Further, the system controller 17 stores the sub-picture position data Dsub and the navigation pack NV_
The size of the operation button (ie, the operation button area) is analyzed based on the “button position” information obtained from the PCK, and the operation button and the OSD are further analyzed based on the analysis result.
It is determined whether or not the display pattern and the OSD display pattern are overlapped. If the display pattern is overlapped, the coordinates of the OSD display pattern are offset-adjusted in advance so that the operation button and the OSD display pattern do not overlap. The position is corrected so that it is displayed side by side.

Further, the position correction processing will be described in detail.
For example, as shown in FIG. 5A, the OSD image data Do
When it is determined that the occupied area of the OSD display pattern obtained from (n) and the coordinate data Dp (n) overlaps the operation button area, the OSD display pattern is indicated by the sub-picture position data Dsub before performing the OSD display. The position to be
By performing offset adjustment while adding or subtracting a fixed amount of offset to or from the coordinate data Dp (n), new coordinate data Dp (n) for displaying the OSD display pattern at an appropriate position close to the operation button area 'Is generated. Then, by performing the OSD display based on the new (corrected) coordinate data Dp (n) ′, the OSD display patterns are arranged close to the operation buttons as shown in FIG. 5B. Position correction as follows.

Further, the system controller 17 displays a plurality of operation buttons according to the operation item information,
When displaying a plurality of OSD display patterns in association with each operation button, it is determined whether or not an overlapping situation occurs between the plurality of OSD display patterns. Then, when an overlapping situation occurs, the coordinate data of the overlapping OSD display patterns are offset-adjusted, so that the overlapping of the OSD display patterns is prevented and displayed.

Further, as described above, when the user operates the operation unit 18 to give a desired instruction, the system controller 17 sends to the video processor 14 an instruction for generating image data Dvd in accordance with the instruction. Analysis of the video manager information VMGI, video title set information VTSI, program chain information PGCI, sub-picture pack SP_PKT, and data search information packet DSI_PKT output from the digital signal processing unit 8 or the stream separation unit 10. Thus, various controls necessary for the reproduction operation are performed on the stream separation unit 10.

Next, the operation of the information reproducing apparatus having the above configuration will be described with reference to the flowchart shown in FIG. The operation of the OSD display will be mainly described.

In FIG. 6, when the power is turned on, the operation starts, and it is determined whether or not the DVD disk is loaded at a so-called clamp position (step S100).

When it is determined that a DVD disk is loaded, in step S102, information in a predetermined area of the DVD disk is reproduced, and it is determined whether an automatic reproduction command has been obtained. In addition, it is determined whether or not a reproduction start command has been issued from the operation unit 18 by the user.

Here, when the automatic reproduction command is not obtained and there is no reproduction start command from the user (in the case of "NO"), the process stands by until the reproduction start command is issued from the user. If an automatic playback command has been obtained or a user's playback start command has been issued ("YES"), the process proceeds to step S104, where playback of data recorded in the DVD video zone is started. Then, control goes to a step S106.

In step S106, the stream separation unit 10 sends the navigation pack NV_P
When CK is separated and extracted, its navigation pack NV
Based on the information of _PCK, it is monitored whether or not data indicating the “button area” exists in the stream being reproduced. If there is no data indicating the "button area", the reproducing operation is continued as it is.

On the other hand, when it is confirmed that there is data indicating the "button area", the flow shifts to step S108. Then, when the user operates the operation unit 18, the OS
It is determined whether or not a request to display D has been made. If the request has not been made (in the case of “NO”), the process returns to step S104 to continue the reproduction operation, and if the request has been made (in the case of “YES”), the process proceeds to step S11.
Move to 0.

In step S110, the video processor 14 generates image data for displaying an operation button from the “button area”, the “button position”, the sub-picture position data Dsub and the sub-picture data Ds. Display the button on the monitor screen.

Next, in step S112, the "button number" for identifying the "button area" relating to the operation button displayed in step S110, and the OSD image data Do (n) corresponding to the "button command" And the coordinate data Dp (n) and the color data Dc (n) are stored in the OSD image memory 1.
9 and generates OSD display image data Dosd.

Next, in step S114, the data of the "button area" and "button position" and the OSD display image data Dosd are analyzed, and the above-described step S110 is performed.
When the OSD is displayed in correspondence with the operation button displayed in step 2, it is checked whether or not the operation button and the OSD display pattern overlap.

When the operation button and the OSD display pattern overlap, the position is corrected so that the drawing coordinates of the OSD display image data Dosd become an appropriate position that does not overlap the “button area”.

In this embodiment, by correcting the position so that the lower right corner of the OSD display pattern is located near the upper left corner of the “button area”, the OSD display pattern and the operation buttons are arranged so as not to overlap. It can be displayed.

Next, in step S116, the most recently generated OSD display image data Dosd is compared with the previously generated OSD display image data, and the latest OSD display pattern is changed to the previously displayed OSD display pattern. Check if there is any overlap.

That is, based on information of a plurality of “button areas” and “button numbers” recorded on the DVD disk 2, a plurality of operation buttons and a plurality of OS
When the D display pattern is displayed, it is determined whether or not overlapping occurs between OSD display patterns.

