Initiating interactivity with a received enhanced digital TV program that is being displayed in full screen mode without obstructing the existing views of the TV program. The method includes displaying a video component of the enhanced digital TV program in a full screen mode on a display, extracting information related to a broadcaster's station ID from a data component of the enhanced digital TV program, displaying the station ID in a changed appearance on the display according to the information, and accepting a viewer input selection to enter an interactive mode in response to the changed appearance. The station ID may be represented in a changed appearance only when new ancillary digital content is received as part of reception of the enhanced digital TV program. As a result of the viewer input selection, display of the ancillary digital content of the TV program on a portion of the screen may result. |
