A computer implemented online music distribution system provides for the secure delivery of audio data and related media, including text and images, over a public communications network. The online music distribution system provides security through multiple layers of encryption, and the cryptographic binding of purchased audio data to each specific purchaser. The online music distribution system also provides for previewing of audio data prior to purchase. In one embodiment, the online music distribution system is a client-server system including a content manager, a delivery server, and an HTTP server, communicating with a client system including a Web browser and a media player. The content manager provides for management of media and audio content, and processing of purchase requests. The delivery server provides delivery of the purchased media data. The Web browser and HTTP server provide a communications interface over the public network between the content manager and media players. The media player provides for encryption of user personal information, and for decryption and playback of purchased media data. Security of purchased media data is enhanced in part by the use of a personal, digital passport in each media player. The digital passport contains identifying information that identifies the purchaser, along with confidential information, such as credit card number, and encryption data, such as the media player's public and private keys. The media player encryption data is used to encrypt purchased media data, which is decrypted in real time by the media player. The media player also displays confidential information, such as the purchaser's credit card number, during playback.

A method is provided for playing back media from a network. The method includes receiving a search criteria from a network enabled device. The method further includes accessing a database comprising a plurality of network addresses, where the database associates each address with one or more classes of information. The addresses in the database each access a media network resource. The method further includes selecting at least one address in the database using the search criteria, and signaling the selected address to the network enabled device. The method also includes controlling the network enabled device so as to automatically access and play back the media resource of the selected address.

A motion detector (1T1) provided for movement with a performer and a control system (1M) for receiving detection data transmitted from the motion detector and controlling a performance of a tone in response to the received detection data are provided. State of a performer's motion is detected via a sensor (MS1) of the motion detector, and detection data representative of the detected motion state is transmitted to the control system. The control system receives the detection data, analyzes the performer's motion on the basis of the detection data, and then controls a tone performance in accordance with the analyzed data. For example, as the performer moves his hand, leg or trunk while listening to a music performance being carried out by a performance apparatus (1S) of the control system, the detector detects the performer's motion and transmits corresponding detection data to the control system, which in turn variably controls the music performance.

A device for programming user-defined information into an electronic device is provided. The programmer allows a user to program customized information, such as user-selected audio, video, or Internet access information into his or her programmable device. Such electronic devices include wireless telephones, pagers, and personal digital assistants. The programmer allows a user to, among other things, customize the device to suit his or her particular taste.

A method is designed for displaying a visual image of a music system that is constructed to play at least one performance part with a particular timbre and that is applied with an acoustic effect, an accompaniment style and the like. The method is carried out by the steps of analyzing data associated to the music system to discriminate the acoustic effect, the accompaniment style and the like applied to the music system and to discriminate the particular timbre allotted to the performance part of the music system, providing a picture of a scenery setting in matching with the discriminated acoustic effect, the accompaniment style and the like such that the picture of the scenery setting visualizes a situation and environment in which the music system should be played with the acoustic effect, the accompaniment style and the like, providing an icon in correspondence to the discriminated particular timbre such that the icon symbolizes playing of the performance part with the allotted timbre, and arranging the icon of the performance part in the picture of the scenery setting to thereby synthesize the visual image of the music system.

A musical tone generating apparatus utilizing a data compression method is disclosed. A musical tone is sampled and is converted into waveform data (S(n)). These waveform data (S(n)) are compressed into compressed data (C(n)) by a linear predictive coding method and further by a differential quantization method. The number of bits of each of the compressed data (C(n)) is thus significantly smaller than that of the waveform data (S(n)). Thereafter, a memory (2) stores the thus compressed data corresponding to an attack portion of the tone and a selected part of a sustain portion of the tone. Hence, it is possible to remarkably reduce the memory storage. When generating a musical tone, the memory (2) reads out the compressed data (C(n)) of the attack portion and thereafter repeatedly reads out the compressed data of the selected part. The read-out compressed data are sequentially decoded into the original digital data. Thus, the whole waveform of the musical tone is reproduced.

A tone visualizing apparatus for visualizing an inputted audio signal to thereby display an image corresponding to this audio signal includes at least a detector, image display (such as a CRT display unit) and display controller. The detector detects characteristics of the audio signal such as envelope, chord, spectrum signal components, number of zero-cross points and energy of the audio signal. The image display displays an image based on given image information which can be generated from a video tape recorder (VTR), a video disk unit or an image memory constituted by a semiconductor memory. The display controller controls the image display so that a display parameter of the image will be controlled based on the detected characteristics of the audio signal. For example, the display parameter can be set as size, brightness or colors of the image. Thus, the image is controlled so that the impression of the image will be matched with that of the audio tone.

A terminal apparatus is connectable to a host station and is responsive to a command to execute an application program to treat music data. In the terminal apparatus, a local storage locally stores an old version of software containing music data and various application programs which are selectively executed to treat the music data. An interface is optionally activated prior to execution of an application program for communication with the host station having a remote storage which remotely stores a new version of software including music data and various application programs which are made available latest by the host station. A controller operates when the interface establishes the communication with the host station for downloading the new version from the remote storage of the host station and for transferring the downloaded new version to the local storage so as to renew the old version stocked in the local storage by the new version. A processor responds to the command for selectively executing the various application programs to treat the music data based on the new version when the interface has been activated and otherwise for selectively executing the various application programs to treat the music data based on the old version when the interface has not been activated. A display graphically presents a map containing various objects corresponding to the various application programs. A pointing tool is manipulated for pointing one of the various objects on the display so as to select one of the various application programs corresponding to the pointed object to thereby input the command.
