Abstract: A method for managing access to scrambled broadcast or transmitted events received from a variety of service providers (including broadcast television networks, cable television networks, digital satellite systems). Each service provider employs the same public key for descrambling the access information message thereby permitting a user to access events from various service providers without changing the smart card. The method may also be expanded to manage access to a scrambled package of broadcast events.

Abstract: A system for generating a signal for coupling digital audio, video and data signals in compressed form via a bus. A processing means formats the digital audio, video and data signals into superpackets for transmission via the bus. Each superpacket comprises a timestamp, and a transport packet, representative of the digital audio, video and data signals. The superpackets have a fixed duration and occur at variable intervals. Devices receive the superpacket signal and may utilize the timestamps for clock synchronization. A recording and replay device processes the variable superpacket signal occurrence for recording. Reproduced timestamps are utilized to control restoration of the superpacket signal to have substantially the duration and occurrence as when formatted for bus transmission. A simplified bus couples superpackets between devices. An indicia is added to a superpacket signal to provide automatic control of device bus interfaces.
