Method and apparatus for processing and displaying multiple captions superimposed on video images

摘要

Methods and apparatus for processing and displaying caption information associated with a video program are provided. The caption information is extracted from a video signal and different captions are rendered in sequence for different segments of the video program. A plurality of the different captions is blended in a form for simultaneous display superimposed on video images during one of the different segments of the video program. The different captions may be the latest caption corresponding to the current segment of video and a previous caption corresponding to a previous video segment. These different captions can be displayed such that they overlie each other and such that their opacity is different. In this manner, a viewer is able to have a prolonged period of time to read captions and can readily distinguish the current caption from the previous caption.
