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.
