A METHOD AND APPARATUS FOR HYPERLINKING IN A TELEVISION BROADCAST

摘要

The invention features a system and method for adding hyperlinked information to television broadcast system. The system includes a video source providing video information and an annotation system. The annotation system generates annotation data to be associated with the video information and generates annotation data timing information. The hyperlinked broadcast system also includes an augmented video information transmission generator that receives the annotation data, the video information, and the annotation data timing information. The augmented video information transmission generator generates an augmented video transmission signal including the annotation data, the annotation data timing information and the video information. In operation, the augmented video information transmission generator associates the video information with the annotation data using the annotation data timing information. A receiver displays the annotation information associated with the video signal on a frame by frame basis.
