MUSIC COMPOSITION DATA EDITION DEVICE - EP1734505 (A1)

In a music composition data editing device and a music composition data editing method according to the present invention, music composition data comprises at least main data, ending data and connecting data being divided in the time-axis direction, wherein the reproduction time of the main data is calculated in bar unit, the main data is reproduced during the calculated reproduction time, and then the connecting data and the ending data are reproduced sequentially so as to carry out alignment at the start point and the end point of the reproduction time of input video/audio data.    

MUSIC COMPOSITION DATA RECONSTRUCTION DEVICE - EP1830347 (A1)

An apparatus is provided that allows a musical piece to be recomposed by reflecting, for example, the mood, preference, and ambient environment of a listening user in the musical piece in real time. The apparatus includes a rhythm master unit 210 and a rhythm slave unit 220. The rhythm master unit 210 generates synchronization signals SYNC containing a signal having a period corresponding to a measure of a musical piece and a signal having a period corresponding to a beat of the musical piece and also generates musical-piece recomposition information ARI in synchronization with the synchronization signals. The rhythm slave unit 220 
recomposes musical-piece data of input music content in accordance with the synchronization signals SYNC and the musical-piece recomposition information ARI, generates output musical-piece data, and outputs the musical-piece data to the rhythm slave unit 220.

MUSIC COMPOSITION DATA TRANSMISSION RECORDING METHOD - EP1624446 (A1)

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.

MUSIC COMPOSITION REPRODUCTION MANAGEMENT SYSTEM - EP1912204 (A1)

[Problems] To provide a system for promoting user-friendly distribution of music composition data while considering the benefit of an author. [MEANS FOR SOLVING PROBLEMS] When a user operates a mobile telephone (8) to give a reproduction instruction for reproducing music composition content downloaded, the mobile telephone (8) performs reproduction by converting the music content into waveform music composition data. Here, the mobile telephone (8) generates feature data indicating a feature of the converted waveform music composition data (object feature data) . Furthermore, it is judged whether right feature data matched with the object feature data is recorded. If not recorded, the mobile telephone (8) interrupts reproduction. If recorded, the mobile telephone (8) continues reproduction. Thus, only the mobile telephone (8) having the right feature data can reproduce the music composition content.
