For example, a receiving device (Set Top Box) for receiving the received video. In the following, the video output device 1 will be described as an example of the tuner 1 that receives video related to terrestrial digital broadcasting and outputs the received video to the display device 2.

  The tuner 1 outputs AV (Audio and Visual) data including video data and audio data obtained by performing signal processing on the broadcast signal to the display device 2. The display device 2 physically separated from the tuner 1 is, for example, a liquid crystal display, an organic EL (Electroluminescence) display, or a plasma display, and displays video data and outputs audio data. Hereinafter, the display device 2 will be described as the liquid crystal display 2.

  The liquid crystal display 2 is attached to the wall 5 with a bolt or the like, or is embedded in the recess of the wall 5 with its display surface exposed. In addition, the liquid crystal display 2 may be placed on a rack (not shown), and the rack may be installed near the wall 5. Below, the liquid crystal display 2 is demonstrated using the example attached to the wall 5. FIG. The tuner 1 is placed on a rack 51 protruding from the wall 5. Note that the tuner 1 may be placed on a rack installed on the floor, in addition to being placed on the rack 51, or may be buried with the front face exposed in the recess of the wall 5. The tuner 1 and the display device 2 are connected via a communication line 4 and transmit / receive AV data and various control data. In the present embodiment, an example is described in which the communication line 4 uses the HDMI cable 4 based on the HDMI (High-Definition Multimedia Interface: registered trademark) standard, but the present invention is not limited to this. In addition to cables based on other standards, AV data and various control data may be transmitted and received by wireless communication using a 60 GHz band millimeter wave or the like.

  The display unit 24 such as a display module including the liquid crystal panel of the liquid crystal display 2 displays video data and also displays image data stored therein as will be described later. An LED (Light-Emitting Diode) 22 is arranged on the bottom of the front of the liquid crystal display 2 with the front facing. The LED 22 emits light when displaying video data. A slot 211 for inserting the portable recording medium 6 is provided on the right side surface of the liquid crystal display 2. The portable recording medium 6 is, for example, a USB memory, an SD (registered trademark) card, or a memory card, in which image data to be displayed on the display unit 24 is stored.

  In the following description, it is assumed that the portable recording medium 6 is a USB memory 6 and the slot 211 is a USB slot 211. When the USB memory 6 is attached to the USB slot 211, the liquid crystal display 2 reads the image data in the USB memory 6 and displays the read image on the display unit 24. The remote operation device 3 is a remote operation device using, for example, an infrared method, Bluetooth (registered trademark), or RF method, and transmits an operation signal to the tuner 1 or the liquid crystal display 2. Hereinafter, an example using Bluetooth will be described, and the remote operation device 3 will be described as the remote controller 3. The remote controller 3 is provided with a power key 331, a picture key 332, and an end key 333 in addition to various operation keys. The remote controller 3 may be prepared separately for the tuner 1 and the liquid crystal display 2.

  When the picture key 332 is operated, operation data as instruction information for displaying the image data stored in the storage unit 25 of the liquid crystal display 2 is transmitted to the reception unit 16 via the transmission unit 36. When the end key 333 is operated, operation data as resumption information for resuming output of video data and reception of broadcast to the tuner 1 is transmitted to the reception unit 16 via the transmission unit 36. Returning to FIG. 2, the clock unit 18 outputs date and time information to the first control unit 11. The tuner 1 and the liquid crystal display 2 are connected via an HDMI cable 4, and AV data is transmitted / received via the HDMI line 41 and various control information is transmitted / received via the CEC line 42.

  The first control unit 11 is connected to the second control unit 21 of the liquid crystal display 2 via the CEC line 42, and transmits and receives information based on the HDMI standard. The broadcast receiving unit 19 receives a television broadcast signal. Note that although an example in which data related to digital broadcasting is received will be described in this embodiment, an analog broadcasting signal may be received. The tuner 1 receives a data stream related to digital broadcasting transmitted by a protocol such as MPEG (Moving Pictures Experts Group) -2. The tuner 1 performs demodulation processing, decoding processing, and the like, and outputs the AV data subjected to the processing such as demodulation to the signal processing unit 191.

  The signal processing unit 191 includes a correction circuit that corrects each color of R, G, and B, and a scaler that converts various video signal formats into the number of pixels that can be displayed on the display unit 24. AV data on which image processing or the like has been performed by the signal processing unit 191 is output to the HDMI signal transmission unit 192. The HDMI signal transmission unit 192 transmits AV data to the HDMI signal reception unit 292 of the liquid crystal display 2 via the HDMI line 41.

  Next, the liquid crystal display 2 will be described. The HDMI signal receiving unit 292 outputs the received AV data to the signal processing unit 29. The signal processing unit 29 separates the video data and the audio data, outputs the video data to the data separation unit 291, and outputs the audio data to the speaker 293 in synchronization with the output of the video data. The data separation unit 291 is connected to the display unit 24 and the LED backlight 210 which are liquid crystal display modules. A backlight using a cold cathode tube may be used instead of the LED backlight 210. The data separation unit 291 separates the LED data included in the video data, and outputs the separated video data to the display unit 24 and the separated LED data to the LED backlight 210.

  The signal processing unit 29 performs display control of the display unit 24 and PWM (Pulse-Width Modulation) control of the LED backlight 210 under the instruction of the second control unit 21. Information relating to the pulse width is output to the LED data as information relating to the luminous intensity adjustment of the LED. In this embodiment, an example in which the brightness control of the LED backlight 210 is performed by PWM control will be described. However, the brightness may be controlled by changing a current value. The second control unit 21 is connected to each hardware unit of the liquid crystal display 2 via the bus 27 and controls them, and according to the control program 25P stored in the storage unit 25, various control units according to the present embodiment. Perform software functions. The LED 22 is, for example, a green LED, and is lit when displaying video data on the display unit 24. The input unit 23 is various operation buttons provided on a side surface of the liquid crystal display 2 and outputs operation data associated with the operation to the second control unit 21.

  The receiving unit 26 receives operation data from a remote controller 3 for the liquid crystal display 2 (not shown), and outputs the received operation data to the second control unit 21. In the present embodiment, an example in which operation data transmitted from the remote controller 3 is transmitted to the receiving unit 16 of the tuner 1 will be described, but the present invention is not limited to this. The operation data transmitted from the remote controller 3 may be received by the receiving unit 26 of the liquid crystal display 2. In this case, the operation data is output to the second control unit 21, and the second control unit 21 outputs the operation data to the first control unit 11 via the CEC line 42. The clock unit 28 outputs date and time information to the second control unit 21.

  The storage unit 25 configured by a large-capacity memory or the like stores an image data file 251 and a mode file 252 in addition to the control program 25P described above. The image data file 251 may be stored in a dedicated memory (not shown). The image data file 251 stores image data in a format such as JPEG (Joint Photographic Experts Group). Similarly, an image data file 65 storing image data taken by the user is also stored in the USB memory 6. When video data is displayed on the display unit 24, a user who desires to display image data operates the picture key 332 of the remote controller 3.

