  • Patent number: 9336162
    Abstract: A method is provided for pre-fetching packet data prior to processing. The method accepts a plurality of packets and writes each packet into a memory. A message is derived for each packet, where each message includes a packet descriptor with a pointer to an address of the packet in the memory. Each message is added to a tail of a first-in first-out (FIFO) queue. A pre-fetch module examines a first message, if the first message reaches a first capacity threshold of the FIFO queue. If the first message reaches the first capacity threshold, the pre-fetch module reads a first packet associated with the first message, from the memory, and the first packet is loaded into cache memory. A processor reads the first message from a head of the FIFO queue, and in response to reading the first message, reads the previously loaded first packet from cache memory.

    Abstract: A method for delivering encrypted content to a subscriber terminal on-demand through a communication network is provided. The method begins when SRM receives a request for content from the subscriber terminal. In response to the request, the SRM directs a video server to transmit the content as an unencrypted transport stream to an encryptor. The packets in the unencrypted transport stream include a header with a destination address associated with the subscriber terminal. The encryptor encrypts the content in the unencrypted transport stream to generate an encrypted transport stream. The encryptor also inserts in the packet headers of the packets in the encrypted transport stream the destination address associated with the subscriber terminal obtained from the packet headers in the unencrypted transport stream. Finally, the encrypted transport stream is transmitted to the subscriber terminal over the communication network.

    Abstract: A system for transmitting a transport stream including a robust stream is provided. The transmitting system includes an adaptor for, when receiving a first stream, making a space in the first stream to insert a second stream; a Reed-Solomon (RS) encoder for RS-encoding the input second stream; a Cyclic Redundancy Check (CRC) processor for converting the RS-encoded second stream to a stream comprising an added CRC bit sequence; and a stuffer for inserting the stream to the space in the first stream and outputting a transport stream. Hence, the robust stream can be efficiently transmitted.

  • Patent number: 8566868
    Abstract: A unified system of programming communication. The system encompasses the prior art (television, radio, broadcast hardcopy, computer communications, etc.) and new user specific mass media. Within the unified system, parallel processing computer systems, each having an input (e.g., 77) controlling a plurality of computers (e.g., 205), generate and output user information at receiver stations. Under broadcast control, local computers (73, 205), combine user information selectively into prior art communications to exhibit personalized mass media programming at video monitors (202), speakers (263), printers (221), etc. At intermediate transmission stations (e.g., cable television stations), signals in network broadcasts and from local inputs (74, 77, 97, 98) cause control processors (71) and computers (73) to selectively automate connection and operation of receivers (53), recorder/players (76), computers (73), generators (82), strippers (81), etc.

  • Patent number: 8526609
    Abstract: A system, method and device for real-time compositing of encrypted video streams without having to decrypt each video stream is disclosed herein. A shared encryption key is derived to encrypt multiple incoming video streams to an encrypted master video stream, while retaining full interoperability with popular incumbent video encryption standards. Compositing video is then possible without having to decrypt the master video stream, thereby preserving the security of the copyrighted material. The invention preferably genlocks a digital video source to a master video stream.

  • Patent number: 8509435
    Abstract: Methods and systems for a transport single key change point for all package identifier channels are disclosed and may include descrambling a received transport stream comprising multiple package identifier (PID) channels with multiple key change points, and synchronizing at least a portion of the multiple key change points to occur at a common time. The transport stream may be conditional access or copy protect scrambled. The timing of the key change points may be synchronized by modifying one or more scrambling control bits for the descrambled received transport stream. At least one PID channel in said descrambled received transport stream may be re-scrambled utilizing one or more of the scrambling control bits, and a portion of the PID channels may bypass the re-scrambling. The re-scrambling may include one or more of CP re-scrambling and CA re-scrambling. Each PID channel may be de-scrambled and/or re-scrambled utilizing a separate key.

  • Patent number: 8442110
    Abstract: A method for regulating bandwidth usage in an output data stream transmitted on an analog channel from a cable head end. The output data stream comprises a plurality of input information content signals. For each input information content signal, a series of images are captured, compressed and formed into an input digital data stream. The bandwidth of each input digital data stream is regulated by associating the stream with a current bit allocation total. During each frame time: a bit allocation increment is added to the current bit allocation total for each input digital data stream. When a data packet to be transmitted for an input digital data stream is received by the multiplexer, the data packet is stored.
