detects the presence of a viewer, the power supply unit may be controlled to supply power to the processing unit.

  According to the above method, when the viewer wants to view the content reproduction apparatus immediately, it can be viewed immediately without dissatisfaction. In addition, the power consumed when the power is turned off can be kept low.

  The above-described content playback apparatus may be realized by a computer. In this case, a program for causing the content playback apparatus to be realized by the computer by causing the computer to operate as each unit, and a computer reading that records the program Possible recording media also fall within the scope of the present invention.

  The content playback apparatus of the present invention has an effect that even if the power is turned off once, it can be started up in less time if the viewer turns on the power.

The power supply unit 40 is supplied with electric power from the outside through an outlet or the like.

(Configuration of sub-microcomputer 39)
The sub-microcomputer 39 controls which member the power supply unit 40 supplies power to. The sub-microcomputer 39 controls the power supply unit 40 to (1) complete standby mode in which power supply to members other than the sub-microcomputer 39 and the remote control light-receiving unit 35 is stopped, and (2) power supply to the output unit 47. Three modes, a quick start mode for stopping the power supply, (3) a standby mode for stopping the supply of power to the processing unit 46 and the output unit 47, and an auto quick start mode for switching the quick start mode as appropriate. Yes.

  Note that the above three modes are modes in a standby state (a state where power is supplied to some members) when the power of the TV receiver 10 is turned off. This is a state in which power is supplied to some of the members and the apparatus is waiting for the next time the TV receiver 10 is turned on. Therefore, the power supply to all the members of the TV receiver 10 is stopped, and the power supply unit 40 is in a pause state in which power is supplied from the outside (the power supply from the power supply unit 40 to other members is stopped). It is also possible to make a state). However, in the present embodiment, since the purpose is to quickly start the TV receiver 10 from a state in which the power is turned off, the three modes will be described in detail.

  Hereinafter, the detailed configuration of the sub-microcomputer 39 will be described with reference to FIG. FIG. 1 is a block diagram showing the internal configuration of the sub-microcomputer 39.

  As shown in FIG. 1, the sub-microcomputer 39 has a power supply control unit 41, a setting information holding unit 42, a mode determination unit 43, and a timer 44. When the user turns off the power of the TV receiver 10, the power control unit 41 controls the power supply unit 40 based on what control pattern to determine whether to shift to each mode. In the present embodiment, as a control pattern executed by the power supply control unit 41, (1) supply of power from the power supply unit 40 to the processing unit 46, the output unit 47, and the human sensor 37 is stopped, and the complete standby mode is set. The first control pattern to be transferred, (2) the second control pattern to stop the supply of power from the power supply unit 40 to the output unit 47 and shift to the quick activation mode, and (3) the processing unit 46 and the output There are three control patterns: a standby mode in which the supply of power from the power supply unit 40 to the unit 47 is stopped, and a third control pattern in which the quick start mode is switched as appropriate to shift to the auto quick start mode.

  The mode that is actually used when the TV receiver 10 is turned off can be selected by the user. The mode selected by the user is stored in the setting information holding unit 42 of the sub-microcomputer 39 as setting information. The mode determination unit 43 determines the mode set by the user based on the setting information stored in the setting information holding unit 42. The power supply control unit 41 controls the power supply unit 40 based on the control pattern corresponding to the mode determined by the mode determination unit 43 among the three control patterns.

  The timer 44 measures the elapsed time from the time when the human sensor 37 detects the presence of the user last time. When the elapsed time measured by the timer 44 reaches a predetermined time, the power control unit 41 is configured to end the quick start mode. Specifically, in the auto quick start mode, the power control unit 41 is instructed to stop the power supply to the processing unit 46 of the power supply unit 40 (that is, to shift to the standby mode), thereby quick. The startup mode has been terminated. In this way, switching from the quick start mode to the standby mode is realized.

