Abstract
An interactive video services system for enabling store and forward distribution of digitized video programming comprising merged graphics and video data from a minimum of two separate data storage devices is disclosed. In a departure from the art, an MPEG converter operating in tandem with an MPEG decoder device that has buffer capacity merges encoded and compressed digital video signals stored in a memory of a video server with digitized graphics generated by and stored in a memory of a systems control computer. The merged signals are then transmitted to and displayed on a TV set connected to the system. In this manner, multiple computers are able to transmit graphics or multimedia data to a video server to be displayed on the TV set or to be superimposed onto video programming that is being displayed on the TV set.
