摘要： A source generates a medium key (KM) and a media secret table including a plurality of entries, each entry including (KM) encrypted by a public key (PU-PD) of a plurality of devices, obtains the medium ID of a medium therefrom, generates a content key (KD) for a piece of content, encrypts the content with (KD) to result in (KD(content)), encrypts (KD) with (KM) to result in (KM(KD)), generates a package for the content including (KD(content)), (KM(KD)), the medium ID, and a signature based on at least the medium ID and verifiable with (KM), and copies the generated package and the media secret table to the medium. Thus, a device with the medium and a private key (PR-PD) corresponding to an entry of the media secret table can access and render the content.

摘要： Enabling efficient navigation of a playlist of media files stored on a computer-readable medium. Aspects of the invention define a playlist structure to have one or more playlist units. Each playlist unit identifies one or more media files in the playlist and includes metadata for the media files. A consumer electronic device retrieves the playlist units and displays the metadata contained therein to a user to enable navigation of the playlist. Aspects of the invention reduce the memory requirements of the consumer electronic devices and reduce the quantity of disk seek operations needed for playlist navigation.

摘要： Updating automatically generated playlists in response to media content being edited. Aspects of the invention associate a playlist type or other code with each playlist to define the structure of the playlist. When media content is added to or deleted from a collection of media files, one or more playlist types corresponding to the media content are identified. The playlists with the identified playlist types are updated to reflect the addition or deletion of the media content.

摘要： Creating and displaying an adaptive menu structure for media files. The invention includes authoring software to create the menu structure to enable a user to navigate the media files using a media player. The invention also includes filtering software to adapt the created menu structure to display menu information on a display associated with the media player as a function of a media type associated with the media player. In one embodiment, the invention is operable as part of a compressed media format having a set of small files containing metadata, menus, and playlists in a compiled binary format designed for playback on feature-rich personal computer media players as well as low cost media players.

摘要： Storing image data for a menu in a compound image file. Image data for a menu of media files is retrieved and efficiently stored in the compound image file. A media player accesses the compound image file to obtain and display relevant images in a menu. The invention reduces the quantity of file operations needed to render the menu and thus reduces the time needed to display the menu as perceived by a user. As a result, the invention enhances the user experience with the media player.

摘要： Methods for streaming web content data via a computer-readable medium. The web content data comprises one or more media samples. The media samples are encoded in a streaming media format as a web component stream. The web component stream is combined with other component streams comprising additional data other than web content data into a presentation stream. The presentation stream is transmitted via a media server to a client. Rendering commands, which are included in one or more rendering samples encoded in the web component stream along with the media samples, coordinate synchronization between the media samples and the additional data when the client renders the presentation stream.

摘要： Enabling the automatic identification of participants to a common event to enable data sharing between the participants. An event identifier embedded in the content data associates the content data with an event. A content data service maintains a list of event identifiers and a list of participants associated with each event. Each of the participants communicates with the content data service to identify the other participants. The participants communicate with each other to share content data from the common event.