  The control unit 31 receives operation data (hereinafter referred to as first operation data) output from the picture key 332 and transmits the first operation data via the transmission unit 36. The receiving unit 16 of the tuner 1 outputs the received first operation data to the first control unit 11. The first control unit 11 outputs the first operation data to the second control unit 21 via the CEC line 42. In accordance with this, the first control unit 11 stops the reception of the broadcast, and stops the output of the video data from the HDMI signal transmission unit 192. Note that the output of audio data is also stopped. In the following, description regarding audio data is omitted as appropriate. Further, the first control unit 11 turns off the second LED 122 that was turned on when receiving the broadcast and outputting the video data, and turns on the first LED 121. As a result, the tuner 1 enters a standby state. Note that the power supply of the tuner 1 is not completely turned off, and the receiving unit 16 can continuously receive operation data.

  The liquid crystal display 2 stops displaying the video data when the output of the video data is stopped. The second control unit 21 that has received the first operation data via the CEC line 42 reads out the image data stored in the image data file 251 and outputs it to the display unit 24. The second control unit 21 turns off the LED 22 triggered by the reception of the first operation data. In the present embodiment, an example in which the LED 22 is turned off will be described, but it may be reduced. For example, the second control unit 21 outputs a light reduction signal to the LED control unit (not shown), and the LED control unit receives the signal and outputs the LED 22 to a predetermined output (for example, about 10%) by, for example, PWM control. Output). In the present embodiment, the LED 22 that emits light when an image is displayed will be described as an example. However, the present invention is not limited to this. For example, an LED (not shown) that lights up when a viewing reservation or a recording reservation is set, and an LED (not shown) that lights up when a sleep mode is set to shift the liquid crystal display to a standby state after a predetermined time has elapsed. Or an LED (not shown) indicating that a brightness sensor (not shown) for detecting the brightness around the liquid crystal display 2 is operating, depending on the setting or operating state of the liquid crystal display 2 The LED that emits light may also be turned off or turned off when the first operation data is received. When the USB memory 6 is attached to the USB slot 211, the second control unit 21 reads out the image data from the image data file 65 and similarly displays it on the display unit 24. When a plurality of image data is stored in the image data file 251 or the image data file 65, the second control unit 21 refers to the date and time output from the clock unit 28, and switches and displays the image data at regular intervals. .

  FIG. 5 is an explanatory diagram showing a record layout of the mode file 252. The mode file 252 stores information on the intensity of the LED backlight 210 in association with the mode. The mode file 252 includes a mode field, an LED intensity field, and a time field. A plurality of modes are stored in the mode field. The LED intensity field stores the maximum intensity of the LED backlight 210 to be set in association with the mode. For example, mode 1 stores 100% as a reference as the maximum light emission intensity of the LED backlight 210 when displaying video data. Note that 100% is the maximum light emission intensity, and is increased or decreased as appropriate from 0% to 100%, with 100% being the maximum, depending on the luminance related to the video data.

  In contrast, mode 2 is a mode that is selected when the first operation data associated with the operation of the picture key 332 is received. In mode 2, for example, 30% is stored in the LED intensity field in order to save power. In the case of mode 2, when displaying image data, the maximum light emission intensity is 30%, which is 70% lower than that in mode 1, and is increased or decreased appropriately between 0% and 30%. When image data is displayed, it may be fixed at 30%. To further save power, mode 3 is selected. In mode 3, the LED intensity is stored as a maximum emission intensity of 10% with respect to mode 1. In the case of mode 3, PWM control is performed so as to increase / decrease appropriately between 0% and 10%. The user can select a mode when displaying image data from the remote controller 3 or the input unit 23 and change the LED intensity value. Further, as shown in FIG. 5, a time field may be provided and the mode may be changed according to the time zone. In the time field, time is stored in association with modes 2 and 3 selected when the first operation data is output. The second control unit 21 reads a mode corresponding to the time output from the clock unit 28 when displaying the image data from the mode file 252.

  For example, Mode 2 with high LED intensity is read from 9 am to 5 pm. The second control unit 21 outputs a command to the signal processing unit 29 to execute control in which the LED intensity is 30% with respect to the video data display time. On the other hand, mode 3 is selected from 5: 1 in the evening to 8:59 am, which does not require the control to make the surroundings dark and so bright. The second control unit 21 outputs a command to the signal processing unit 29 to execute control that causes the LED intensity to be 10% with respect to the video data display time. The time field value can also be set to an appropriate time through the remote controller 3 or the like.

  When the end key 333 is input from the remote controller 3, the control unit 31 receives operation data (hereinafter referred to as second operation data) as resumption information based on the operation of the end key via the transmission unit 36 and the reception unit 16 of the tuner 1. Send to. When the first control unit 11 of the tuner 1 receives the first operation data via the receiving unit 16, the first operation data is discarded. As described above, an example in which the transmission of information from the remote controller 3 to the tuner 1 is executed between the transmission unit 36 of the remote controller 3 and the reception unit 16 of the tuner 1 based on the Bluetooth standard will be described. It is not a thing. For example, information may be transmitted from the remote controller of the liquid crystal display 2 (not shown) to the receiving unit 26 of the liquid crystal display 2 by infrared rays. In this case, the second control unit 21 outputs the received first operation data or second operation data to the tuner 1 via the CEC line 42. On the other hand, only when the first control unit 11 receives the second operation data, the first control unit 11 activates the broadcast receiving unit 19 again and shifts from the standby state to the on state. The broadcast receiving unit 19 receives the broadcast and outputs video data to the liquid crystal display 2 again via the HDMI signal transmitting unit 192. At the same time, the first control unit 11 turns off the first LED 121 and turns on the second LED 122, and outputs the second operation data to the second control unit 21 of the liquid crystal display 2 via the CEC line 42. The second control unit 21 of the liquid crystal display 2 stops reading image data and displays the video data output via the HDMI signal receiving unit 292 on the display unit 24. The second control unit 21 turns on the LED 22.

  A control procedure related to video data and image data in the above hardware configuration will be described using a flowchart. 6 and 7 are flowcharts showing the display processing procedure of the image data. When the first control unit 11 of the tuner 1 receives an ON signal based on the operation of the power key 331 from the remote controller 3, the first control unit 11 activates the broadcast receiving unit 19 and receives a digital broadcast (step S61). The first control unit 11 turns on the first LED 121 in the lit state from on to off, and turns off the second LED 122 in the unlit state from the off state, triggered by the activation of the broadcast receiving unit 19 (step S62). The tuner 1 processes the broadcast signal in the signal processing unit 191 and outputs the video data after the signal processing to the HDMI signal transmission unit 192. The tuner 1 outputs video data to the liquid crystal display 2 via the HDMI line 41 by the HDMI signal transmission unit 192 (step S63).

  The second control unit 21 of the liquid crystal display 2 activates each internal hardware and receives the video data via the HDMI signal receiving unit 292 (step S64). The 2nd control part 21 turns on LED22 in a light extinction state from OFF (step S65). The second control unit 21 reads the LED intensity corresponding to mode 1 from the mode file 252 (step S66). In this example, the maximum luminance is set to 100%. The second control unit 21 outputs the read LED intensity to the signal processing unit 29 (step S67). The signal processing unit 29 controls the light amount of the LED backlight 210 based on various control information for each mode including the LED intensity. The signal processing unit 29 displays the video data on the display unit 24 (step S68).

