An interactive entertainment network system supplies previews in an analog format while operating in a video-on-demand (VOD) mode. The previews are displayed instantaneously when a viewer switches to a designated VOD channel. The previews are played in a continuous loop to attract viewers that are switching through channels. The VOD channel therefore appears like traditional broadcast channels, as opposed to a still screen. In this manner, the viewer will be less inclined to skip past the VOD channel. If the viewer does nothing, the previews of the new releases cycle through, one after another. No digital resources are utilized to this point; rather, the analog video stream is continually transmitted in a "broadcast" fashion. However, if the viewer actively requests information or a new set of previews while in the VOD application, the system ceases the analog presentation and transitions to a fully interactive digital system. Any requested programs or other information is supplied from the headend in a digital format. After a period of inactivity, the system reverts to playing the analog video stream of previews to further conserve digital resources.

[ I claim:] [1.] In an interactive entertainment network system in which a content provider serves video content programs to one or more user interface units over a distribution network, the content provider having a storage medium to store the video content programs and associated preview video trailers about the video content programs in digital format, a system comprising:a video processing unit at the content provider to convert preview video trailers from the digital format to an analog format and thereby form an analog video stream for transmission to the user interface units;the video processing unit being configured to determine a schedule of the preview video trailers for transmission to the user interface units, the schedule defining an order that the preview video trailer appear within the analog video stream to be supplied to the user interface units; andan on-demand application resident at a user interface unit to display the analog video stream when the user interface unit initially executes the on-demand application and to generate requests for services from the content provider in response to user input; andthe video processing unit, in response to receiving a request from the on-demand application, outputting the preview video trailers and video content programs as digital video data streams.
