Abstract: An electronic musical apparatus M1 transmits apparatus ID information and a common page access signal to a server computer SC. The server computer SC receives the signal and apparatus ID information. On the basis of the apparatus ID information, the server computer SC searches a user database 106a to identify the model of the electronic musical apparatus M1. The server computer SC also retrieves content data of a dedicated page for the identified model from a content data storage section 106b. The retrieved content data is created in accordance with display capabilities of a display unit 13 of the electronic musical apparatus M1. The server computer SC then transmits the retrieved content data to the electronic musical apparatus M1. As a result, the user of the electronic musical apparatus M1 can view the information contained in the whole dedicated page in colors on the display unit 13 without the need for scrolling.

Abstract: The present invention is directed to a method and apparatus for making sample contents from music contents whereby server and user are connected with each other via a communication network, whereby the server supplies non-sample regular contents including at least performance information of a music piece and sound information pertaining to the music piece and sample contents including a sample of part of the non-sample regular contents. Thereafter, the user receives the sample contents and test-listens to the received sample contents. When the user has decided on acquiring the non-sample regular contents and performed a predetermined operation to acquire the contents, the non-sample regular contents are distributed from the server to the user via the communication network, at which time unique additional information, such as client information and serial number, is attached to the individual distributed contents.

Abstract: The transmission of sample or regular content such as audio data from a server to a single client over a communication network for test-listening or purchase is disclosed. A user may choose a musical selection for test-listening. The sample content may be a selected representative portion extracted from the regular content. If the user decides to purchase the sampled musical selection, the musical selection is transmitted from the server to the client computer. Additional information supplied along with the regular content identifies the musical selection and provides security. However, this additional information is not supplied when sample content is transmitted. Profile information may be supplied along with regular or sample content. The content may be classified, organized, and selected on a channel-by-channel basis. Regular content may be supplied to the client by downloading, while sample content may be supplied to the client by streaming.

Abstract: Display device is supplied with basic screen display data for displaying a basic screen including a plurality of chord names to be indicated on the basic screen, and displays the basic screen on the basis of the basic screen display data. For example, the basic screen may be one listing names of chords to be used in a selected music piece in accordance with progression of the selected music piece. There is provided a memory storing, for each chord, playing-manner screen display data for displaying a playing manner screen indicative of a model playing manner corresponding to the chord. On the basis of an instruction by a user, a desired chord is selected from among the plurality of chord names indicated on the basic screen displayed on the display device, and the playing-manner screen display data corresponding to the selected chord name are read out from the memory.

Abstract: Server and user are connected with each other via a communication network for bidirectional communication therebetween. The server supplies non-sample regular contents including at least performance information, such as MIDI data, of a music piece and sound information, such as PCM data, pertaining to the music piece, and also sample contents including a sample of part of the non-sample regular contents. The user receives the sample contents via the communication network and test-listens to the received sample contents. When the user has decided on acquiring the non-sample regular contents and performed a predetermined operation to acquire the contents, the non-sample regular contents are distributed from the server to the user via the communication network, at which time unique additional information, such as client information and serial number, is attached to the individual distributed contents.

Abstract: A user accesses a sound data distribution server by operating a client terminal. The sound data distribution server transmits data for displaying a list of distributable music. The data are displayed on a display unit of the client terminal. While referring to the display on the display unit, the user requests the sound data distribution server for distribution of regular music data. This request is issued from the client terminal. A cellular phone to which the regular music data are to be distributed is specified by data (e.g., a mail address of the cellular phone) input at the client terminal. This enables the sound data distribution server to recognize the cellular phone and distribute the regular music data to the cellular phone.

Abstract: A management apparatus stores a use start time and a use period of each of karaoke apparatuses.
