摘要： Partial pre-encryption with network-based packet sorting. A video-on-demand (VOD) delivery system for delivering encrypted transport streams to incumbent and overlay set-top boxes utilizes a packet picker/duplicator for sorting selected packets from non-selected packets, duplicating the selected packets, and encrypting one of the pair of duplicated selected packets according to an incumbent encryption scheme. A VOD file server stores the transport stream from the packet picker/duplicator. A network sorter sorts the unencrypted selected packet from the non-selected packets and the encrypted selected packet. The network sorter also sorts the encrypted selected packet from the non-selected packets and encrypts the unencrypted selected packets and the non-selected packets according to an overlay encryption scheme and then sends the transport stream to an overlay set-top box. The network sorter is also responsible for combining the non- selected packets and the incumbent encrypted packets and to send the transport stream to an incumbent set-top box.

摘要： The present invention is directed towards providing a partial dual-encrypted stream in a conditional access overlay system. The headend equipment includes an aligner, identifier, and remapper (AIR) device (615) that receives a clear stream and one or two encrypted streams, where the two encrypted streams have been encrypted by two different encryption schemes. The AIR device (615) identifies critical packets associated with the clear stream and subsequently allows two encrypted streams to pass and drops the critical packets of the clear stream. A multiplexer (640) then combines a percentage of the non-critical packets of the clear stream and the critical packets of the two encrypted streams to provide the partial dual-encrypted stream.

摘要： Systems and methods are disclosed for enabling encryptor devices to provide realtime messages having offset cryptoperiods according to an offset algorithm within common crypto-sync pulse boundaries. A master clock aligns the encryptor devices to a common crypto-sync pulse. Subsequently, a cryptoperiod offset aligner assigns a different offset value according to an algorithm to each encrypted service. The corresponding encryptor device then begins the cryptoperiod, during which real-time messages are transmitted, at the assigned offset value from the common crypto-sync pulse.

摘要： Processing an MPEG elementary stream contained in multiple PID streams in a conditional access overlay environment. A multi-program transport stream contains numerous video and audio elementary streams. Critical packets in the elementary streams are encrypted with two different encryption schemes creating a stream having multiple PID values. The streams are then sent from the headend to individual set-top boxes. One encryption scheme can be decoded by the incumbent set-top box and the second encryption scheme can be decoded by the overlay set-top box. The overlay set-top box uses a dual filter system to filter and decode the PIDs for each video and audio stream of the desired program.

摘要： The present invention is suitable for use in a partial dual encrypted system. The present invention allows for two different decryption devices (e.g., an incumbent, or first, set-top and an overlay, or second, set-top) to be located in a single system having an incumbent encryption scheme and a second encryption scheme. Each set-top is designed to decrypt the first or second proprietary encryption schemes, respectively. In accordance with the present invention, the second set-top utilizes a novel program map table to ensure that the second set-top chooses correct elemenentary streams in the partial dual-encrypted stream (i.e., a combined stream including a first encrypted stream, a second encrypted stream, and a clear stream) for a desired program.
