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.

This invention aims to provide a Mobile Communications Terminal (MCT) equipped with a GPS function that automatically transmits the information on the current position of the MCT after the power of the MCT is turned off. The MCT comprises a GPS Receiver Unitfor receiving signal data from a GPS satellite, a Position Determining Unitfor determining a current position of the MCT based on the aforesaid signal data, a Positional Information Transmitter Unitfor automatically transmitting information on the position obtained by the Position Determining Unitand other information, a Controller Unitfor sending a request command to the Positional Information Transmitter Unit, and a Timer Circuit Unitfor turning on the MCT at a predetermined time interval, after power of the MCT is turned off. This invention enables the MCT to automatically transmit the information on the position information and other information of the MCT at a predetermined time interval while the power of the MCT is on, and automatically transmit the information on the position information and other information of the MCT at the a predetermined time interval after the power of the MCT is turned off.

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.

Method and apparatus for reproducing play lists in record media

A reproducing apparatus for disk-shaped recording medium rotationally drives the disk-shaped recording medium at a particular speed to read information from a recording track disposed circumferentially to the center of the recording surface with information recorded at a constant linear velocity. A pickup means scans the recording track and generating a first reproduction signal. A first rotational drive control means rotates the disk-shaped recording medium at a constant linear velocity based on the reproduction signal, and a second rotational drive control means rotates the disk-shaped recording medium at a constant angular velocity. A rotational drive control means selection means selects the first rotational drive control means or the second rotational drive control means based on the position of the pickup means when reproducing the disk.
