摘要:
In a digital signal recording and reproducing apparatus, a signal obtained by multiplexing an audio signal on a bit rate reduction encoded video signal is delivered as a transmission signal. The transmission signal is multiplexed with a data showing its content, such as a copy number of times data and an edit number of times data. Depending on the state of reproduction at a reproducing side apparatus, which is a source side of transmission, a control data for controlling a recording side apparatus, which is a destination of transmission is also multiplexed.

Optimizing operation of a media player during rendering of media files. The invention includes authoring software to create a data structure and to populate the created data structure with obtained metadata. The invention also includes rendering software to retrieve the metadata from the data structure and to identify media files to render. 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.

Grouping and navigating media files within a playlist on a computer-readable medium. Invention software selects media files according to a grouping criterion to define a group from the media files. The invention software generates a group header associated with the group. The group header includes a value identifying the defined group and a reference to another group to enable navigation. The invention software stores the selected media files, the playlist, the defined groups, and the associated group headers on a computer-readable medium. The invention software also includes playback software for navigating and selecting media files via groups within a playlist. 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 formal designed for playback on feature-rich personal computer media players as well as low cost media players.

It has been difficult to replay data in a manner which better suits a user's intention. A recording/replaying system comprises a recording medium 15 on which a plurality of data pieces are recorded, write file managing means 11 which records on the recording medium 15 one or multiple lists which are for selecting predetermined data pieces from among the plurality of recorded data pieces and specifying thus selected determined data pieces, file recording means 14, control means 21 which replays the predetermined data pieces specified by the lists based on thus recorded one or multiple lists, the file replaying means 23, and the data file outputting means 24.
摘要:
An apparatus for recording and reproducing digital data according to the present invention, includes: a group converter; a controller; a recording converter; a recording unit; a reproducing unit; a reproducing converter; and a group reverse converter, wherein the group converter includes: a block management data generator for receiving the management data from the controller and generating block management data with respect to the corresponding blocked data, the block management data having a variable-length and containing information concerning each blocked data; a group management data generator for receiving the management data and generating group management data containing information concerning the entire grouped data; and a grouped data generator for receiving the blocked data, the block management data, and the group management data, and generating grouped data by arranging the blocked data, the block management data, and the group management data in a predetermined order.