  Processing when the user who is watching TV through the above processing operates the picture key 332 of the remote controller 3 to shift to the painting mode will be described. The first control unit 11 determines whether or not the first operation data based on the operation of the picture key 332 is received from the remote controller 3 via the reception unit 16 (step S69). If the first control unit 11 determines that the first operation data is not received (NO in step S69), the first control unit 11 waits until the first operation data is received. On the other hand, if the first control unit 11 determines that the first operation data has been received (YES in step S69), the broadcast receiving unit 19 is stopped, the broadcast reception is stopped, and the signal processing unit 191 and the HDMI signal transmitting unit are stopped. 192 is stopped and the output of the video data to the liquid crystal display 2 is stopped (step S71).

  Thereby, the display of the video data on the display unit 24 of the liquid crystal display 2 is stopped. The first controller 11 turns the first LED 121 from off to on, and turns the second LED 122 off from on (step S72). In this case, the first control unit 11 may turn off both the first LED 121 and the second LED 122. As a result, the tuner 1 shifts to a standby state in which the broadcast receiving unit 19 is turned off while the receiving unit 16 can receive operation data, thereby saving power. The first control unit 11 of the tuner 1 outputs the first operation data to the liquid crystal display 2 via the CEC line 42 (step S73).

  The second control unit 21 of the liquid crystal display 2 receives the first operation data output via the CEC line 42 (step S74). The second control unit 21 determines whether or not the USB memory 6 is attached to the USB slot 211 (step S75). If the second control unit 21 determines that the USB memory 6 is not attached (NO in step S75), the second control unit 21 reads the image data stored in the image data file 251 in the storage unit 25 (step S77). On the other hand, if the second control unit 21 determines that the USB memory 6 is attached (YES in step S75), it reads image data from the image data file 65 in the USB memory 6 (step S76).

  The 2nd control part 21 turns off LED22 in a lighting state (Step S78). Thereby, the glare at the time of appreciation of a picture can be reduced, and it becomes possible to produce the appearance as a picture in a forehead. In the present embodiment, the example in which the LED 22 is turned off has been described. However, another LED (not shown) having a color different from that of the LED 22 may be further provided on the front surface of the casing of the liquid crystal display 2. For example, the LED 22 may be green and the other LEDs may be red. When the second control unit 21 turns off the LED 22 in step S78, the second control unit 21 turns on the other LEDs. Conversely, when the second control unit 21 turns on the LED 22, it turns off the other LEDs. The second control unit 21 acquires the current time output from the clock unit 28 (step S79). The second control unit 21 reads the LED intensity corresponding to the time from the mode file 252 (step S710). The second control unit 21 outputs the read LED intensity to the signal processing unit 29 (step S711). The signal processing unit 29 performs PWM control on the LED backlight according to the LED intensity corresponding to time. The signal processing unit 29 outputs the image data read out in step S76 or step S77 to the display unit 24 and displays it (step S712). Therefore, it is possible to save power in both the tuner 1 and the liquid crystal display 2.

  8 and 9 are flowcharts showing a procedure for resuming the display of the video data after the image data is displayed. When the first operation data is output in step S73 and the image data is displayed on the liquid crystal display 2 in step S712, the first control unit 11 in the standby state receives the first operation from the remote controller 3 via the reception unit 16. It is determined whether or not operation data has been received (step S81). When determining that the first operation data has been received (YES in step S81), the first control unit 11 discards the received first operation data (step S82). Specifically, even if the first control unit 11 receives the first operation data, the broadcast reception unit 19 activates the broadcast reception, the video data output, the first LED 121 off, the second LED 122 on, the liquid crystal display 2. Control that does not execute processing based on the first operation data, including transmission of the second operation data to is performed. Thereafter, the process returns to step S81.

  If the first control unit 11 determines that the first operation data has not been received (NO in step S81), the first control unit 11 determines whether the second operation data has been received (step S83). Specifically, it is determined whether or not the receiving unit 16 has received the second operation data transmitted from the remote controller 3 when the user operates the end key 333 of the remote controller 3. If the first control unit 11 determines that the second operation data has not been received (NO in step S83), the process returns to step S81 again. On the other hand, if the first control unit 11 determines that the second operation data has been received (YES in step S83), the first control unit 11 activates the broadcast receiving unit 19 and resumes reception of the digital broadcast (step S84). That is, the standby state shifts to the on state.

  The first control unit 11 turns the first LED 121 that is lit in red from on to off, and turns the second LED 122 that is off from off to on (step S85). The first control unit 11 outputs the second operation data to the second control unit 21 via the CEC line 42 (step S86). Since a predetermined time is required for the broadcast reception processing in the broadcast receiving unit 19 and the signal processing in the signal processing unit 191 in the tuner 1, the liquid crystal display 2 displays image data in parallel with this, that is, from the picture mode to the video data display. Transition to display processing.

  The second control unit 21 of the liquid crystal display 2 receives the second operation data (step S87). The second control unit 21 stops reading the image data from the image data file 251 in the storage unit 25 or the image data file 65 in the USB memory 6 and stops displaying the image data on the display unit 24 (step S88). . The second control unit 21 turns on the LED 22 that is in the extinguished state from off (step S89). The HDMI signal transmitting unit 192 of the tuner 1 outputs the video data after the signal processing to the HDMI signal receiving unit 292 of the liquid crystal display 2 through the HDMI line 41 (Step S91).

  The HDMI signal receiving unit 292 of the liquid crystal display 2 receives the output video data (step S92). The second control unit 21 reads the LED intensity stored in the mode file 252 (step S93). The second control unit 21 outputs the read LED intensity to the signal processing unit 29. In this example, mode 1 is selected again, and the LED backlight 210 is controlled at a light emission intensity of 100%. The signal processing unit 29 displays video data on the display unit 24 (step S94), and performs PWM control of the LED backlight 210 according to the output LED intensity.

Embodiment 2
The second embodiment relates to processing when a viewing reservation is set. FIG. 10 is a block diagram showing a hardware configuration of tuner 1 according to the second embodiment. In addition to the configuration of the first embodiment, the storage unit 15 is provided with a viewing reservation file 151 as a reservation storage unit. The viewing reservation file 151 stores the date and channel that the user desires to view. The user inputs the date and time and the channel using the input unit 13 or the remote controller 3 by using, for example, an EPG (Electronic Program Guide). The first control unit 11 receives the input date / time and channel, and stores the received date / time and channel in the viewing reservation file 151.

  11 and 12 are flowcharts showing the processing procedure when the viewing reservation time is reached when image data is being displayed. The first control unit 11 receives the viewing reservation date and channel input via the input unit 13 or the receiving unit 16 (step S111). The first control unit 11 stores the received date and channel in the viewing reservation file 151 (step S112). Thereafter, as described in the first embodiment, it is assumed that the picture key 332 is operated and image data is displayed on the liquid crystal display 2. The following processing is performed after the processing in step S712 of the first embodiment.

  The first control unit 11 receives the first operation data from the remote control 3 (or transmits the first operation data to the liquid crystal display 2), stops the broadcast receiving unit 19, stops the output of the video data, and views It is determined whether or not the scheduled date and time has been reached (step S113). Whether or not the scheduled viewing date / time has been reached is determined by determining whether or not the date / time output from the clock unit 18 matches the date / time stored in the viewing reservation file 151. If the first control unit 11 determines that the condition in step S113 is not satisfied (NO in step S113), the first control unit 11 waits until the condition is satisfied. On the other hand, if the first control unit 11 determines that the condition of step S113 is satisfied (YES in step S113), the first control unit 11 activates the broadcast receiving unit 19 and receives the digital broadcast (step S114).

