The charging method of the streaming media service that the embodiment of the present invention provides realizes on the basis of adaptive stream media technology.Adaptive stream media technology comprises adaptive H ttp Streaming Media (AHS) technology.The basic thought of AHS technology is: the media data code stream producing various code rate at server, and such as corresponding m kind quality, is designated as Q0, Q1, Q2 respectively ..., Qm-1; Often kind of code stream is cut into n fragment, time span corresponding be respectively T0, T1, T2 ..., Tn-1.Adaptive code stream is downloaded and can be realized by two kinds of patterns: server push and final drive, and wherein under the pattern of server push, server is the code stream that terminal selects respective quality according to the feature of terminal and network condition; Under the pattern of final drive, terminal selects according to the disposal ability of self and network condition the code stream fragment downloading respective quality.This adaptive process is along with time variations.Server can produce media and present description (MediaPresentation Description, MPD) file and send to terminal, indicates the information such as the code check of each code stream fragment, Http address in this document.Terminal can do corresponding code stream selection and switching according to this MPD file and network environment and terminal processes.If this media content is protected by copyright, so user side also needs to provide user right data file when playing this media content, and this user right data file is used for deciphering this media content at user side.Usually, user right data file comprises following parameter: content key, term of validity time started, term of validity end time, viewing authority (browse, download, forwarding etc.) etc.In embodiments of the present invention, quality price rate information can be joined above-mentioned media to present in description MPD file or user right data file.
See Fig. 1, the charging method of the streaming media service that the embodiment of the present invention provides, comprising:
Step S101: the quality price rate obtaining the media data code stream of the different quality of same flow media content, the quality price rate of the code stream of each quality determines with reference to the real price of the data code flow of this quality and the relation of standard price, and described standard price is the real price of the data code flow of an extra fine quality of streaming medium content;
Wherein, the quality price rate of the code stream of each quality equals the ratio between the real price of the data code flow of this quality and described standard price.
Step S102: according in playing stream media content process for the quality of the code stream fragment downloaded in each time slice, determine according to above-mentioned quality price rate the paying rate playing this streaming medium content;

Above-mentioned steps S101 can be message accounting to the executive agent in step S104, and this message accounting can be arranged in each terminal, and now this message accounting is only responsible for the Streaming Media billing function of its place terminal; In addition, message accounting also can be arranged in central control equipment, and the message accounting in central control equipment is responsible for the streaming media service billing function of all terminals in network range that this central control equipment administers.
As can be seen here, method provided by the invention adds up the actual cost of playing stream media content in playing stream media content process for the quality of the code stream fragment downloaded in each time slice according to terminal, this changes with regard to making final actual cost consider the expense caused because of the switching of code stream quality in viewing process, makes finally to obtain actual cost fairer and more reasonable.
Specific implementation of the present invention is described in detail below with several concrete example.
Embodiment one
With AHS Streaming Media in the present embodiment, and the download of adaptive stream media data code flow adopts the mode of final drive to be that example is described, and the method comprises the steps:
Step S201: server produces AHS stream medium data code stream, and MPD file.The specific implementation of this step is that the description about AHS technology in current 3GPP standard is existing, only simple declaration here.
Suppose that server produces the media data code stream of m kind quality, m be more than or equal to 1 natural number, the quality of these code streams can be designated as Q0, Q1, Q2 ..., Qm-1 respectively.Wherein, Q0 > Q1 > Q2 > ... > Qm-1.The media data code stream of often kind of quality is divided into n fragment, n be more than or equal to 1 natural number, the time span of these fragments is respectively T0, T1, T2 ..., Tn-1.The code flow structure produced can see Fig. 3.
The MPD file produced can comprise the information such as the quality of media data code stream, time span and address.In MPD file as shown in Figure 4, " Representation " represents the code stream of a certain quality, and " Quality " represents the quality that code stream is corresponding, and " segmentLength " represents the time span of code stream fragment.In practice, by various, the quality of data code flow can reflect that the parameter of code stream quality is weighed, such as, in the code stream code check (PSNR) of every resolution of frame picture, the sample rate of code stream and code stream.It should be noted that, only launch the information of each fragment in MPD file showing m-1 code stream in Fig. 4, in fact certainly also there is the information of each fragment of other code streams in MPD file.
Step S202: the real price of the stream medium data code stream of a certain extra fine quality of server definition same flow media content, as standard price.In practice, the price to the media data code stream of first water in the media data code stream in the multiple different quality of same flow media content generation can be defined, the price of the multi-medium data code stream of central minimum quality can certainly be defined.
