Abstract

PURPOSE:To make it possible for a specific user to gain access only within a specific range. CONSTITUTION:A decision is made whether a start keyword has been registered upon insertion of an IC card 20 and an operation menu is displayed on a control panel 14 if the start keyword has been registered. Only a content of the operational menu allowable for each user is displayed on the control panel 14. When a switch for selecting thus displayed operational menu is turned ON, a predetermined function is set and stored in a RAM 12 and the IC card 20. Various operations are then executed according to a conventional processing program. Upon finish of the operation, the IC card 20 is drawn out and managed by individual user. According to the constitution, accessible user can be limited and accessible range can also be limited for each user.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus capable of limiting a range accessible by a user.

[0002]

2. Description of the Related Art Commercially available VTRs (video tape recorders) are becoming more sophisticated and smaller. As the number of functions increases, the number of switches for setting various functions increases, and it is necessary to increase the space for that purpose. However, since the operation panel is downsized along with the downsizing of the VTR main body, it is difficult to secure a space in the operation panel for mounting these mechanical switches. Therefore, these switch functions have come to be secured by a software menu (a group of logical switches realized by software).

FIG. 8 shows the structure of a conventional commercial VTR.
In the figure, a processing program for managing the operation of the VTR main body 1 is stored in the ROM 11, and data for processing and generated data are stored in the RAM 12 of the internal memory. The ROM 11 and the RAM 12 are attached to the CPU 13 and are built in the VTR main body 1.

The RAM 12 includes a control panel 14
Servo process block 1 for controlling system control information (various kinds of information set by the software menu) necessary for the CPU 13 for normally controlling the operation content input from the tape running system and the drum rotating system.
R for controlling information necessary for 5, recording signal and reproducing signal
The information required for the F process block 16, the information required for the LONGITUDINAL process block 17 for controlling the longitudinal audio signal, the control signal, the time code signal, and the like, and the information regarding the interface with the external control device 18, such as the editing device, are controlled. The external interface process block 19 holds necessary information and the like.

Soft menus for setting each function are sequentially displayed on the control panel 14, and the contents are stored in the RAM 12 when the operator selects the switch displayed for each menu. ing.

[0006]

By the way, with a switch using a soft menu, it is usual to set a plurality of screens that are sequentially displayed according to their respective functions. Unable to judge the setting status of the switch. Therefore, even if the function that has been set and saved is changed for some reason, it is possible to assume that the function is saved and reuse it as it is.

In this case, it is necessary to recognize that the VTR main body 1 is different from the intended function only after the VTR main body 1 operates halfway. Then it is troublesome to display the soft menu again and set the switch. In some cases, the information recorded on the magnetic tape may be erased. Therefore, the present invention solves the above-mentioned problems, and proposes a recording / reproducing apparatus capable of reliably storing the functions individually set by the user.

[0008]

In order to solve the above problems, according to the present invention, a storage means for storing a processing program and data for operating each function of the recording / reproducing apparatus main body and the recording / reproducing apparatus main body are activated. Start-up data to be read, a reading means for reading a memory card storing limited data for limiting the processing program and data, and a start-up to start the recording / reproducing apparatus main body based on the start-up data stored in the memory card Means and
Based on the limited data stored in the memory card,
Limiting means for limiting the use range of the processing program and data, setting means for setting the processing program or data limited by the limiting means, and writing means for writing the processing program or data set by the setting means into the memory card. It is characterized by having.

[0009]

In FIG. 1, when the IC card 20 is inserted into the IC card insertion slot 21 (FIG. 7), it is judged whether or not the VTR activation keyword (FIG. 2) is registered, and if it is registered, the operation menu is displayed. Control panel 14
Displayed in. However, in the operation menu, only the contents permitted for each user (FIGS. 4 and 5) are displayed. Then, a predetermined function is set by selecting the selection switch of the displayed operation menu.
It is stored in the C card 20.

Next, various operations are executed according to a normal processing program. When the use is finished, the IC card 20 is pulled out and managed by the user individually. This makes it possible to limit the accessible users and the accessible range of each user.

[0011]

EXAMPLE Next, the recording / reproducing apparatus according to the present invention was used for VT.
An embodiment applied to R will be described in detail with reference to the drawings. The same parts as those described above are designated by the same reference numerals, and detailed description thereof is omitted.

FIG. 1 shows the structure of a VTR to which the recording / reproducing apparatus according to the present invention is applied. In the figure, the CPU 13 of the VTR main body 1 is provided with an IC card 20 in addition to the ROM 11 and RA1M2. In this IC card 20,
As will be described later, a part of the system control information stored in the ROM 11, that is, VTR activation keyword information and VTR operation menu access information are transplanted.

FIG. 2 shows a ROM 11, a RAM 12 and an IC.
The contents stored in the card 20 are shown. As shown in the figure, the ROM 11 stores various processing programs such as an initial diagnosis program and an RF recording / reproduction processing program, and the RAM 12 stores various information such as common software menu identification information and system control information. .. The IC card 20 stores VTR activation keyword information, VTR operation information access right information, and personal VTR operation information.

