The main video information and subtitle information are the same as the sub video information. However, subtitle information includes data such as text and images displayed in subtitles instead of AV (Audio Visual) data.

  FIG. 4 is a diagram illustrating an example of a file system of the optical disc 13. The file system shown in FIG. 3 has a directory structure.

  First, as shown in FIG. 4A, in this file system, a main directory is prepared under root, and an index file, a navigation object file, a playlist file, and the like are stored in the directory.

  The index file includes information related to a menu for reproducing a data file that can be reproduced by the optical disc reproducing apparatus 1. For example, the optical disc playback apparatus 1 indexes a playback menu screen including items such as playback of all contents included in a playable data file, playback of only a specific chapter, repeated playback, and display of an initial menu. Based on the file, it is displayed on the display device 11.

  The navigation object file includes a navigation object including a command for controlling playback of a playlist included in a data file that can be played back by the optical disc playback apparatus 1. For example, the optical disc playback apparatus 1 is included in this file system. The content can be reproduced by selecting and executing one of the existing navigation objects.

  As shown in FIG. 4B, the playlist file includes at least a playlist and playlist extension information. A playlist is a collection of playback sections of AV data. That is, at least one pair of the start point (start address) and end point (end address) of the playback section is included.

  The playlist extension information includes at least the start address of the data block and the data block.

  The data block includes at least PiP metadata. The PiP metadata includes at least information indicating the horizontal and vertical coordinates and scale of PiP display as position information for display on the display means.

  The horizontal and vertical coordinates of the PiP display indicate the horizontal and vertical coordinates of the starting point of the position where the information is displayed. That is, it corresponds to the coordinate information of the claims. The scale indicates the size of the display area.

  In the present embodiment, the microcomputer 10 acquires the horizontal coordinates, vertical coordinates, and scale of the PiP display included in the above-described PiP metadata, and information on the input position touched on the touch panel 11a of the display device 11, It is determined which information of the main video information, sub-video information, and subtitle information is displayed as input position information, and an OSD of an operation related to the region is generated, and the upper left ( The generated OSD is displayed at a position whose origin is the PiP display horizontal coordinate and vertical coordinate). FIG. 5 shows a flowchart illustrating the above operation in detail.

  First, in step S1, it is determined whether or not a command to display sub-video information has been issued. If a command to display sub-image information has been issued (in the case of YES), a flag indicating that a sub-video is being displayed is stored in the memory 8. And proceed to step S2. The command for displaying the sub-picture information includes, for example, an operation for displaying the sub-picture information using the touch panel 11a, a sub-picture information display instruction based on the data read from the optical disc 13, and the like. If there is no instruction to display (in the case of NO), the process waits in this step.

  Next, in step S2, metadata (horizontal coordinates, vertical coordinates, scale) of sub-picture information is acquired from the optical disc 13, and the process proceeds to step S3.

  Next, in step S3, the position (horizontal coordinate, vertical coordinate) touched on the touch panel 11a of the display device 11 is acquired from the display device 11, and the process proceeds to step S4.

  Next, in step S4, it is determined whether or not the position touched on the touch panel 11a of the display device 11 acquired in step S3 is within the sub-video display area indicated by the metadata acquired in step S2. If it is within the display area (in the case of YES), the process proceeds to step S5, and if it is not in the sub-picture display area (in the case of NO), the process ends. That is, it identifies which area is designated among the areas for each of the plurality of streams from the position indicated by the instruction means and the position information for displaying the stream included in the stream read by the reading means on the display means. .

  Next, in step S5, the OSD for operating the sub-picture information is drawn with the horizontal coordinate and the vertical coordinate of the metadata as the origin (displayed on the display device 11). For example, referring to FIG. 6, the main video information 20 is displayed on the entire screen of the display device 11 with the main video information 20, the sub-video information 21, and the horizontal and vertical coordinates of the sub-video information 21 (x, y). Then, when the sub-video information 21 is displayed on the main video information 20 in PiP, this (x, y) is drawn as the origin (upper left) of the OSD 22. In FIG. 5, the case of sub-picture information has been described, but the same applies to the case of subtitles. In other words, the OSD of the related function is displayed on the display means so that at least a part of the area is overlapped with the area specified by the instruction area specifying means. In addition, the position where the OSD is displayed is determined based on the coordinate information included in the position information.