  When the viewing reservation time is reached, the tuner 1 shifts from the standby state to the on state. The first control unit 11 turns the first LED 121 that is lit in red from on to off, and turns the second LED 122 that is off from off to on (step S115). The first control unit 11 outputs resumption data indicating resumption of viewing based on viewing reservation to the second control unit 21 via the CEC line 42 (step S116). Since a predetermined time is required for the broadcast reception processing in the broadcast receiving unit 19 and the signal processing in the signal processing unit 191 in the tuner 1, the liquid crystal display 2 displays image data in parallel with this, that is, from the picture mode to the video data display. Transition to display processing.

  The second control unit 21 of the liquid crystal display 2 receives the restart data (step S117). The second control unit 21 stops reading the image data from the image data file 251 in the storage unit 25 or the image data file 65 in the USB memory 6 and stops displaying the image data on the display unit 24 (step S118). . The second control unit 21 reads music data stored in advance in the storage unit 15 from the storage unit 15 in order to make a natural transition from the picture in the forehead to the television (step S119). The music data may be stored in advance in the storage unit 15 in accordance with the image data image. The second control unit 21 outputs the read music data from the speaker at a previously stored volume (step S121). As a result, the video data can be restarted naturally without destroying the calm atmosphere of the painting mode.

  The second control unit 21 turns on the LED 22 in the extinguished state from off (step S122). The HDMI signal transmitting unit 192 of the tuner 1 outputs the video data after the signal processing to the HDMI signal receiving unit 292 of the liquid crystal display 2 through the HDMI line 41 (Step S123).

  The HDMI signal receiving unit 292 of the liquid crystal display 2 receives the output video data (step S124). The second control unit 21 stops outputting the music data after receiving the video data (step S125). The second control unit 21 reads the LED intensity stored in the mode file 252 (step S126). The second control unit 21 outputs the read LED intensity to the signal processing unit 29. The signal processing unit 29 displays video data on the display unit 24 (step S127), and performs PWM control of the LED backlight 210 according to the output LED intensity. Thereby, even when the image data is displayed, the display of the video data is resumed on the condition that the viewing reservation is made.

  The second embodiment is configured as described above, and other configurations and operations are the same as those of the first embodiment. Therefore, the corresponding parts are denoted by the same reference numerals, and detailed description thereof is omitted.

Embodiment 3
The third embodiment relates to a mode in which other devices are also in an off state or a standby state when displaying image data. FIG. 13 is a schematic diagram showing an outline of a display system according to the third embodiment. The display system further includes a recording device 7, an audio amplifier 8, and a light emitting device 9. The recording device 7 is a device that stores video data in a portable recording medium such as a hard disk or a Blu-ray, and reads out the stored video data for reproduction. In the following description, the recording device 7 is replaced with the recorder 7. The audio amplifier 8 processes the sound output from the tuner 1 and outputs the sound from, for example, a 5.1 channel speaker system.

  Both the recorder 7 and the audio amplifier 8 are connected to the tuner 1 by the HDMI cable 4 and can transmit and receive video data, audio data, or various control signals. The light emitting device 9 is a fluorescent lamp, an incandescent lamp, an LED lamp or the like provided near the liquid crystal display 2. Below, the light-emitting device 9 is demonstrated as what is the LED lamp 9. FIG. The LED lamp 9 is installed in the same room to irradiate the liquid crystal display 2. The LED lamp 9 has a receiving unit 96 inside, and receives first operation data based on the operation of the picture key 332 and second operation data based on the operation of the end key 333, for example, according to the Bluetooth standard.

  When the picture key 332 is operated while the liquid crystal display 2 is displaying video data, the image data is displayed as described in the first embodiment. In this case, the tuner 1 outputs to the recorder 7 and the audio amplifier 8 a switching signal for shifting the device in the on state to the standby state via the CEC line 42. Hereinafter, the switching signal is referred to as first operation data. The recorder 7 in the on state receives the first operation data and shifts to the standby state. Note that the process of shifting the recorder 7 to the standby state will be described later. The audio amplifier 8 shifts to the standby state. Thereby, further power saving can be achieved.

  Thereafter, when the tuner 1 receives the second operation data, the tuner 1 outputs a restart signal for turning on the recorder 7 and the audio amplifier 8 in the standby state to the recorder 7 and the audio amplifier 8. Hereinafter, the restart signal is referred to as second operation data. The recorder 7 and the audio amplifier 8 are turned on again. When the LED lamp 9 is turned on and receives the first operation data output from the picture key 332 by the receiving unit 96, the LED lamp 9 reduces the light emission intensity according to the LED intensity stored in the mode file 951 in the memory 95. The mode file 951 stores the emission intensity and time zone of the LED lamp 9 in association with the mode. For example, 100% emission intensity for mode 1, 20% emission intensity for mode 2, time zone from 9 am to 5 pm, and 5% emission intensity for mode 3 time zone Is stored from 5: 1 pm to 8:59 am.

  The control unit 91 refers to the clock unit 98 and controls the light emission intensity of the LED lamp 9 according to the LED intensity stored in the mode file 951. As a result, when the mode is changed to the painting mode, it is possible to appreciate the image data with a natural light quantity like a museum. When the control unit 91 receives the second operation data via the receiving unit 96, the control unit 91 refers to the mode file 951 and turns on the LED lamp 9 again at the maximum intensity. In this embodiment, one LED lamp 9 is used for ease of explanation, but a plurality of LED lamps 9 may be provided.

  FIG. 14 is a block diagram showing a hardware configuration of the recorder 7. The recorder 7 includes a third control unit 71, a clock unit 78, a hard disk 76H, a hard disk drive control unit 762, a first LED 721, a second LED 722, an input unit 73, a reception unit 76, a display unit 74, a storage unit 75, a control program 75P, a disk drive. 710, a disk control unit 711, a signal reception unit 792, an HDMI signal transmission unit 793, a signal processing unit 79, and the like. The third control unit 71 of the recorder 7 is connected to each part of the hardware via the bus 77 and controls them, and in accordance with the control program 75P stored in the storage unit 75 such as the main memory, The various software functions are executed. The input unit 73 is an operation button or the like provided on the front surface of the casing of the recorder 7 and outputs the input operation data to the third control unit 71.

  The first LED 721 is, for example, an LED that emits red light indicating that it is in a standby state, and is turned on or off according to an instruction from the third control unit 71. The second LED 722 is, for example, an LED that emits blue light indicating that it is in an on state, and is turned on or off in accordance with an instruction from the third control unit 71. The first LED 721 and the second LED 722 are provided on the front surface of the housing of the recorder 7. When the recorder 7 is in the off state, both the first LED 721 and the second LED 722 are in the off state.

  The receiving unit 76 is a transceiver based on the Bluetooth standard that receives operation data from the remote controller 3. In the present embodiment, an example in which the first operation data and the second operation data are received from the tuner 1 via the CEC line 42 will be described, but the present invention is not limited to this. Similarly to the LED lamp 9, the first operation data and the second operation data transmitted from the transmission unit 36 of the remote controller 3 may be directly received by the reception unit 76. The clock unit 78 outputs date and time information to the third control unit 71. The display unit 74 is provided on the front surface of the housing, and displays various information such as the current time and playback time.

