Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information reproduction operation propriety display device and an information reproduction operation propriety display method.
[0002]
[Prior art]
Generally, an information recording medium in which reproduction information including a video signal and an audio signal is recorded and a plurality of types of reproduction processing information added corresponding to the reproduction information are recorded is widely used as a video CD, a DVD, and the like. are doing.
[0003]
The reproduction processing information on the information recording medium includes, for example, multi-angle reproduction processing, subtitle reproduction processing, dubbing audio selection processing, main / sub audio selection processing, stereo audio selection processing, and the like. A desired reproduction process is selected by operating an operation command key provided, an operation command key provided on a remote controller, and an operation command key connected to a personal computer, and reproduction information is obtained by an image monitor and an audio monitor.
[0004]
The multi-angle reproduction processing, which is one type of such reproduction processing information, can arbitrarily select and reproduce a plurality of simultaneously proceeding videos. The subtitle reproduction processing includes a plurality of types of video corresponding to each of the multilingual languages. The subtitles can be arbitrarily selected and reproduced, and the dubbing sound selection processing can arbitrarily select and reproduce non-dubbed sounds in at least one country language and dubbed sounds in at least one country language. The main / sub sound selection processing can arbitrarily select and reproduce a main sound in at least one country's language and a sub sound in at least one country's language. A stereo sound formed by the main sound and the sub sound can be selected and reproduced.
[0005]
In this case, the information recording medium is rarely created so that all the selection processes can be performed, and only a few types of selection processes can be performed, and the types are unique to the information recording medium. In addition, there is almost no case where the same option is provided for all of the video programs in one information recording medium, and a scene where one reproduction process works effectively and a scene where it is invalid are mixed.
[0006]
For this reason, when selecting the reproduction process, the operation key for instructing the reproduction process to be performed on the information recording medium currently being reproduced is pressed by the user regardless of whether the operation command is permitted or not, and the operation command is issued. When the operation is permitted, the operation is executed, and when the operation command is not received, the user is notified that the operation is prohibited.
[0007]
For example, when a multi-angle portion in one video program is being played, operation keys for selecting a multi-angle are displayed in an OSD (on-screen display) state, and the multi-angle is displayed. When an unconfigured portion is being played, the operation keys for multi-angle selection are not displayed at all on the OSD screen, or the operation command keys for multi-angle selection are marked with prohibition marks on the OSD screen. Is displayed.
[0008]
Also, in the case of the dubbing sound selection processing, the main / sub sound selection processing, the stereo sound selection processing, and the like, when the corresponding reproduction processing exists, the operation command key for the selection is displayed, and the corresponding reproduction processing is performed. When there is no display, the display is not performed on the OSD screen.
[0009]
In some cases, operations such as skip-up during reproduction are prohibited on the DVD recording medium. In such a case, when the operation key for the skip-up instruction is pressed, the operation is not included in the DVD recording medium being reproduced. The playback processing information, for example, VOBU UOP CTL (video object unit user operation control information) is analyzed, and when the skip-up command is prohibited, the user is notified of the skip-up prohibition using the OSD screen. ing. Specifically, by displaying the prohibition mark 3 superimposed on the image displayed on the display screen 2 of the monitor device 1 shown in FIG. 4, the user is notified that the DVD recording medium is skip-up prohibited. ing.
[0010]
Then, when the recording medium is a DVD, the operation of the display control of whether or not the reproducing operation is possible in the conventional information reproducing apparatus is executed as shown in the flowchart of FIG.
[0011]
That is, as the DVD is started to be reproduced, the VOBU UOPCTL information is first read from the disk and stored in the work memory in step S9, and then the process proceeds to the next step S10, in which input of operation keys for commanding various reproduction operations is performed. It is determined whether or not the input has been performed. If there is no input (in the case of No), step S9 is executed again. If the input has been input (in the case of Yes), the process proceeds to the next step S11.
[0012]
Step S11 is to start analyzing the VOBU UOP CTL information and determine whether or not the operation key pressed in the next step S12 is prohibited from operating. ), The operation proceeds to step S13 to display an operation prohibition mark (see FIG. 4) by OSD display, and the series of operations ends.
[0013]
On the other hand, if the operation key pressed corresponds to the operable state in step S12 (No), the process proceeds to step S14, where the reproduction operation corresponding to the pressed operation key is executed, and the series of operations ends.
