[0022]
This apparatus / method includes a video playback unit 10 for generating a video window, a note screen generation unit 14 for generating a note window, and a second note (term) for generating another note window (term window). A screen generator 18 is provided. If necessary, a third note screen generator may be provided. A plurality of notes may correspond to one video. For example, note 1 and note 2 may correspond to the video.
[0023]
The video playback unit 10 receives a control signal from the control unit 11, reads predetermined data from the video memory 12, plays it back as a moving image, and outputs it to a display device (not shown). The video reproducing unit 10 can read data of an arbitrary part by designating the address of the video memory 12. Therefore, the video can be played back from the beginning, or can be played back in the middle, or can be freely operated such as fast forward and rewind. The video playback unit 10 can output audio along with video. In the following description, in the case of video, in principle, audio is included together with video.
[0024]
In the video CD, each chapter is a single file. Therefore, the time axis can be moved by reading a file in the video CD. On the other hand, in the case of DVD-Video, a plurality of chapters are made into one file. In this case, a time axis moving method is used, for example, after XX seconds of the number of chapters by referring to the file in which the index information is written.
That is, as a search method at the time movement of video, (1) a method of directly specifying a file and time such as this time of this file and (2) a time position by referring to an index file There are two types of search methods.
[0025]
The note screen generation unit 14 receives a control signal from the control unit 15, reads predetermined data from the note memory (text data is stored in advance) 16, generates a note screen, and outputs it to a display device (not shown). The note screen generation unit 14 can select and display an arbitrary portion of data by designating the address of the note memory 16.
[0026]
The second note (term) screen generator 18 reads predetermined data from the second note (term) memory 19 and outputs it to a display device (not shown). The second note (term) screen generation unit 18 can select and display data of an arbitrary portion by designating the address of the second note (term) memory 19.
[0027]
The apparatus / method according to the embodiment of the present invention includes a video-note correspondence table 13 between the video reproduction unit 10 and the note screen generation unit 13, and a note screen generation unit 14 and a second note (term) screen generation unit. 18 is provided with a note-note correspondence table 17. The table 13 is for synchronizing between the video screen and the note screen. That is, when a video screen designated by the control unit 11 is displayed, a note (text) corresponding to the video screen is displayed on the note screen. Conversely, when a note screen designated by the control unit 15 is displayed, a video corresponding to the note screen is displayed on the video screen.
[0028]
On the other hand, when the note screen designated by the control unit 15 is displayed, text corresponding to the note screen is displayed on the second note (term) screen (for example, when the pointer indicates specific text on the note screen, A description of the content of the text) is displayed. Note that control in the reverse direction, that is, control from the second note screen to the note screen is not particularly necessary (of course, it may be provided).
[0029]
FIG. 4 is an explanatory diagram of a (a) video-note and (b) note-note correspondence table in the embodiment of the present invention. The video-note correspondence table 13 stores in advance the relationship between the video time (for example, recorded in seconds with the first part of the video being zero) and the text of the corresponding note. For example, when the video at time t1 is played, the contents of TEXT.htm # 5 are displayed in the note window. Note that the video-note correspondence is not limited to one-to-one. Multiple notes may correspond to one video. For example, note 1 and note 2 correspond to the video. In this case, when the video is reproduced, the contents of the note 1 and the contents of the note 2 corresponding to the video are displayed, and when a certain part of the note 1 is referred to, the corresponding video and the note 2 are displayed. It is also possible.
[0030]
The note-note correspondence table 17 stores text relationships in advance for each note window. For example, when the text of TEXT1.htm # 1 is displayed in the note window, the text of TEXT2.htm # 1 is automatically displayed in the related note window, and mokuji.htm # is displayed in the related table of contents window. 1 text is automatically displayed. In other words, tags are embedded in important points in each note, and the table stores the correspondence between tags. TEXT1.htm # 1 and the like are names associated with a part of one text file, but may be configured as an independent text file.
[0031]
By referring to the parts # 1, # 2, # 3,..., A specific part in the same TEXT1.htm file can be displayed. For example, when jumping to TEXT1.htm # 3 while displaying TEXT1.htm # 1, the displayed HTML file is scrolled accordingly.
[0032]
Here, it will be described that the correspondence between video and notes in the video-note correspondence table 13 is not one-to-one. In other known systems, for example, a karaoke system in which lyrics are displayed together with video, there is a one-to-one correspondence between video and notes, and both are handled as a unit. However, the apparatus / method according to the embodiment of the present invention is a teaching material, an educational device, or a product explanation device, and the relationship between video and notes is not necessarily one-to-one. For example, the same text may be referred to repeatedly in a lecture or may be referred to by ignoring the text order. This correspondence is such that a part of the text is repeatedly referred to in random order as time passes such as a lecture. Therefore, as will be described later, a special device is required when referring to a video from text.
[0033]
