A musical content utilizing apparatus has a data input portion B, transformation process portion Band utilization process portion Bimplemented via programmed processes. The data input portion Binputs musical content data comprising different kinds of content material data about music and content definition data defining the handling of the content material data. The transformation process portion Btransforms the content definition data in accordance with stylesheets stored in a stylesheet storage portion Bin order to enable the utilization process portion Bto utilize the content material data. The utilization process portion Bgenerates musical tones or displays images in accordance with the input content material, providing a user with musical content. As a result, a piece of musical content is able to be shared among various different types of musical content utilizing apparatuses, i.e., various platforms.

Musical content utilizing apparatus

There is provided a performance information reproducing apparatus that is capable of realizing desired synchronized reproduction of a plurality of types of data, such as music and images with ease. An external storage device stores a musical tone data file, in which musical tone information is recorded, and at least one media data file, in which at least one other type of media information is recorded, together with a management file in which reading manners of the musical tone data file and the media data files are recorded. A CPU generates, based on the musical tone data file and the management file, reproduction data that designates the musical tone information and the media data file to be reproduced, using designation information in a same format as the musical tone information.

Performance information reproducing apparatus and method and performance information reproducing program

An audio encoding transmission system is provided for a transmitting station which performs data transmission with respect to a receiving station through a network. The transmitting station contains a scalable encoder which performs an encoding process on audio signals input thereto in response to bit rate information representing a bit rate which is variable in response to a condition of the network. Results of the encoding process are partitioned into outline data, having a low bit rate, and detail data. Herein, the outline data correspond to low-frequency components of the audio signals while the detail data correspond to high-frequency components of the audio signals, for example. A bit stream is constructed using the outline data and detail data as well as additional information such as a header and a boundary identifier which are created on the basis of the audio signals and bit rate information. Thus, the transmitting station transmits the bit stream to the receiving station via the network. Herein, the transmitting station firstly performs real-time transmission of the outline data with a low bit rate. So, the receiving station performs successive decoding of the outline data to provide successive reproduction of the audio signals. This provides a chance for a listener to give a brief audition to the audio signals substantially without a wait time. Thereafter, the transmitting station transmits the detail data to the receiving station. Thus, the receiving station is capable of performing decoding of the outline data and detail data to provide high-quality reproduction of the audio signals.
