ABSTRACT:
An interactive video services system for enabling store and forward distribution of digitized video programming is disclosed. In accordance with a feature of the present invention, encoded and compressed digital video signals are transmitted via satellite link from a centrally located uplink site to a plurality of hospitality establishments, where the digitized video programming is stored in the memory of a video server computer or is transmitted "real-time" to the hospitality establishment's customers. The establishment either has its own downlink facilities or shares downlink facilities with other hospitality establishments. The uplink facility and satellite can transmit a variety of video signals--including video signals for real-time viewing by customers, compressed video signals for storage and subsequent retrieval and viewing by customers, and other types of digitized data, such as advertisements and barker screens. Various signal types, including operating system updates and digitized menus and advertisement graphics for the video programming, are separated and appropriately processed and routed at the hospitality facility.
