Abstract
An interactive presentation system receives a plurality of series of digital data segments (e.g., image frames), each series of digital data segments appearing at the video presentation system on a repetitive, cyclic basis. Each digital data segment includes a first data portion from which an image can be constructed and a second data portion which includes information relating to the image and further includes, if required, information which links an active area of the image to another data source. The system includes an interface for receiving the repetitively transmitted series of digital data segments and a switch for selecting at least one of the received series of digital data segments. A display presents an image that is constructed from the first data portion of a data segment that is included in a series of digital data segments. A processor is responsive to a user's selection of an active area on a displayed image to employ information from the second data portion that is associated with the displayed image to operate the switch to access another data source. The other data source can be another data segment, a video presentation, or an audio presentation. The video presentation system is operable without requiring a reverse channel for communications with the transmission head end.
