 The present invention relates to a video display device, and more particularly, to an apparatus and method for controlling a video display device using an RFID tag that recognizes a user using an RFID tag and switches to a setting suitable for the user.

Recently, due to the proliferation and price reduction of hard disks, PVR (Personal Video Recorder) / PDR (Personal Digital Recorder) using hard disks are being sold in place of video records using analog tapes. In addition, due to the falling price of the broadcast viewing device and the diversification of the PVR / PDR function, a single PVR / PDR device provides a multi-user broadcasting environment.

Meanwhile, as part of providing a ubiquitous environment, RFID (Radio Frequency Identification) is emerging. RFID is a short-range wireless communication that stores unique information of objects / persons on a chip called a tag and attaches them to objects / persons to automatically recognize the surroundings of objects / people and process information in real time with existing information technology systems. Technology.

Until now, when a broadcasting viewing apparatus of one PVR / PDR provides a broadcasting environment of a multi-user, a method of setting the broadcasting viewing environment of a multi-user has been made manually.

If a user wants to switch to the viewing environment of another user while watching a broadcast using PVR / PDR or is using the PVR function, the user can directly exit from the current user environment with the wireless keyboard when a remote controller or wireless keyboard is provided. After it comes out, it passively switches to the new user's viewing experience.

Hereinafter, a viewing environment setting method of a video display device according to the prior art will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a control method of a video display device according to the related art first determines whether to switch to a specific user mode when a user inputs a power-on command (S11 to S12).

Subsequently, the determination result (S12), if the user wants to switch to a specific user mode to display a user change menu (S13).

Then, the specific user to be changed is selected and the user is switched to the specific user environment (S14 to S15).

Subsequently, when the user inputs a power off command, the process ends (S16).

As described above, when a user changes a setting to an environment suitable for him or her, the user is fixed to the environment unless another user appears and watches it again, unless it is manually changed again. For example, the rating restrictions may be released, or a part which a user does not want to disclose such as a favorite channel may be disclosed.

In addition, when the user requests the reservation, the user who applied for the alarm tries to change the alarm or channel even when he / she is absent. On the contrary, when the reservation is recorded, the current user can record while watching the program. It happens.

In addition, the user manually recognizes the user through a remote control, and there is an inconvenience in that the user needs to change to the default setting when viewing a plurality.

The present invention has been made to solve the above problems, and the object of the present invention is to enable the user to recognize the user using the RFID tag and automatically switch to a setting suitable for the user.

In addition, there is another purpose to allow a plurality of users to control the viewing environment for each user.

It is characterized by building.

Preferably, the detecting of the user identification information includes determining whether automatic recognition is activated when a power-on command is input, and reading the RFID tag and detecting user identification information according to the corresponding tag when the automatic recognition is activated. It is characterized by including the steps.

More preferably, the controlling of the viewing environment setting comprises: setting a viewing environment suitable for a plurality of users by identifying common conditions among viewing environments preset by a plurality of users when the plurality of users is a plurality; It is characterized by including the step of setting the viewing environment preset by the recognized user.

More preferably, the step of setting a viewing environment suitable for the plurality of users includes extracting a common preference channel of the plurality of users, and determining the viewing grade restriction among the plurality of users to apply the viewing grade restriction first. And the step of applying the reservation algorithm according to the presence or absence of a corresponding user when reservation viewing and recording are set.

More preferably, the step of applying the parental level restriction preferentially is a step of restricting the non-viewing priority when viewing with the non-viewing user.

More preferably, the applying of the reservation algorithm may include determining whether a specific individual has applied for the reservation viewing, and if the specific individual has applied, determining whether the specific person exists at the time of the reservation viewing; And automatically changing the channel after the notification message if the specific person exists, and displaying only the notification message if the specific person does not exist.

Hereinafter, an apparatus and method for controlling viewing environment of a video display device according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram illustrating an apparatus for controlling viewing environment of an image display device according to the present invention, and FIG. 3 is a flowchart illustrating a method for controlling viewing environment of an image display device according to the present invention.

As shown in FIG. 2, the apparatus for controlling viewing environment of an image display device according to the present invention recognizes an RFID provider 100 providing RFID for each user, the RFID tag for each user, and configures the environment for each user. A user recognition unit 200 which controls whether the plurality of users are recognized and controls the viewing environment for each user, and a received image may be displayed according to the viewing environment set by the user recognition unit 200. It is configured to include an image processing unit 300 for processing.

Here, the user recognition unit 200 is an RFID reader 201 for decoding user identification information from a signal transmitted from an RFID tag and outputting user identification information, and a key input unit for inputting user information, user setting conditions, and the like ( 202, a memory 204 for storing user information and user setting conditions input through the key input unit 202, and determining whether the user recognized by the RFID reader 201 is a pre-stored use. And a control unit 203 which controls to store the user information and the user setting condition inputted through the key input unit and matches the user information and the setting condition corresponding to the recognized user and outputs a corresponding control signal. .

