Abstract: A user interface for use with a content items delivery apparatus and method which simulates the look and feel of a video rental store. Rental of the content items occurs within an online environment including one or more client computers and at least one network server connected by a communications link to the one or more client computers. The method includes providing access to an online catalog stored within a memory of a network video server computer and displayed on a main website. The online catalog includes information regarding digital video signals available for rental from the network server computer. The digital video signals may be displayed as virtual video boxes on a virtual carousel or on virtual shelves. The user may select a digital video signal and purchase a license to view the selected digital video signal based on an access level selected by the user.

Abstract: The present invention overcomes the problems in the existing art described above by providing an online digital video signal transfer apparatus and method. Rental of the digital video signals occurs within an online environment including one or more client computers and at least one network server connected by a communications link to the one or more client computers. The method includes providing access to an online catalog stored within a memory of a network video server computer. The online catalog includes information regarding digital video signals available for rental from the network server computer. Requests are then received from client computers for rental of digital video signals selected from the online catalog for a specified period of time. The requests include electronic payment based on the selected digital video signal and the specified period of time. Once electronic payment is provided, the digital video signal is transmitted to the client computer via communications link.

Abstract: A system protocol for the composite shift key communication of binary signals in which a transmitting transceiver transmits a first summed signal having a first qualifying signal at a qualifying signal frequency Wqt as one of the summed signal components only when a binary signal is desired to be transmitted. The transmitting transceiver ceases transmission of the first qualifying signal Wqt as a transmitted signal or as a component of a composite summed signal when neither a binary zero nor a binary one is desired to be transmitted. The receiving transceiver signals to the transmitting transceiver when the binary signal transmission is being successfully received by transmitting thereto a second qualifying signal Wqr. The receiving transceiver drops the transmission of the second qualifying signal Wqr when the binary signal transmission is not being successfully received, or is being received with perceived errors therein.
