    摘要: A system and method for providing media streaming are provided. A media description file having a range string indicator is used to specify location offsets of a plurality of media fragments within a media file. The range string may be stored directly in the media description file or the media description file may contain an indicator specifying a file containing the range string. The media description file may also include a range unit specifying the size of the offsets in the range string. In an embodiment, offsets within the individual media fragments may also be provided, either in the media description file or in a different file.

    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
