Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a recording / reproducing method and a recording / reproducing apparatus. For details, if the target to be recorded is recorded with identification information attached, the target can be played back only when it matches the identification information entered during playback, and In this case, a personal recording library can be constructed, and a recording object which is considered undesirable in some cases can be regulated.

[0002]

2. Description of the Related Art The recent information flood has provided an environment in which a large amount of information can be obtained without discrimination for all persons.
However, since videos and movies dealing with violence scenes may adversely affect the healthy mental development of adolescents, current television broadcasts require that V When a discrimination signal called a chip is inserted and this discrimination signal is detected,
A device has been devised so that limited scenes such as the broadcast itself or violence scenes cannot be viewed.

[0003]

However, since the discrimination signal such as the V chip is inserted in a specific program of the television broadcast signal in advance, the television broadcast receiving such a discrimination signal is used. It is impossible to personally add to the signal arbitrarily.

[0004] Further, even if the person who records the television program wants to enjoy it personally, there are some recording objects that he does not want to show to others, especially children. on the other hand,
Especially when a recording device is shared and used at home, recording provided in the recording device such as a hard disk, unless a recording medium such as a videotape can be owned by a person. When it is a medium,
It is difficult to personally manage the recording medium itself.

[0005] For this reason, especially when a recording apparatus having a built-in recording medium is used in common, there are more opportunities for others to reproduce even a recording target that the user wants to enjoy only personally. As described above, even if the recording medium is a built-in recording medium, if the recorded object can be managed personally, a recording library for individuals can be constructed without depending on the V chip, and not only the object considered to be harmful, Information you want to enjoy personally,
The individual can be managed.

Accordingly, the present invention has been made to solve such a conventional problem. In particular, the present invention enables recording of identification information at the time of recording, and at the time of reproduction, only when the identification information matches. The recording target can be reproduced. As a result, even when a recording medium is commonly used, flooding of harmful information and the like can be suppressed, and a personal recording library can be constructed.

[0007]

According to a first aspect of the present invention, there is provided a recording / reproducing method according to the first aspect of the present invention, wherein when an object to be recorded is recorded with identification information attached thereto, At the time of reproduction, the recorded object can be reproduced only when the identification information matches.

According to a third aspect of the present invention, there is provided a recording / reproducing apparatus, comprising: a recording / reproducing unit; a recording unit; a control unit for controlling operation states of the recording / reproducing unit and the recording unit;

According to the present invention, for example, before recording, if the object to be recorded is one that the user wants to enjoy personally, identification information of the individual is input. When the recording medium is a recording medium such as a hard disk, which can easily manage files, this identification information is recorded in a file to be recorded. At the same time, when the input identification information is the first time, it is registered in the memory means.

[0010] When reproducing the recording object, identification information is input. Then, the input identification information is collated with the already registered identification information. When the collation results in a match, the mode shifts to the reproduction mode, and the recording target is reproduced.

However, when the identification information does not match,
At least the recording target cannot be played. As a result, even when the recording medium is commonly used, a personal recording library can be constructed, and as a result, children and the like cannot view the recording target with identification information without permission. It will also contribute to the healthy development of young people.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a recording / reproducing method and a recording / reproducing apparatus according to the present invention will be described in detail with reference to the drawings. In the embodiment, this recording / reproducing device is
A hard disk drive HDD is used as a recording medium,
This is a case where the present invention is applied to a video recorder having a built-in HDD.

FIG. 1 is a system diagram of a main part showing an embodiment of a recording / reproducing apparatus 10 according to the present invention, which comprises a recording / reproducing section 12 and an HDD 18 as recording / reproducing means. The recording / reproducing unit 12 performs a series of signal recording processes of converting the input video signal supplied to the terminal 14 into a digital signal, performing signal processing for compressing data by, for example, MPEG2, and then recording and recording the file in the HDD 18. Terminal 1
When the input signal of No. 4 is a digital signal, it is subjected to compression processing as it is and recorded.

