<p>The present invention relates to multimedia music contents service in which sound source and text are synthesized to form one file. In the case where a music file is provided by way of web service by applying DRM being contents protection technology, there is a problem in that a user has to receive sound source contents and text data separately, and cannot compose or machine them. In order to solve this problem, according to the present invention, before DRM is applied, sound source and text are previously composed and are then serviced. According to the present invention, sound source data and text data can be stored in databases, respectively. If requests for a music file are made by way of web service, a corresponding music file is composed and provided by way of web service through DRM. Alternately, sound source and text data can be previously composed and then stored in databases. If requests for a music file are made by way of web service, a corresponding music file is serviced with DRM being applied thereto.</p> |
