I will explain later.

Then, the application and flash content to control the flash (Flash) menu, to incorporate the following mechanism, thereby enabling restoration of the cursor position.

Year by year, Oite to a mobile phone, but it has become a screen configuration with movement in the graphical to be required from the customer, it is necessary to design within the limited memory capacity in the mobile phone. When implementing graphical and moving menus with image data such as bitmap (BMP) data, a large amount of memory is required, but a flash program that can generate vector graphics and animate the images is used. As a result, the memory size can be greatly reduced, and a great variety of menus can be easily created simply by modifying the flash content without changing the program.
However, when various user interface (UI) menus are implemented with flash contents, there is a memory size limitation when changing to another screen by selecting an item in the corresponding menu, and it is necessary to temporarily stop the flash during playback. is there.
For this reason, in a general flash program, since the reproduction of the flash content is started again when the return operation is performed, the cursor position becomes the initial cursor position as shown in FIG.
Therefore, as described above, the control unit 107 according to the present embodiment constructs a mechanism for acquiring the cursor position from the flash content and notifying the cursor position, and realizes the start of reproduction from the intermediate frame.
That is, by incorporating the following mechanism in the application for controlling the flash menu and the flash content, the cursor position can be restored as shown in FIGS.

The following “FsCommand”, “GetURLStream”, “FI “WriteStream” is a flash function, but is not a function prepared for restoring the cursor position.

  The processing outline on the flash content side and the processing outline on the application side are shown below.

<Outline of flash content processing>
<At screen transition>
FsCommand (“device: cursor? Xxxxxxxx”) is described when the cursor moves (when the frame moves).

<When returning to the screen>
LoadVariables ("device: cursor") is described as a process at the time of activation (in the first frame), and the process moves to a frame corresponding to the acquired value.

<Application processing overview>
<At screen transition>
The cursor position is saved by a cursor position save request (device) in FsCommand from the flash engine. Specifically, when “device: kc-cusor? Xxxx” is notified in FsCommand,? The subsequent part (xxxxxxxx) is saved.

<When returning to the screen>