  A video file 761 for storing video data is provided in the hard disk 76H. The hard disk drive control unit 762 controls a motor, a head, an arm, and the like that drive the hard disk 76H, and controls reading and writing of video data with respect to the hard disk 76H. The recorder 7 stores and reproduces video data on a portable recording medium 712 such as a DVD (Digital Versatile Disc) or a Blu-ray disc based on the Blu-ray standard. In the following description, it is assumed that the portable recording medium 712 is a Blu-ray disc 712. The disc drive 710 writes and reads video data to and from the Blu-ray disc 712 in accordance with instructions from the disc control unit 711. The disk control unit 711 performs motor control in the disk drive 710, calibration of the optical pickup, and the like.

  The video data transmitted from the tuner 1 is received by the signal receiving unit 792 based on, for example, the iLink (registered trademark) standard. The received video data is subjected to image processing by the signal processing unit 79. The third control unit 71 stores the received video data in the video file 761 or the Blu-ray disc 712 in the hard disk 76H. The video data stored in the video file 761 in the hard disk 76H or the Blu-ray disc 712 is read under the instruction of the third control unit 71, passes through the signal processing unit 79 and the HDMI signal transmission unit 793, and via the HDMI line 41. It is output to the liquid crystal display 2.

  When the recorder 7 is in the ON state, all the hardware including the hard disk 76H, the hard disk drive control unit 762, the disk drive 710, and the disk control unit 711 are activated. The third controller 71 turns off the first LED 721 and turns on the second LED 722. Here, when the first operation data is received from the tuner 1 via the CEC line 42, the hard disk 76H, the hard disk drive control unit 762, the disk drive 710, the disk control unit 711, and the display unit are set to shift to the standby state. 74 is stopped. Further, the third control unit 71 turns on the first LED 721 and turns off the second LED 722. Even when the standby state is entered, the operation signal can be received by the receiving unit 76, and the third control unit 71 can transmit and receive various types of information via the CEC line 42.

  Based on the above hardware configuration, the lighting process and the process for the recorder 7 will be described using a flowchart. 15 and 16 are flowcharts showing the lighting processing procedure. The controller 91 of the LED lamp 9 determines whether or not a lighting instruction has been given from a switch (not shown) (step S151). When it is determined that the lighting instruction has not been received (NO in step S151), the control unit 91 waits until there is a lighting instruction. On the other hand, when the control unit 91 receives a lighting instruction (YES in step S151), the control unit 91 refers to the mode file 951 and causes the LED lamp 9 to emit light at the maximum intensity (step S152).

  The controller 91 determines whether or not the first operation data has been received via the receiver 96 (step S153). If control unit 91 determines that the first operation data has not been received (NO in step S153), the process returns to step S153. If the control unit 91 determines that the first operation data has been received from the remote controller 3 via the receiving unit 96 (YES in step S153), the control unit 91 acquires time from the clock unit 98 (step S154). The controller 91 reads the LED intensity corresponding to the time acquired from the mode file 951 (step S155).

  The controller 91 controls the LED lamp 9 with the read LED intensity (step S156). Thereby, the optimal illuminance can be set according to the time, and it becomes possible to produce a more natural appearance when displaying image data based on a picture. The control unit 91 determines whether or not the second operation data based on the operation of the end key 333 has been received via the receiving unit 96 (step S157). When it is determined that the second operation data has not been received (NO in step S157), the control unit 91 refers to the output of the clock unit 98 and determines whether or not a predetermined time has elapsed (step S158). The time measured for the control process of the LED lamp 9 based on the first operation data in step S156 may be stored in the memory 95 as 3 hours, for example.

  If control unit 91 determines that the predetermined time has not elapsed (NO in step S158), the process returns to step S156. On the other hand, when it is determined that the predetermined time has passed (YES in step S158), the control unit 91 performs control to further reduce the LED intensity (step S159). Specifically, the control unit 91 stores a coefficient (for example, 0.8) in the memory, and multiplies the LED intensity read in step S155. Thereby, with the passage of time, the illuminance of the LED lamp 9 gradually decreases, and further power saving can be achieved.

  After the process of step S159, the process returns to step S157 again. In step S157, when the control unit 91 determines that the second operation data has been received via the receiving unit 96 (YES in step S157), the LED intensity related to the maximum intensity is read from the mode file 951 (step S161). The controller 91 controls the LED lamp 9 with the read LED intensity (step S162). As a result, the user can view the television in a bright environment without any particular intention when viewing the television.

  17 and 18 are flowcharts showing the processing procedure for the recorder 7. When the ON signal is input via the input unit 73 or the receiving unit 76, the third control unit 71 of the recorder 7 activates the hard disk 76H and the hard disk drive control unit 762 (step S171). In the present embodiment, an example in which only the hard disk 76H is activated will be described for ease of explanation. The third control unit 71 turns off the first LED 721 such as red, and turns on the second LED 722 such as blue (step S172). The third control unit 71 displays the time output from the clock unit 78 on the display unit 74 and also displays information related to the time including the remaining storable time of the hard disk and the elapsed time from the start of reproduction (step S173).

  The tuner 1 receives the first operation data from the remote controller 3 as described in the first embodiment (step S174). The tuner 1 outputs the first operation data to the recorder 7 (step S175). The 3rd control part 71 of the recorder 7 receives the 1st operation data output via the CEC line 42 (step S176). Note that before the tuner 1 transmits information to the recorder 7 or the liquid crystal display 2, whether or not devices are connected to each other, confirmation of the state of the devices, and the like are performed in advance. The third control unit 71 stops the hard disk 76H and the hard disk drive control unit 762 to shift from the on state to the standby state (step S177). The third control unit 71 stops displaying the time displayed on the display unit 74 (step S178).

  The third control unit 71 turns on the first LED 721 and turns off the second LED 722 (step S179). Note that the first LED 721 may be turned off in order to further save power. The third control unit 71 can still accept the operation signal input from the input unit 73, the operation signal received by the reception unit 76, and the CEC command output via the CEC line 42 even in the standby state. As a result, not only the tuner 1 and the liquid crystal display 2 but also the overall power saving including the audio amplifier 8, the LED lamp 9 and the recorder 7 can be realized, and various light source controls can effectively produce image data. It becomes possible.

  The tuner 1 receives the second operation data from the remote controller 3 as described in the first embodiment (step S181). The tuner 1 outputs the received second operation data to the recorder 7 via the CEC line 42 (step S182). The recorder 7 receives the second operation data (step S183). The third control unit 71 activates the hard disk 76H and the hard disk drive control unit 762 again (step S184). The third control unit 71 turns off the first LED 721 and turns on the second LED 722 (step S185). The third control unit 71 displays the time output from the clock unit 78 on the display unit 74 and also displays information related to the time including the remaining storable time of the hard disk and the elapsed time from the start of reproduction (step S186).

  The third embodiment is configured as described above, and the other configurations and operations are the same as those of the first and second embodiments. Therefore, the corresponding parts are denoted by the same reference numerals and detailed description thereof is omitted. To do.

Embodiment 4
The fourth embodiment relates to a process in the case where the recording reservation time is reached while displaying image data. FIG. 19 is a block diagram showing a hardware configuration of the recorder 7 according to the fourth embodiment. In addition to the configuration of the third embodiment, the storage unit 75 is provided with a recording reservation file 751 for storing a program recording date and time and a channel. Hereinafter, the video data storage process based on the reservation when the image data described in the first embodiment is displayed on the liquid crystal display 2 will be described with reference to a flowchart.