  In the flowchart of FIG. 5, the OSD display position is displayed at the upper left of the display area where the sub-picture information and the like are displayed. However, if the OSD protrudes outside the display area of the display device 11, What is necessary is just to slide so that it may fit in an area | region. That is, the OSD may be slid so that it is displayed so as to at least partially overlap the area where the sub-picture information or the like is displayed.

  In this embodiment, when the main video information area is instructed (touched), the OSD may be displayed on the upper left of the screen, which is the origin of the main video information, but if it overlaps the display area of the sub-video information or subtitle information May be displayed by sliding horizontally, downward or diagonally to a position where they do not overlap.

  According to the present embodiment, the horizontal and vertical coordinates and scale of PiP display included in the metadata recorded on the optical disc 13 and the input position information touched on the touch panel 11a of the display device 11 are acquired, and the input position is acquired. It is determined which information of the main video information, sub-video information, and caption information is touched, and an OSD of an operation related to the region is generated, and the upper left of the region is set as the origin Since the generated OSD is displayed at the position, the OSD for the target function can be displayed immediately. For example, when an area where subtitles are displayed is designated, the OSD related to the subtitles can be reliably displayed in the vicinity of the area, so that it can be operated intuitively and the operability of the OSD can be improved. it can.

  Further, since the OSD is displayed at the position where the upper left of the area is the origin, the OSD display position can be determined using the metadata recorded on the optical disc 13, and the OSD display position determination process Can be simplified. Furthermore, as shown in FIG. 7, even if the area moves, it can be easily moved following. In the case of FIG. 7, even if the horizontal coordinate and the vertical coordinate of the sub-picture 21 are moved from (x, y) to (x ′, y ′), the OSD 22 uses (x ′, y ′) as the origin, so it is easy to follow. It is.

  Further, since the content is composed of main video information, sub-video information, and subtitle information, and the position information is recorded so that the sub-video information and the subtitle information are displayed over the main video information, the content of the display device 11 Information assisting main video information such as caption information can be displayed on the main video information displayed on the entire screen.

  Further, since the horizontal coordinate, the vertical coordinate, and the scale are recorded as metadata, it is easy to search for data.

  In addition, since the metadata includes information for setting whether to display information such as sub-picture information and subtitle information, it is set whether to display sub-picture information and subtitles on the screen in the initial state. can do.

  In addition, since the display device 11 includes a touch panel, it is possible to instruct a region to be operated by the OSD by directly touching the screen, so that the operation can be performed more intuitively.

  Instead of providing the display device with a touch panel, the microcomputer 10 causes the microcomputer 10 to display a pointer on the screen of the display device 11 and operate a cross key or direction key provided on a remote controller or an operation unit of the main body. An area for displaying the OSD may be designated by moving the pointer. That is, the display device 11 serves as a pointer display means, and the microcomputer 10 serves as a movement means. In this case, since the function of the audio / video signal processing unit 7 is also a computer program executed on the microcomputer 10, the present invention can be easily configured as an information reproduction program.

  In the embodiment described above, the sub-image information is displayed superimposed on the main image information. However, the screen may be divided into a main image area and a sub-image area. Of course, the same applies to caption information. Further, the sub-image information and the caption information may be displayed at the same time. In this case, the corresponding OSD can be displayed by referring to the flag that displays each information.

  In the above-described embodiments, the optical disk is used as the recording medium. However, the present invention can be applied to a recording medium such as a hard disk or a semiconductor memory as long as the data structure and file system described with reference to FIGS. can do.
