Abstract
The mechanism of a sub-picture processing method for displaying multiple subtitles in a video/audio playing apparatus is provided. The purpose for displaying multiple subtitles in different languages simultaneously can be achieved under a user's control. Due to the unique control procedures and the concept of time division multiplexing, the present invention only employs a single sub-picture decoding unit and a single image mixer to display multiple subtitles in different languages at any preferred positions of the main picture.
