Abstract: A song in a music player is replaced by another song in a server in accordance with the user's estimated preferences without requiring the user to become conscious of individual songs. A music player in a server detects a size of a free space in a memory and a playback history (a substantial playback count, which denotes the number of times a song was continuously played for a duration not shorter than a predetermined one, or a skip count, which denotes the number of times a song was played for a duration shorter than a predetermined one) of every song recording, and judges whether any song should be deleted from the memory to permit a song to be downloaded into the music player from the server. If any song should be deleted, a CPU selects a song having a small evaluation function as the song to be deleted.

Abstract: A song in a music player is replaced by another song in a server in accordance with the user's estimated preferences and wishes and without requiring the user to become conscious of individual songs. A CPU (3) in the music player (30) or a CPU (11) in a server (10) detects or receives the size of a free space in a flash memory (34) and a playback history (a substantial playback count Kp, which denotes the number of times a song was continuously played for a duration not shorter than a predetermined one, or a skip count Ks, which denotes the number of times a song was played for a duration shorter than a predetermined one) of every song recording in the flash memory (34), and judges whether any song should be deleted from the flash memory (34) to permit a song to be downloaded into the music player (30) from the server (10). If any song should be deleted, the CPU selects a song having a small (minus) evaluation function K (e.g., K=2Kp?Ks) as the song to be deleted.

Abstract: The present invention is a reproducing apparatus that reproduces data from a record medium on which text information such as a title of a program is recorded in a plurality of languages and identifiers for identifying recorded languages are recorded as codes wherein a language that has been designated is used as a default language. Thus, without need to designate a language, text information in the default language is automatically read from a record medium and displayed.
