摘要： An encryption arrangement for multiple encryption of television programs. A system according to embodiments of the present invention multiple encrypts only a portion of the data required for full presentation of a television program to permit coexistence of multiple conditional access encryption systems associated with multiple manufacturer's set-top boxes within a single system. In one embodiment, a time slicing technique is used to encrypt portions of a program on a time allocated basis. By only encrypting a portion of the program, dramatically less bandwidth is consumed than the alternative of multiple encryption of all program data, thus permitting a larger number of programs to be carried over the same bandwidth while permitting coexistence of multiple conditional access systems in a single cable television system.

摘要： A selective encryption decoder for decrypting and decoding a selectively encrypted digital video signal has a demultiplexer that receives packets of digital video, certain of the packets being unencrypted and certain of the packets being encrypted. Certain of the encrypted packets carry data representing an active region of a video frame. The unencrypted packets have a first packet identifier (PID) and the encrypted packets have a second packet identifier (PID). A decrypter receives the encrypted packets having the second PID and decrypts the encrypted packets using a first encryption method to produce decrypted packets. A PID remapper changes at least one of the first and second PIDs so that the unencrypted packets and the decrypted packets have the same PID. A decoder decodes the unencrypted and decrypted packets to produce a decoded video signal. This abstract is not to be considered limiting since other embodiments can include more, fewer or different features than those described in this abstract.

摘要： A selective encryption encoder has a packet identifier that identifies packets of a specified packet type forming a part of a program. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. A PMT (program map table) inserter generates temporary identifying information that identifies the first and second sets of identified packets inserts the temporary identifying information as user private data in a program map table (PMT) forming a part of the transport program specific information (PSI). The data are then sent to and received from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method. The PSI is then modified at a PSI modifier to remove the temporary identifying information and to correctly associate the first and second sets of identified packets and the unencrypted packets with the program.

摘要： A selective encryption encoder consistent with certain embodiments of the invention has vertical and/or horizontal stripes encrypted. In one embodiment, packets are examined in the digital video signal to identify a specified packet type, the specified packet type being both packets carrying intra-coded data representing a pattern of horizontal stripes across an image and packets carrying intra-coded data representing a pattern of vertical stripes across an image. The packets identified as being of the specified packet type are encrypted using a first encryption method to produce first encrypted packets. These first encrypted packets are then used to replace the unencrypted packets in the digital video signal to produce a partially encrypted video signal. The packets of the specified type can also be multiple encrypted and replaced in the data stream to produce a multiple encrypted video data stream. This abstract is not to be considered limiting since embodiments consistent with the present invention may incorporate more, fewer or differing elements than mentioned in this abstract.

摘要： According to one embodiment of the invention, a configurable CableCARD adaptable for use by multiple conditional access (CA) providers. CableCARD comprises core logic configured to descramble incoming scrambled content, a first CA logic block and a second CA logic block. Connected to the core logic, the first CA logic block uses a first CA function associated with a first CA provider. The second CA logic block is also connected to the core logic. The second CA logic block uses a second CA function associated with a second CA provider. Where the incoming content is scrambled according to the second CA function, the connection between the first CA logic block and the core logic is disabled.
