the get method of the http and requests the vclick data transmission this request includes information of the time stamp of the reproduction start position of the moving image similarly to the rtp the server apparatus refers to the vclick information file to specify the vclick stream to be transmitted and further uses the time stamp information and the vclick access table existing in the server apparatus to specify the transmission start position in the vclick stream and sends the vclick stream to the client apparatus by the http next at step s 4005 a processing of buffering the vclick stream sent from the server into the buffer 209 is performed this is performed in order to avoid such a state that the vclick stream transmission from the server becomes insufficient during the reproduction of the vclick stream and the buffer becomes empty when it is notified to the interface handler from the metadata manager 210 that the sufficient vclick stream is stored in the buffer the processing proceeds to step s 4006 at step s 4006 the interface handler issues the reproduction start instruction of the moving image to the controller 205 and further issues the instruction to the metadata manager 210 to start the transmission of the vclick stream to the metadata decoder fig4 is a flowchart for explaining a procedure of a random access reproduction start processing different from fig4 in the processing explained in the flowchart of fig4 according to the state of the network and the processing capacity of the server and the client apparatus there.
