For this reason, it is possible to view the booklet-type content with the same operation feeling as that of a DVD-video disc such as a general movie. That is, the spread page of the booklet-type content is displayed as a menu screen in a DVD-video disc such as a movie. If the user frequently uses such a DVD-video disc, how to operate the menu screen. You can understand at a glance. In addition, since the main video on a DVD-video disc such as a movie is an animation that turns a double-page spread, the booklet type is the same as the DVD-video disc such as a movie that selects the main video to be viewed from the menu screen. You can move the content browsing page to the next page or return to the previous page.

  On the creation side of booklet-type content, a page turning animation video is incorporated as a VOB file as a main video, a spread page image is incorporated as a VOB file, and a page turning that can be played on each spread page. Control information such as animation movie settings and the setting of the next spread page to be displayed upon completion of playback of the page-turning animation need only be incorporated as an IFO file. There is also an advantage that booklet content can be created very easily in the same manner as a DVD-video disc.

  DVD-video is a Kochi application format (standard) established by the DVD Forum for recording a plurality of video, audio, and subtitles on a DVD.

  The digital content realized by the present invention is a booklet-type content (digital book content), which not only allows each spread page to be browsed, but also creates a spread page as another spread page as a presentation effect at the time of browsing. When the page is switched, the page turning animation (turning moving image data) in which one side of the spread page that has been viewed so far is flipped is reproduced to make the content look better. The present invention uses a file structure conforming to a predetermined video content playback format such as a DVD-video format so that such a booklet type content can be easily played back and browsed on a general DVD playback device, and is efficient. Has been realized.

  That is, when it is created in accordance with a predetermined video content playback format such as a DVD-video format, a menu screen for accepting a playback operation of the main video can be displayed while displaying a menu video as a background. For this reason, in the present invention, each spread page of the booklet-type content is displayed as a menu video as a background of the menu screen. At the same time, this menu screen can accept a selection operation for selectively reproducing the main video like the so-called chapter list screen and title list screen. As a video, the page turning animation for turning the spread page displayed on this menu screen to the next spread page and the page turning animation for turning the spread page displayed on this menu screen to the previous spread page are assigned. .

  As a result, when an operation for selecting / reproducing the main image from the menu screen displaying the spread page image of the booklet-type content is performed, the page turning animation, which is the main image with the selected / reproduced operation, is reproduced and displayed. That is, the selection / playback operation of the main video is a page turning operation in the present invention. When the reproduction of the page turning animation, which is the main video image selected and reproduced, is finished, the screen returns to the menu screen displaying the spread page image again. However, the menu image on the menu screen that is displayed after the main video has finished playing is not the spread page image that was displayed on the previous menu screen, but another spread page that displays the previous spread page that was turned by the page turning operation. It becomes a page image. In this way, by selecting the main video on the menu screen, the pages of the booklet-type content can be sequentially advanced or returned, and each spread page of the booklet-type content is turned over. You can browse in any format.

  These series of processes are the same as the processes for selecting and playing back a moving image from a chapter list or title list when viewing a movie DVD on a general video playback device. On the (booklet type content) side, it is not necessary to construct a special command or program, and it can be easily realized only with an existing command conforming to a predetermined standard such as a DVD-video format. Moreover, if it is a person familiar with movie DVD, browsing operation can be smoothly performed without being confused by browsing operation of the booklet type content of this invention.

  Further, a predetermined video content playback format such as a DVD video format has a file structure in which the main video and the menu video are stored in separate files. In such a format, the main video and the menu are stored. An upper limit may be set for the video storage capacity in such a way that the main video is larger than the menu video. For this reason, in the present invention, a spread page image using relatively small image data such as a still image is stored as a menu image, and a page turning animation using relatively large moving image data is used as a main image. Since it is stored, it is also suitable for the upper limit of the storage capacity of the main video and menu video with bias.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Depending on the file size, VTS _ ## _ 1. VOB to VTS _ ## _ 9. Files up to VOB exist. ## can be set from 01 to a maximum of 99 for each VTS. In units of 1 GB, VTS _ ## _ 1... VTS _ ## _ 2... VTS _ ## _ 3. The turning moving image data for displaying the three-dimensional page turning animation of the present invention is provided. In these files, a page-turning video from a spread page (menu screen) displayed by the menu actual data of the title ## (VTS _ ## _ 0.VOB) to another spread page (menu screen) that can be transitioned Data is stored (here, “VTS _ ## _ 1.VOB” to “VTS _ ## — 4.VOB”). Furthermore, information on the jump destination after the reproduction of each turning moving image data (main video) is also described. In addition, these files can be displayed on the menu screen displayed by the actual menu data of the title ## (VTS _ ## _ 0.VOB), and display different image data (for example, FIG. 13 and FIG. 14) described later. (VTS _ ## _ 5.VOB or “VTS _ ## _ 6.VOB”) can also be provided. That is, video data that can be reproduced from the menu screen of the title ## is stored in a form organized as VOB files (VTS _ ## — 1 to 9.VOB) having the same title. However, it is not necessarily arranged in this way, and may be stored in a VOB file with a different title. It suffices if it is programmed so that at least the button 52 on the menu screen is operated to reproduce the corresponding moving image data.