  FIG. 20 is a flowchart showing the procedure of the recording reservation process. The user performs the desired date and time of recording (including the start date and time and the end date and time) and the channel to the tuner 1 or the recorder 7 by EPG or the like as with the viewing reservation. In this embodiment, the recorder 7 will be described as accepting a recording reservation. The third control unit 71 receives the recording date and time and the channel input via the input unit 73 or the receiving unit 76 (step S201). The third control unit 71 stores the recording date and time and the channel in the recording reservation file 751 (step S202). In the present embodiment, it is assumed that the video data storage destination related to the recording reservation is the video file 761 in the hard disk 76H.

  The tuner 1 outputs the first operation data to the liquid crystal display 2 as described in step S73 of the first embodiment and step S175 of the third embodiment, and outputs a standby signal to the recorder 7 (step S203). As a result, the image data is displayed on the display unit 24 of the liquid crystal display 2. The recorder 7 shifts to a standby state. In this situation, the third control unit 71 of the recorder 7 refers to the output of the clock unit 78 and determines whether or not the recording date / time has been reached (step S204). When it is determined that the recording date / time has not been reached (NO in step S204), the third control unit 71 waits until the recording date / time is reached.

  On the other hand, when it is determined that the recording date / time has been reached (YES in step S204), the third control unit 71 activates the hard disk 76H and the hard disk drive control unit 762 (step S205). The recorder 7 receives the video data transmitted from the tuner 1 via the signal receiving unit 792 (step S206). The third control unit 71 stores the video data in the video file 761 (step S207). As a result, the recorder 7 shifts to the on state, but the liquid crystal display 2 still displays image data that functions as a picture.

  Therefore, the third control unit 71 continues to turn off the display unit 74 (step S208) and does not display the remaining time and the like. Further, the third control unit 71 continues to turn on the first LED 721 and turn off the second LED 722 (step S209). Note that both the first LED 721 and the second LED 722 may be turned off. As a result, even when the reservation based on the reserved recording is started, when the image data is displayed on the liquid crystal display 2, it is possible to reduce the unnecessary light source and thereby improve the power saving and the aesthetics. It becomes.

  The fourth embodiment is configured as described above, and the other configurations and operations are the same as those of the first to third embodiments. Therefore, the corresponding parts are denoted by the same reference numerals and detailed description thereof is omitted. To do.

Embodiment 5
The fifth embodiment relates to a process for selecting image data to be displayed. FIG. 21 is a block diagram showing a hardware configuration of the liquid crystal display 2 according to the fifth embodiment. The storage unit 25 is further provided with a selection screen file 253. The receiving unit 16 of the tuner 1 receives operation data (hereinafter referred to as third operation data) related to a display request for selecting image data from the remote controller 3. The third operation data is transmitted to the tuner 1 by a user operation of a menu button provided on the remote controller 3, for example. The first control unit 11 of the tuner 1 outputs the third operation data to the liquid crystal display 2 via the CEC line 42.

  The second control unit 21 of the liquid crystal display 2 receives the third operation data. The second control unit 21 reads out the selection screen from the selection screen file 253 with the reception of the third operation data as a trigger, and displays it on the display unit 24. FIG. 22 is an explanatory diagram showing a display image of the selection screen. The display unit 24 includes a plurality of candidate image data thumbnails 241 to 246 (hereinafter, represented by a thumbnail S in some cases) stored in the image data file 251 and check boxes 241c to 246c (hereinafter, check boxes in some cases). and the end button 247 and the like are displayed. FIG. 22 further shows a part of the operation button group of the remote controller 3. The remote control 3 is provided with an up direction button 334, a right direction button 335, a down direction button 336, a left direction button 337, an enter button 338, and a menu button 339 as operation direction buttons 330.

  The user operates a cursor 248 for specifying image data desired to be selected based on the operation direction button 330 of the remote controller 3. Then, the image data desired to be displayed matches the cursor 248, and the enter button 338 is operated. FIG. 23 is an explanatory diagram showing a record layout of the image data file 251. The image data file 251 includes an image ID field, an image file name field, an image data field, a thumbnail data field, a display position field, a display flag field, and the like. The image ID field stores a unique ID for specifying a plurality of image data. In this example, description will be made assuming that there are six candidate image data. Note that the storage content of the image data file 251 is merely an example. If the relationship between the data is maintained, free data may be provided according to the design.

  In the image file name field, a file name of image data is stored in association with the image ID. In the image data field, image data in JPEG format is stored in association with the image ID, and similarly, thumbnail data that is a reduced image of each image data is stored in the thumbnail data field. In the display position field, coordinate values, which are position information when displaying the thumbnail S of each image data on the selection screen, are stored. In the example of FIG. 22, the upper left of the display unit 24 is the xy coordinate origin (0, 0), the right direction is the x-axis positive direction, and the lower direction is the y-axis positive direction.

  Each image data is displayed on the display unit 24 in accordance with the coordinate values stored in the image data file 251. For example, the thumbnail 242 is displayed at the position of the coordinate value (1, 0). In the present embodiment, the example in which the thumbnails S are displayed in a grid pattern has been described. However, the thumbnails may be displayed in one vertical row or one horizontal row. When the selection screen is displayed, the thumbnail 241 at the origin coordinate (0, 0) is selected (specified) by the cursor 248. The user moves the cursor 248 by operating the operation direction button 330 of the remote controller 3. The receiving unit 16 of the tuner 1 receives the first command regarding the operation direction transmitted from the remote controller 3, that is, the upper command based on the operation of the up button 334, the right command based on the operation of the right button 335, and the operation of the down button 336. And a left command based on the operation of the left direction button 337 are received. The first control unit 11 of the tuner 1 outputs the received first commands to the second control unit 21 in order of reception.

  The second control unit 21 moves the cursor 248 from the origin (0, 0) according to the first command, and specifies the image data desired to be displayed by the cursor 248. When the enter button 338 is operated from the remote controller 3, the second command related to the selection process is transmitted to the receiver 16 of the tuner 1. The first control unit 11 of the tuner 1 outputs the received second command to the second control unit 21 via the CEC line 42. When receiving the second command, the second control unit 21 writes a check mark in the check box c of the thumbnail S corresponding to the cursor 248 and sets a flag in the display flag field of the image data file 251. In the example of FIG. 22, the check box 242c of the thumbnail 242 and the check box 243c of the thumbnail 243 are selected.

  When the check is described in the check box c and the second command is further received, the second control unit 21 deletes the description of the check and deletes the display flag in the display flag field. When the cursor 248 moves to the end button 247 of the coordinate value (0, 2) based on the first command and the end button 247 is selected based on the second command, the second control unit 21 closes the selection screen. . When receiving the first operation data, the second control unit 21 reads the image data stored in the image data file 251 and set with the display flag, and outputs the read image data to the display unit 24. If there are a plurality of image data, they may be displayed sequentially at regular intervals.

  In the above hardware configuration, image data selection processing will be described using a flowchart. 24 to 27 are flowcharts showing the procedure of image data selection processing. The control unit 31 of the remote controller 3 accepts a selection screen display request based on the operation of the menu button 339 (step S241). The control unit 31 transmits the third operation data, which is a selection screen display request, to the tuner 1 via the transmission unit 36 (step S242). The receiving unit 16 of the tuner 1 receives the third operation data (step S243). The first control unit 11 of the tuner 1 outputs the third operation data to the liquid crystal display 2 via the CEC line 42 (step S244).

