    摘要: Secure presentation of media streams includes encoding the media streams into digital content, encrypting a portion of that digital content, the portion being required for presentation, in which the encrypted version is substantially unchanged in formatting parameters from the clear version of the digital content. Selecting those portions for encryption so there is no change in distribution of the media stream: packetization of the digital data, or synchronization of audio with video portions of the media stream. When encoding the media stream into MPEG-2, refraining from encrypting information by which the video block data is described, packet formatting information, and encrypting the video block data using a block-substitution cipher. A block-substitution cipher can be used to encrypt each sequence of 16 bytes of video data in each packet, possibly leaving as many as 15 bytes of video data in each packet in the clear.

    摘要: A home theater system includes construction, presentation, and commerce in, songs. Presentation includes at least one of: metadata about songs or sounds, a function capable of transitioning from one song to a next song, and user preferences; and can determine in what manner to transition from one song to a next song. Construction of songs includes either factors above, or at least one of: a function or a user extension capable of selecting a next song, and an element capable of determining whether the song is perceptually random. A user interface is capable of searching playlists and selecting them for presentation, representing each playlist with a substantially unique pictorial representation, distinguishing in presentation between those playlists licensed to the user and those that are not, and capable of substantially immediate purchase of playlist licenses either individually or in bulk and either automatically or with minimal intervention.

    摘要: Selection and presentation of media streams, in which presentation is not limited by order imposed by the digital content representative of those media streams, in response to bookmarks and watchpoints settable and usable by a user. Bookmarks reference a location within the media stream, not necessarily pre-selected and possibly dynamically selected, in which a presentation can be started or restarted therefrom. Watchpoints reference a location within the media stream, or a presentation state for the media stream, in which an action can be triggered thereby. Bookmarks and watchpoints provide a general technique for presenting selections from media streams in response to metadata.
