The method of handset processes P2P Streaming Media of the present invention specifically comprises the steps: as shown in Figure 4
Be described in detail below in conjunction with network shown in Figure 5 method handset processes P2P Streaming Media of the present invention.
As shown in Figure 5, comprise a P2P streaming media server that is used to issue P2P Streaming Media source in this network, there are 2 mobile phones (first mobile phone and second mobile phone) and a computer to watch same P2P flow-medium performance simultaneously in addition by streaming media server, wherein first mobile phone is a client computer, second mobile phone and computer are peer-to-peer, dotted line among Fig. 5 is represented the contact that mobile phone and computers log-on arrive server, and solid line is represented communicating by letter of P2P stream medium data and agreement.
Be that example is described in detail step 41 with first mobile phone below;
In conjunction with shown in Figure 5, step 41 specifically comprises the steps:
Step 411, first mobile phone obtains the serve port that use TCP or UDP after the access ability of the Internet is connected the P2P streaming media server by the IP network interface module from carrier network, and connects with the P2P streaming media server;
Step 412, P2P streaming media server are the unique identifier number of first handset allocation, and it is joined in the middle of the identifier number table;
Step 413, the P2P stream medium data processing module of first mobile phone inquire about and receive the rendition list on the current P2P streaming media server by the IP network interface module;
Step 414, the specified channel content is downloaded in the P2P stream medium data processing module request of first mobile phone, actual is exactly to require to watch this program, the P2P streaming media server is its assign sessions numbering, and it is added conversational list, return the configuration parameter of watching program, the information of current other players of watching this program and the reproduction time of current program; Wherein this conversational list should comprise the IP address and the port of P2P streaming media server and peer-to-peer;
Step 415, the P2P stream medium data processing module of first mobile phone shows the up-to-date reproduction time in source, and obtains the IP address and the port of peer-to-peer (second mobile phone, computer) by the conversational list of IP network interface module from the P2P streaming media server; Conversational list obtains according to session number; When having known peer-to-peer, the IP address and the port of this peer-to-peer (second mobile phone, computer) also can obtain from known peer-to-peer;
The P2P streaming media server provide playing programs (sequential that broadcast is arranged, promptly be played to content where or the time); The unified content-data of accepting from peer-to-peer or server of numerous P2P Streaming Media clients, therefore these peer-to-peers are according to the present in progress content time of server, the played data that exchanges mutually (that is to say that out-of-date data have not just wanted, only get up-to-date data), general peer-to-peer only keeps up-to-date 2-3 minute played data;
Step 416, the P2P stream medium data processing module of first mobile phone utilizes the IP network interface module to obtain required P2P flow media data packet from second mobile phone, computer;
Step 417, P2P stream medium data processing module send to stream media decoding module after the P2P flow media data packet is combined as the conventional flow media data.
The P2P Streaming Media is that the packet that needs transmit is a lot of little fragments, send P2P DST PLAYER 1 to DST PLAYER n then to, DST PLAYER n+1 can get access to these data small fragments from DST PLAYER 1 to DST PLAYER n there to DST PLAYER n+m so.Any player can obtain the data small fragment there from other player.Player is combined as data according to sequential after receiving the data small fragment, the P2P streaming media server decomposes stream medium data (as the wmv file) and sends peer-to-peer to by the P2P mode, peer-to-peer is reassembled as stream medium data (as being reduced to the wmv file) to the packet of receiving.
Simultaneously, first mobile phone also can periodically upgrade the IP address and the port of peer-to-peer (second mobile phone, computer) in the process of playing, and obtains required P2P stream medium data from new peer-to-peer;
Simultaneously, after first mobile phone stopped to play, the P2P streaming media server was regained session number, and deletes from conversational list.
Certainly, according to the wideband condition and the seed request for information of reality, the P2P stream medium data processing module of first mobile phone also can directly be obtained the content of broadcast from the P2P streaming media server.
Utilize the present invention to realize P2P live streaming media and P2P streaming media on demand at mobile phone terminal.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