FIG. 3 is a flowchart showing the procedure of the VTR activation keyword search process 30. As shown in the figure, when the power is first turned on (step 31), the CPU 1
3 is a specific address of the ROM 11; here, the address #KK
By accessing KK and entering the initial diagnosis processing program (step 32), hardware initial check, system block check, memory check, etc. are performed.

Next, it is judged whether or not the IC card 20 is inserted (step 33). If the IC card 20 is inserted, then it is judged whether or not the VTR activation keyword is registered in the IC card 20. (Step 3
4) If it is registered, then the personal VTR operation information stored in the IC card 20 is stored in the RAM 13 (step 35). This brings the VTR main unit 1 into an operable state, and then a normal VTR processing program is executed (step 36). As a result, the activation keyword search process 30 ends.

When it is determined in step 33 that the IC card 20 is not inserted, a sentence or the like instructing the insertion of the IC card 20 is displayed next (step 37), and then the IC card 20 is inserted in step 33. It is determined whether or not it has been inserted, and then the same processing as described above is performed. If it is determined in step 34 that the VTR activation keyword is not registered, it is displayed that there is no right to use the VTR main unit 1 (step 38), and then the IC card 20 is inserted in step 33. Whether or not it is determined is performed, and thereafter, the same processing as described above is performed.

By using the IC card 20 in this way, it becomes possible for the user to easily preset the VTR main body 1 to the initial state of the desired function. Also, IC
If the card 20 is owned only by a specific user, the VTR cannot be used by anyone other than this, so that the range of use can be limited.

Further, the users of the VTR can be classified into, for example, an administrator, a maintenance person, an operator, etc., and the usage ranges of these users can be divided as shown in FIG. In this example, the operator's use range is the operation menu information and the operation switch information, the maintenance person's use range is the operation switch information and the maintenance adjustment menu information, and the administrator can use the entire range. ..

In the case of an operator, for example, as described above, only the operation menu information and the operation switch information can be used. Therefore, as shown in FIG. 5, the address # BBB1 where the management information of the IC card 20 is stored and the test information are stored. Forbidden code FF for the address # BBB4
h is set. The information set with the prohibition code FFh is not disclosed to the user.

FIG. 6 is a flowchart showing the procedure of the VTR operation information access right limitation processing 40. First, the corresponding interrupt processing program is activated by an interruption caused by access to the management information menu, the operation menu, the operation switch, the maintenance adjustment menu, etc. (step 41). Next, the address #BB in the IC card 20
The VTR operation information access right information stored in the BB is referred to (step 42), and subsequently it is determined whether the prohibition code FFh is set (step 43).

If the prohibition code FFh is not set, for example, in the case of an operator, as shown in FIG. 5, PICTURE-MONITOR information (a menu for selecting a video signal to be sent from the MONITOR-OUTPUT terminal of the VTR main body 1). Is given the right to access, and therefore the prohibition code FFh is not set, in this case, various switches can be operated.

And this PICTURE-MONITO
Information selected by the R information, such as an input video signal, a demodulated signal, and a TBC signal, is stored in the RAM 12 and the IC card 20.
It is stored in the area of the personal VTR operation information (step 44). Next, processing corresponding to various interrupt processing programs as described in step 41 is performed (step 45), and this ends the access right limiting processing 40.

If it is determined in step 43 that the prohibition code FFh is set, for example, in the case of an operator, DROP-OUT-COMP as shown in FIG.
Since EN (choice of whether to correct dropout due to dropout) is not given the right to access,
Next, the message that you do not have access rights is displayed (step 46),
Subsequently, without performing any processing (step 47), the access right limitation processing 40 ends.

As described above, in this VTR, by using the IC card 20 holding the information to which the access is permitted, only the information necessary and sufficient for carrying out the task in charge of the user is referred to or changed. be able to.
Also, since other information can be masked, troubles due to negligence can be prevented.

The above-mentioned IC card 20 is inserted from the insertion port 21 of the VTR main body 1 as shown in FIG. 7, and reading and writing are performed. Then, various menus are displayed on the control panel 14. A cassette tape (not shown) is inserted from the cassette insertion port 22.

The IC card reading / writing device 23 and the personal computer 24, which are separate from the VTR main body 1, can read / write the IC card 20. In this way, it becomes possible to mechanize the contents confirmation, change, and update of the IC card 20 independently of the VTR main body 1. As a result, the information set individually by each user can be managed by the individual user, so that the information can be managed safely and surely.

[0027]

As described above, the present invention is a VTR.
The setting switch information of each function in the recording / reproducing apparatus is stored in a storage means different from the recording / reproducing apparatus main body such as an IC card.

Therefore, according to the present invention, it is possible to limit the users of the recording / reproducing apparatus, and it is possible for each user to manage the information in which the function required for each user is set. Therefore, it becomes possible to store the information safely and surely. Further, it is possible to confirm or update the function set in the storage means by a device different from the recording / reproducing apparatus main body.
