Abstract
A system and method for adding hyperlinked information to a television broadcast in which an interactive content icon is used. The broadcast material is analyzed and one or more regions within a frame are identified. Additional information can be associated with a region, and can be transmitted in encoded form, using timing information to identify the frame with which the information is associated. A receiver displays the annotation information associated with the video signal in response to a viewer request on a frame by frame basis. The interactive content icon can be used to inform a viewer of the presence of hyperlinked information, for teaching the viewer how to use the system, and for informing the viewer about the hyperlinked information.