Step S203: server is based on the quality height of adaptive stream media data code flow, to the media data code stream definition quality price rate of the different quality of same flow media content, this quality price rate reflects the ratio between the standard price that defines in the price of the data code flow of this quality and step S202, and quality is higher, this ratio is larger; Quality is lower, and this ratio is less.
Such as, if the price of the highest media data code stream of definition quality is as standard price, namely to define quality be the media data code stream of Q0 is standard price, might as well be designated as C.So the quality price rate of the media data of each quality will meet:
1＝R
0＞＝R
1＞＝...＞＝R
m-1＞＝0
In practice, quality threshold Q can be set
t1, just carrying out corresponding charging when being not less than this threshold value for only having the data code flow quality of viewing, so just having following constraints for quality price rate:
R
i=0, if Qi < is Q
t1
Wherein i ∈ 0,1,2 ..., m-1}.
Certainly, also quality threshold Q can be set
t2, the data code flow quality of viewing being calculated higher than adopting identical rate during this threshold value, so just having following constraints for quality price rate:
R
i=1, if Qi > is Q
t2
Wherein i ∈ 0,1,2 ..., m-1}
Step S204: quality price rate defined above is passed to terminal by server, in the present embodiment, quality price rate can join in the MPD file of generation and send to terminal by server.
Thus, quality price rate is joined the new file generated in MPD file and can be called PMPD file by server.
The basis that Fig. 5 shows MPD file in the diagram adds the content of the PMPD file that quality price rate is formed, wherein QualityPriceRate
irepresent the quality price rate that i-th code stream is corresponding, i ∈ 0,1,2 ..., m-1}.
It should be noted that, quality price rate is not limited only to the mode above by PMPD file transfers; Can also be placed in the permissions data file of user terminal and be passed to terminal, usually, user right data file comprises following parameter: content key, term of validity time started, term of validity end time, viewing authority (browse, download, forwarding etc.) etc.; Quality price rate also can be passed to terminal separately in other manners.
Information in step S205: terminal parses PMPD file, obtains the information such as the quality of the relevant code stream had in MPD file itself, time span and address, can also obtain the quality price rate information adding wherein each code stream.
In practice, the numerical value of above-mentioned parameters and parameter can be resolved by parameter identification.
Certainly, if quality price rate information is not join in MPD file, so terminal needs to carry out parsing by the file of Transfer Quality price rate and obtains quality price rate information, if quality price rate information passes to terminal separately by other forms, so terminal only needs the information of resolving this independent transmission can obtain quality price rate information.
Anyway, as long as quality price rate does not join MPD file pass to terminal, what so server sent to terminal is original MPD file, terminal parses be also this MPD file.
Step S206: terminal is to the adaptively selected code stream of each time slice, and the process of this adaptive code stream comprises: the quality according to self, the disposal ability of media data and current network condition (such as bandwidth) being determined to the current code stream that should ask.
Terminal self can by the hardware setting acquisition of information of reading terminals to the disposal ability of media data; And current network condition can obtain by reading network setup information.When two factors carry out the quality determining the code stream that should ask above comprehensive, the quality of the code stream that should ask can be determined with lower in two factors for standard.
The quality of the current code stream that should ask determined should belong to the code stream quality that server defines, such as by code stream quality that PMPD file or alternative document carry, but in practice, the code stream quality directly determined in the disposal ability and the current network bandwidth of considering media data often can not be mated between code stream quality predefined with server completely, and therefore this just exists on earth using the quality of the quality of which code stream in PMPD file as the current code stream that should ask determined.In the present embodiment, the method compared is adopted to determine, particularly, when by considering that the code stream quality that the disposal ability of media data and the current network bandwidth are directly determined is q, then to compare in searching PMPD file in m kind code stream quality closest to this q and that code stream quality being not more than q is exactly the quality of the current code stream that should ask finally determined.Code stream is comprised for the parameter of code stream quality, if determine that the current maximal rate that can process is the media code stream of B by the disposal ability of media data and the current network bandwidth, so by comparing the code check parameter in the quality of the numerous code streams in PMPD file, discovery quality is Q
bthe code check of code stream be that it is maximum to be less than in B, therefore determine that current quality of should asking is Q
bcode stream fragment.
