When the video display device is a television device or the like placed in the living room, the users are not limited, and it is conceivable that a plurality of users share the video display device. When there are a plurality of users and the preference for setting such as image quality is different for each user, each user allows the setting that does not suit his / her preference and uses the image display device, or the image display device. It cannot be said that the usability is good because it is necessary to select either the setting of the image quality or the like every time the user is used.

In the above situation, it is desirable that the video display device identifies each user and automatically changes the setting according to each of the identified users. However, the above-mentioned Patent Document 1 does not give consideration to the above-mentioned problem. Further, even when the video display device has a recording function of a digital broadcast program and the like and displays a list of recorded programs, the video display device identifies each user and each of the identified users. If the display method of the content corresponding to the user is automatically set, the video display device becomes more convenient to use.

An object of the present invention is to consider the above problems and to provide a more convenient image display device even when a plurality of users share the same.

As a means for solving the above-mentioned problems, in the present invention, for example, a video display device having the configuration described in the claims may be used.

For example, a video display device capable of displaying content communicates with a tuner that receives the content of a broadcast program via digital broadcasting and a mobile information terminal via a home network, and the content via an external network. The communication unit, the content received by the tuner, or the display unit capable of displaying the content acquired by the communication unit, and the operation person information about the operating person of the mobile information terminal from the mobile information terminal. It is provided with a storage unit, a controller, and a storage unit that acquires and stores information via the above and stores the setting contents for the setting items of the video display device and the operating person information related to the operating person of the mobile information terminal in association with each other. Then, the controller compares the operating person information about the new operating person acquired from the new mobile information terminal via the communication unit with the operating person information about the operating person stored in the storage unit, and compares the operating person information. When the identification process is performed and the identification process identifies that the operating person information relating to the new operating person is the operating person corresponding to the operating person information stored in the storage unit, the operating person of the operating person is identified. The first control for displaying the settings based on the setting contents for the setting items of the video display device corresponding to the information is performed, and the operating person information regarding the new operating person is stored in the storage unit by the identification process. When it is identified that the operating person does not correspond to the operating person information, the second control for performing the setting display in which the setting contents for the setting items of the video display device are set as standard settings may be performed.

By using the technique of the present invention, it is possible to provide a more convenient image display device even when it is shared by a plurality of users.

It is assumed that the video display device 100 can realize various new functions by deploying and executing the new application stored in the other information storage area 133 on the RAM 104.

The storage unit 130 needs to hold the stored information even when the power is not supplied to the video display device 100. Therefore, for example, devices such as flash ROMs, SSDs (Solid State Drives), and HDDs are used.

The video input unit 141 is a camera that inputs image data of the surroundings and an object by converting the light input from the lens into an electric signal. The video input unit 141 may be built in the video display device 100 and have an integrated configuration, or a separate camera may be connected to a USB interface or the like described later. The operator identification unit 142 identifies a person who operates the video display device 100 or a terminal device used for operating the video display device 100 (hereinafter, the person and the terminal device are collectively referred to as an operator). (Hereinafter referred to as an operator identification process). The details of the operator identification process will be described later. Although the operator identification unit 142 is described as an independent configuration in FIG. 1, the main control unit 101 may operate so as to realize the same function with the RAM 104 as a work area. The voice input unit 143 is, for example, a microphone, which converts a user's voice or the like into voice data and inputs it. The audio input unit 143 may be built in the video display device 100 and have an integrated configuration, or may be a separate microphone connected to a USB interface or the like described later.

The audio input / output unit 152 and the video input / output unit 153 input the audio signal / video signal from the external audio / video output device and output the audio signal / video signal to the external audio / video input device. When the video display device 100 is an HDD recorder, a BD recorder, or an STB, a monitor device may be connected to the audio input / output unit 152 and the video input / output unit 153. The USB interface 154 connects a USB device such as a keyboard or memory cards. When the video display device 100 does not have a built-in recording / playback function and records a digital broadcast program on an externally connected HDD device or the like, the HDD device or the like may be connected to the USB interface 154.