  The second control unit 21 of the liquid crystal display 2 receives the third operation data (step S245). The second control unit 21 reads the selection screen from the selection screen file 253 (Step S246). The second control unit 21 refers to the thumbnail S and the display position stored in the image data file 251 and displays a selection screen as shown in FIG. 22 (step S247). The second control unit 21 displays the cursor 248 in the check box 241c for the origin coordinates on the selection screen (step S248). Since the tuner 1 merely relays the first command and the second command and cannot recognize which coordinate the cursor has selected, the initial position is the origin coordinate.

  The control unit 31 of the remote controller 3 accepts an operation of the operation direction button 330 (step S249). Each time the control unit 31 receives an input from the operation direction button 330, the control unit 31 transmits a first command related to the operation direction indicating the up, down, right, or left direction to the tuner 1 via the transmission unit 36 (step S251). The tuner 1 receives the first command via the receiving unit 16 (step S252). The first control unit 11 of the tuner 1 sequentially outputs the first command to the liquid crystal display 2 via the CEC line 42 (step S253). The second control unit 21 of the liquid crystal display 2 receives the first command sequentially output (step S254), and moves the cursor 248 according to the first command (step S255). The cursor 248 selects image data desired to be displayed.

  The second control unit 21 stores the coordinate value of the movement destination of the cursor 248, that is, the coordinate value of the selected thumbnail S in the storage unit 25 (step S256). The control unit 31 of the remote controller 3 accepts an input from the enter button 338 (step S257). The control unit 31 transmits a second command indicating the selection process of the thumbnail S to the tuner 1 via the transmission unit 36 (step S258). The tuner 1 receives the second command via the receiving unit 16 (step S259). The first control unit 11 outputs the received second command to the liquid crystal display 2 via the CEC line 42 (step S261).

  The second control unit 21 of the liquid crystal display 2 receives the second command (step S262). The second control unit 21 determines whether or not the end button 247 shown in FIG. 22 is selected based on the first command and the second command (step S263). When the second control unit 21 determines that the end button 247 is not selected (NO in step S263), the second control unit 21 associates the display flag with the coordinate value stored in step S256, that is, in association with the selected thumbnail S. The image data file 251 is set (step S264). In this case, the second control unit 21 describes a check mark in the check box c on the selection screen. The process again proceeds to step S249 and the above processing is repeated.

  If the second control unit 21 determines that the end button 247 has been selected (YES in step S263), the second control unit 21 closes the selection screen (step S265). Thereafter, as described in the first embodiment, the remote controller 3 accepts the first operation data associated with the operation of the picture key 332 (step S266). The control unit 31 of the remote controller 3 transmits the received first operation data to the tuner 1 (step S267). The first control unit 11 of the tuner 1 receives the first operation data (step S268). The first control unit 11 of the tuner 1 outputs the first operation data to the liquid crystal display 2 via the CEC line 42 (step S269).

  The second control unit 21 of the liquid crystal display 2 receives the first operation data (step S271). The second control unit 21 of the liquid crystal display 2 reads the image data in which the display flag is set from the image data file 251 (step S272). The second control unit 21 displays the read image data on the display unit 24 (step S273). As described in the first embodiment, after the output of the first operation data, the tuner 1 shifts to the standby state, and the image data display process is performed by the liquid crystal display 2 alone. As in the present embodiment, image data selection and display processing are performed on the liquid crystal display 2, and the processing in the tuner 1 is shifted to the standby state only when the first command and the second command are received and output. Thus, it is possible to save power when displaying image data. In the present embodiment, the first command and the second command are output to the liquid crystal display 2 every time the operation is performed. However, information for specifying image data to be displayed is sent from the tuner 1 to the liquid crystal display 2 after step S265. You may send to all at once. For example, an ID is attached to the image data, and the user inputs the ID of the image data desired to be displayed by the remote controller 3. The first control unit 11 of the tuner 1 accepts one or more IDs as information for specifying image data to be displayed. Then, after closing the selection screen of the liquid crystal display 2, the first control unit 11 of the tuner 1 outputs the received ID to the liquid crystal display 2 via the CEC line 42. The second control unit 21 of the liquid crystal display 2 sets a display flag in the image data corresponding to the received ID. As a result, the amount of communication between the tuner 1 and the liquid crystal display 2 can be reduced.

  The fifth embodiment has the above-described configuration, and the other configurations and operations are the same as those of the first to fourth embodiments. Therefore, the corresponding parts are denoted by the same reference numerals and detailed description thereof is omitted. To do.

Note that the processes in steps S301 and S302 are the same as steps S73 and S74 described in the first embodiment, and thus detailed description thereof is omitted.

  The second control unit 21 determines whether or not the USB memory 6 is attached to the USB slot 211 (step S303). If the second control unit 21 determines that the USB memory 6 is attached (YES in step S303), the second control unit 21 determines whether image data exists in the image data file 65 of the USB memory 6 (step S304). If the second control unit 21 determines that image data exists (YES in step S304), the second control unit 21 reads the image data in the image data file 65 of the USB memory 6 (step S305). The second control unit 21 displays the read image data on the display unit 24 (step S306).

  The second control unit 21 determines that the USB memory 6 is not attached (NO in step S303), or determines that no image data exists in the image data file 65 of the USB memory 6 (in step S304). NO), it is determined whether or not a display flag is set in the image data file 251 of the storage unit 25 (step S307). If the second control unit 21 determines that the display flag is set (YES in step S307), it reads the image data for which the display flag is set (step S308). The second control unit 21 displays the read image data on the display unit 24 (step S309).

  On the other hand, if the second control unit 21 determines that no display flag is set (NO in step S307), the second control unit 21 reads a warning image from the warning image file 254 (step S311).

Embodiment 7
In the fourth embodiment, the recording date and time and the reception of the channel are executed on the recorder 14 side, but may be executed in the tuner 1. 32 and 33 are flowcharts showing the procedure of the recording reservation process according to the seventh embodiment. When the user makes a recording reservation, the remote controller 3 transmits a signal indicating that the recording reservation is started to the tuner 1 via the transmission unit 36. The first control unit 11 of the tuner 1 receives a signal to start recording reservation via the receiving unit 16 (step S321). The first control unit 11 outputs the recording reservation start information to the liquid crystal display 2 through the CEC line 42 (step S322).

  Based on the reception of the recording reservation start information, the second control unit 21 of the liquid crystal display 2 displays the recording reservation screen stored in advance in the storage unit 25 on the display unit 24 (step S323). A user operates the remote controller 3 while referring to the screen displayed on the liquid crystal display 2 to input a date and a channel desired to be recorded. The control unit 31 of the remote controller 3 transmits the input recording date and time and channel to the tuner 1. The first control unit 11 of the tuner 1 receives the recording date and time and the channel via the receiving unit 16 (step S324).

  The first control unit 11 stores the recording date and time and the channel in the storage unit 15 (step S325). The first control unit 11 outputs information indicating that the recording reservation setting is completed to the liquid crystal display 2 via the CEC line 42 (step S326). When the second control unit 21 of the liquid crystal display 2 receives the information, the second control unit 21 turns on an LED (not shown) as a light emitting unit indicating that the recording reservation has been set (step S327).

