Description of the invention: [Technical field to which the invention pertains] ^The invention relates to a peer-to-peer network control system, and in particular to a peer-to-peer network control system of a knife-and-dark media slot case. [Prior Art] The technology for broadcasting multimedia audio and video has been developed for a long time, but hehe. The main reason is the reception of video and audio streams. When there is not enough time, it is easy to cause the quality of the playback to be delayed. However, the transmission of multimedia audio and video often requires 彳艮A ”, ,, and expensive. The bandwidth of I 偎 is large, and the bandwidth is added. Therefore, the multimedia for high-definition video and audio is provided to HDTV devices. ^ such as DVD 480p dedicated WMV, Real Player), etc. by the player software (such as ❾ compression format, after the slot is compressed, 2:: 曰二- if the user (client) bandwidth is not corresponding 2巍. However, the transmission of the case, in other words, the client will still be due to the compression of the multimedia to play the quality of the quality of the game, even = see insufficient, and the guide «breaking and can not play. Peer to peer (Peer to peer ; p2p) network of network technology, its technical application is to use decentralized technology and bandwidth, rather than relying on; road: the computing power of participants p2p network - an important feature is the c feeding device All clients can mention 5 200947948 for resources 'including storage space and computing power. Such networks can be used for a variety of purposes, such as various file sharing software (such as various formats of audio, video or data files) has already begun Universal application. When there are sections added and the system requests increase, the capacity of the whole system also increases. However, although the function of P2P is powerful, if the bandwidth of the user is insufficient (for example, the upload/download rate of 256K/2M) When you can't receive a file, it's a file that emphasizes enamel and sound quality, and often requires more frequent views. Even with P2P technology, you can't make client users © effectively use shared files. The main purpose of the present invention is to make a multimedia file less one-client (10) (four) and the first: client between the communication and the communication between the user and the second client does not need to be more dynamic ^ The above object 'The present invention provides a "" kind of peer-to-peer (P2P) network system, which provides a communication between a first client and a second client' and enables at least one multimedia editing The network 押uc is shared between the second clients. The pair of modules and the two if-way modules further include a client list and a management equation network control group; a buffer list module. Set in two servos丨: On a server, 'and as needed, further' the server includes memory 6 200947948 and the processor 'media segmentation module and peer-to-peer network module storage memory, by processor The media segmentation module and the peer-to-peer network module are executed to achieve the required operation. The media segmentation module is used to mark the multimedia == each, and the case of the building is identified in sequence. The media buffer list module ^ ^ ^ mm is connected according to various multimedia files. When the media media slot is played, the network control system is usually required to include the hot module and the special module to divide the multimedia file; The medium divides the buffer capacity of the multimedia file. The item module first judges that the buffer list module receives the recognition, and the Zen J will be restored. Split the file at least one of them - through: = : = : Rong Rong First information, the first data is clear #筮', through, the network; face to receive, and the customer = ^ - request to enter - step will be - The data is transmitted to the second: the household is the first. - The second client of the client selects the split file received by the first client according to the first request, and the client client selects the client list through the network interface. It is connected to the second client (4) - ^H's second capital invented peer-to-peer network control system, so the network interface system - computer network can be applied to the network interface of various assistants or A mobile phone network interface. The present invention and the other objects, features and advantages of the present invention will be more fully described in detail. The peer-to-peer (p2p) network control system is installed on two servers. Please predecessor 1 (as shown in Figure 3), but it is not used = 叩愔骅 叩愔骅 1 η, ^ 乂 吕 钿, 钿 Refer to Figure 2 'Server 1 () package hidden (10) and processor! 〇b. The media segmentation module η and the pair are stored in the memory - (if installed in the ^, the door cutter group 11 and the peer network module 12, each memory of a different server can be stored). j 别 健 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 凊 媒体 媒体 媒体 媒体 媒体 媒体 媒体 媒体 媒体That is, the peer-to-peer network control system i can mention that the second client 22 and the second client 22 are the first client and the multimedia file 99 passes the road = 3G to reach the communication, and the second client 22 shares the communication. . "The younger-client 21 and those who are aware of the technical field of the present technology, using streaming technology, according to various types of media (four) 99 is a multimedia file 99 usually need to plant or not = media slot format, play the need for the festival There are different buffer capacities, that is, not 8 200947948 ^ If you want, the multimedia file 99 can be played, as long as there are enough sections (pay & multimedia standard 99 (four) punch capacity) to play. Module: Λ equation The network control system 1 includes a media segmentation 12 μ, wherein the packet network module further includes a client list and a management module, a group (2), a 122, and a buffer list module 123. The medium: to divide the multimedia file 99 Into the complex number of points, /, is used to identify the identification in sequence (one heart: case: 99 is divided into several divided files and is marked as A Β two media = / Figure 3 does not 'equipment network control system] more The grouping 13 can be reduced, and the buffering and splitting module 121 and the media stream module 122 are required to determine the multimedia file % in the media segmentation. The list is requested to be linked to the network interface: ❹ is eight. Bu Yi 1 ^, two two cut = several split files are marked 123. & two private is not stored in the buffer list module, for example, when the first user (such as the network interface 30 request download Multimedia file 9 guest ^ call through the list of users and management model, group 121 is still any, έ, 守, according to the customer model, please rely on the multimedia slot 99 to::, body stream cutting file Α _ Ε at least in the basin and in the buffer valley , the multiple households will be transferred to the first end of the household through the network interface 3 and 21. The client list and the management model will receive the first information - the first data essence #笛" will be cut through the network interface 31. The identification of the case, that is, the branch received by the client 21 at this time, the client list and the management module 121 ❹ ❹ 200947948 will record at which client the client 21 has received the split file a split file A -E, for example, there is a second user in the field (for example, _ face 30 requests to download the multimedia slot 99 brother; client 22) through the network 22 has not owned any split file, at this time due to the second client group 121 The first customer moth has been recorded and the client list and The management module 21 has the split file af which split files (for example, the J request, the client list and the management: and); 2 the second client 22 the second client 22, the second guest = (2) the first data transfer Go to = first client 2! request the first data received by =2=虞, that is, the split file client 22 received by the client account 21 should go to the first module m. Notifying the second guest and B. The 21 splits required for the 21 downloads are received - the following: and: the f group 121 is received through the network interface 30 into the split slot case: the poor material is the second client 22 The case...: As the first step client... Customer ^ 22 has also received split files a and B. More in-between and between the cattle to communicate with the essence V: 1 shown in the server 10 and the client 2M5, so that the servo 10 each end / 21_25 can be downloaded first corresponding to the application of the soft body architecture can come : Successful identification. For example, the number of clients 21-25 client 2W5 is shown in the figure 1 or the description. Numerical descriptions are not intended to limit the invention, but are only used to map 200947948. Please refer to Figure 5 for the $ ό. Or 22 through the network f household account flow diagram, when the client 21 client corresponds to the media φ ^ receive the split file, the essence is first transmitted through the group, only to the customer, the terminal slow;; 522 also judged the pile. At this time, the integrity of the client's media stream source file hash and coffee_2 (4), for example, according to the technology: this technical field is public; the case of the f, then the user can: :: 2: memory There is a full buffer list module. Through the client connection, it can also be understood that the buffer list module 123 of the Xuan/Sec. 1 buffer buffer 50 is buffered. What are the sub-divisions (4) and (4) there are their clients, and the client list and management module 121 will record which-partition file A-E. The received feature also includes deleting the received split file A| ft from the first client 21.窜 Dance check 6^ The division received by the client-client 21 ❹ f j is deleted from the first client 21 after a certain time. In the second example, the client buffers the split file in 5G larger than the required = valley ride (for example, two split files), and the file that the client has played is automatically deleted from its buffer. At this time, the buffer list module 523 of the client communicates with the buffer list module 123 of the server 10 to know which split files are deleted by the client, and which ones are stored in the client buffer 50. In general, P2P operations consist of a number of interconnected peers, as will be understood by those skilled in the art, so the technique for p2p is not described here. So staggeredly repeating the 200947948 line on the network, although the client's users are more and more cut into the multimedia file 99, the closer the transfer is to the Okada 2, and the hunting by the cut 1 can make the clear peer-to-peer network control Make the customer ^ user more effective Xiang shared files. In the case where the peer-to-peer network control system 1 is substantially applicable, the network interface 30 can be a computer network, a personal digital assistant's network interface or a mobile phone network. interface. The invention has been disclosed in the preferred embodiments as above, but it is not intended to be used in the sleeves. Anyone skilled in the art can make some modifications and retouchings without departing from the invention. The scope of the invention is defined in the scope of the patent application.