The operation unit 160 is an instruction input unit for inputting operation instructions to the video display device 100. In this embodiment, the operation unit 160 includes an operation key 161 in which button switches are arranged and a remote control reception unit 162 for receiving an infrared signal from a remote controller. Will be done. The image display device 100 may be operated by using a touch panel arranged so as to be superimposed on the display unit 121 instead of the operation key 161. Both may be used together. The video display device 100 may be operated by using a keyboard or the like connected to the USB interface 154. The video display device 100 may be operated using a mobile information terminal, a PC, or the like connected to the network via the LAN interface 151.

The configuration example of the image display device 100 shown in FIG. 1 includes configurations that are not essential to the present invention, such as the external interface 150, but the effects of the present invention are not impaired even without these configurations. Further, a communication unit that enables mobile telephone network communication, a mail transmission / reception unit, an acceleration sensor, a gyro sensor, a geomagnetic sensor, a GPS (Global Positioning System) receiver, and the like may be further included.

The video display device 100 of this embodiment has a function of performing an operator identification process under the control of an operator identification unit 142 and automatically changing settings according to the identified operator.

An example in which the operator identification process is performed by inputting an image of a person who operates the video display device 100 will be described below.

For example, as shown in FIG. 2, when the person A (400a) is an operator who operates the video display device 100 using the remote controller 200, first, the video input unit 141 is the operator of the video display device 100. The image of the person A (400a) is input. Further, the operator identification unit 142 extracts face information (operator information) from the input image, and the user of the image display device 100 stores the extracted face information in advance in the individual information storage area 131. Performs face recognition processing to compare with the saved face information. When the person A (400a) has already registered his / her face information in the individual information storage area 131, the operator of the image display device 100 is the person A (400a) in the operator identification unit 142 by the face recognition process. It becomes possible to identify that there is.

Alternatively, the video input unit 141 inputs an image of the person A (400a) who is the operator of the video display device 100, and the operator identification unit 142 further inputs the gesture information of the person A (400a) from the input image. The operator information) is extracted, and the gesture recognition process is performed in which the extracted gesture information is compared with the gesture information stored in advance in the individual information storage area 131 by the user of the video display device 100. When the person A (400a) has already registered his / her gesture information in the individual information storage area 131, the operator of the image display device 100 is the person A (400a) in the operator identification unit 142 by the gesture recognition process. It becomes possible to identify that.

When the operator identification process is performed using the gesture recognition process, it is preferable to configure the device so as to recognize that the gesture for the operator identification process has been performed after the predetermined operation. Specifically, for example, when the remote controller 200 is provided with the "gesture input" button, the gesture recognition for the operator identification process may be performed after the "gesture input" button is pressed. Alternatively, after the operator utters a predetermined keyword (for example, "gesture input start", etc.) and the video display device 100 recognizes the keyword, the operator performs a gesture for the operator identification process. , This may be recognized by the image display device 100. By doing so, the recognition efficiency in the gesture recognition process can be improved.

Further, as shown in FIG. 3, when there are a plurality of persons (three persons A (400a), B (400b), and C (400c)) who view the image display device 100, the image input unit 141 is used. The images of the plurality of persons are input, and the infrared light output by the remote controller transmitter 240 of the remote controller 200 is detected. In this way, the operator identification unit 142 extracts the face image of the plurality of persons and the human body position connected to the face image from the input image, and further extracts the extracted face image and the human body position and the detection. By analyzing the positional relationship of the infrared light, it is possible to identify the person A (400a) holding the remote controller 200 as the operator of the image display device 100. Further, the operator identification unit 142 identifies that the operator of the video display device 100 is the person A (400a) by performing face recognition processing or gesture recognition processing on the specified person A (400a). It becomes possible to do.

As for the face recognition process and the gesture recognition process, existing known techniques may be used, and therefore detailed description thereof will be omitted.

Further, an example in which the operator identification process is performed by inputting the sound emitted by the person who operates the video display device 100 will be described below.

For example, as shown in FIG. 4, when the person A (400a) is an operator who operates the video display device 100 using the remote controller 200, first, the audio input unit 143 is the operator of the video display device 100. The voice emitted by the person A (400a) is input. Further, the operator identification unit 142 extracts predetermined keyword information (operator information) from the input voice, and the user of the video display device 100 previously displays the extracted keyword information in the individual information storage area 131. Performs voice recognition processing to compare with the stored keyword information. When the keyword information determined by the person A (400a) is registered in the individual information storage area 131, the operator identification unit 142 uses the person A (400a) as the operator of the video display device 100 by the voice recognition process. It becomes possible to identify that there is.

