Background technology
Traditional P2P system, essence are that every computer help using in the network is distributed, and have used their bandwidth resources, and only just to support thousands of user's while online with dropping into seldom bandwidth resources.But this framework has individual defective, whole exactly network can only transmit a kind of Media Stream of code stream, so since, in the issue program source, must consider the user of lowest-bandwidth in the network, in ADSL user, the 512K bandwidth arranged, the 1M bandwidth is arranged, if the medium bandwidth is arranged to the 1M code stream, then the user of 512K just can't watch, if but be arranged to the 512K code stream, though all users can both see, test then greatly with corpse and reduce; In addition, traditional video network can be offered different channels for same program, as the clear channel of height, common frequency channel, and also also restricted for user side, download formats also is constant, promptly can only be confined to limited several forms that resource website provides, and a lot of clients can't be visited, hand for example, its supports MP4 form, and it has the requirement of different screen size for the mobile phone of different model, at this moment, for same website, it must provide multiple form.
Summary of the invention
The objective of the invention is to solve the problems of the technologies described above, can only support a kind of defective of code stream simultaneously, utilize the terminal that computing capability is arranged in the access network, collaboratively encode once more and distribute, various stream medium data is provided at conventional P 2P.Under the prerequisite that does not increase server and bandwidth,, provide different code streams, the streaming media service of different size for the various terminal of access network.
To achieve the above object of the invention, the present invention is achieved in that a kind of distributed real-time data-coding transmission method, it is characterized in that: may further comprise the steps;
A kind of distributed real-time data-coding transmission method is characterized in that: may further comprise the steps;
1), at first sets up a p2p network; Contain management server, data server in this network, client, wherein data server provides downloaded resources, and converts resource to the high definition coding; Management server provides the distribution of resource, has transcoding end and the common computer end that can encode once more in the described client;
2) after the client login system, management server reads the customer information of client; Described customer information comprises download bandwidth, computer process ability;
3) client-requested is downloaded;
Whether 4) management server is judged the download capabilities of client, be that the stream sign indicating number that data server provides conforms to, if conform to, then directly downloads from the data server end; If be not inconsistent, management server is searched all online clients, seeks the transcoding end of having downloaded this high definition coding; Described transcoding end is the common computer with certain disposal ability;
5) management server order transcoding end carries out transcoding to this high definition coding by the download capabilities of client-requested, becomes to give birth to secondary coding; Management server sends the address of this transcoding end to client simultaneously; For client downloads;
6) client downloads finishes or logs off, and management server is closed the service to client.
7) in this programme, adopted management server, to managing of client, commander; Thereby commands client is gone the work the same with server, thereby has alleviated the pressure of server, satisfies the demand of different clients simultaneously.
Based on such scheme, our client is diversified, and institute comprises mobile phone terminal, set-top box, the terminal use that common computer etc. are different.
Such scheme is done further refinement, comprise mobile phone terminal in the described client, set-top box, common computer.Utilize the unnecessary processing energy of client common computer, go to handle the demand of some particular client ends, thereby alleviate the pressure of server.Described transcoding end is the common computer with certain disposal ability.
Do further to improve to stating technical scheme, in order to make native system more powerful, compatibility is stronger, and described high definition coding and secondary coding all can carry out transcoding, coding transform more repeatedly.
Described server is classified to client according to the client-side information that reads, and described management server is to classifying to client according to client-side information, and described mode classification does not limit to a kind of mode.This just can make server the fastest, and coherent making a response according to the request of requesting client, reasonably provides corresponding address for requesting client.
Described coding again can be the coding of virtually any size and the code stream of any form.Multi-form with what encode again, deacclimatize multiple multi-form client.
In described the 5th step, management server can order a plurality of clients to be encoded simultaneously simultaneously again, provides a plurality of addresses to requesting client simultaneously.
Described management server is pressed the classification of consolidated network agreement, is divided into different LAN, thereby satisfies the client of different agreements.
The advantage of native system is as follows
1, above system reduces to minimum to the requirement of subscriber terminal equipment:
Owing to need to support more than one multiple terminal, be non-constant and the computing capability of a lot of terminals and network environment are arranged, do not possess the condition that the network service was handled and carried out to data again.In order to make various terminals can both obtain equal service, much calculate and serve and to carry out at server or above the terminal with good conditionsi.Management server all can be accomplished rational distribution in this case.
2, high scalability, the resource of the more multi-format that can provide according to demand:
According to demand or be provided with, native system can provide unlimited many format sources.The characteristics of native system maximum are that different size can be provided, different code streams, even the Media Stream of different-format.Such as using the high definition STB terminal in the family parlor, that it needs is code stream 1M-3M, the high definition media data of size 720P-1080P.But with the client of mobile phone, that need is code stream 100K-300K, the low code stream data of size 240P-480P.
3, high reliability has used measures such as the many copies of data are fault-tolerant, the computing node isomorphism is interchangeable to ensure the high reliability of service.
The resource of a certain form does not have only a terminal that data, services is provided in network, and each task all is to provide service by a bundle of services, has guaranteed the stability and the high efficiency of service.
4, form independence
Transmission not relying on any set form, and the framework that the support of every kind of form is depended on plug-in unit is realized.Such as, what possible set-top box received is 264 Media Streams of 1.5M+1080P form, what may receive on mobile phone is the WMV stream of 300K+240P.
5, virtual sub-network
In this framework, can be according to a plurality of virtual subnets of the dynamic formation of various conditions, such as dividing from various code streams of 200K-1.5M and the virtual subnet of the N from 240P to the 1080P various sizes according to bandwidth and size.Also can divide N virtual subnet according to client's protocol version.And each node can belong to one or more virtual subnet.Virtual subnet can dynamically be set up and dynamically destroy, and uses flexibly.
6, multi-protocols and depositing
Traditional distributed network system (DNS) mostly is to have formulated the fixing agreement of a cover, shakes hands such as connection, and query requests and so on, client must be followed this agreement could access network.The benefit of doing like this is simple and reliable, and is compatible good, but is unfavorable for expansion.And above mentioned, in native system, can be divided into N virtual subnetwork, so just can allow in a network, to exist different protocol versions, help the upgrading and the debugging of agreement.That also allow simultaneously complex protocol and simplify agreement and deposit, be fit to various terminal equipments and use.
