The present invention makes it possible to connect to and communicate with a connect destination by using a temporary number. In the present invention, a temporary number user terminal (100) registers a temporary number acquired from a SIP account server (300) in a SIP proxy server (400), and connects to and communicates with a connected user terminal (200) by using the temporary number. After the communication is finished, the temporary number is unregistered from the SIP proxy server (400), thereby disabling a connection from the connected user terminal (200). Also, connection conditions are provided by specifying the validity period of connection using a temporary number, the number of times connection can be made, the connect destination to which connection can be made, and the like, and only those calls which meet the connection conditions are accepted, thereby making it possible to restrict the uses of the temporary number.

To realize a state in which a decrease in throughput at one place does not affect other transmission destinations while preventing CPU load from becoming high.The present technology can be applied to a multiple point distribution system that transmits a video stream to a plurality of transmission destinations by using a transport protocol having a congestion control mechanism, such as TCP. A transmission terminal transmits the video stream in the same thread (first thread) with respect to receiving terminals A and C in which throughput is sufficient, and transmits the video stream in another thread (second thread) with respect to a receiving terminal B in which throughput has decreased. As a result of adopting such a transmission method, a decrease in throughput for the receiving terminal B does not affect transmission to the receiving terminals A and C. Furthermore, transmission is not performed to the receiving terminals A, B, and C in mutually different threads, and an increase in the number of threads, thus, an increase in CPU load, can be suppressed.