The keyword information may be words such as "I will operate", "start operation", "start", the name of a person or pet, or "mountain" or "river". It may be the word. Further, in the voice recognition process, if the keywords match, the voice qualities and the like do not have to match.

Alternatively, the voice input unit 143 inputs the voice emitted by the person A (400a) who is the operator of the video display device 100, and the operator identification unit 142 further performs voiceprint analysis on the input voice. The voiceprint information (operator information) is extracted by the user, and the voiceprint analysis process is performed to compare the extracted voiceprint information with the voiceprint information stored in advance in the individual information storage area 131 by the user of the image display device 100. .. When the person A (400a) has already registered his / her voiceprint information in the individual information storage area 131, the operator of the image display device 100 is the person A (400a) in the operator identification unit 142 by the voiceprint analysis process. It becomes possible to identify that.

The voice used for the voiceprint analysis process may be any word or word, but if a predetermined word or word (for example, "I operate") or word is used, the voiceprint analysis process can be performed. It is possible to improve the analysis efficiency in.

Further, with respect to the voice recognition process and the voiceprint analysis process, existing known techniques may be used, and therefore detailed description thereof will be omitted.

When the person who operates the video display device 100 is a person whose information is stored in the individual information storage area 131 in advance, the person operates the video display device 100 and the person operates the video display device 100. The OSD display indicating that 100 operations are being performed may be performed.

For example, as shown in FIG. 5, when the person A (400a) whose operator information is stored in the individual information storage area 131 in advance is identified as the operator of the video display device 100 by the operator identification process. When the person A (400a) operates the image display device 100, the OSD display 121-1 clearly indicating that the image display device 100 is operated by the person A (400a) is displayed on the display unit 121. To do so. In this way, it is possible to clarify who is operating the video display device 100, especially when there are a plurality of people who are viewing the video display device 100.

The timing at which the video display device 100 displays the OSD display 121-1 may be all the timings at which the operation of the video display device 100 is performed, or a predetermined operation (of the video display device 100). It may be only the timing when the operation related to the setting change, etc.) is performed.

The operator identification process may be performed only at a predetermined timing (when the power is turned on, when returning from the sleep state, etc.). Alternatively, it may be performed every time the video display device 100 receives a control command from the remote controller 200, or may be performed periodically at predetermined time intervals.

Further, in recent years, a technique has become common in which a portable information terminal such as a smart phone or a tablet terminal is used as a terminal device for operating a television device for receiving digital broadcasts by operating a dedicated application.

When the above technology is applied and the operator identification process is performed by inputting the sound output from a portable information terminal (terminal device operating the video display device 100) owned by a person who operates the video display device 100. An example will be described below.

For example, as shown in FIG. 6, the mobile information terminal 300 has a function of transmitting an infrared signal for operating the video display device 100 in place of the remote control 200, and the person A (400a) is the mobile information terminal. In the case of an operator who operates the video display device 100 using the 300, first, the voice input unit 143 causes the mobile information terminal 300 owned by the person A (400a) who is the operator of the video display device 100 to output the signal. Input the sound. Further, the operator identification unit 142 digitally samples the input sound and converts it into sound data (operator information), and the user of the video display device 100 stores the sound data in advance in the individual information storage area 131. Performs sound source analysis processing to compare with the sound data that has been set. When the sound data selected by the person A (400a) is registered in the individual information storage area 131, the operator of the image display device 100 is the person A (400a) in the operator identification unit 142 by the sound source analysis process. It becomes possible to identify that there is.

As the sound data, animal sounds, musical instrument performance sounds, popular songs, and the like may be used. Further, with respect to the sound source analysis process, an existing known technique may be used, and therefore detailed description thereof will be omitted.

Further, an example in which the operator identification process is performed by communication with a terminal device such as a personal digital assistant that operates the video display device 100 will be described below.

For example, as shown in FIG. 7, when the mobile information terminal 300 owned by the person A (400a) is the operator of the video display device 100, the mobile information terminal 300 is controlled in response to the operation of the person A (400a). The command and the operator information are transmitted to the video display device 100 via the router device 360. On the other hand, in the video display device 100, the main control unit 101 interprets and executes the transmitted control command, and at the same time, the operator identification unit 142 performs the operator identification process using the transmitted operator information. To do so.

