Embodiment explains further details to the present invention below in conjunction with accompanying drawing and embodiment.
The program request of mobile P 2 P need be cut into slices to media file, the main consideration of section from two aspects, and the one, safe consideration, the file after the section is owing to recombinate to original file, so the user is difficult to copy.The 2nd, from the consideration of file P2P distribution, section can guarantee that each burst that the user receives all is an audio-visual synchronization, and the user just can begin to play after receiving several bursts like this.Slicing processes is divided into a plurality of fragments (being referred to as the one-level burst here) with media file exactly; And each fragment generated the burst (being referred to as the secondary burst here) of a plurality of fixed sizes; Each burst comprises head and a data field at least; Head comprise piece description entry and a plurality of frame delineation item, and the data field is used for depositing the corresponding audio/video frames of this burst according to the timestamp order.Through after the fragment process, peer node can obtain different piecemeals by a plurality of nodes from network, and splicing also recovers Media Stream.Peer node is the terminal.
As shown in Figure 2 is media file segment encapsulation form sketch map of the present invention, shown in figure, comprises a plurality of secondary bursts in each fragment, comprises a plurality of three grades of bursts in each secondary burst.In the secondary burst, comprise build, load zones and audio/video frames.In the secondary burst, comprise the build district, the content in the build district comprises size, MD5 value, frame number and the frame delineation item of piece number, piece.Comprise a plurality of audio/video frames in the load zones.Description entry in each audio/video frames comprises the type of frame, length, vertical shift and the frame time stamp of frame.
In above-mentioned burst, the piece description entry comprises: the size of piece number, piece, the number of the audio, video data frame in the data block, the MD5 value of piece (being the value that the content of piece calculates through the md5 encryption algorithm), 44 bytes of needs.The frame delineation item comprises: the skew in affiliated piece of the type of frame, the byte length of this Frame, this Frame, the initial reproduction time of this frame, the finishes time of this frame, need 25 bytes.In view of comprising a plurality of audio/video frames in the piece (a secondary burst), the frame delineation item in such piece possibly also have multinomial, therefore shared 69 bytes of the minimum needs of byte number of build in piece; Therefore in this kind burst mechanism, the definite of the size of secondary burst just seems important, if the secondary burst is too small; Then will certainly cause a large amount of redundant data transmissions of generation in the transfer of data behind burst, thereby can increase flow, cause the waste of valuable bandwidth among the mobile network; And if burst is excessive; Then when network condition is bad, can cause network congestion, influence transmission performance.
The present invention is directed to the problems referred to above; Proposed on the basis of burst, to carry out the burst mechanism of three grades of virtual bursts; Thereby can effectively address the above problem; And can realize making the burst size to be complementary, thereby improving the efficient of transmission with the minimum transmission units of network according to the adjustment of carrying out three grades of virtual burst sizes of the type self adaption of network.
So-called three grades of virtual bursts; It can't carry out any modification to the content of secondary burst; But the unit that carries out data interaction between the mobile P 2 P terminal, promptly portable terminal no longer is to be unit with the secondary burst when each request for data; But a part of data of application secondary burst, such as the data of preceding ten sixths of applying for the secondary burst.Have only after all data of a secondary burst are all applied for data that just can other secondary bursts of continuation application.For each secondary burst, portable terminal can write down this secondary burst and be divided into what three grades of virtual bursts, and how many three grades of fragment datas requests of having sent are the size of three grades of bursts that it comprises have and replied how many three grades of fragment datas.Virtual burst is just realized through this record in the terminal, and need not carry out actual sectioning to the secondary burst.
A files in stream media comprises a plurality of one-level bursts, comprises a lot of secondary bursts in the one-level burst.
For each fragment, it safeguards a BITMAP (bit map) (being referred to as one-level BITMAP), in order to the existence of representing each secondary burst in this fragment situation whether, exchanges periodically this information between the terminal, thereby as a kind of foundation of request of data.Therefore, if burst is too small, will certainly cause the increase of BITMAP data volume, because the BITMAP information between the terminal compares frequently mutual, this certainly will can cause waste of bandwidth again.
And for each secondary burst; It also safeguards a BITMAP (being referred to as secondary BITMAP); The existence that the user representes each three grades of burst that it comprises is situation whether, and this information is not carried out between the terminal alternately, the foundation as just the terminal when carrying out request of data.
How to carry out three grades of virtual bursts and how to carry out request of data according to this burst mechanism, specific embodiments is following:
For the issue of request program, the media file that is used for program request at first carries out burst through the fragment process device, and the granularity of this burst is to the secondary burst, and an one-level burst promptly is a file, after through the operation of reaching the standard grade, leaves in above the compensation server of system;
Virtual three grades of bursts are carried out to the secondary burst in the terminal after the beginning program request, thus corresponding generation two-stage BITMAP, regularly mutual one-level BITMAP between the terminal;
Terminal pins is confirmed three grades of burst sizes to the network type and the network condition of friendly node.