A series of signal reproduction processing is performed in which the recording target reproduced from the HDD 18 is expanded and the original analog signal is returned to the terminal 16 as a reproduction signal. The reproduced signal is further supplied to the monitor 20, and the reproduced image is reproduced.

In this example, a magnetic disk having a storage capacity of about 100 to 500 gigabytes (GB) can be used as the HDD 18. HDD with such storage capacity
When using 18, maximum 300 hours, maximum 100
Recording of 0 titles is possible. In this case, the recording mode is a long-time (LP) mode of about 200 hours, and about 1 hour.
Three recording modes, a standard (SP) mode of 00 hours and a high quality (HQ) mode of about 50 hours, can be adopted.

The operation mode (recording / reproduction mode, identification information identification processing mode described later, etc.) of the recording / reproduction device 10 is controlled by a control unit 22 using a CPU.
The control unit 22 includes the recording / reproducing unit 12 and the HDD 18
And other operating states. Therefore, the control unit 22
Has a memory means (ROM) 24 containing a control program for executing various operation modes, a working memory and a memory means (R) for storing identification information.
AM) 26 is provided.

According to the present invention, the OSD (On Screen De
(mand) means 28 is provided so that a menu screen for registering identification information or the like or collating identification information can be displayed on the monitor 20 under the control of the control unit 22. Information such as identification information is input from the input unit 30. The input unit 30 can use a keyboard, a remote controller, an operation panel provided on the apparatus main body, and the like.

Further, in the recording / reproducing apparatus 10 according to the present invention, an interface section 32 capable of communicating with the outside is provided, and a communication cable (for example, IEEE) is connected to the external connection terminal 34.
E1394 communication cable)
Information from the outside can be taken into the control unit 22 and can be recorded on the HDD 18 in some cases. Therefore, the reverse process is also possible, and the recording target reproduced from the HDD 18 can be transmitted to an external device (recording / reproducing device, large-capacity mobile device, etc.) via the IEEE1394 communication interface unit 32.

According to the present invention, the recording / reproducing apparatus 10 can be configured to process basic operation modes (recording / reproducing, etc.). At this time, the recording target can be regulated by collating the identification information.

As a basic operation for this, first, registration processing of personal identification information (ID) at the time of recording is performed prior to the recording mode. Whether or not personal identification information is added to the recording target is optional. FIG. 2 shows an example of a menu screen used at that time.

FIG. 2 is an example of a recording selection menu screen SR particularly for identification information (ID). When it is desired to add identification information to a recording object at that time, registration processing of the identification information is performed. When the confirmation column 40 is clicked while the identification information has already been registered, the already registered information is displayed in the ID display column and, in this example, the name column.

On the other hand, when newly registering identification information, the confirmation column 41 is clicked. By this click, a mode for inputting identification information and a name is entered. For example, a four-digit number is input into a corresponding field to be identification information, and a name is input by katakana or hiragana.

When the confirmation column 42 is clicked after the input is completed, the input identification information and name are stored in the memory means 2.
6 and a transition to a recording menu screen is made. Since the recording menu is already known, its description is omitted, but at the same time as recording the recording target in the HDD 18, the identification information and name registered in relation to this recording target are recorded in the corresponding file.

When it is not necessary to add identification information to a recording target, the user can click on a column 43 in the same recording selection menu screen SR that does not require identification information.
As in the conventional case, only the recording target is recorded on the HDD 18. Therefore, in that case, anyone can freely play and enjoy the recording target.

Therefore, when the file recorded on the HDD 18 is viewed according to the contents of the recording selection at the time of recording, the recording state is as shown in FIG. In FIG. 3, when recording is performed without inputting identification information, that is, when recording is performed without an ID, anyone can play back the image. Only the person who matches the result of the comparison with the information can reproduce the recording target.

Next, when reproducing a recording target, a screen display as shown in FIG. 4 can be considered as the initial menu screen SP. In this screen display, a person who intends to reproduce first inputs identification information and a name.