Specifically, when the mobile information terminal 300 of this embodiment has a configuration as shown in the block diagram in FIG. 8, the person A (400a) is the mobile information terminal 300 on which the video display device control application is operating. By operating the operation unit 340 (communication has been established in advance by the authentication process with the video display device 100), the main control unit 301 first converts the operation into a control command for the video display device 100. Next, the main control unit 301 superimposes the operator information for identifying the mobile information terminal 300 as the operator of the video display device 100 in the operator identification process of the operator identification unit 142 on the control command, and LAN. It is transmitted from the communication unit 352.

The video display device 100 receives the superposed control command of the operator information transmitted via the router device 360 on the LAN interface 151, and the main control unit 101 interprets and executes the received control command. .. At the same time, the operator identification unit 142 extracts the operator information from the superposed control command of the received operator information and compares it with the operator information stored in advance in the individual information storage area 131. conduct. When the operator information of the mobile information terminal 300 is registered in the individual information storage area 131, the operator identification unit 142 identifies that the operator of the video display device 100 is the mobile information terminal 300 by the comparison process. It becomes possible.

The operator information may be data such as a product name or model number of the mobile information terminal 300, or may be data such as a production number or a serial number. When the mobile information terminal 300 has a telephone communication function, it may be a telephone number used for the telephone communication function or other unique number data associated with the telephone number. It may be a keyword, a passcode, an owner number, or the like arbitrarily determined by the owner of the mobile information terminal 300. Further, the operator information may be stored in the ROM 303, the RAM 304, or the storage unit 310, or may be stored in a memory card (not shown) connected to the memory interface 341. Is also good. It may be used as operator information by downloading the owner data stored in association with the telephone number or the unique number to a data server or the like on the Internet.

Further, the mobile information terminal 300 has a user authentication function for authenticating the owner of the mobile information terminal 300, and the operator information is obtained only when the owner of the mobile information terminal 300 is successfully authenticated by the user authentication function. It is desirable to enable (transmit).

The process of authenticating the owner of the mobile information terminal 300 may be performed by inputting a password or a passcode to the operation unit 340. Alternatively, face authentication by inputting a face image to the video input unit 322 or other image authentication may be performed. It may be performed by voice recognition or voiceprint analysis by voice input to the voice input unit 324, or sound source analysis by inputting musical instrument performance sounds or popular songs. Alternatively, fingerprint discrimination may be performed by fingerprint input to the fingerprint input unit (not shown). It may be performed by biometric authentication for discriminating patterns such as palm prints, irises, and veins. Touch authentication may be performed by touching a predetermined position of a touch panel arranged on the operation unit 340 in a predetermined order.

By providing the mobile information terminal 300 with a user authentication function in this way, it is possible to prevent a third party different from the owner of the mobile information terminal 300 from using the operator information of the mobile information terminal 300. ..

When the mobile information terminal 300 is identified as the operator of the video display device 100 by the operator identification process, as shown in FIG. 9, when the video display device 100 is operated by the mobile information terminal 300. , The OSD display 121-2 indicating that the mobile information terminal 300 is operating the video display device 100 may be displayed.

Further, if the information that the owner of the mobile information terminal 300 having the operator information is the person A (400a) is further stored in the individual information storage area 131, the operator identification unit 142 can be stored. It is possible to indirectly identify that the person A (400a) is a person who is using the portable information terminal 300 which is the operator of the image display device 100.

In this case, when the mobile information terminal 300 is identified as the operator of the video display device 100 by the operator identification process and the video display device 100 is operated by the mobile information terminal 300, the person A (400a) is imaged. The OSD display 121-1 indicating that the display device 100 is being operated may be displayed.

At the timing when the video display device 100 displays the OSD display 121-2 or the OSD display 121-1, the mobile information terminal 300 transmits a control command to the video display device 100 in response to the operation of the person A (400a). It may be all timings, or it may be only the timing when a predetermined predetermined operation (operation related to setting change of the image display device 100, etc.) is performed.

