    摘要: In one embodiment, a method of adaptive media streaming includes receiving a cipher media stream at a media device. The cipher media stream is compliant with a media compression standard. The cipher media stream is decrypted and decoded using an inverse stream cipher algorithm and a compressed media stream is generated by combining the cipher media stream with a keystream.

    摘要: In one embodiment, a method of streaming media includes partitioning a media stream to be transmitted into a first stream of media segments at a media server. The first stream of the media segments has a first sequence. An index table is generated to identify the first sequence of the first stream of the media segments. The index table is encrypted using a key. A second stream of the media segments is generated. The second stream has a second sequence, which is random relative to the first sequence. The encrypted index table and a transcoded media stream having the second stream of the media segments are transmitted.

    摘要: The media player employs an operating system that supports a virtual machine into which auto-run playback programs may be loaded and run. The auto run playback program is stored on the media containing the program content, such as on an optical disc medium. When the medium is inserted in the player, the auto run playback program automatically launches and is thereafter used to access playback the media content. Support for legacy media is provided to allow the player to playback compact discs and DVD discs that were manufactured without the auto run playback program

    摘要: A method is provided for enhanced spread spectrum watermarking. The improved watermarking method includes: receiving host data which is expressed in a transform domain by a plurality of host transform parameters; reducing variance between the plurality of host transform parameters, thereby forming an enhanced sequence of host transform parameters; and adding a watermark to the enhanced sequence of host transform parameters using a spread spectrum technique. The enhanced sequence of host transform parameters may be formed by arranging the plurality of host transform parameters in at least one of an ascending order or descending order; determining a difference for each pair of consecutive host transform parameters; and alternating the sign of every other difference value, thereby forming the enhanced sequence of host transform parameters.

    摘要: A method and system for hiding authentication data within a multimedia data stream provides for cross-authentication. The method includes the step of obtaining a first set of authentication data, where the first set of authentication data is based on data contained in a first media channel of the multimedia data stream. The method further includes the step of hiding the first set of authentication data in a second media channel of a multimedia data stream. When dealing with active data streams, the present invention provides for hiding a first subset of the active data stream in a visual channel of the multimedia data stream. A second subset of the active data stream is then hidden in the audio channel of the multimedia data stream. In one embodiment, the first subset includes executable content, where the second subset includes a controlled data stream.
