- the document data structure constructing unit 5 changes the “Museum of Yamada Village” and “Museum of Kawakami Village” alternately to be displayed on the screen of the TV 2 based on the signal transmitted by the periodic signal transmitting unit 71.
- the attribute value of the visibility attribute in the DOM tree may be changed. For example, as shown in FIG.
- the internal document data structure constructing unit 5 is configured to display the “Yamada Village Museum” on the TV 2 screen when the periodic signal transmitting unit 71 transmits an even-numbered (odd-numbered) signal.
- the attribute value of the visibility attribute is changed based on a script that is the content of the document header section 102 of the document data 100. Also, in the above case, regardless of whether “Museum of Yamada Village” or “Museum of Kawakami Village” is displayed on the screen of TV 2, as described with reference to FIG.
- the internal document data structure structuring unit 5 may be made to function so as to change the DOM file in accordance with the pressing operation of the button “1” or “2”.
- two nodes that are displayed in the same place are prepared, one visibility attribute is set to visible, and the other visibility attribute is set to hidden, so that only one is displayed.
- the display was switched alternately by alternately switching the visibility attributes of each, three or more nodes displayed at the same location may be prepared. In this case, the visibility attribute of one node If the visibility attribute of other nodes is set to hidden and the visibmty attribute value is arbitrarily switched at the transmission timing of the periodic signal, a rich display switching can be achieved.
- the document data 100 is assumed to be composed only of (1) the document body data 101 described above.
- the document data 100 may be composed of the (1) document body data 101 and the (2) image image file and Z or the (3) graphic image file. Good.