The operator identification process may be performed only at predetermined predetermined timings (when the power is turned on, when returning from the sleep state, when communication between the video display device 100 and the mobile information terminal 300 is established, etc.). .. Alternatively, it may be performed every time the video display device 100 receives a control command from the mobile information terminal 300, or it may be performed periodically at predetermined time intervals. The video display device 100 may request the mobile information terminal 300 to transmit the operator information.

Next, an example in which the operator identification process is performed by storing the operator information in the remote controller 200 in advance will be described below.

For example, as shown in FIG. 10, when the person A (400a) is an operator who operates the video display device 100 by using the remote controller 200, the person A (400a) provides the operator information for identifying himself / herself. The remote controller 200 is stored in advance. Further, the remote controller 200 transmits the control command and the operator information to the video display device 100 in response to the operation of the person A (400a). On the other hand, in the video display device 100, the main control unit 101 interprets and executes the transmitted control command, and at the same time, the operator identification unit 142 performs the operator identification process using the transmitted operator information. To do so.

An example of a method for storing the operator information for causing the video display device 100 to identify the person A (400a) in the remote controller 200 in advance will be described below.

For example, when the remote controller 200 of this embodiment has a configuration as shown in the block diagram in FIG. 11, a predetermined access key (operator) predetermined by the person A (400a) and stored in the individual information storage area 131. Information) may be input from the operation unit 220 of the remote controller 200 and stored in the RAM 204. Alternatively, by bringing the mobile information terminal 300 owned by the person A (400a) close to the remote controller 200, communication between the proximity wireless communication unit 353 of the mobile information terminal 300 and the proximity wireless communication unit 252 of the remote controller 200 is established. The remote controller 200 may read the operator information of the portable information terminal 300 and store it in the RAM 204. Alternatively, a memory card 260 (or something similar to a memory card) in which predetermined identification information (operator information) stored in the individual information storage area 131 by the person A (400a) is stored in the remote controller 200. It may be connected to the memory interface 252.

When the person A (400a) operates the operation unit 220 of the remote controller 200 that stores any of the operator information by the processing, the main control unit 201 becomes a control command for controlling the image display device 100. Any of the above operator information is superimposed and transmitted as an infrared signal from the remote controller transmitter 240.

In the video display device 100, the remote control receiving unit 162 receives the control command on which the operator information is superimposed, and the main control unit 101 interprets and executes the control command. At the same time, the operator identification unit 142 extracts any of the operator information from the superposed control command of the received operator information and compares it with the operator information stored in advance in the individual information storage area 131. Perform the processing to be performed. When the operator information for the person A (400a) to identify himself / herself is registered in the individual information storage area 131 in advance, the operator identification unit 142 can be carried by the operator of the video display device 100 by the comparison process. It is possible to identify the terminal 300.

When the remote controller 200 is used by a person different from the person A (400a), the different person performs the process of storing the operator information for identifying the different person in the remote controller 200 again. .. In this way, even when a plurality of people view the video display device 100 and the remote controller 200 is shared by the plurality of people, the operator identification process can be performed.

The operator identification process may be performed every time the video display device 100 receives a control command from the remote controller 200, or the remote controller 200 may periodically perform the operator identification process at predetermined time intervals regardless of the operation of the person A (400a). It may be performed by transmitting the operator information to the video display device 100.

The example of the operator identification process has been described above with reference to the figure. The method described in the above example may be used not only alone but also in combination of a plurality of methods. Further, a method different from the above-mentioned example may be used. Examples of different methods of the operator identification process include biometric authentication processing for confirming fingerprints, palm prints, veins, irises, etc., input of a login password, and the like.

The video display device 100 of this embodiment further performs a setting change process to which the individual settings for each operator are applied according to the operator identified by the operator identification process described above. 12 and 13 are diagrams and flowcharts illustrating a setting change process performed by the video display device 100 according to the operator identified by the operator identification process.

The image display device 100 shown in FIG. 12 has the operator information of the person A (400a) and the individual settings for the person A (400a), and the operator information of the person B (400b) and the individual settings for the person B (400b). , And the operator information of the person C (400c) and the individual settings for the person C (400c) are associated with the operator information of the operator of the video display device 100 and the individual settings for the operator, and the individual information is stored. It is assumed that the area 131 is stored in advance.

