Abstract

An interactive television system is provided with an interactive information system by which channels or services interact together. The information system provides informational messages that prompt a user to select an associated channel or service. If selected, the system transfers control to the selected channels or services. If necessary, information associated with the informational messages is provided to the selected channel or service. In a preferred embodiment the informational messages are sequentially displayed video segments. The video segments may be associated with other channels or services in the interactive viewing system. The user may use an input device, by depressing a single button, and launch another channel or service that is associated with the currently displayed video segment.

Claims

1. An interactive viewing system having a head end in two-way communication with a plurality of viewer stations, the viewer stations having a video display operatively coupled to a controller and an input device for providing user commands to the controller, the interactive viewer system allowing a user to selectively launch at least one of a plurality of applications, the system comprising:

a first memory located at the head end for storing a script database, the script database adapted to provide an order that video segments are to be displayed on the video display; and

a second memory located at the controller for storing the script database;

the controller adapted to transfer the script database from the first memory to the second memory and adapted to interpret the script database to determine a video segment to be displayed and to retrieve from the head end the video segment, the controller further being adapted to display the video segment on the video display and to respond to a command input through the input device to launch an application associated with the currently displayed video segment and to transfer a parameter associated with the currently displayed video segment to the launched application.

2. The interactive viewing system of claim 1 where the controller is adapted to transfer bitmaps from the first memory to the second memory and to concurrently display a bitmap and the video segment on the video display.

3. The interactive viewing system of claim 1 where the script database is a hierarchical database including timing information related to a length of the video segment.

4. The interactive viewing system of claim 1 where the parameter transferred is a title of the currently displayed video segment.
