When real time communication accompanied with video information of a television telephone, a television conference, etc. is carried out between networks with different transmission conditions (bands, data loss and error correction characteristics), it is possible to minimize displaying video image disturbance on a receiving side due to the different transmission conditions. In a relaying device for relaying communication through networks with different transmission conditions, video image buffer control is carried out in consideration of transmission conditions and characteristics of received video image stream. With this, displaying video image disturbances on a receiving side are eased. A video image buffer control (207) of a relaying device (101) controls a video image buffer (208) in accordance with a control instruction received by an instruction receiving unit (203), a threshold value set by a threshold setting unit (204), and timing set by a timing setting unit (205). Further, the video image buffer control (207) controls the video image buffer (208) per segment unit in accordance with an analyzed result by a segment interpreting unit (206). |
