Abstract: 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 full screen video in a blended fashion.

Abstract translation: 提供关于说话者的位置以及说出文本时的隐藏字幕信息。 音频/视频信号包括视频数据和隐藏字幕信息。 隐藏字幕信息包括时间索引，隐藏字幕文本和定位信息。 定位信息指示视频数据的帧内的位置，并且与给定时间索引的隐藏字幕文本相关联。 该位置对应于说出关联的隐藏字幕文本的演讲者。 解码器装置对闭路字幕信息进行解码以确定该视频数据内的扬声器的位置，以及将隐藏的字幕文本和定位信息与特定的视频数据帧相关联的时间索引。 视频数据优选地被缩放以提供小于全屏视频。 经缩放的视频被适当地定位在显示屏幕上，并且提供在隐藏字幕文本和扬声器之间提供可视链接的通话气泡优选地从缩放视频中显示出来。 或者，视频没有缩放，并且话音气泡以混合方式叠加在全屏视频上。
