Abstract
A text subtitle decoder includes a text subtitle processor, a text renderer, and a presentation controller. The text subtitle processor parses a text subtitle stream into text data and reproduction control information, where the text data represent a subtitle text to be displayed within a text subtitle region. After the text subtitle stream is parsed, the text renderer renders the text data into bitmap data using the reproduction control information. The presentation controller controls operations of the text subtitle processor and the text renderer.