When identification information or the like is input, collation processing with identification information or the like registered in advance is performed, and when the collation matches, for example, "all recorded programs can be reproduced." The message 45 is flashed, and by clicking the confirmation column 46 in that state, the mode is shifted to the normal reproduction mode. Therefore, the file specified in the reproduction file menu can be reproduced.

On the other hand, as a result of the collation, when the input identification information is different from the registered information or is not input at all, for example, “Some of the recorded programs are different because the identification information and name are different. Cannot be played back. " As a result, the user recognizes the existence of the special recording target, and if OK, clicks the confirmation column 46. As a result, the recording target without the identification information can be reproduced as usual.

Therefore, in addition to the program for realizing the basic operation mode for performing the recording / reproducing processing, identification information is added to the specific recording target as described above, and this identification information is collated at the time of reproduction. A management program for controlling the recording target is stored in the memory means 24 described above.

Next, the processing will be described with reference to FIGS. FIG. 5 shows a process for recording. When a recording mode is selected (step 51), a recording selection menu screen based on identification information is displayed (step 5).
2). An example of the recording selection menu is as shown in FIG.

When the user determines that the information is a recording object requiring identification information or the like (step 53), it is determined whether the registration is new registration of identification information or the like. Is executed (steps 54 and 55). Thereafter, by clicking the confirmation column (step 56), a new registration process is performed, and a transition is made to a normal recording mode (step 60).

On the other hand, if it is not a new registration but has already been registered in step 54, it is determined whether or not to use the registered information (step 57). Is clicked in the confirmation field,
The mode shifts to the normal recording mode, and the recording selection process based on the identification information ends (steps 56 and 60).

Next, the reproduction process will be described with reference to FIG. When the reproduction mode is selected, a reproduction menu screen as shown in FIG. 4 is displayed (step 62), and it is confirmed whether or not identification information has been input (step 63). When the identification information is input and the input identification information matches the registered identification information (step 64), playback is performed for the recording target having the same identification information and the recording target having no identification information. Is permitted (step 65).

When a recorded object using another identification information exists in the recorded file, the recorded object cannot be reproduced. Therefore, it is possible to select a recording target with the matching identification information and a recording target without the identification information as reproduction targets.

At step 64, if there is no matching recording target even if the inputted identification information refers to the registered identification information, the identification information is added including the identification information input error. Only unrecorded recording objects can be reproduced (step 66). Similarly, when the input of the identification information is not confirmed even after the lapse of a predetermined time in step 63, the same processing is performed, and only the file without the identification information is to be recorded (steps 67 and 66). By recording the identification information in the recording file in this manner, it is possible to limit the objects that can be reproduced.

In the above-described embodiment, the name is inputted in addition to the identification information. However, the name may be constituted only by the identification information such as numerals. Further, for example, identification information common to a family can be set as the identification information.

Further, in the above-described embodiment, an example has been described in which the identification information for the recording target is input or registered at the time of recording, but the identification information is registered at the end of the recording or the identification information is registered. If the recording target can be added, the identification information can be newly registered or added to the recording target when the recording target is reproduced. Conversely, erasure is possible.

Further, in the above-described embodiment, the recording / reproducing apparatus 10 having a built-in recording medium is exemplified. However, the present invention is also applicable to a case where a detachable recording medium such as a video tape is used. It can be easily understood that the recording / reproducing method and the recording / reproducing apparatus can be applied.

[0039]

As described above, in the recording / reproducing method and the recording / reproducing apparatus according to the present invention, when a recording object with identification information is reproduced, it can be reproduced only when the identification information matches. It is.

According to this, not all of the recorded contents recorded on the recording medium can be reproduced in common, but at least the recording target to which identification information is attached can be reproduced only when the identification information matches. By doing so, there is a benefit that a personal recording library can be constructed even if the recording medium is shared. As a result, there is a feature that a reproduction target can be restricted so that a video that the user wants to enjoy personally is not reproduced by a third party.

Therefore, the present invention is extremely suitable for application to a recording / reproducing apparatus having a built-in recording medium such as an HDD.