  Thereafter, the first control unit 11 of the tuner 1 outputs the first operation data to the liquid crystal display 2 as described in step S73 of the first embodiment and step S175 of the third embodiment (step S328). Further, the first controller 11 outputs a standby signal to the recorder 7 (step S329). The recorder 7 shifts to the standby state. The second control unit 21 of the liquid crystal display 2 turns off the LED indicating that the above-described lighting recording reservation is set, triggered by the reception of the first operation data (step S331). The second control unit 21 of the liquid crystal display 2 displays the image data on the display unit 24 (step S332). Thereby, even when image data is displayed, it is possible to reduce glare caused by the LEDs. Under this situation, the first control unit 11 of the tuner 1 refers to the output of the clock unit 18 and determines whether or not the recording date / time has been reached (step S333). If the first control unit 11 determines that the recording date / time has not been reached (NO in step S333), the first control unit 11 waits until the recording date / time is reached.

  On the other hand, if the first control unit 11 determines that the recording date / time has been reached (YES in step S333), the first control unit 11 outputs a signal to the recorder 7 that recording should be started via the CEC line 42 (step S334). ). The 3rd control part 71 of the recorder 7 starts the hard disk 76H and the hard disk drive control part 762 (step S335). Since the subsequent processing is the same as that after step S206 of the fourth embodiment, detailed description thereof is omitted.

  The seventh embodiment has the above-described configuration, and the other configurations and operations are the same as those of the first to sixth embodiments. Therefore, the corresponding parts are denoted by the same reference numerals and detailed description thereof is omitted. To do.

Embodiment 8 relates to a mode for changing the size of image data. FIG. 34 is a block diagram showing a hardware configuration of the liquid crystal display 2 according to the eighth embodiment. The storage unit 25 of the liquid crystal display 2 further stores a setting screen file 255 and a size table 256. The setting screen file 255 stores screen data read when setting the size, display time, display time per image data, and the like when displaying image data on the display unit 24. FIG. 35 is an explanatory diagram showing an image of the setting screen. The second control unit 21 reads the setting screen from the setting screen file 255 and outputs it to the display unit 24.

  As shown in FIG. 35, a screen for selecting a size for displaying image data is displayed. In the selection screen, a check box 261a for large size, a check box 261b for medium size, and a check box 261c for small size are displayed. The large size is selected when image data is displayed over the entire pixel area of the display unit 24. For example, the number of pixels of the display unit 24 is 1920 in the horizontal direction and 1080 in the vertical direction. In order to save power, the check box 261b corresponding to the medium size or the check box 261c related to the small size is selected.

  For example, during the size, the image data is displayed using 1366 pixels in the horizontal direction and 768 pixels in the vertical direction among all the pixels 1920 × 1080 of the display unit 24. In the small size, image data is displayed using 640 pixels in the horizontal direction and 480 pixels in the vertical direction among all the pixels 1920 × 1080 of the display unit 24. The user uses the remote controller 3 to select one of the check box 261a related to the large size, the check box 261b related to the medium size, or the check box 261c related to the small size. In the present embodiment, the sizes are large, medium, and small. However, this is only an example, and the present invention is not limited to this. The number of vertical and horizontal pixels is only an example. In the display time input box 262, the total display time for displaying the image data is input.

  In the example of FIG. 35, 2 hours are input. In the display time input box 263 per sheet, a time for displaying one image data is input. When the time input to the display time input box 263 per sheet has elapsed, the next image is output to the display unit 24. When the user finishes inputting the size, display time, and display time per sheet, the user operates the end button 247. The input information is stored in the storage unit 25. When displaying the image data, the second control unit 21 refers to the output of the clock unit 28 and sequentially displays the image data according to the display time per sheet stored in the storage unit 25. Further, the second control unit 21 refers to the output of the clock unit 28 and the display time stored in the storage unit 25 and stops outputting image data to the display unit 24 after the comprehensive display time has elapsed after receiving the first operation data. And transition to the standby state. The control based on the size will be described later.

  FIG. 36 is an explanatory diagram showing a record layout of the size table 256. The size table 256 includes a size field, a pixel field, and an unlit LED information field. The size field stores the size at which the image data is displayed on the display unit 24. In the pixel field, a pixel for displaying image data is stored in association with the size. In the off LED information field, information on the LED backlight 210 to be extinguished among the LED backlights 210 which are a plurality of light emitting elements dispersedly arranged to irradiate the image data on the back surface of the display unit 24 in association with the size. Is remembered. For example, an ID for specifying the LED backlight 210 to be turned off is stored. In the above example, when the size is large, the LED backlight 210 that is turned off to use all the pixels is stored as 0. In this case, the signal processing unit 29 turns on all of the plurality of LED backlights 210. On the other hand, since the area for displaying the image data is small when the size is medium, a plurality of IDs of the LED backlight 210 to be turned off are stored. In this case, the signal processing unit 29 turns off the LED backlight 210 corresponding to the ID of the LED backlight 210 to be turned off in the size among the plurality of LED backlights 210. Further, when the size is small, the area for displaying the image data is further reduced, and thus a plurality of IDs of the LED backlights 210 to be turned off are stored. In this case, the signal processing unit 29 turns off the LED backlight 210 corresponding to the ID of the LED backlight 210 to be turned off according to the small size among the plurality of LED backlights 210. Of course, the ID of the LED backlight 210 to be turned on may be stored instead of the ID of the LED backlight 210 to be turned off. Hereinafter, the ID of the LED backlight 210 that is turned off is referred to as “turned-off LED information”.

  FIG. 37 and FIG. 38 are flowcharts showing the procedure of image data display size setting processing.

The user uses the operation direction button 330 of the remote controller 3 to select one of the check box 261a for the large size, the check box 261b for the medium size, or the check box 261c for the small size. Finally, the end button 247 is selected using the operation direction button 330 and the enter button 338 is operated. The control unit 31 of the remote controller 3 transmits the size of the image data to the tuner 1 via the transmission unit 36. The first control unit 11 of the tuner 1 receives the size transmitted from the remote controller 3 via the receiving unit 16 (step S375).

  The first control unit 11 outputs the received size to the liquid crystal display 2 via the CEC line 42 (step S376). In the present embodiment, large, medium or small information is transmitted and received as the size information, but pixel information such as 1366 × 768 may be transmitted. The second control unit 21 of the liquid crystal display 2 receives the size output via the CEC line 42 (step S377). The second control unit 21 stores the received size in the storage unit 25 (step S378).

  The first control unit 11 of the tuner 1 outputs the first operation data for displaying the image data to the liquid crystal display 2 through the CEC line 42 as described in the first embodiment (step S379). The second control unit 21 of the liquid crystal display 2 receives the first operation data output via the CEC line 42. The second control unit 21 reads out the pixel and extinguished LED information corresponding to the size stored in the storage unit 25 from the size table 256 with the reception of the first operation data as a trigger (step S381). The second control unit 21 outputs the pixel and extinguished LED information to the signal processing unit 29 (step S382). The second control unit 21 reads image data to be displayed from the image data file 251 (step S383). The signal processing unit 29 displays the image data on the display unit 24 after reducing the image data as it is or according to the output size as it is (step S384). Further, the signal processing unit 29 turns off the LED backlight 210 in accordance with the output off LED information (step S385). Accordingly, a part of the LED backlight 210 unnecessary for displaying the image data is turned off depending on the size setting of the user, so that further power saving can be achieved while displaying the image data.