  Note that the mode information determined by the mode determination unit 43 is output to the timer 44. The timer 44 is activated when the mode information from the mode determination unit 43 is the auto quick activation mode. That is, in the auto quick start mode, measurement of the elapsed time from the time when the human sensor 37 last detects the presence of the user is started. On the other hand, when the complete standby mode or the quick activation mode is set, the timer 44 is not activated even if the presence sensor 37 detects the presence of the user. Therefore, in the complete standby mode or the quick start mode, the standby mode is not switched.

(Three modes of TV receiver 10)
As described above, among the above three modes, the mode that is actually used when the power of the TV receiver 10 is turned off can be selected by the user. For example, the user can select one mode from three modes via the remote controller 36. Specifically, an instruction can be given from the remote control 36 to the sub-microcomputer 39 by the user via the remote control light receiving unit 35. The remote controller 36 is provided with a plurality of buttons or switches and the like for receiving various instructions from the user.

  Hereinafter, a process in which the user sets a desired mode from the three modes will be described with reference to FIG. FIG. 3 is a display example of a menu screen displayed on the liquid crystal display device 22 when setting a mode.

  First, the user gives an instruction for setting the mode to the TV receiver 10 via the remote controller 36. Then, the display controller 21 controls the liquid crystal display device 22 so that a menu screen is displayed on the liquid crystal display device 22. Specifically, options corresponding to the three modes are displayed on the liquid crystal display device 22, as shown in FIG. In the present embodiment, three options of (a) not to be performed, (b) to be performed, and (c) to (auto) are displayed with respect to whether or not the quick activation is set. Here, (a) corresponds to the complete standby mode, (b) corresponds to the quick start mode, and (c) corresponds to the auto quick start mode. When the user selects any one of the three options via the remote controller 36, the display control unit 23 controls the liquid crystal display device 22, so that the selected option is highlighted (in the drawing). , "No" is highlighted). Then, the mode corresponding to the option selected by the user is stored in the setting information holding unit 42 of the sub-microcomputer 39. Then, the liquid crystal display device 22 exits from the setting screen and returns to the normal screen.

  This completes the setting of the mode used when the power button is pressed (turns off the power) while the TV receiver 10 is activated. Therefore, if the power is turned off while the TV receiver 10 is activated, the mode is changed to the mode set by the user. Therefore, hereinafter, a process of shifting to the mode set by the user when the power of the TV receiver 10 is turned off will be described with reference to FIG. FIG. 4 is a flowchart showing a process of shifting to each mode when the TV receiver 10 is turned off.

  For example, when the power of the TV receiver 10 is turned off (step S1), the mode determination unit 43 of the sub-microcomputer 39 determines the mode set by the user based on the setting information stored in the setting information holding unit 42. (Step S2). At this time, if the quick start mode is not set (NO), the process shifts to the complete standby mode (step S3). On the other hand, if the quick start mode is set (step S2, YES), the process proceeds to the quick start mode or the auto quick start mode. At this time, it is determined whether or not the user has further set the auto quick start mode (step S4). If the user has set the auto quick start mode (YES), the process proceeds to the auto quick start mode (step S5). On the other hand, when the auto quick start mode is not set (step S4, NO), the process shifts to the quick start mode (step S6). In this way, the mode determination unit 43 determines the mode set by the user, which is stored in the setting information holding unit 42, and the power supply control unit 41 determines a member for supplying power to the power supply unit 40 based on the mode determination unit 43. .

(Full standby mode)
Next, a process (power control method) in which the sub-microcomputer 39 executes the mode based on the mode set as described above will be described. First, the process of executing the complete standby mode will be described with reference to FIG. FIG. 5 is a flowchart showing a process of switching to the complete standby mode when the power of the TV receiver 10 is turned off.

  First, when the user presses the power button to turn off the TV receiver 10, the mode determination unit 43 determines the mode set by the user based on the setting information stored in the setting information holding unit 42. A flow when the mode determination unit 43 determines that the mode is the complete standby mode will be described below.

