The present invention is an interactive computer system which may operate on a computer network. Subscribers interact with a fully interactive programthrough the use of input devices and a personal computer or a television. The multiple video/audio datastreams may be received from a broadcast transmission source or may be resident in local or external storage. In response to user inputs, a personalized graphics, video and/or audio presentation is provided to the user either immediately or at a later time. If not presented immediately, the interactive computer system utilizes "trigger points" to determine when to enable multiple multimedia segments during the show. The CPU uses embedded or stored authoring commands for integrating the various multimedia elements. The interactive multimedia computer enables seamless flicker-free switching from one signal to another on the same or different channels.
