Abstract

The present invention relates to information processing apparatuses. A content to be checked out is stored in an automatic-checking-out-destination storage section 113 from musical-piece-file storage sections 108-1 and 108-2 for each external-unit/-medium ID which identifies a PD 5. A GUI section 101 determines through a transfer processing section 103 and a PD plug-in 111 whether the PD 5 has been connected. When it is determined that the PD 5 has been connected, a musical-piece file is checked out from the musical-piece-file storage sections 108 to the PD 5 through a musical-piece management section 104, a file search section 106, and a data base 107 according to the information of the content to be checked out stored in the automatic-checking-out-destination storage section 113. The present invention can be applied to music reproduction software.

Claims

1. An information processing apparatus characterized by comprising:

reading means for reading data recorded in a recording medium;

data storage means for storing the data which includes the data read by the reading means;

extracting means for extracting data corresponding to a predetermined condition from the data stored in the data storage means; and

data recording means for recording the data extracted by the extracting means in the recording medium.

2. An information processing apparatus according to claim 1, characterized in that

the predetermined condition includes musical pieces recently listened to, musical pieces checked out a small number of times, musical pieces on a favorite play list, musical pieces selected at random, a play list selected at random, genre designation, and play-list designation.

3. An information processing apparatus according to claim 1, characterized by further comprising condition storage means for storing a plurality of predetermined conditions;

and

selection means for selecting any predetermined condition among the plurality of predetermined conditions, and

characterized in that the extracting means extracts data corresponding to the any predetermined condition selected by the selection means, from the data stored in the data storage means.

4. An information processing apparatus according to claim 3, characterized in that the selection means selects in advance the any predetermined condition among the plurality of predetermined conditions,

characterized by further comprising selected-condition storage means for storing the any predetermined condition selected in advance by the selection means, and

characterized in that the extracting means extracts data corresponding to the any predetermined condition selected in advance and stored in the selected-condition storage means, from the data stored in the data storage means.

5. An information processing apparatus according to claim 3, characterized by further comprising condition storage means for storing a plurality of predetermined conditions;

and

selection means for selecting a plurality of any predetermined conditions from the plurality of predetermined conditions, and

characterized in that the extracting means extracts data corresponding to the plurality of any predetermined conditions selected by the selection means, from the data stored in the data storage means.

6. An information processing apparatus according to claim 5, characterized in that the selection means selects in advance the plurality of any predetermined conditions from the plurality of predetermined conditions,

characterized by further comprising selected-condition storage means for storing the plurality of any predetermined conditions selected in advance by the selection means, and

characterized in that the extracting means extracts data corresponding to the plurality of any predetermined conditions selected in advance and stored in the selected-condition storage means, from the data stored in the data storage means.

7. An information processing apparatus according to claim 6, characterized in that the selection means selects in advance the plurality of any predetermined conditions from the plurality of predetermined conditions,

characterized by further comprising selected-condition storage means for storing the plurality of any predetermined conditions selected in advance by the selection means, and

characterized in that the extracting means extracts data corresponding to the plurality of any predetermined conditions selected in advance and stored in the selected-condition storage means, from the data stored in the data storage means, and

the data recording means records the data extracted by the extracting means in the recording medium such that data corresponding to the any predetermined conditions can be read in a predetermined order.

8. An information processing apparatus according to claim 3, characterized by further comprising recording-medium-identifying-ID reading means for reading an ID which identifies the recording medium, and

characterized in that the condition storage means stores a plurality of predetermined conditions for each ID, and