  When the mode determination unit 43 determines that the mode set by the user is the complete standby mode, the mode information is output to the power supply control unit 41 and the timer 44. The power supply control unit 41 controls the power supply unit 40 to turn off (stop) the power supply to the output unit 47 based on the information from the mode determination unit 43 (step S11). Next, the power supply unit 40 is controlled to turn off the power supply to the processing unit 46 (step S12), and similarly, the power supply unit 40 is controlled to turn off the power supply to the human sensor 37 (step S12). Step S13). As a result, power supply to members other than the sub-microcomputer 39 and the remote control light receiving unit 35 is stopped, and the TV receiver 10 is in a standby state in the complete standby mode.

  On the other hand, the timer 44 invalidates its own function based on the mode information from the mode determination unit 43. Therefore, if the user does not turn on the power of the TV receiver 10 via the remote controller 36 at this time (step S14, NO), the complete standby mode is continued indefinitely. At this time, when the user turns on the power of the TV receiver 10 via the remote controller 36 (YES), the remote controller light receiving unit 35 receives an optical signal from the remote controller 36. The remote control light receiving unit 35 transmits a control signal from the remote control 36 to the sub-microcomputer 39 via the bus. In the sub-microcomputer 39, based on the control signal from the remote control light receiving unit 35, the power supply control unit 41 controls the power supply unit 40 so as to turn on (start) the power supply to the processing unit 46 (step S15). Next, the power supply unit 40 is controlled to turn on the power supply to the human sensor 37 (step S16), and similarly the power supply unit 40 to turn on the power supply to the output unit 47 human sensor 37. Is controlled (step S17).

  Thus, the user can view the TV receiver 10 by turning on the power of the TV receiver 10 that has been in standby in the complete standby mode (step S18).

(Quick launch mode)
Next, the process of executing the quick start mode will be described with reference to FIG. FIG. 6 is a flowchart showing a process of switching to the quick start mode when the power of the TV receiver 10 is turned off.

  First, when the TV receiver 10 is turned off by the user pressing the power button, the mode determination unit 43 determines the mode set by the user based on the setting information stored in the setting information holding unit 42. . A flow when the mode determination unit 43 determines that the mode is the quick activation mode will be described below.

  When the mode determination unit 43 determines that the mode set by the user is the quick start mode, the mode information is output to the power control unit 41 and the timer 44. The power supply control unit 41 controls the power supply unit 40 to turn off the power supply to the output unit 47 based on the information from the mode determination unit 43 (step S21). As a result, the power supply to the output unit 47 is stopped, and the TV receiver 10 is in a standby state in the quick start mode.

  On the other hand, the timer 44 invalidates its own function based on the mode information from the mode determination unit 43. Therefore, if the user does not turn on the power of the TV receiver 10 via the remote controller 36 at this time (step S22, NO), the quick activation mode is continued indefinitely. At this time, when the user turns on the power of the TV receiver 10 via the remote controller 36 (YES), the remote controller light receiving unit 35 receives an optical signal from the remote controller 36. The remote control light receiving unit 35 transmits a control signal from the remote control 36 to the sub-microcomputer 39 via the bus. In the sub-microcomputer 39, based on the control signal from the remote control light receiving unit 35, the power supply control unit 41 controls the power supply unit 40 to turn on the power supply to the output unit 47 (step S23).

  Thus, the user can view the TV receiver 10 by turning on the power of the TV receiver 10 that has been in standby in the quick start mode (step S24).

  In the quick start mode described above, power supply to the output unit 47 is stopped, and power is supplied to members other than the output unit 47. Therefore, when the user turns on the power of the TV receiver 10, it is only necessary to supply power to the output unit 47. Therefore, it takes a very short time to start the TV receiver 10 completely from the quick start mode. (Steps after Step S22). On the other hand, in the complete standby mode, power supply to other than the sub-microcomputer 39 and the remote control light receiving unit 35 is stopped. Therefore, when the user turns on the TV receiver 10, it is necessary to supply power to members other than the sub-microcomputer 39 and the remote control light receiving unit 35. In particular, since the processing unit 46 includes many members, a large amount of power is required to start up, and it takes time to start up. Therefore, it takes time to completely start the TV receiver 10 from the complete standby mode (steps after step S14).

