Abstract: The system supports monitoring of receiver network status by providing an email return path for receiver status information. Remote locations provide access to an internet capable LAN, which the integrated receiver decoders use to send parameter information to the central server using the internet protocol. Unit status and parameter information is sent in a binary format using standard email protocols to transfer the data. The server translates the binary data and stores the receiver status, allowing the user to browse the latest status of any receiver which has sent back a report.

Abstract: A satellite broadcast conditional access system with key synchronization uses indexing of an authorization stream to quickly restart the decrypting process after short carrier fades and after carrier switches. The authorization stream includes cyphered seeds and index numbers which are sequentially sent to a group of receivers. The same authorization stream can also be broadcast multiple times to the group of receivers. A conditional access server selects a starting index number and increments the index number by a predefined value. The receivers have a memory to save the current index number for the authorization stream. Any receiver that loses its connection to the broadcast and thereafter reestablishes its connection can retrieve the latest index number being issued in the authorization stream and compare it with the stored index number. When the index numbers match or are within a defined threshold, the receiver will continue to decypher the seeds and decrypt the transport stream.

Abstract: A central controller remotely controls and configures sets of receivers to receive programs in a broadcast signal and recast selected sets of programs to selected sets of media devices over a computer network. Each receiver has an input module that receives programs from the broadcast signal, a control module that receives a control stream from the central controller, and a recasting module that reformats and transmits selects programs over the computer network. The receivers use the control stream to configure the selected sets of programs and the selected sets of media devices. The recasting module is uncoupled from the control module so that the receiver's recasting of selected program content can be different for different sets of receivers, thereby allowing any combination of broadcast programs to be recast by any set of receivers to any set of media devices. The receiver also has a storage module and interrupts the live recasting of the broadcast signal to spool out a locally stored file.
