Abstract
Systems and methods for displaying Internet content associated with television programming. Content associated with a program included in the television programming is automatically displayed by a set top box. Before the broadcast of a program, listing information or 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, and the content may 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 the viewer is notified of these links. If both the real time and batch links are available, a determination is made according to pre-defined rules regarding which link is brought to the attention of the viewer.