  As described above, in the quick start mode, it takes less time to start the TV receiver 10 than in the complete standby mode. Therefore, if the TV receiver 10 is in the quick start mode, when the user turns on the power of the TV receiver 10, the TV receiver 10 starts up immediately, so that it is awaited for actual viewing. There is nothing. That is, when the user wants to view the TV receiver 10 immediately, the user can view the TV receiver 10 immediately without dissatisfaction.

  Here, in the quick start mode, the quick start mode can be set for a predetermined time without invalidating the timer 44. Specifically, based on the timer 44, when the time elapsed since the human sensor 37 last detected the user has passed a predetermined time, the processing unit 46 of the power supply control unit 41 and the output The power supply to the unit 47 may be turned off. That is, it may be configured to shift to the standby mode. Alternatively, when the TV receiver 10 is not turned on for a predetermined time, it may be configured to shift to the standby mode.

(Auto quick start mode)
Next, the process of executing the auto quick start mode will be described with reference to FIG. FIG. 7 is a flowchart showing a process of switching to the auto quick start mode when the TV receiver 10 is turned off.

  First, when the TV receiver 10 is turned off by the user pressing the power button, the mode determination unit 43 determines the mode set by the user based on the setting information stored in the setting information holding unit 42. . A flow when the mode determination unit 43 determines that the mode is the auto quick start mode will be described below.

  When the mode determination unit 43 determines that the mode set by the user is the auto quick start mode, the mode information is output to the power supply control unit 41 and the timer 44. The power supply control unit 41 controls the power supply unit 40 so as to turn off the power supply to the output unit 47 based on information from the mode determination unit 43 (step S31). As a result, the power supply to the output unit 47 is stopped, and the TV receiver 10 is in a standby state in the quick start mode.

  On the other hand, the timer 44 validates its own function based on the mode information from the mode determination unit 43. Therefore, when the human sensor 37 detects the presence of the user, the timer 44 starts measuring the elapsed time from the time of detection. If the user is detected again after the human sensor 37 starts measuring the elapsed time, the elapsed time is reset, and the elapsed time starts to be measured again from the time when the user is detected again.

  When the human sensor 37 detects the user (step S32, YES) and the user turns on the TV receiver 10 via the remote controller 36 (step S39, YES), the remote controller 36 The remote control light receiving unit 35 receives the optical signal. The remote control light receiving unit 35 transmits a control signal from the remote control 36 to the sub-microcomputer 39 via the bus. The sub-microcomputer 39 controls the power supply unit 40 so that the power supply control unit 41 turns on the power supply to the output unit 47 based on the control signal from the remote control light receiving unit 35 (step S40). Then, the TV receiver 10 is activated and the user can view the TV receiver 10 (step S41).

  On the other hand, when the presence sensor 37 detects the presence of the user (step S32, YES) and the user has not turned on the TV receiver 10 (step S39, NO), the process returns to step S32. Repeated detection of user presence. Note that when 10 minutes have elapsed since the timer 44 last detected the user (step S33, YES), the information is output to the power control unit 41. Based on the information from the timer 44, the power supply control unit 41 controls the power supply unit 40 to turn off the power supply to the processing unit 46 (step S34). As a result, the power supply to the processing unit 46 is stopped, and the TV receiver 10 shifts from the quick start mode to the standby mode.

  Note that the user may turn on the TV receiver 10 via the remote controller 36 from a location outside the range where the human sensor 37 can detect the user. Therefore, when the measurement time of the timer 44 is less than 10 minutes (step S33, NO), when the user turns on the TV receiver 10 via the remote controller 36 from a place outside the detection range of the human sensor 37. (Step S39, YES), the remote control light receiving unit 35 receives the optical signal from the remote control 36. The remote control light receiving unit 35 transmits a control signal from the remote control 36 to the sub-microcomputer 39 via the bus. The sub-microcomputer 39 controls the power supply unit 40 so that the power supply control unit 41 turns on the power supply to the output unit 47 based on the control signal from the remote control light receiving unit 35 (step S40). Then, the TV receiver 10 is activated and the user can view the TV receiver 10 (step S41). On the other hand, if the user has not turned on the TV receiver 10 via the remote controller 36 (step S39, NO), the process returns to step S32 to repeatedly detect the presence of the user.