As can be seen here, in embodiments of the present invention, terminal needs the quality selecting the code stream next received according to current actual conditions adaptively.Suppose that final terminal receives whole streaming medium content and completes the selection course of experienced code stream fragment as shown in Figure 6, wherein S
i, jexpression quality is Q
ijth+1 code stream fragment of code stream, the solid line streaked between the code stream of each quality represents the selection track of the code stream fragment selected by each time slice, and the media data code stream finally finished receiving completely by terminal is by S
0,0, S
0,1, S
1,2s
m-1, n-2, S
1, n-1n code stream fragment composition.
Step S207: terminal after for the adaptively selected code stream fragment of each time slice, according to the address downloading contents of this code stream fragment parsed in PMPD file, and can play the content of this fragment.
Certainly, if server is not add quality price rate by MPD file, then, in step S207, what terminal was resolved is exactly MPD original document.
Step S208: terminal, according to the quality of code stream fragment selected in each time slice play at same flow media content, adds up the paying rate p of this streaming medium content.
The mode of three kinds of concrete statistics paying rates can be adopted in the present embodiment, be respectively:
Mode 1: the viewing length of the media data code stream of statistics different code streams quality, its detailed process is:
When terminal pins is to each time slice option code flow section, the quality of record code flow section place code stream and the time span of code stream fragment, finally the quality price rate of all code stream fragments of the selection in streaming medium content playing process is weighted summation according to the weight factor of this quality price rate, obtains paying rate p.When calculating weighted sum, the weight factor of each code stream fragment be the time span of this code stream fragment account for the code stream of whole streaming medium content total time length ratio.
Such as, if T
ibe the i-th+1 by the time span of code stream fragment selected, wherein i ∈ 0,1,2 ..., n-1}.And the total time length of the code stream of whole streaming medium content is T=T
0+ T
1+ ...+T
n-1.
Then the process of above-mentioned weighted sum calculating paying rate can be expressed as:
Wherein, R '
i∈ { R
0, R
1, R
2..., R
n-1be the i-th+1 by the quality price rate of media code flow section place code stream selected.Such as, if code stream fragment S
j, iselected, then in the computing formula of above-mentioned weighted sum, R '
i=R
j.
Mode 2: the switching frequency of the media code flow section of statistics different code streams quality, its detailed process is as follows:
First, when the quality of the code stream fragment selected by adjacent two time slices is different, judge bitstreams switching to occur, in such as, code stream Piece Selection process shown in Fig. 6, when selection the 3rd time slice, due to the 2nd time slice selection is code stream fragment S
0,1, and that following 3rd time slice selection is code stream fragment S
1,2the quality of the code stream at these two adjacent code stream fragment places is different, therefore bitstreams switching occurs.
Then, add up the number of times that whole streaming medium content plays the bitstreams switching occurred, be designated as L.
The number of times of statistics bitstreams switching can have a variety of specific implementation, such as, for often arranging switching mark position between adjacent two code stream fragments chosen, when there is bitstreams switching, can be 1, otherwise be set to 0 by the switching mark position of correspondence.Finally calculate all flag bits and, just obtain the number of times of bitstreams switching.Can certainly arrange a register, initial zero setting, whenever there is bitstreams switching cumulative 1, after all code stream Piece Selections of streaming medium content are complete, the result in this register is exactly the number of times of bitstreams switching.
Then calculate paying rate p, paying rate is the ratio that in the bitstreams switching number of times maximum preset in streaming medium content playing process, the actual number of times that bitstreams switching does not occur accounts for above-mentioned default bitstreams switching number of times maximum.
Above-mentioned default bitstreams switching number of times maximum equals at most bitstreams switching number of times can occur in streaming medium content playing process.
Still for Fig. 6, when the number of the code stream fragment of streaming medium content is n, be not difficult so at most to draw that the number of times that bitstreams switching can occur at most is n-1, namely, the maximum of the bitstreams switching number of times preset is n-1, then the actual number of times that bitstreams switching does not occur is n-1-L.Therefore calculate paying rate to be realized by following formula:
p＝(n-1-L)/(n-1)
Mode 3: the switching frequency adding up the media code flow section of different code check quality, consider the code stream quality gap of switching, detailed process is as follows simultaneously:
First add up with reference to the implementation in aforesaid way 2 number of times that whole streaming medium content plays the bitstreams switching occurred.
Calculate the distance D of each bitstreams switching simultaneously
k, k ∈ 0,1,2 ..., L-1}, 1≤D
k< m.The distance of bitstreams switching can be defined as the absolute value of the difference between the quality sequence number of the last code stream fragment that bitstreams switching place occurs and the quality sequence number of a rear code stream fragment, and the quality sequence number of code stream fragment here determines according to the rank of quality in the quality of all code streams of same flow media content of this code stream fragment place code stream.The Distance geometry of actual bitstreams switching in playing stream media content process is added up according to the distance Dk of each bitstreams switching.