In this state, when the power of the video display device 100 is turned on using a terminal device such as a remote controller or a personal digital assistant (S101), the main control unit 101 of the video display device 100 performs activation processing such as initialization of each unit. At the same time, the operator identification unit 142 performs the operator identification process (S102). The operator identification process performed in S102 may be performed by using the method described in the above example. In the operator identification process of S102, when it is confirmed that the operator has been successfully identified (S103) and that the identified operator is stored in advance as the operator of the video display device 100 (S104), that is, When the operator information of the person who operates the image display device 100 or the operator information of the terminal device used for operating the image display device 100 matches the operator information stored in the individual information storage area 131, the main control unit 101 moves. The identified individual settings for the operator are read from the individual information storage area 131 (S105), and the read individual settings are applied (S106).

For example, when the person A (400a) is identified as the operator of the video display device 100 in the series of processes from S102 to S104, the main control unit 101 displays the operator information of the person A (400a) in the individual information storage area 131. Read the associated and stored individual settings for person A (400a) and apply them. Similarly, when the person B (400b) is identified as the operator of the video display device 100, the individual settings for the person B (400b) are set, and when the person C (400c) is identified, the person C (400c) is identified. ) Is read from the individual information storage area 131 and applied.

On the other hand, when the operator is not successfully identified in the series of processes S102 to S103, or the operator is successfully identified in the series of processes S102 to S104, the operator information of the identified operator is obtained. When it is not confirmed that the information is stored in the individual information storage area 131 (for example, when the person identified by the operator identification process is the person D (400d), the operator information of the identified terminal device is the individual information storage area. When it is not stored in 131, etc.), the main control unit 101 reads the standard setting provided in the image display device 100 from the ROM 103 (S115), and applies the read standard setting (S106).

The video display device 100 of this embodiment updates the individual settings for each operator stored in the individual information storage area 131 as necessary when the power is turned off or when the operator is changed in the middle. Processing to be performed (when the processing of S105 is selected when the flowchart shown in FIG. 13 is executed), or the processing of newly storing the operator information of the new operator and the individual settings for the new operator in the individual information storage area 131. (When the process of S115 is selected when the flowchart shown in FIG. 13 is executed) is performed. FIG. 14 shows a process (FIG. 14 (A)) of updating individual settings for each operator stored in the individual information storage area 131, which is performed when the power of the video display device 100 is turned off, or a new operator. It is a flowchart explaining the process (FIG. 14B) of newly storing the operator information and the individual setting for the new operator in the individual information storage area 131.

When a control command is transmitted from a terminal device such as a remote controller or a personal digital assistant while waiting for a control command, the image display device 100 receives the control command at the remote controller receiving unit 162 or the LAN interface 151 (S201). Next, the main control unit 101 confirms whether or not the received control command is a power-off command (S202). In S202, if the control command received in S201 is not a power-off command, the video display device 100 returns to the control command standby state after the main control unit 101 executes the received control command.

On the other hand, in S202, when the control command received in S201 is a power-off command, the main control unit 101 reads and applies the individual settings for each operator or the standard settings provided in the video display device 100. , It is confirmed whether or not the setting of the image display device 100 has been changed by the operator (S203). When it is determined in S203 that the setting has been changed, the main control unit 101 updates the individual setting for each operator stored in the individual information storage area 131 (S204: for each operator). (When the process of reading and applying the individual settings has been performed), or the process of newly storing the operator information of the new operator and the individual settings for the new operator in the individual information storage area 131 (S214: video display device). (When the process of reading and applying the standard setting provided in 100 has been performed) is executed. Further, after executing the process of S204 or S214, the main control unit 101 executes the end process for turning off the power of the image display device 100 (S205).

If it is determined in S203 that the setting has not been changed, the termination process for turning off the power of the video display device 100 may be executed without executing the process of S204 or S214.

Further, when the operator of the video display device 100 is changed in the middle, first, the same processing as in S203 and S204 of FIG. 14A (processing of reading and applying individual settings for each operator is performed). (If this is the case), or the same processing as in S203 and S214 of FIG. 14B (when the processing of reading and applying the standard setting provided in the video display device 100 has been performed) is executed. After that, depending on the newly identified operator, the same processing as in S105 and S106 of FIG. 13 (when the operator information of the newly identified operator is stored in advance in the individual information storage area 131), or FIG. The same processing as in S115 and S106 of 13 (when the operator information of the newly identified operator is not stored in the individual information storage area 131) may be performed.