  As described above, in the automatic quick start mode, when 10 minutes have passed since the human sensor 37 last detected the user, the power supply to the processing unit 46 is stopped and the quick start mode is switched to the standby mode. It is configured. In other words, even when the TV receiver 10 is in the quick start mode, if the human sensor 37 does not detect the user for a while, such as when the user leaves the seat for a while, the standby mode is automatically entered. Transition.

  As described above, the user may turn on the TV receiver 10 via the remote controller 36 from a place outside the range where the human sensor 37 can detect the user. Therefore, even when the human sensor 37 has not detected the presence of the user after the TV receiver 10 has shifted to the standby mode (step S35, NO), the user is from a place outside the detection range of the human sensor 37. When the power source of the TV receiver 10 is turned on via the remote controller 36 (YES in step S36), the remote controller light receiving unit 35 receives an optical signal from the remote controller 36. The remote control light receiving unit 35 transmits a control signal from the remote control 36 to the sub-microcomputer 39 via the bus. The sub-microcomputer 39 controls the power supply unit 40 to turn on the power supply to the processing unit 46 based on the control signal from the remote control light receiving unit 35 (step S37). Subsequently, the sub-microcomputer 39 controls the power supply unit 40 so that the power supply control unit 41 turns on the power supply to the output unit 47 (step S40). Then, the TV receiver 10 is activated and the user can view the TV receiver 10 (step S41). On the other hand, when the user has not turned on the power of the TV receiver 10 via the remote controller 36 (NO in step S36), the process returns to step S35 and the user detection is repeated until the user is detected. Here, when the human sensor 37 detects the presence of the user (YES), the information is output to the power supply control unit 41. The power supply control unit 41 controls the power supply unit 40 so as to turn on the power supply to the processing unit 46 based on information from the human sensor 37 (step S38). Thereby, the power supply to the processing unit 46 is started, and the TV receiver 10 shifts from the standby mode to the quick activation mode.

  Here, when the user turns on the power of the TV receiver 10 via the remote controller 36 (step S39, YES), the remote controller light receiving unit 35 receives the optical signal from the remote controller 36. The remote control light receiving unit 35 transmits a control signal from the remote control 36 to the sub-microcomputer 39 via the bus. The sub-microcomputer 39 controls the power supply unit 40 so that the power supply control unit 41 turns on the power supply to the output unit 47 based on the control signal from the remote control light receiving unit 35 (step S40). Then, the TV receiver 10 is activated and the user can view the TV receiver 10 (step S41). If the user does not turn on the TV receiver 10 (NO in step S39), the process returns to step S32, and the human sensor 37 continues to detect the presence of the user.

  As described above, the auto quick start mode is configured to switch back to the quick start mode when the human sensor 37 detects the presence of the user even after the quick start mode is switched to the standby mode. That is, even when the TV receiver 10 is in the standby mode, when the user visits the TV receiver 10, the mode automatically shifts to the quick activation mode.

  Accordingly, in the auto quick start mode, when the user leaves the seat for a while from the vicinity of the TV receiver 10, for example, the quick start mode is automatically switched to the standby mode. After that, when the user visits the TV receiver 10 again, the standby mode is automatically switched to the quick start mode. In this way, it is detected whether or not there is a user around the TV receiver 10, and the quick start mode and the standby mode are appropriately switched accordingly. According to this, when the user is near the TV receiver 10, the TV receiver 10 is always on standby in the quick start mode, so that the TV receiver 10 can be started immediately even when the power is turned on. Can do. That is, even if the TV receiver 10 is once turned off, it can be started up in less time if the viewer turns on the power.

