<p>A method for object-based video description and linking is disclosed. The method constructs a companion stream for a video sequence which may be in any common format. In the companion stream, textual descriptions, voice annotation, image features, URL links, and Java applets may be recorded for certain objects in the video within each frame. The system includes a capture mechanism for generating an image, such as a video camera or computer. An encoder embeds a descriptive stream with the video and audio signals, which combined signal is transmitted by a transmitter. A receiver receives and displays the video image and the audio. The user is allowed to select whether or not the embedded descriptive stream is displayed or otherwise used.</p> |