Through the above processing, the video display device 100 of the present embodiment can perform a setting change process for automatically applying the individual settings for the operator according to the operator identified by the operator identification process described above. It will be possible.

In the above-mentioned example, it has been described that the individual information storage area 131 of the video display device 100 stores the individual settings for each operator. However, as a different example, for example, the storage unit 310 of the mobile information terminal 300 may store the individual settings for each operator.

In this case, in the processing of the flowchart of FIG. 13, it is assumed that the operator has been successfully identified by the series of processes S102 to S104, and the operator information of the identified operator is stored in the individual information storage area 131. When confirmed, the main control unit 101 may apply the individual setting for the identified operator acquired from the storage unit 310 of the mobile information terminal 300 by communication via the LAN interface 151.

When the mobile information terminal 300 is operated to change the setting of the video display device 100, the main control unit 301 can recognize the content of the setting change made by the video display device 100. Therefore, when the individual settings for each operator are stored in the storage unit 310 of the mobile information terminal 300, the information regarding the contents of the setting changes made by the video display device 100 is acquired by communicating with the video display device 100. Without this, it is possible to perform a process of updating the individual settings for each operator or a process of newly storing the individual settings for a new operator.

However, when the image display device 100 is a display device with a touch panel such as an electronic blackboard device provided with a touch panel, the setting of the display device with the touch panel can be changed by operating the touch panel without operating the mobile information terminal 300. Is. In this case, in the process of updating the individual settings for each operator or the process of newly storing the individual settings for the new operator, the main control unit 301 is equipped with the touch panel in the process of S204 or S214 of FIG. Information on the content of the setting change made on the display device with a touch panel is acquired by communicating with the display device.

The items that can be set by the individual settings for the operator applied by the video display device 100 of the present embodiment according to the operator identified by the operator identification process will be described below with an example.

When the video display device 100 is a television device for receiving digital broadcasts, items such as image quality, sound quality, and operation mode when viewing digital broadcast programs are generally changeable according to preference. Therefore, even in the image display device 100 of the present embodiment, for example, settings related to image quality such as image brightness, black level, hue and color depth, settings related to sound quality such as strength and weakness of each sound range, and built-in frames. The operation mode of the rate conversion circuit, the brightness of the backlight, the on / off of the energy saving mode, and other settings related to the operation of the device are stored in the individual information storage area 131 as individual settings for each operator. You can do it.

In this way, the video display device 100 of the present embodiment identifies the operator by the operator identification process, and the operation is stored in the individual information storage area 131 in advance according to the identified operator. Individual settings such as image quality settings, sound quality settings, and operation settings for each device can be read and applied. As a result, the person who operates the video display device 100 or the person who operates the terminal device used for operating the video display device 100 is not affected by the setting change made by another person, and according to his / her preference. It is possible to apply and use the settings such as image quality and sound quality set in the above to the video display device 100.

However, it is not always necessary to store all the setting items that can be set according to the instruction of the operator of the video display device 100 in the individual information storage area 131 as individual settings for each operator. For example, when the setting menu configuration of the video display device 100 of this embodiment is as shown in FIG. 15, each item of "video setting", each item of "audio setting", and the like are set to the preference of each operator. It is desirable to store the setting contents set accordingly in the individual information storage area 131 as individual settings. On the other hand, the "reception setting" item, the "communication setting" item, etc., which are subordinate to the "initial setting", are not stored in the individual information storage area 131 as individual settings for each operator, but as common settings of the video display device 100. , Only one setting content may be stored in the other information storage area 133 or the like.

That is, in this embodiment, the settings in the "reception setting" item are settings related to an area where the video display device 100 is used, settings related to a broadcasting station that can be received in the area, and the like, and are usually set by each operator. It is not an item that changes the setting according to your preference. In addition, the settings in the "communication setting" item include settings related to the IP (Internet Protocol) address, subnet mask, default gateway, and DNS (Domain Name System) server of the LAN interface 151 of the video display device 100. Therefore, once the setting is made immediately after the introduction of the video display device, it is not necessary to change the setting frequently thereafter.

Therefore, the individual information storage area 131 is required by preventing the individual information storage area 131 from storing the setting contents related to the "reception setting" item and the "communication setting" item as individual settings for each operator. It is possible to reduce the capacity.

