Description

Be used to discern user's method

The present invention relates to a kind of be used for limited subscriber use the home video player for example VCR (video cassette recorder) or DVD (digital video disk) with the method for the video product avoiding the minor to watch forbidding, particularly a kind of by electronic recognition card (electronic identification card) rather than discern user's method by traditional password.

Describe traditional being used to below in conjunction with accompanying drawing and control the method that pupillary home video is play.With reference to Fig. 1, traditional home video playing device such as VCR or DVD comprise controller 12, keyboard 10, memory 16 and data reproduction unit 14.In conventional method, adult such as pupillary father and mother are by the particular password of keyboard 10 setting devices, and the minor uses the video product of forbidding with restriction.Such password is checked by controller 12, and is stored in the memory 16.

After password stores in the memory 16 during the displaying video product, controller 12 is according to the predetermined restriction to the particular video frequency product, or, show the message that a request user enters password on the display screen (not shown) according to having no truck with, limit the pre-provisioning request that the minor uses video product.Thus, when the user entered password, controller 12 was relatively entered password and is stored in password in the memory 16, only carries out replay operations when two passwords are consistent, otherwise the cancellation replay operations.

Except top method, can adopt more traditional method, wherein video play device is provided with special physical locks device, and device only could be operated when this physical locks is opened by user's physics key thus.

Under the situation of simple challenge, the fail safe of this traditional method is vulnerable, and its shortcoming is, as user when for example adult or pupillary father and mother forget password, this device can not use, and when the solution of password offers the user, the validity of the safety function of this device will reduce.Another shortcoming is the problem of losing the such physics key of the possibility of such physics key and safekeeping, and this is causing fault sometimes.

Therefore, the purpose of this invention is to provide a kind of video product that limited subscriber such as minor can only watch permission, a kind of method that can eliminate the aforementioned scarce limit of prior art of being used for.

Another object of the present invention provides a kind of method of coming restricting unauthorized use video product or video play device by accurate identification user.

According to the present invention, provide the electric or electronic installation of a kind of identification so that only allow authorized user to its method of operating, wherein discern the user by the personal information of detection record on the user's electronic identification card.The electronic recognition card comprises built-in chip, the personal information that is recorded with record.

Describe the present invention in detail only as the preferred embodiment of example, wherein below in conjunction with accompanying drawing:

Fig. 1 is the calcspar that prior art is used to control the conventional apparatus that pupillary home video plays;

Fig. 2 is used to explain that the restriction minor who adopts the inventive method can only watch the calcspar of equipment of the video product of permission;

Fig. 3 is a control flow chart of according to one preferred embodiment of the present invention minor being watched the controller that restriction is set; With

Fig. 4 is a control flow chart of controlling the controller of above-mentioned restriction operation according to one embodiment of the invention.

Referring to Fig. 2, the restriction minor of the preferred embodiment of the present invention can only watch the inventive method of the video product of permission to illustrate below at the VCR or the DVD that comprise controller 12, keyboard 10, memory 16 and data reproduction unit 14.

Be the identification user, the present invention adopts the electronic recognition card, and this electronic recognition card comprises various personal information, is recorded in the built-in chip, is read by specific card reader.

This device is provided with card reader 18, is used for reading relevant information from electronic recognition card 19.Controller 12 is provided with and utilizes the personal information that is recorded in the above-mentioned card to discern user's program, so that limit the operation that pupillary unauthorized is watched.

Attempt to limit user such as adult and the pupillary father and mother that minor's unauthorized is watched video product, by the keyboard 10 of said apparatus of structure according to a preferred embodiment of the invention, the information of the relevant restriction of input is to controller 12.In addition, details about this user and his or her mandate are read from electronic recognition card 19 by card reader 18, controller 12 is relatively by electronic recognition card 19 information of reading and the information that is stored in the memory 16 thus, if and can accept, new state of a control is set, and in memory 16, stores necessary information.After this, controller 12 is exported various control signals and is given data reproduction unit 14, thereby control suitably operating data regeneration unit 14 based on newly-installed state of a control.