The actual data (data content of the VOB file) is divided into smaller cells as shown in FIG. 10, and a unique VOB-ID / cell-ID is attached. The specific configuration is as follows.
VTS (title set number): VTS01_1. VOB VTS02_1. Units such as VOB.
PGC (program chain): Controls playback conditions, time, and playback order of VOB files. The first PGC name in the VMG is defined as “First Play PGC”.
PTT (chapter number): Generally, the chapter of the menu jumps to this unit.
PG (program number): Used as a unit of a playback control program described by a command.
cell (cell number): VOB-ID / cell-ID is designated here for reproduction. In addition, an arbitrary VOB-ID / cell-ID can be designated as the cell number (therefore, depending on the designated contents, the reproduction is not necessarily performed in the order of VOB-ID / cell-ID).

  Returning to FIG. 1, the DVD reader 14 rotates the DVD-video disk 80 placed on a tray (not shown), and among the reproduction data read from the DVD-video disk 80 to be rotated, presentation data (described above). VOB file: data of the main data file or menu data file) is output to the reproduction output unit 10, and navigation data (the above-mentioned IFO file: data of the reproduction control program) is output to the reproduction control unit 15.

  The reproduction output unit 10 reads presentation data read via the DVD driver 18 by a demultiplexer (DEMUX) 10a, and extracts video data, audio data, and the like from the presentation data. The audio decoder 10b decodes the extracted audio data and outputs it to the audio output device 20, and the video decoder 10c decodes the extracted moving image data and outputs it to the display device 30. The sub-picture processing unit 10d decodes the sub-picture, the sub-picture processing unit 10e generates a sub-picture image, and the image synthesis control unit 10f, if necessary, generates the sub-picture image and the video decoder 13 Are combined with the decoded moving image and output to the display device 30.

  The playback control unit 15 performs a playback sequence of digital content (presentation) based on navigation data read via the DVD driver 18 and operation signals input from the main body operation unit 16 and the receiving unit (light receiving unit) 17.

  The image data of each page of the booklet-type content displayed as the menu screen and the moving data of the page turning animation (turning moving image data) are different VOB file data. Therefore, when the display is switched between these, an unnatural position movement, shape change, and size change may occur in the spread page displayed at the break. On the other hand, in the present embodiment, the page turning animation that has received the reproduction input is reproduced and displayed so that the drawing contents can be seen smoothly and continuously from the previous spread page, and is displayed after the page turning animation has been reproduced. The new spread page is also displayed so that the drawn content can be viewed smoothly and continuously from the page turning animation that has been reproduced. That is, the menu screen and the main part playback screen are configured to be taken over so that the drawing contents in the page display area 56A of the booklet type content set on the screen can be viewed smoothly and continuously.

  Specifically, it is displayed between the image data of all spread pages displayed on the menu screen, the first frame of the continuous image frame constituting the flipped moving image data, and the last frame of the same continuous image frame. The display position on the screen 30a is set according to the IFO file corresponding to each image data or moving image data (display position setting means) so that the display position, shape, and size of each page match. Here, in particular, the first frame of the continuous image frame group that forms the page turning animation of the page turning animation displays the same image (same drawing content) as the spread page before the page turning transition of the page turning animation in the content display area. The last frame of the image frame group is an image frame that displays the same image (same drawing content) as the spread page after the page turning transition of the page turning animation in the content display area.

  Returning to the description of FIG. As shown in FIG. 3, the menu screen 50 for the booklet-type content according to the present embodiment operates in a content display area 56A for displaying each page of the booklet-type content and a three-dimensional turning animation, and an area other than that.
