PROBLEM TO BE SOLVED: To clearly express a timewise property provided in medium data and to flexibly change a presenting story by describing multi-media data by an object-oriented language as objects. SOLUTION: A presenting story generation means 1 generates the presenting story of the medium data by using a medium object, a delay object, a continuous execution object and a synchronous execution object. A presenting story analysis means 3 analyzes the presenting story, specifies to take an interval for the specified time in the case of the delay object, specifies to recursively call and continuously execute a processing for a list in the case of the continuous execution object, specifies to recursively call and synchronously execute the processing for a set in the case of the synchronous execution object and specifies the execution in the case of the medium object. |
