<P>PROBLEM TO BE SOLVED: To distribute stream media data by making it into false streams. <P>SOLUTION: A distribution server device transmits voice data and still image data after conversion to a client device by every data transfer period upon converting the voice data and moving image data included in the media data stream distributed from a content server into voice data in a data form which can be reproduced by the client device and a plurality of pieces of still image data by unit of frame. In this case, the voice data and the still image data after conversion is dividedly transferred to the voice data corresponding to reproduction time length matched to the data transfer period, image frame data with reproduction time length matched to the data transfer period and an image archive packaged by approximately averaging the still image data in time. Thus, moving image reproduction by the false streams for reproducing the voice data and the plurality of pieces of still image data while downloading them is allowed in the client device. <P>COPYRIGHT: (C)2008,JPO&INPIT |