  In the quick activation mode (shown in FIG. 6) described above, the quick activation mode continues indefinitely until the user turns on the TV receiver 10. In this case, the quick activation mode is continued even when the user is out of the office or takes a seat for a while. In the quick start mode, power supply to the output unit 47 is stopped. In other words, power is always supplied to members other than the output unit 47. In particular, since the processing unit 46 includes many members as described above, a large amount of power is required to maintain the state where the processing unit 46 is activated. Therefore, in the quick start mode, the power consumption of the TV receiver 10 is large even though the power of the TV receiver 10 is turned off. Therefore, in the auto quick start mode described above, the user automatically switches to the standby mode when the user is out of the office or takes a seat for a while. As a result, it is possible to prevent wasted power from being consumed while the user is out or for a while.

  In the above description, the mode is switched to the standby mode when 10 minutes have elapsed since the last time the human sensor 37 detected the user, but this is not necessarily limited thereto. For example, a suitable time can be set according to the situation. A plurality of candidates may be posted to the user, and the time selected by the user may be adopted.

  Further, a power lamp such as an LED (Light Emitting Diode) may be provided at the lower part of the display screen of the TV receiver 10 so that the user can check the current mode of the TV receiver 10 with the power lamp. For example, the status of the TV receiver 10 can be monitored by emitting the power lamp in red when the TV receiver 10 is in the complete standby mode and the standby mode, and emitting the power lamp in orange when in the quick start mode. It is.

  Furthermore, if the start-up mode according to the present embodiment is also installed in an electronic device linked to the TV receiver 10 such as a recording / reproducing apparatus by HDMI (High-Definition Multimedia Interface), the mode can be shifted to the standby mode or quick. It is possible to shift to the start mode. Therefore, the activation time of the electronic device connected to the TV receiver 10 can be shortened together with the TV receiver 10.

(Combination of motion sensor 37 and OPC sensor 38)
Here, it is considered that the electricity in the room where the TV receiver 10 is installed is turned off while the user is out or sleeping. Therefore, when the room is dark, there is a high possibility that the user will not use the TV receiver 10. Therefore, the OPC sensor 38 of the TV receiver 10 can determine whether the room is bright or not by detecting the brightness around the TV receiver 10. For example, the OPC sensor 38 may measure the amount of ambient external light, and may determine that the room is bright when the amount of light exceeds a predetermined reference amount. Alternatively, the OPC sensor 38 may measure ambient illuminance, and may determine that the room is bright when the illuminance exceeds a predetermined reference.

  In this manner, when the OPC sensor 38 determines that the room is dark, the power supply to the human sensor 37 may be stopped. Specifically, in the auto quick start mode, when the supply of power to the processing unit 46 and the output unit 47 is stopped (step 34 in FIG. 7), if the OPC sensor 38 determines that the room is dark, The power supply control unit 41 is configured to control the power supply unit 40 so that the power supply to the sense sensor 37 is stopped. Here, when the OPC sensor 38 detects that the user has turned on electricity or the like in a dark room and the room has become bright, the power supply control unit 41 turns on the power supply unit 40 to supply power to the human sensor 37. Configure to control.

  At this time, when the supply of power to the processing unit 46 and the output unit 47 is stopped, if the OPC sensor 38 determines that the room is bright, the supply of power to the human sensor 37 is continued.

  According to the above configuration, when the surroundings of the TV receiver 10 are dark, such as when the user is out or sleeping, the supply to the human sensor 37 is stopped. Therefore, since the human sensor 37 is not operating, it is possible to prevent the human sensor 37 from being erroneously detected as a user and preventing power from being supplied to the processing unit 46. As described above, since the electric power is supplied to the human sensor 37 when the user is highly likely to use the TV receiver 10, the accuracy of the human sensor 37 can be further improved. Further, when the human sensor 37 mistakenly detects a user who is not a user, it is possible to prevent power from being supplied to the processing unit 46 one by one, and thus wasteful power consumption can be suppressed.

  When the human sensor 37 and the OPC sensor 38 are used in combination, it is necessary to supply power to the OPC sensor 38 even when the supply of power to the processing unit 46 is stopped. .