[0014]
[Problems to be solved by the invention]
The display control device of the reproduction operation permission / prohibition in the conventional information reproduction device determines what operation command key is valid for the video scene currently being reproduced when the operation command key is actually pressed. It is determined that the reproduction processing information is to be analyzed, and if the reproduction operation is possible, the reproduction processing is executed as it is. If the reproduction processing operation is prohibited, a prohibition mark is superimposed and displayed using an OSD screen or the like. Therefore, there are the following problems.
[0015]
The first problem is that since it is determined that the reproduction processing operation is prohibited after the operation command key is actually pressed, the usability is poor, that is, it is not known beforehand whether the reproduction operation desired by the user is possible or not. It is not easy to use.
[0016]
The second problem is that a mode in which the user is informed that the reproduction processing operation is prohibited is superimposed on the original reproduction screen and a prohibition mark is attached thereto, and thus overlaps with the background image (the original reproduction screen). Therefore, it is not clearly displayed and the interpretation is very incomprehensible and inconvenient.
[0017]
Therefore, an object of the present invention is to know beforehand the validity / invalidity of an operation command key in many types of reproduction processing without actually pressing the corresponding operation key, and to further clarify whether the reproduction operation is valid or invalid. It is an object of the present invention to provide an information reproduction operation propriety display device and an information reproduction operation propriety display method, which greatly improve the usability.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, the present invention is applied to a case where the information recording medium on which the reproduction information and a plurality of types of reproduction operation information added corresponding to the reproduction information are DVDs is used. Is an example of an availability display device capable of displaying information along with the display of playback information and a method of displaying the availability of information playback operation.
[0029]
The monitor device 1 shown in FIG. 1 can reproduce a display based on a reproduction signal obtained by reproducing a DVD as a normal screen state (see FIG. 4), and displays an information reproduction operation enable / disable key. Is performed, the display screen is configured to have a display control unit that controls the normal screen to be changed so that the strip-shaped operation enable / disable key display 5 is selectively displayed above the normal screen.
[0030]
Then, the operation of the display control of the reproduction operation permission / prohibition in the information reproducing apparatus includes the first operation step of giving an instruction to display the information operation permission / prohibition and the instruction based on the first operation step. A second operation step of decoding reproduction operation information obtained by reproducing the information recording medium to obtain information on an enable / disable key of the information reproduction operation; and a possible / inhibited information obtained in the second operation step And a third operation step of performing display control so that key information display is performed together with the reproduction information. When the recording medium is a DVD, the operation is specifically performed as shown in the flowchart of FIG. You.
[0031]
That is, as the DVD is started to be reproduced, it is first determined in step S1 whether or not the operable display key has been turned on. If the operable display key has not been pressed (in the case of No), step S1 is executed again, and When the display key is pressed (in the case of Yes), the process proceeds to the next step S2 to execute the operation of changing the aspect ratio, and the reproduction screen displayed on the monitor device 1 in FIG. Is displayed as the vertical / horizontal magnification screen 4 with the vertical magnification reduced, and the black screen band is positioned above the vertical / horizontal magnification screen 4, and the process proceeds to step S3.
[0032]
In step S3, since it is conceivable that the vertical / horizontal magnification screen display executed in step S2 may become an unnatural state in which the picture is crushed up and down as a picture, a function of correcting the horizontal direction is shortened. Is performed by selectively turning on / off the switch.
[0033]
Then, it is determined in step S3 whether or not the above-described screen automatic adjustment function is on, and if it is on (in the case of Yes), the process proceeds to the next step S4, where an unnatural state of crushing up and down is obtained. After performing the correction for shortening the horizontal direction of the screen, the process proceeds to step S5. Also, when it is determined in step S3 that the automatic screen adjustment function is off (in the case of No), the above-described step is performed. Proceed to S5. The vertical / horizontal magnification screen 4 shown in FIG. 1 shows a state when the screen automatic adjustment function is turned off.
[0034]
Step S5 superimposes the operation enable / disable key display 5 on the black screen band located at the top of the vertical / horizontal magnification screen 4, and the operation enable / disable key display 5 includes a pause key 5a, a first skip key 5b to a The pause key 5a is a key for instructing the pause of the reproduction, and the first skip key 5b is a command for skipping to the beginning of the currently reproduced program video track. The second skip key 5c gives an instruction to skip to the next track of the currently playing program video track, and the third skip key 5d sends the currently playing program video at high speed in the reverse direction. The fourth skip key 5d is for giving an instruction to play back the program video being played back at high speed in the forward direction.
