P2P is a kind of streaming media transmission technique of low-cost high-efficiency.The idle upstream bandwidth that it makes full use of the user comes assist server distribution flow media content.Under the P2P pattern, be not that all clients are all obtained media data from server, client also connects other clients to be brought in and obtains media data, therefore need not corresponding increase server and bandwidth when increasing the user, thus greatly reduce the load and the bandwidth occupancy of server.
Can realize the online broadcast of online movie by above two kinds of technology, but can have following problem:
Along with the raising of user's appreciation level, requiring has more clearly, and vision, the better multimedia file of auditory effect come to appreciate for the user, so the high code stream file arises at the historic moment.The high code stream file is exactly the bigger file of per second transmitted data amount, and obviously, under the situation of using compression algorithm of the same type, the data volume of per second is big more, and definition is high more; Definition is high more, and the code stream that needs is also high more; And the code stream height, network speed is just not enough.
If the high code stream Online Video is provided, the user who then is lower than this code stream network speed then can not watch; If the low code stream Online Video is provided, then can't satisfy the needs that the user watches the high code stream video program content.
When the high bandwidth user bandwidth is unstable, also can influence the smoothness of video-see easily, influence the experience that the user watches.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and provides a kind of audio visual effect good, can ensure online multimedia file smooth playing under the height bandwidth condition, it is short that used time of client terminal start-up online multimedia file and online multimedia file content switch used time, and the online method of watching multimedia file that can use with CDN and two kinds of technical tie-ups of P2P.
For achieving the above object, the present invention is achieved in that.
A kind of online method of watching multimedia file, can implement as follows:
(1) chooses the high code stream multimedia file;
(2) the described high code stream multimedia file of step (1) is cut apart frame by frame in the transmission source;
(3) mark or preservation component, and form carve information;
(4) client obtains respective component and plays.
The present invention is behind completing steps (3), and client can be obtained single component, and it is play; The capacity of component of the present invention is less than the capacity that is selected the high code stream multimedia file.
As a kind of preferred version, the present invention is behind completing steps (3), and client can be obtained the maximization component, plays after respective component is made up; The capacity summation of cutting apart the back component of the present invention is less than or equal to the capacity that is selected the high code stream multimedia file.
The present invention compared with prior art has following characteristics:
1) the fast user of network speed can watch high code stream online multimedia file clearly, and the slow user of network speed also can smoothness watch the online multimedia file, has satisfied diverse network speed user's needs simultaneously.
2) no matter whether network bandwidth size is stable, can both ensure the smooth playing of online multimedia file, brought good viewing experience to the user.
