Step 101: transmitting terminal and receiving terminal connect with server respectively, and said transmitting terminal sends stream medium data to said server.
Particularly, transmitting terminal foundation is connected with server, and sends stream medium data to server.In addition, at least one receiving terminal foundation is connected with server, and receiving terminal is set self buffer limiting value and buffering area initial value and also notified said server, and said receiving terminal setting self buffer size is the buffering area initial value.Wherein, the time that said receiving terminal connects, can be before transmitting terminal and server connect, also can be after transmitting terminal and server connect or when transmitting terminal and server connect, this present invention is not limited.
Step 102: the said stream medium data of said server buffer, and big or small according to the said stream medium data size and the said server buffers district of buffer memory, formulate and also send processing policy to receiving terminal.
Particularly, behind the stream medium data that the server receiving end/sending end sends, be buffered in the buffering area of server.In this, the buffer size of said server is no more than the memory size of server self, and said buffer size accounts for the concrete ratio of server memory size, can be provided with voluntarily according to actual needs by server, and this present invention is not limited.Server is the stream medium data size and the server buffers district size of buffer memory relatively; According to said comparative result and above the stream medium data size in server buffers district and the comparative result of rx-side buffering district initial value and buffering area limiting value; Formulate four kinds of different processing policies, and send to receiving terminal.
As stated; When the stream medium data size of server buffer buffer size greater than server; And when the stream medium data size that surpasses the server buffers district was less than or equal to the buffering area initial value of receiving terminal, server sent first processing policy to receiving terminal, promptly; Server directly sends to receiving terminal and downloads notice, and the stream medium data in receiving terminal send server buffering area.
When the stream medium data size of server buffer buffer size greater than server; And the stream medium data size that surpasses the server buffers district is greater than the buffering area initial value of receiving terminal and when being less than or equal to the buffering area limiting value of receiving terminal; Server sends second processing policy to receiving terminal: after the server sets rx-side buffering district size; With the rx-side buffering district size information notice receiving terminal of setting, and the stream medium data in receiving terminal send server buffering area; Perhaps server will be notified receiving terminal above the stream medium data size information in server buffers district, and the stream medium data in receiving terminal send server buffering area.
When the stream medium data size of server buffer buffer size greater than server; And the stream medium data size that surpasses the server buffers district is during greater than the buffering area limiting value of receiving terminal; Server sends the 3rd processing policy to receiving terminal: server resets rx-side buffering district size and is the buffering area limiting value; And with the rx-side buffering district size information notice receiving terminal of setting, and the stream medium data in receiving terminal send server buffering area; Perhaps server will be notified receiving terminal above the stream medium data size information in server buffers district, and the stream medium data in receiving terminal send server buffering area.
If the stream medium data size of server buffer is less than or equal to the buffer size of server, server sends the reason strategy everywhere to receiving terminal: server directly sends to receiving terminal with the stream medium data in the server buffers district.In this, server can be set the broadcast value in server buffers district, and the broadcast value is less than or equal to the buffer size of server.When the stream medium data size of server buffer reached the broadcast value, server sent to receiving terminal with the stream medium data in the self buffer.
