Abstract
To provide an apparatus and method for realizing an improved content preview process in a content using mechanism based on content usage-right information. A client obtains default usage-right information (Default Usage Right) when it is registered to a license server, and determines, based on the default usage-right information, whether or not the content can be played back in a content preview process without purchasing the content. The client which is permitted to preview the content is limited to a client which has been registered to the license server to obtain the default usage-right information. This prevents preview-data from being randomly distributed.