Such as, if the code stream quality of last code stream fragment is Q
i, the code stream quality of a rear code stream fragment is Q
j, then the distance switched between these two code stream fragments is | i-j|, wherein | | be the operation taken absolute value.
Then calculate paying rate p, paying rate is the business that the maximum of the Distance geometry of the switching code stream that can produce in above-mentioned streaming medium content playing process subtracts the maximum of the difference of the Distance geometry gained of actual bitstreams switching and the Distance geometry of the above-mentioned switching code stream that can produce.
When same flow media content has the media data code stream of m kind different quality, when each media data code stream is divided into n segment encode flow section, the situation of the maximum of the switching code stream distance sum that then can produce in this streaming medium content of above-mentioned broadcasting, bitstreams switching (namely actual bitstreams switching number of times is n-1) is all there is between adjacent exactly two time slices, and bitstreams switching carries out (each switching distance is all m-1) all the time between the minimum code stream of quality and the highest code stream of quality, so the maximum of the switching code stream distance sum that can produce just equals (n-1) (m-1).
Particularly, paying rate p can be calculated by following formula:
Or
Step S209: according to the real price of the media data code stream of the extra fine quality of the paying rate p obtained in step S208 and this streaming medium content defined before, i.e. standard price C, calculates the actual cost that user watches streaming medium content.
For the mode of rear paying, system can deduct the actual cost that user watches streaming medium content after user's viewing;
For the mode of pre-payment, system starts first to collect the charges according to standard price, returns the overcharge and demand payment of the shortage afterwards according to actual cost.If such as system is according to the price definition standard price of the multi-medium data code stream of first water, what then user paid when pre-payment will be the highest expense that may pay, and after user's viewing, the actual cost that system-computed goes out is often lower than this mark price, therefore the difference of the two also can compensate to user by system, returns.
It should be noted that, above-mentioned steps S208 and step S209 can be performed by terminal, also can be performed by central control equipment, such as in home network, the central control equipment of this execution step S208 and step S209 can be family gateway equipment in home network, control centre or STB, can realize statistics to the viewing quality of media termination multiple in family and charging like this by central control equipment.
In addition, owing in above-described embodiment being employing final drive, it is the quality being carried out option code flow section by the mode of final drive in step S206, and in the another embodiment substituted, the mode that also server can be adopted to drive carrys out the quality of option code flow section, now will be replaced by terminal in step S206 when playing stream media content, for each time slice, server selects the quality of the code stream fragment of terminal downloads according to the disposal ability of terminal and current network conditions, and indicating terminal downloads the code stream fragment of this quality.
The embodiment of the present invention is the corresponding message accounting providing a kind of streaming media service also, and as shown in Figure 7, this device comprises: quality price rate acquiring unit 701, paying rate statistic unit 702 and Charging Detail Record unit 703.
Wherein, quality price rate acquiring unit 701 for obtain server to same flow media content that different quality media data flow setting quality price rate, the quality price rate of the code stream of each quality determines with reference to the real price of the data code flow of this quality and the relation of standard price, and described standard price is the real price of the data code flow of an extra fine quality of described streaming medium content.
The quality price rate that the quality price rate of the code stream of above-mentioned each quality can equal the data code flow of this quality equals the ratio between the real price of the data code flow of this quality and standard price.
The definition of the detailed process that quality price rate sets and standard price is identical with the related content in said method embodiment, repeats no more here,
Paying rate statistic unit 702 for according to terminal for the quality of the code stream fragment downloaded in each time slice in playing stream media content process, determine according to described quality price rate the paying rate playing this streaming medium content.Determine that the concrete mode of paying rate can adopt three kinds of modes cited in above-described embodiment equally, according to these three kinds of modes, paying rate statistic unit 702 can just like Fig. 8-10 three kinds of concrete structures.
Charging Detail Record unit 703 for obtaining the actual cost of streaming medium content described in terminal plays according to the paying rate obtained and described standard price, and carries out charging according to this actual cost to user.
Product between the paying rate obtained described in Charging Detail Record unit 703 can calculate and described standard price, thus obtain the actual cost of terminal plays streaming medium content.
Below in conjunction with Fig. 8-10, describe the specific implementation of paying rate statistic unit 702 in detail.
