1. A streaming method in which a server transmits stream data to a terminal over a network, and the terminal plays back the stream data while receiving the same, said method comprising:

  • a target value determination step of determining, by the terminal, a target value of the stream data to be stored in a buffer of the terminal in relation to a buffer capacity and a transmission capacity of the network, a delay time determination step of arbitrarily determining a delay time from when the terminal writes head data of the stream data to the buffer to when the terminal reads the data to start playback, by the terminal, in a range not exceeding a value obtained by dividing the buffer capacity by the transmission capacity;

    a step of notifying, by the terminal, the determined target value and the delay time to the server; and

    a control step of controlling a transmission speed based on the notified target value and the delay time when the server transmits the stream data to the terminal over the network.