Referring to the operation of the viewing environment control apparatus of the video display device configured as described above is as follows.

First, when a power-on command is input to the image display device, it is determined whether the RFID recognition unit 100 is activated to recognize the tag. If automatic activation is enabled, tag information is received from the RFID provider unit 100.

That is, the RFID reader 201 recognizes any one of the first to third tags 101 to 103 of the RFID provider 100, and the controller 203 recognizes the RFID reader 201. It is determined whether a user corresponding to the received tag information is previously stored in the storage unit 204.

If there is no user previously stored in the storage unit 204 as a result of the determination, a menu screen for inputting a user ID and a condition desired by the user is displayed, and the user refers to the corresponding key using the key input unit 202. After setting the condition, the condition is stored in the storage unit 204.

In addition, if the user corresponding to the recognized tag information is a user that is pre-stored in the storage unit 204, the image processing unit 300 so that the received image can be displayed in accordance with a preset viewing environment in the storage unit 204 Output the corresponding control signal.

Therefore, user recognition uses RFID tags of belongings possessed by a specific user, and if not a registered user, enters the user registration menu, and selects the viewing environment (signal channel, parental level, tag change password, Auto power on / off, reservation watching, reservation recording, etc.) can be set.

Therefore, once the user is registered, the RFID reader 201 periodically checks the presence or absence of the setting change, and if there is only one recognized user, viewing can be made in consideration of the viewing environment of the corresponding user. For example, when there are a plurality of users, a corresponding viewing environment is provided according to a pre-stored multi-user selection processing method when there are a plurality of users.

That is, in the case of the preference channel, the channel setting can be made by extracting the common preference channel, and in the case of the restriction of the viewing grade, the case where the user who cannot watch is viewed together is restricted first.

In addition, in the case of reservation viewing, automatic channel switching is controlled according to whether or not a user who has set up reservation viewing exists, and in the case of reservation recording, the recording start is informed according to whether or not there is a recording scheduler.

Referring to FIG. 3, the method for controlling the viewing environment of the image display device according to the present invention configured as described above is first determined whether the automatic recognition is activated when the user inputs a power-on command (S101 to S102).

Subsequently, the RFID tag is read when the automatic recognition is activated (S103).

In operation S104, it is determined whether the user corresponding to the read tag is a registered user.

As a result of the determination (S104), if the user is a registered user, it is determined whether there are a plurality of users (S105). In other words, it is determined whether there is a user other than the currently recognized user.

As a result of the determination (S105), if there are a plurality of users, the common preference channel change algorithm, the grade limit viewing change algorithm, the plurality of reserved viewing / recording algorithms, and the automatic on / off function algorithm are appropriately applied (S106 to S109).

On the other hand, if the determination result (S105), if there are not a plurality of users, the currently recognized user changes to the preset viewing environment mode (S111).

In addition, the determination result (S104), if the user corresponding to the read tag is not a registered user provides a basic viewing environment (S112).

If the determination result (S102), automatic recognition is not activated, switch to the common or previous user mode (S113).

Finally, when the user inputs the power off command, the process ends (S110).

As described above, the present invention can be broadly divided into three parts, and may include a user recognition method using RFID, a method of processing a selection function when a plurality of users exist, and a special function provided in the case of a single or personal image display device.

User identification is performed using RFID tags, registration is performed according to whether or not the user is a registered user. The same method applies.

In the case of reservation viewing, it is determined whether the user exists at the time when the reservation watching program is broadcasted, and if the user exists, the channel is automatically changed after the notification message.In the absence, only the message showing by whom reservation reservation is set is displayed. Channel switching is not performed. A separate algorithm is applied for reservation recording.

On the other hand, the auto power on / off function can also be usefully used, and if a specific registered user appears, and the auto on function is set, the user can be automatically turned on even when the user is off, and the auto off function can recognize an individual user. Make it available separately from the function. If no viewer is recognized for a certain time, it can be turned off automatically, which is useful for single or personal video display devices.

As described above, the apparatus and method for controlling the viewing environment of a video display device according to the present invention have the following effects.

First, even in the case of a plurality of users, there is no need to manually change the user environment provides more convenience to the user.

Second, even in the case of a plurality of users, the privacy of the individual can be more protected by appropriately setting the viewing environment according to user recognition.

Third, if the user does not exist at the time of the reservation request, the channel switching is not performed, thereby increasing the viewing satisfaction of the user.

Fourth, the automatic power on / off function may also be usefully applied to a single person or a personal video display device.
