摘要:
Closed captioning information is provided regarding the location of a speaker, and when the text is spoken. An audio/video signal includes a video data and the closed captioning information. The closed captioning information includes a time index, a closed captioning text, and positioning information. The positioning information indicates a position within a frame of the video data, and is associated with the closed captioning text for a given time index. The position corresponds to the speaker who is speaking the associated closed captioning text. A decoder device decodes the closed captioning information to determine the position of the speaker within the video data, and the time index to correlate the closed captioning text and positioning information to a specific frame of video data. The video data is preferably scaled to provide a less than full screen video. The scaled video is appropriately positioned on a display screen and talk bubbles, which provide a visual link between the closed captioning text and the speaker, are preferably displayed off the scaled video. Alternatively, the video is not scaled and the talk bubbles are superimposed on the fall screen video in a blended fashion.