Further, when the video display device 100 is a television device having a built-in recording / playback function of a digital broadcast program, it generally has a function of displaying a list of recorded digital broadcast programs. Therefore, even in the video display device 100 of this embodiment, the setting of the initial display position when displaying the list of recorded programs, etc. should be stored in the individual information storage area 131 as individual settings for each operator. Just do it.

For example, the folder structure in the list display of the recorded programs of the video display device 100 of this embodiment is the configuration shown in FIG. 16, and the video display device 100 of this embodiment is further represented by three persons A, B, and C. Will be shared by the above three persons, and each of the three persons will record a digital broadcast program. In this case, when the video display device 100 of the present embodiment identifies the person A as an operator by the operator identification process, the individual settings for the person A are read from the individual information storage area 131 and applied. Therefore, in the list display of recorded programs, the setting is changed so that the "recorded program of person A" folder in the lower layer of the "user" folder is set to the initial display position. Similarly, when the person B is identified as an operator by the operator identification process, the "recorded program of person B" folder in the lower layer of the "user" folder is set as the initial display position. Further, when the operator information of the operator identified by the operator identification process is not stored in the individual information storage area 131, the standard setting is read from the ROM 103 and applied to list the recorded programs. In the display, you can change the setting so that the "All" folder is the initial display position. Alternatively, the list display may not be permitted.

By doing so, a person who operates the video display device 100 of this embodiment or a person who operates the terminal device used for operating the video display device 100 lists the programs recorded on the video display device 100. When a display is requested, the folder in which the program recorded by the user is stored can be displayed quickly, and the contents can be easily confirmed.

Further, when the image display device 100 is a television device having a function of connecting to a network such as the Internet and a function of network search and other application execution, as shown in FIG. 17, the display unit 121 displays a digital broadcast program image. It is possible to simultaneously display the window 121-3, the Internet access URL (Uniform Resource Locator) list window 121-4, the application icon list window 121-5 that can be executed by the video display device 100, and the like. In the video display device 100 of the present embodiment, the display positions of the digital broadcast program video window 121-3, the Internet access URL list window 121-4, and the application icon list window 121-5 are further displayed. Can be freely arranged, and the layout such as the display position of each window may be stored in the individual information storage area 131 as individual settings for each operator.

In addition, the initial display channel in the program video window 121-3 of the digital broadcast, the favorite URL in the URL list window 121-4 for Internet access, the icon of the frequently used application in the icon list window 121-5 of the application, and the icon of the frequently used application. Etc. may be set by each operator according to his / her preference and stored in the individual information storage area 131 as individual settings for each operator.

In this way, the video display device 100 of the present embodiment identifies the operator by the operator identification process, and the operation is stored in the individual information storage area 131 in advance according to the identified operator. Individual settings such as the display position of the window for the user, the initial display channel, the favorite URL, the icon of the frequently used application, and the like can be read and applied. As a result, the person who operates the image display device 100 or the person who operates the terminal device used for operating the image display device 100 is not affected by the setting change made by another person, and according to his / her preference. The image display device 100 can be used with the window layout set in the above.

Further, when the video display device 100 is a television device capable of displaying video content stored in a content server connected to a network such as the Internet, the video content can be downloaded from the content server and stored, or the content can be stored. It is possible to purchase paid video content on the server and watch it streaming. Further, the video display device 100 not only can display a large number of video contents on the content server in a list, but also has a function of displaying only the downloaded video contents in a list and a function of displaying only the purchased video contents in a list. Is desirable. In this case, the video display device 100 of this embodiment stores a list of video contents downloaded by each operator, a list of purchased video contents, etc. in the individual information storage area 131 as individual settings for each operator. You should keep it.

In this way, the video display device 100 of the present embodiment identifies the operator by the operator identification process, so that the list of video contents downloaded or purchased by the identified operator can be displayed. It can be read from the individual information storage area 131. As a result, the person who operates the video display device 100 or the person who operates the terminal device used for operating the video display device 100 displays a list of downloaded video contents and a list of purchased video contents on the video display device. When requested for 100, it is possible to extract and display only the video content downloaded by the person himself or the video content purchased by the person himself / herself from many video contents.
