Abstract

The present invention relates to a play control method for a digital multimedia file, which comprises the following procedures: the audio, video and text file are relatively played, at the same time, the play level information attached on the above text file is validated; a reference play level information preset in the device is compared with the above validated play level information; according to the comparison result above, a text data in a specified unit and the relative audio and video data are played selectively with an automatic skip. During the play process of the present invention, the text data in the specified unit and the relative audio and video data are skipped automatically according to the play level information in the label information stored as an additional text data. In this way, the text, audio and video content which not suitable for children or teenagers can be skipped according to the text data in specified unit, and therefore the control action of the age limit level for the digital multimedia file such as the DIVX file can be partially performed.

Description
