Server SV of a contents supplying system according to this invention stores, together with numerous contents, contents purchase information including contents ID information and copy control data of already supplied contents as user information for each user US (a; b) of information processing terminal PC (a1, a2; b1) registered in advance. Upon request for supplying the contents from information processing terminal PC, server SV supplies the relevant contents and renews the contents purchase information of the relevant user by amendment. When information processing terminal PC sends to server SV a request for copying the downloaded contents, server SV sends the copy control data of the relevant contents as a reply. In accordance with the contents of the copy control data, information processing terminal PC determines whether or not to copy the relevant contents into external apparatus KD or recording medium RMb. Thus, the number of times for copying can be restricted, contents by contents, in accordance with a will of the contents supplier without imposing a burden on the user.
摘要:
A first communication device generates a control header containing mapping information indicating channels to which data of time division multiplex is mapped, maps the data of time division multiplex and data of another format to respective channels according to the mapping information, and transmits a signal in which the data of time division multiplex and the data of the other format have been mapped and the control header, and a second communication device receives the signal in which the data of time division multiplex and the data of the other format have been mapped and the control header, acquires the mapping information from the control header, and acquires the data of time division multiplex and the data of the other format from the respective channels of the signal according to the mapping information.
摘要:
A system, apparatus, or method extracts a music playing data file from a given musical work resource such as an electronic music score data file, a printed sheet of music and an audio signals of a musical performance, to be utilized for playing music automatically by means of a tone generator device. The extracted music playing data file is encrypted using an encryption key to be stored in a storage device or to be transmitted to an automatic music playing apparatus. The stored or the transmitted music playing data file is decrypted beforehand to be used for automatic music playing. After the decrypted music playing data file has been utilized, the decrypted music playing data file is deleted from the system so that no unencrypted data file remains in the system.
摘要:
An automatic accompaniment apparatus that enables an external electronic musical instrument connected thereto to exhibit its accompaniment information generating capability to the maximum and makes it possible to set tone color data and accompaniment data adapted to the external electronic musical instrument through the automatic accompaniment apparatus. The external electronic musical instrument stores in advance a plurality of tone color data and/or a plurality of accompaniment data and generates accompaniment information based on the selected tone color data and/or accompaniment data. List information on the stored tone color data and/or the accompaniment data is acquired via a control interface that connects to the external electronic musical instrument and carries out transmission and reception of information to and from the external electronic musical instrument, and the acquired list information is presented to a user. Control information for causing the external electronic musical instrument to set tone color data and/or accompaniment data selected by the user from the presented list information is transmitted to the external electronic musical instrument via the control interface.

摘要:
A selected span of a music composition data file containing note data in the MIDI format which discriminates twelve notes per octave is examined with respect to respective tonalities to find an optimum tonality. Out of all the notes contained in the selected span, the number of notes that fall on the intrinsic notes of a tonality is counted with respect to each of the tonalities. The tonality which has the greatest count of intrinsic notes is determined to the optimum tonality. When the music composition is transposed, the chord names are altered according to the amount of the transposition. Then, the altered chord names are subjected to adjustment in expression according to the musical grammar. Accidental signs are adequately determined from among enharmonic notations.
