Abstract
A programming-on-demand cable system is provided which allows any one of a plurality of individual users to request anyone of a plurality of video programs they wish to view from a library of programs, and permits the requested program to be available for viewing on a conventional television set at the user's location following a request initiated by the user. Each program is preprogrammed in a memory device selectable by a host computer at a central data station in response to an address signal transmitted from the user. The host computer in conjunction with other electronics transmits the video program at a high non-real-time rate over a fiber optic line network to a data receiving station at the user's location. The data receiving station then converts the received optical data back to electrical data and stores it for subsequent real-time transmission to the user's television set. The system permits the user to view any one of a number of programs transmitted on a non-real-time basis, and also allows the user to store the transmitted program at his data receiving station for an indefinite period of time for viewing at a later date. A method is also provided for transmitting the programs on a non-real-time basis.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
