It corresponds to the image change request from the terminal quickly in the polytopic point video conference server, at the same time, it decreases the computational complexity. Server 300 m book which is selected by the terminal of the n stand (1mn) decodes only the image stream, saves the image stream there is no necessity in the buffer. When the indication which is changed to another stream from the terminal is received, server 300 storing uses the data which it waits in the buffer, goes back to the past and decodes from the direct closely I frame, starts the offer of the image which utilizes the particular image stream.
