ABSTRACT:
Displaying content associated with a television program using logical addresses identifying the content. Content associated with the television program is automatically displayed by a set top box. Before the broadcast of a program, television listing information, such as EPG data, is stored at the set top box. The listing information includes batch mode logical addresses or links. During the program, a viewer is notified about the link, enabling the content to be accessed and displayed concurrently with the program. In addition, real-time logical addresses or links, which are embedded in the program, may be extracted and displayed to the viewer. If both the real-time and batch mode links are available, a determination is made according to pre-defined rules regarding which link is brought to the attention of the viewer. In this manner, real-time links can be supplied with the broadcast to supplement or replace the batch mode links.
