Abstract
A method for processing a z-index of an SMIL(Synchronized Multimedia Integration Language) document in a mobile terminal is provided to implement overlap effect of media by forcibly preventing refreshing of a screen while reproducing an image. A SMIL document is inputted to a RAM. The SMIL document is parsed. A structure of the parsed document is analyzed to generate a data structure including reproduction start and end information of each media. When media to be displayed in parallel are found, the order of display of the media is determined according to a z-index. The media is reproduced at a point determined according to a media reproduction data structure. If the media is to be processed in parallel and includes an attribute of the z-index, screen refreshing is forcibly stopped. If the media does not have the attribute of the z-index, it is reproduced and then the screen is refreshed.

Portable terminal is owing to be subjected to the limitation of memory, file system, main arithmetic unit etc., playing image, audio frequency simultaneously can appear being difficult to, the situation of multi-medium datas such as video, therefore generally after having shown medium on the picture, picture is refreshed next medium in order on picture, to show.That is, show medium after, in order to show other medium in the relevant range, play new media again after removing dependent picture.
Therefore, when definition SMIL file when on picture, showing a plurality of medium simultaneously, or when in playing device, using background, the overlapping demonstration of prospect medium based on the z-index, because refreshing automatically of terminal, the shown data of last picture disappear (medium that the z-index value is little), thereby can't show because the excessive effects that the z-index produces.
As mentioned above, when in the past portable terminal when the same area shows overlapping medium (image, activity video etc.), after having shown medium, show before next medium, carry out picture refreshing, so data presented disappears before, can't show the excessive effects that the z-index of SMIL file is brought.
Summary of the invention
In view of the above problems, the object of the present invention is to provide the z-index process method of SMIL file in a kind of portable terminal, it is when resolving the SMIL file, in addition structuring of the data that media play is relevant, behind z-index adjustment DISPLAY ORDER, when needs are handled a plurality of medium simultaneously side by side, according to the played in order image of above-mentioned adjustment, simultaneously mandatoryly forbid refreshing of picture, thereby can show the excessive effects that the z-index is brought.
For achieving the above object, feature of the present invention is to be made of following several steps: step 1, resolve the SMIL file be kept in the portable terminal, and generate and include that the broadcast about each medium that above-mentioned file comprises begins and the data structure of ending message; Step 2 if having the z-index attributes in the above-mentioned data structure, exist to need the medium that show simultaneously, then according to the playing sequence of associated order structures shape medium; Step 3, the playing sequence according to the medium of above-mentioned decision begins to play in turn from the medium with minimum priority, after each media play finishes, forces to forbid carrying out picture refreshing simultaneously.
Feature of the present invention is also to comprise such step: the medium that above-mentioned needs show simultaneously are the medium that define in the field arranged side by side of SMIL file, utilize the z-index value of related media information, begin to the high higher demonstration priority of end decision from being worth a low end.
