    摘要: Embodiments of reversible systems and methods for fast, secure and efficient transmission, storage, and protection of digital multimedia are disclosed. The embodiments may have the ability to simultaneously compress and encrypt digital data in order to concurrently reduce data size and prevent reconstruction without the proper encryption key. Embodiments of a method may include pre-processing data to optimize the size of data segments to be compressed, transforming the data for improving the compressibility of the before-mentioned data segments, processing the data sequentially to generate predictive statistical models, encoding the data for simultaneously encrypting and compressing data segments using a keystream, and increasing both the compression ratio and security of these encoding processes using a block cipher. Embodiments of these methods may be suitable for use on both encrypted and unencrypted media.

    摘要: A video data extension system includes a transmitter and a receiver for transmitting and receiving encoded serial data. Transmitter is configured to receive one SDI 3G video stream at 2.97 Gb/s, two HD-SDI video streams at 1.485 Gb/s, two SD-SDI at 270 Mb/s, or one HD-SDI at 1.485 Gb/s and one SD-SDI at 270 Mb/s. Received data is segmented into packets to form an extended video stream for transmission at 3.75 Gb/s. To each packet, idle and header are provided. Data such as RS422 data may be included in the extended video stream. Where the received data includes data from two HD streams, received data are segmented into two groups of data packets for arranging into extended video stream in an alternate manner. Upon receiving the extended video stream, receiver uses idles to align data and header information to separate the HD streams.

    摘要: The application describes a technique of synchronizing a digital video signal for transmitting it in the uncompressed form via a synchronous hierarchy network having its internal clock, by standard frames of the network. The technique comprises steps of obtaining the video signal as a Serial Digital Interface (SDI) signal having its initial video clock and presenting a succession of video frames, storing said video signal, using the video clock, in a buffer memory having capacity of one or more complete video frames, reading said video signal from the buffer memory using a transport clock derived from the internal clock of the synchronous hierarchy network.
