Abstract: In the display device according to the present disclosure, a linear operation mode, in which an image is changed by tracing an operation surface substantially along a straight line, and a circular-arc operation mode, in which an image is changed by tracing the operation surface substantially along a circular arc, are set as operation modes for changing images displayed on the operation surface by tracing an operation surface of a touch panel. A CPU extracts the characteristic manner in which the operation surface is traced based on information acquired from the touch panel when the operation surface is being traced, decides which one of the linear operation mode and the circular-arc operation mode as the operation mode based on the extracted characteristics is the operation mode, and changes to the other operation mode in response to a change in the characteristic manner in which the operation surface is traced.

Abstract: A storage section stores therein one or more sets of music content and/or function executing programs, at least a part of the sets of music content and/or function executing programs being set in a non-usable state at least in an initial state. An audio signal containing additional information is received from an external electronic audio apparatus, and a determination is made as to whether the additional information satisfies a predetermined condition. If the additional information satisfies the predetermined condition, any of the sets of music content and/or function executing programs, stored in the storage section, that is currently set in the non-usable state is updated to a usable state. A model of the external electronic audio apparatus is identified, and any of the sets of music content and/or function executing programs that corresponds to the identified model is updated to the usable state.

Abstract: 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.

Abstract: 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.

Abstract: A song data reproduction apparatus has a storage for song data composed of performance data and order information. The performance data represents a content of a music performance and contains reproduction limiting information for limiting a reproduction state of the music performance. The order information indicates either of a purchase or a preview associated to a usage right of the content of the music performance. A usage right identification section refers to the order information of the song data containing the performance data to be reproduced, for identifying the usage right of the content of the music performance in terms of the purchase or preview. A limiting information read section reads the reproduction limiting information from the performance data when the identified usage right indicates the preview. A reproduction control section controls the reproduction state of the music performance in accordance with the read reproduction limiting information.

Abstract: 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.