Because the diversity of mobile Internet network type, for every kind of network type, because bandwidth is different, its best transmission unit is also inconsistent, and therefore the size of three grades of virtual bursts also need be adjusted according to network type.For GPRS network,, then can cause the obstruction of network, and,, then can't make full use of the transmission performance of WiFi if three grades of bursts are too small for the WiFi network if three grades of bursts are excessive.
The present invention is directed to GPRS, EDGE, HSDPA; Heterogeneous networks such as WIFI have been confirmed the MTU of best transmission unit (Maxma Transmission Unit MTU), and the size of three grades of bursts can not surpass the size of MTU; For GPRS, the size of confirming three grades of bursts is 64 bytes, and EDGE is 128 bytes; HSDPA is 256 bytes, and WiFi then can reach 1K.
In addition; Because mobile network's fluctuation, the reasonable node of some network condition may become bad in network condition after a period of time, if at this time the size of three grades of bursts is not adjusted; Then may cause the obstruction of network, make network performance worsen.The terminal can be noted this request when certain friendly node carries out the burst request, puts in the request list, and the transmitting time that will ask is simultaneously noted.Request list is regularly detected at the terminal, sees which request is not also returned in the timeout value of default settings in the request list.And, then calculate the difference between the transmitting time of return time and request for the data of having returned.Judge the quality of network condition according to both of these case.If a lot of requests all do not have to reply after sending in timeout value; The timeout value around of perhaps replying; The network condition that terminal and this node then are described is bad; Need to reduce the size of three grades of bursts, make the size of packet request adapt to network condition, in order to avoid cause the more congested of network.
4. terminal data request:
As shown in Figure 3; Play buffer (extra buffer of the deposit data that receives) is at first scanned in the terminal when carrying out request of data, which data sees has apply in the buffering area; But which data is sent application is not also replied; Also have the also not application of which data,, randomly draw one and apply for for the data that also do not have application.
In order to keep the unification of play buffer, earlier play buffer is divided into size here and is the fritter of 16K, and then the piece of each 16K is divided into the fritter that MTU is a unit.Terminal pins is safeguarded two BITMAP to play buffer, and one-level BITMAP representes the situation that exists of 16K data block, is used for carrying out between the terminal alternately, and secondary BITMAP is used for representing the situation that exists of each MTU burst of 16K burst, and this BITMAP does not carry out alternately.
The terminal is when request msg; The situation of scanning secondary BITMAP when finding that certain three grades of burst does not exist, is carried out transmission requests and is distributed; Promptly the own friendly node listing of being safeguarded is scanned, see the upper level fragment data whether these three grades of bursts are arranged among the one-level BITMAP of friendly node.If have, then send request to this close friend's node.
Seeing that the size of the piece of actual slice is 16K; Player is that the basis is carried out data and read and resolve with this size also; Therefore for the piece of a 16K; After having several three grades of bursts to send request therein, then in the burst of data application next time process, should also not have the data of request among this 16K of priority requisition, thereby preferentially guaranteed the integrality of 16K data.According to this mechanism, for the data of a 16K, the terminal maybe be to a plurality of friendly node applications.
5. terminal data receives and handles
For three grades of bursts in the 16K data of each application, after it is replied, do not write buffering area immediately, place but open up an extra buffer, after this 16K data answer is complete, write play buffer more together.
As shown in Figure 4 is the structural representation of player of the present invention, and this player disclosed by the invention comprises and sends out sheet request sending module, burst request receiver module and play buffer module; Can be through point-to-point mode play-on-demand program.The present invention makes improvement on the existing basis that can play the player of P2P request program; Also comprise; Each secondary burst is resolved into the virtual decomposing module of a plurality of three grades of bursts virtually and places the extra buffer module of the answer data that said burst request receiver module receives; Said burst request sending module is periodically sent the burst request constantly, applies for the data of three grades of bursts at every turn, accomplishes the total data of a secondary burst and applies for another secondary burst later on again; Said burst request receiver module receives the answer data of each burst request and deposits in said extra buffer module; After the synthetic complete secondary burst of data set in said extra buffer, more said complete secondary burst is write the play buffer module.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
In sum; Emphasis of the present invention is towards the complicated mobile data network environment of mixing coexistences such as 2.5/2.75/3G/WiFi; Provide that video request program Qos improves one's methods in the mobile P 2 P; Provide the implementation method of three grades of virtual bursts, thereby on original section basis, improved the performance of Network Transmission.Also be directed against mobile network's diversity and fluctuation; Adopted self adaptation to confirm the method for three grades of virtual burst sizes; Effectively satisfy the needs of various network conditions, overcome existing P2P system slice size and immobilized, be difficult to adapt to the multifarious problem of mobile network.On the basis of virtual sliced sheet, confirmed the request mechanism of corresponding data, thereby guaranteed that request of data can satisfy the needs of broadcast.