Here, if it is determined that the OSD display patterns overlap (in the case of “YES”), the flow shifts to step S 118, where the OSD display image data Dosd generated most recently.
In order to adjust the drawing coordinates, an offset is added to the coordinate data by a fixed amount along the X coordinate or the Y coordinate, and the processing of steps S116 and S118 is repeated until it is determined that the OSD display patterns do not overlap.

When the adjustment of the drawing coordinates of the OSD display image data Dosd is completed, the flow shifts to step S120.
By supplying the OSD display image data Dosd to the video processor 14, the OSD corresponding to the operation button is provided.
The D display pattern is displayed on the monitor screen.

Next, in step S122, it is determined whether all the operation buttons specified by the operation item information have been displayed, that is, whether there is other button information. If there is other button information ("YE
In the case of "S"), by repeating the processing from step S110, the display of all the operation buttons and the display of the OSD display pattern associated with the "button number" of each operation button are completed.

When all the operation buttons and the OSD display pattern are displayed in this manner, for example, as shown in FIG.
On the monitor screen, one or more operation buttons corresponding to the operation item information recorded on the DVD disk 2 and OSD display patterns corresponding to the respective operation buttons are displayed side by side.

FIG. 7 shows that “main part playback”,
This shows a case where operation item information for displaying four operation buttons of “advance bias”, “cast”, “subtitle switching”, and “next selection” has been recorded on the DVD disc 2. Also, a case is shown in which OSD display patterns “1” to “5” are displayed in association with “button numbers” for identifying respective operation buttons.

Next, in step S124, it is determined whether or not the display period of the operation button whose display has been started in step S110 is still within the "end time of the button valid period". ), It is checked whether or not any operation has been performed by the user in step S126. If no operation has been performed, the processing from step S124 is repeated. If the display period of the operation button has reached “the end time of the button valid period”, the process proceeds from step S124 to step S128, and after performing a predetermined button operation specified by the standard, The process moves to S130. Step S1
If the user performs any operation at 26,
Even if the “end time of the button valid period” has not been reached, the process forcibly shifts to step S130.

In step S130, the OSD display pattern is deleted from the monitor screen. That is, for example, FIG.
The display of the OSD display patterns of "1" to "5" shown in (1) is ended, and only the operation buttons are displayed.

Next, in step S132, the process shifts to a request operation for the user, and the process from step S104 is repeated.

Note that the flowchart of FIG.
The operation of a typical case in which the method of reproducing the content recorded on the D disk 2 is displayed as the first main menu is shown. However, the information reproducing apparatus 1 uses the “next selection” shown in FIG. When the operation button of the item "" is selected, a submenu or the like is displayed in accordance with the operation item information recorded on the DVD disc 2, and the "button number" or "button command" is also displayed in the submenu or the like. OSD display corresponding to the above is performed.

As described above, according to the present embodiment, the “button number” and the “button command” included in the operation item information
The OSD display is performed according to the information of the OSD. Therefore, even if, for example, the operation buttons are displayed small because the display area of the monitor is small, the OSD display pattern that is predetermined in an appropriate size can be displayed by the user. By looking at
Operation without trouble can be performed. Further, since the OSD display pattern corresponds to the "button command", the user can operate the OSD display pattern to obtain the same effect as operating the operation button.

Note that a voice recognition system may be added to the system controller 17 of the information reproducing apparatus 1 according to the present embodiment, and the user may select and instruct a desired operation by speaking according to the description of the OSD display pattern. .
According to such a configuration, the description (characters and the like) of the OSD display pattern is relatively simple, so that the utterance time is shortened, and therefore, the OSD display pattern is easily affected by the background noise and the like, so that the speech recognition is performed. It is possible to solve the problem that the rate is reduced and the problem that the operability is reduced.

Further, in the present information reproducing apparatus 1, as shown in FIG. 7, each OSD display pattern is displayed at the upper left corner of each operation button, but the present invention is not limited to this. is not. For example, as shown in FIG. 8, OSD display patterns whose sizes are known in advance may be arranged and displayed at fixed positions in the monitor display area in the order of “button numbers” of the operation buttons. Further, the arrangement method may be one horizontal line, one vertical line, or a matrix arrangement of a plurality of rows / a plurality of columns, and may be appropriately determined according to the design specifications of the information reproducing apparatus.

Also, the case where the OSD display according to the operation item information of the DVD disk conforming to the DVD-Video is performed has been described. However, the present invention relates to a DVD belonging to another DVD family.
It is also possible to perform an OSD display according to the operation item information of the D disk. Further, the present invention can be applied to a case of reproducing another type of information recording medium such as a CD (Compact Disc).

As described above, according to the information reproducing apparatus and the operation item display method of the present invention, image data of a display pattern created in advance is provided, and based on the image data corresponding to the item information, Since the display pattern is displayed in association with the display of the operation item, for example, even if the display area of the monitor that displays the operation item is not in a form that can provide good visibility, it is created in advance. By displaying the displayed display pattern in association with the operation item, the user can visually recognize the display pattern and perform a desired operation equivalent to operating the operation item. Therefore, even if the operation item is displayed with poor visibility and operability, the visibility and operability of the display pattern are secured, so that the visibility and operability are substantially improved. The effect that it can be obtained is obtained.

Further, since the display is performed while avoiding a state in which the operation item and the display pattern are overlapped or a plurality of display patterns are overlapped and displayed, the visibility and the operability can be improved. .