[0035]
As for each key (reference numerals 5a to 5e) in the operation enable / disable key display 5, the key display (icon display) corresponding to the operable state is displayed in a conspicuous color in the next steps S6 to S8, and the operation is prohibited. The displayed key is displayed in a gray-based color, and the distinction between operable / inhibited operation is clearly made.
[0036]
That is, step S6 is to analyze the VOBU UOP CTL information being reproduced by discriminating the operable / prohibited operation of each key of the operability key display 5 located at the top of the vertical / horizontal magnification screen 4. In step S7, it is determined whether or not there has been a change between the immediately preceding VOBU UOP CTL information and the current information. If it is determined that there has been no change (in the case of No), the process returns to step S1 at the beginning, and the subsequent steps are performed. It is re-executed, and if it is determined in step S7 that there is a change (in the case of Yes),
Proceeding to step S8, the key display corresponding to the operation (icon display) is changed to a conspicuous color, and the key display corresponding to the operation prohibition is changed to a gray-based color, and then returned to the initial step S1 to be changed. Subsequent steps are re-executed.
[0037]
The user operation prohibition information in the reproduction processing information obtained by setting the DVD in the DVD drive and reproducing the information is stored in the VOBU UOP CTL information area based on the disc standard, and the PGC UOP CTL information ( Since the information is stored in the area of (program unit / user operation control information), such user operation prohibition information can be used.
[0038]
According to the information reproduction operation propriety display device according to the embodiment of the present invention described above, the vertical / horizontal magnification screen 4 (see FIG. 1) obtained when the operation propriety of the operation key is displayed by OSD is displayed on the original reproduction screen. In contrast, only the vertical magnification is reduced while the horizontal magnification remains unchanged, but as shown in FIG. 3, a display area located below the operation enable / disable key display 5 has an aspect ratio smaller than the original reproduction screen. May be displayed as it is in a reduced state. In this case, since a black screen portion is generated in the right direction, the operation enable / disable key display 5 can be expanded and displayed at that portion.
[0039]
The operation permission / inhibition display key is configured by a dedicated key, but may be configured to be used also as an existing operation key, or a command by the operation permission / inhibition key may be executed by pressing and holding the existing operation key. The configuration may be such that a plurality of existing operation keys are simultaneously pressed.
[0040]
The display control is configured to change the aspect ratio of the screen corresponding to the reproduction information to display the information, and to display information of the enable / disable key in an empty display area formed by the display. Although the screen corresponding to the original playback information is displayed in a reduced size, the aspect ratio may be changed depending on whether the screen corresponding to the original playback information is a standard size, a high definition size, or a wide size. Of course, the change or the reduction ratio can be selectively performed.
[0041]
The information recording medium to which the present invention is applied has been described using a DVD as an example in which reproduction information and a plurality of types of reproduction operation information added corresponding to the reproduction information are recorded. As a matter of course, an MO, a CD, or the like may be used as long as a plurality of types of reproduction operation information added thereto are recorded.
[0042]
【The invention's effect】
As apparent from the above description, the information reproduction operation propriety display device and the information reproduction operation propriety display method according to the present invention do not determine that the reproduction processing operation is prohibited after the operation command key is actually pressed. Further, when a special operation permission / inhibition key is operated, whether or not the reproduction operation is possible is displayed in advance, so that the usability is remarkably improved.
[0043]
In addition, the mode for displaying to the user that the playback processing operation is prohibited is displayed in a display area different from the original playback screen, so that the operation enable / disable key is displayed, so that the display may overlap the background image (the original playback screen). There is no display, and the operation enable / disable key display is displayed in a state that is clear and easy to read, so that usability is remarkably improved.
[0044]
Therefore, according to the present invention, the validity / invalidity of the operation command key in many reproduction processing types can be known in advance without actually pressing the corresponding operation key, and it is also clear whether the reproduction operation is valid or invalid. Thus, it is possible to provide an information reproducing operation propriety display device and an information reproducing operation propriety displaying method which greatly improve the usability.
