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.

Optimizing media player memory during rendering

An optical disc drive device has a metallic exterior casing and an internal unit to be housed in the exterior casing. The internal unit further includes an optical pickup unit for performing recording or reproduction of information signals on an optical disc, and a printed wiring substrate on which a connector electrically connected to the optical pickup unit and serving for transmission and reception of electrical signals from and to external electronic equipment is mounted. The exterior casing has an opening for allowing the connector to be exposed outside, the printed wiring substrate has a ground pattern formed to surround the connector, and a fringe portion of the opening of the exterior casing and the ground pattern are in electrical contact with each other. Thus, radiation noise from around wiring lines contained in the optical disc drive device or the like is reduced.

Optical disc drive device and interconnection structure

An optical disc driving device has a metallic exterior casing and an internal unit to be housed in the exterior casing. The internal unit further includes an optical pickup unit for performing recording or reproduction of information signals on an optical disc, and a printed wiring substrate on which a connector electrically connected to the optical pickup unit and serving for transmission and reception of electrical signals from and to external electronic equipment via an external-connection cable is mounted. The exterior casing has an opening for allowing the connector project outside, and the connector is connected to the external-connection cable in a direction that orthogonally crosses with a projecting direction of the connector from the opening, and the external-connection cable extends from the connector along a surface of the exterior casing.

Optical disc driving device and wiring structure

An optical disc driving device has a metallic exterior casing composed of a first casing and a second casing and an internal unit to be housed in the exterior casing. The internal unit includes an optical pickup unit having an optical pickup part that moves in radial directions of an optical disc to perform recording or reproduction of information signals on the optical disc. At a portion where the optical pickup part moved radially outward of the optical disc makes a closest approach to, in either one of the first casing or the second casing opposed to the first casting, a protrusion for electrically connecting the first casing and the second casing to each other is provided.

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.

Playlist structure for large playlists

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.

Adaptive menu system for media players

There has been a problem that play list reproduction cannot be performed at a data processing level of a CD player and so on which cannot interpret a play list file in an HTML format. A recording and reproducing system has a CD-RW mediumof holding a plurality of data files of storing predetermined data, a file recording meansof recording in a play list fileheld on the CD-RW mediuma play list describing reproduction order of reproducing predetermined data stored by all or a part of a plurality of data files respectively by using a unique contents ID given to each data file, and a file reproducing meansof reproducing the predetermined data stored by all or a part of the plurality of data files respectively based on the recorded play list.