Referring to Fig. 3, controller 12 checks in step 20 whether current state is reset mode.Reset mode can be keyed in a particular key by user's (being called " authorized user " later on) that restriction is set such as adult and such the attempting of pupillary father and mother and carry out on keyboard 10.If current state is a reset mode, controller 12 proceeds to step 22, whether carries out initial setting to check.Initial setting can carry out during the initial start of the device that is used to be provided with the restriction that unauthorized plays, thereby authorized user is by manufacturer or supplier's registration.

If also do not carry out initial setting, controller 12 proceeds to step 34, to read personally identifiable information's (being called " ID " later on) of user from electronic recognition card 19 (hereinafter referred to as " card ") by card reader 18.Then in step 36, controller 12 is relatively from blocking 19 ID that read and the default value that is stored in the memory 16, and check in step 38 whether ID can accept, if ID is unacceptable, controller 12 proceeds to step 32 stopping/finishing setting operation, and if ID is acceptable, then proceed to step 40, so that in memory 16, store ID, and further proceed to step 42.

In addition, if initial setting carries out, controller 12 proceeds to step 24 by step 22, reading ID by card reader 18 from blocking 19, and further proceeds to step 26, is stored in ID in the memory 16 with retrieval, proceeds to step 28 then, with mutual relatively ID.In step 30, controller 12 checks whether can accept from blocking 19 user ID of reading, if unacceptable, proceed to step 32 after this, stopping/finishing setting operation, and if can accept, then proceed to step 42.

In step 42, controller 12 beginning setting operations show setup menu simultaneously on the display window (not shown).Then, in step 44, controller 12 responses are carried out setting operation or are changed various control datas by handling the key data that keyboard 10 produces.Control data comprises the various restricting datas (for example age limit) of control minor video-see or watches irrelevant control data with limiting minor's video frequency program that the latter is used to set a forced process, checks ID when the displaying video product.

Referring to Fig. 4, the control procedure of restriction operation is described in detail as follows.In step 50, controller 12 checks whether current state is beholder's unrestricted model of setting shown in Figure 3 during setting up procedure.If current state is not beholder's definition mode, controller 12 proceeds to step 52, so that in statu quo program for playback is a video product; And if current state is beholder's unrestricted model, handle proceeding to step 54, whether be in unidentified state to check card 19.Above-mentioned steps also can be carried out during setting up procedure as shown in Figure 3.

If blocking 19 is to be in not identify other state, controller 12 proceeds to step 56, so that for the program that will be played, analyzes and watches the information of restriction about the minor, thereby check whether this program is set at the state that the minor watches restriction.As a result of, if program is not set to the minor and watches restriction state, controller 12 proceeds to step 52 to play this program, if and program is set to the minor and watches restriction state, then controller 12 proceeds to step 58, whether begin to check the ID of card 19, be authorized user to judge the user.

In addition, be in status recognition if block 19 in step 54, controller 12 proceeds to step 58 similarly, and the ID of beginning test card 19 reads ID by card reader 18 from blocking 19.In step 60, controller 12 retrievals are stored in the ID reference data in the memory 16, to discern the user in step 62 then.

Then, in step 64, controller 12 checks whether the user is a unauthorized user, if and user ID is acceptable, controller 12 proceeds to step 52 to play corresponding video frequency program, if and user ID is unacceptable, controller 12 proceeds to step 66 stopping current operation, and presses pre-determined number and repeat ID and check, and further proceed to step 68, if it is acceptable that user ID is proved to be, controller 12 proceeds to step 52, to play the associated video program, if it is and unacceptable, then proceed to step 70, to store top unacceptable ID in memory 16, so that can check the tabulation of unauthorized user ID after the authorized user.Controller 12 proceeds to step 72 then, with the power supply of shutoff device, and finishes current operation.As mentioned above, finish the restriction minor and use the process of forbidding video product.

Except the top example of restriction minor unauthorized video playback, above the inventive method can discern the user by checking such as complete personal information such as user name, age, sex and residences number, and correspondingly authorized user can be restricted to minority adult such as pupillary father and mother, and be registered in the memory 16, use this device to avoid minor and other human factor error.