  Here, as the human sensor 37, there are an image sensor such as a camera that images an object, a sound sensor that detects sound, a heat sensor that measures heat, a vibration sensor that detects vibration, or a temperature sensor that measures temperature. Applicable.

  For example, when the human sensor 37 is an image sensor, data of a face photograph of a user who uses the TV receiver 10 is stored in the TV receiver 10 in advance. When a person approaches the TV receiver 10 in the standby mode of the auto quick start mode, the image sensor compares the person's face with the stored data of the user's face photograph, and the person is the user. Determine whether or not. When it is determined that the image sensor is a user, the TV receiver 10 is configured to shift from the standby mode to the quick start mode. In this way, the presence of the user can be detected. Note that the TV receiver 10 can store data of face photographs of a plurality of users.

  At this time, a configuration may be adopted in which the mode is shifted to the quick activation mode when the image sensor detects a human face without performing collation of face photograph data.

  Further, when the human sensor 37 is a sound sensor, the sound sensor catches a sound (for example, a user's footsteps or voice) in a region that can be detected by the sound sensor. In the standby mode of the auto quick start mode, when the sound sensor catches the sound, the TV receiver 10 is configured to shift from the standby mode to the quick start mode. In this way, the presence of the user can be detected.

  Furthermore, the human sensor 37 may include a plurality of sensors exemplified above. By having a plurality of sensors, the presence of the user can be detected by any means. The user can also use various sensors in combination. For example, for a user who does not view the TV receiver 10 when the surroundings are dark, the human sensor 37 and the OPC sensor 38 are used together. As a result, when the room is dark, it is possible to prevent power from being supplied to the processing unit 46 one by one when the human sensor 37 erroneously detects a user who is not a user. Consumption can be reduced.

  Note that the various sensors described above are not necessarily installed in the TV receiver 10 itself. For example, when the human sensor 37 is mounted on a portable electronic device such as a remote control 36, a mobile phone, or a terminal device, and the human sensor 37 detects that the user lifts the device or approaches the device, The detection signal may be transmitted to the TV receiver 10. Specifically, the detection signal from the human sensor 37 may be transmitted to the sub-microcomputer 39 via the remote control light receiving unit 35 or another receiving unit. In this case, the detection signal from the human sensor 37 can be transmitted by a communication method such as optical (infrared) communication, radio wave communication, or ultrasonic communication.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope shown in the claims. That is, embodiments obtained by combining technical means appropriately modified within the scope of the claims are also included in the technical scope of the present invention.

  For example, when the TV receiver 10 itself has a function of recording a television program, the auto quick start mode may not be operated while the TV receiver 10 is recording the television program. Also, when the auto-quick start mode is installed in the PC built-in TV, it is preferable that the auto-quick start mode does not operate while the PC built-in TV is downloading a program or updating. . As described above, whether or not to activate the auto quick start mode may be determined in accordance with an electronic device equipped with the start mode according to the present embodiment while various functions of the electronic device are in operation.

  In the above description, a TV receiver is particularly described as an example. However, other electronic devices such as a recording / reproducing apparatus or an audio component that are turned on / off by a power switch are also exemplified. It is clear that the invention of the present application can also be applied to AV equipment (content reproduction apparatus).

  The recording medium for supplying the program code to the television receiver 10 is not limited to a specific structure or type. That is, the recording medium includes, for example, a tape system such as a magnetic tape and a cassette tape, a magnetic disk such as a floppy (registered trademark) disk / hard disk, and an optical disk such as a CD-ROM / MO / MD / DVD / CD-R. System, a card system such as an IC card (including a memory card) / optical card, or a semiconductor memory system such as a mask ROM / EPROM / EEPROM / flash ROM.

  Moreover, even if the TV receiver 10 is configured to be connectable to a communication network, the object of the present invention can be achieved. In this case, the program code is supplied to the TV receiver 10 via the communication network. The communication network is not limited to a specific type or form as long as it can supply program codes to the TV receiver 10. For example, the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, or satellite communication network may be used.

  The transmission medium constituting the communication network may be any medium that can transmit the program code, and is not limited to a specific configuration or type.
